In these projects, groups of two to three Principal Investigators focus on linkages between their individual projects. One small team of researchers is investigating the physical and biological factors controlling larval recruitment to estuaries, another is characterizing nearshore foraging conditions and other factors involved in salmon smolt survival, and a third is assessing the values, perceptions and attitudes of various contin- Researchers met in two groups based on these themes at the All-Hands Meeting held in January. Discussion focused on both details of data integration and ways to weave research results into stories for outreach and educational purposes (see All-Hands Meeting report, page 75). This highest level of integration and interaction is most likely to produce mean- ingful results relative to natural resource management in coastal Oregon and Washington. gents of the coastal community. Because collaborative projects often take on a life of their own, PNCERS has hired 1999 Research Summary three full-time postdoctoral fellows to spearhead these efforts in social, estuarine, and nearshore research, respectively. It is these collaborative projects upon which PNCERS will build our evolving broad scale conceptual models. The independent and collaborative projects work together to describe trends and processes within each primary geographic, or broad disciplinary, focus, i.e. social science, nearshore, and estuaries (represented by large blocks of color in the diagram). Finally, projects address linkages between these disciplinary and regional focus areas, with questions such as: How do nearshore currents influence estuarine water conditions? How do land use patterns impact the estuarine habitat? How do values and perceptions influence coastal management decisions? To facilitate data analysis at these levels, researchers are plan- ning to combine spatial data in a PNCERS Geographic Information System, while the upcoming on-line PNCERS metadatabase will allow researchers to search for multidisciplinary data sources related to each of these categories (in addition to many other areas of interest). In addition to meeting in small research teams, PNCERS investigators have the opportunity to gather as a large group to explore these and many other integrative questions in detail at the weekly PNCERS Eat & Learn Seminars (see Research Program Management, page 71). At the broadest level of interaction, PNCERS investigators have begun formal discussion on two emerging themes of PNCERS research: 1, the broad-scale role and consequences of physical forcing (with primary focus on the nearshore). and 2. the more local interplay between human activities and environmental change (with primary focus on estuaries). PNCERS' approach to understanding natural and anthropogenic change in the Pacific Northwest coastal region is to focus attention on the major processes and key indicators that most effectively illuminate this huge and complex region. Two of the most important processes impacting this area are physical oceanographic cycles and human demographic change. Key indicators include those which primarily reflect the condition of the ecosystem (e.g. seabirds and eelgrass), those which track economic trends (e.g. property values and types of industry), and those which, perhaps most importantly, relate to both the ecology and economy of the region (e.g. the valued ecosystem components: salmon, oysters, crab, recreation and tourism). Major Processes Clearly, physical oceanographic processes are a major influence on coastal ecology. The PNCERS physical oceanographic team, led by Hickey, has been measuring and observing how upwelling and downwelling, riverflow, and seasonal and tidal cycles influence both currents and water properties near and within estuaries. In collaboration with many of the other PNCERS projects, they are helping us understand how these physical processes influence biological aspects of the system, such as the distribution and abundance of plankton patches and fish schools in the nearshore, the movement of phytoplankton (including harmful algal blooms) and larvae into and out of estuaries, and the survival of salmon smolts in both regions. At the same time, the social science team (Huppert, Leschine, Johnson and Bell) has been documenting the human processes impacting this region, including population trends, land use, industry transitions, and the region's institutional and regulatory fabric. Bell has been hired to work with PNCERS natural scientists to understand how these human activities impact coastal ecology, primarily through an exploration of land use and land value models. The social science team is also working to explore how the coastal environment impacts community values and the local economy. Estuarine ecology is significantly impacted by humans, for example, in the form of development, invasive species, commercial oyster growing, crab harvesting, and recreation. On the other hand, PNCERS 1999 ANNUAL REPORT the environment plays an important role in determining why people choose to live on the coast, how property is valued, and what kinds of industry develops (e.g. recreation and tour- predators). These interactions will be used to build a series of spatially explicit bioenergetics models of salmon smolt survival. In addition, Magnusson will consider estuarine pa- ism). rameters that may impact salmon survival. As such, the salmon serve as integrative indicators across several geo- Indicators graphic regions. Influenced directly or indirectly by these major coastal processes are a number of species important for their ecological and/or economic value. Researchers focusing on these organisms observe and document trends in individual survival and reproductive output, and population distribution, abundance, and growth rate, as well as other factors which reflect the general health of local populations. Nearshore indicators In the Pacific Northwest nearshore environment, PNCERS researchers are examining links between three major biological elements of the ecosystem: common murres, fish schools, and plankton patches. They are also looking at the relationship between this rudimentary food web and physical, bio- logical and human-associated environmental variables. Swartzman is comparing the spatial distributions of fish schools and plankton patches. Swartzman and Parrish are looking at spatial correlations between common murre colonies and prey sources, i.e. significant concentrations of schooling fish. Both are examining how population trends for these organisms respond to both spatial and temporal variability in climatological and oceanographic signals (e.g. El Nifio and La Nina events, areas of upwelling and change in average sea surface temperature). Magnusson and Hilborn have assembled a coded wire tag database with which to address questions of salmon smolt survival as a function of environmental change In conjunction with Swartzman and Parrish, Logerwell has recently been hired to use this database to examine correlations between salmon smolt survival and plankton abundance (e.g. the prey), and smolt survival and common murre abundance (e.g. the Estuarine Indicators PNCERS investigators conducting research in Pacific Northwest estuaries are interested in how estuarine ecosystems have changed over time, and to what degree they respond to and are impacted by both physical and anthropogenic factors. Current focus is on understanding major sources of environmental variability in order to establish a framework for understanding possible human stressors. To track how habitat and key species have changed over time, Thom and Rumrill have been mapping estuarine habitat and comparing current data to historical observations. They have also been studying eelgrass as an indicator of estuarine health, as it is responsive to changes in nearby land use, variations in water properties and water quality in the estuary, and climatological signals. To understand variation in the distribution and abundance of benthic biota, Roegner and Shanks are measuring the transport of larvae into and out of the estuaries. The patterns of abundance are being related to oceanographic variables indicative of regional water movements. Armstrong and Gunderson have been documenting changes in distribution and abundance of estuarine macrofauna (with emphasis on juvenile Dungeness crab and English sole), noting which estuarine subregions are the preferred nursery habitats. This study links the pelagic dispersal work of Shanks and Roegner with the habitat work of Thom and Rumrill Finally, in response to the growing conviction that oysters and oyster shell habitat represent important components of coastal estuaries in Washington and Oregon, we will begin a new pilot project (headed by Jennifer Ruesink, University of Washington) to study links between oysters and a suite of native and introduced species. xi PNCERS 1999 ANNUAL REPORT Coastal 'tOcean-Estuary .:417' Coupling Project 1 0 Barbara M.

This leads to large interannual variability in a given estuary as well as to significant differences between Oregon and Washington estuaries. Results & Discussion During the past year of PNCERS we have made substantial progress toward our goal of understanding water property variability in coastal estuaries of the Pacific Northwest. Major accomplishments include the following: For a second year, we have successfully acquired simultaneous data on currents and water properties in Each of these results is discussed in more detail below. I. Data Collection and Analysis Our primary task during the last two years has been to maintain water property and current instrumentation within three coastal estuaries and at two sites on the adjacent coast.

From water are transmitted to the estuary as a gravity current, modifying the along-estuary density gradient and hence the gravitational circulation. New water moves up the estuary at an average rate of about 12 cm s These relationships (e.g., the up-estuary temperature and velocity movement and the salinity-wind stress coupling) are shown in Figure 1.1. Water properties change at a slower rate than the speed of the advancing gravity current, indicating that vertical mixing plays an important role in determining resultant water properties at a fixed location. These results are presented in detail in Hickey and Zhang (2000). Hickey and Zhang (2000). COASTAL OCEANESTUARY COUPLING 3 PNCERS 1999 ANNUAL REPORT Initial comparison of water property data from all three estuaries (see the PNCERS 1999 Annual Report) shows a high degree of inter-estuary correlation during the summer growing season. This similarity is a direct result of the large scale of atmospheric forcing and hence, the occurrence of upwelling and downwelling events along the coast (Halliwell and Allen, estuarine salinities as low as 10 psu. Comparison of salinity at the surface (TP, 0 m) with salinity in the lower water column (W3, 12 m) shows that lower water column salinity fluctuations are correlated to the surface fluctuations, although salinity during the high runoff period is rarely less than 22 psu. Note that the correlation of lower water column salinity to high riverflow events and surface salinity may be entirely fortuitous: high riverflow occurs at the same time as maxi- 1987). Thus, we expect that detailed analysis of the other two estuaries during this season will yield exchange mecha- nisms similar to those described above, although time scales will likely differ from 30 3 26 estuary to estuary as a result of differing morphology. 3.

Contours are drawn at 1 psu intervals. in late spring (May-June). Salinities as low as 14-18 psu are not uncommon (see Figure 1.2). The winter of 1998-1999, in which La Nina. hence rainy, conditions prevailed in the Pacific Northwest, resulted in an extremely high snow pack in by which climate changes can affect both nearshore and coastal estuaries. Moreover, the effect would be limited to Washington's estuaries. Thus, comparison of crab settling rates, phytoplankton growth and other biological indicators Pacific Northwest mountains. Such conditions produce anomalously high runoff conditions in the Columbia River the following spring due to melting snow Thus, in spring between the estuaries during such periods could provide information on the effect of climate changes on Pacific Northwest estuaries and nearshore regions 1999, the plume from the Columbia River was unusually large and unusually fresh. Hydrographic sections across the shelf offshore of Willapa from the Columbia to north of Willapa Bay confirm the presence of very low salinity water from the Columbia River plume just offshore of Willapa Bay during this period (Figure 1.4). Data were collected on a PNCERSsupported offshore survey (processed by Curtis Roegner). Data were Oft; obtained near day 500, just following an upwelling :CtiM event (sec survey dot in Figure 1 3) Wind conditions in May-June, 1999 continued to reflect La Ctotlit Nina conditions; namely, poor weather continued to occur, tcrii catted,. with the associated northward winds that move the Columbia plume to shore (Hickey et al.. 1997). Thus the time series of salinity in the estuary in May-June as seen in Figure 1.3 reflect a period of fluctuating upwelling and downwelling winds. Upwelling occurs, but the amount of freshwater over the shelf due to the Columbia freshet is apparently sufficient to inhibit upwelling of deeper, saltier colder water. Since the Columbia River has essentially no nitrate in spring (it is utilized by indigenous phytoplankton), the lack of deep. nutrient rich water during this rather lengthy period is likely to have had major consequences on the biology of both the coastal region and the local estuaries. In addition to more direct climate effects such as increased or diminished riverflow, or changes in the amount or duration of coastal upwelling, we have thus identified another important route 6 CoAsTAL Oci,..AN-EsTuARY CouPLING Time series of salinity differences over a --20 km distance along the estuary demonstrate that during Columbia intrusions, the "normal- along-estuary density and salinity gradients (denser and more saline nearer the ocean) are near zero or reversed (Figure 1.3, middle panel). Such reversals occurred several times in the 1998-1999 winter to spring period; in particular the reversed gradient persisted for up to 2 weeks at a time in May 1999. We speculate that such gradient reversals may have important consequences for both juvenile fish and larvae in the estuaries Gradient reversals typically were associated with lower water column salinities less than about 22 psu (Figure 1.3, lower panel). Water property surveys collected by DOE during a "normal" high winter riverflow event and a 'Columbia intrusion" are shown in Figure 1.5. The survey data illustrate that in addition to elimination or reversal of along-estuary density and salinity gradi- ents, vertical stratification is dramatically altered by intrusions of Columbia plume water; i.e. vertical stratification is eliminated completely over much of the estuary.

COASTAL OCEAN-ESTUARY Col5PLINc 7 PNCERS 1999 ANNUAL REPORT the three estuaries and along the coast are being exploited in conjunction with PNCERS colleagues to address spatial and temporal variability in fishery year class strength, larval settling rates, fish, zooplankton, phytoplankton distributional patterns and growth rates as well as the occurrence of toxic algal blooms (HABS). Phytoplankton standing stock in coastal estuaries is of vital importance to the estuarine ecosystem and also provides the primary food source for commercial species such as oysters. We hypothesize that oceanically-derived phytoplankton can enter coastal estuaries by two routes: During upwelling events, just as on the coast, seed stock are pulled into the estuary where they are fueled Specific examples of integrations to date in addition to those described in (3) and (4) above include the following. 1.

Roegner and J. Newton Research on processes affecting local estuaries has demonstrated that waters in Willapa Bay exchange with the coastal ocean on a time scale of about 5 days in the main portion of the estuary (see schematic in Figure 1.6). The type of water During downwelling events, just as on the coast, the phytoplankton from the upwelling-fueled bloom are pulled into the estuary and also move up the estuary. This biomass, although nutrient poor and declining rather than growing, may provide a direct food source to the estuary, particularly near the mouth of the estuary. It seems likely that HABS blooms from the coast may enter coastal estuaries via this mechanism, particularly during late fall storms. Any HABS bloom on the coast would also move to coastal beaches during these storms. presented at the mouth of the estuary on flooding tides is governed by the water available near the coast at that time. The properties of that water (temperature, salinity, nutrient levels and phytoplankton content) are governed by whether upwelling or downwelling is occurring along the coast at that time. During upwelling, surface water moves offshore and cold, saltier, nutrient rich water moves upward within a few kilometers of the coast; during downwelling, surface water moves onshore and warmer, fresher, nutrient-poorer water moves inshore and downward within a few kilometers of the coast. In the Pacific Northwest, Data from a PNCERS-supported survey in June 1999 illustrate the rapid transition from downwelling to upwelling con- transitions between these two upwelling states occur at 2-10 day intervals.

During the downwelling event that inevitably follows, the phytoplankton bloom is advected back to the coast. 8 Upwelling Downwelling Figure 1.6. Schematic illustrating baroclinic coupling processes between the coastal ocean and a coastal plain estuary during upwelling and downwelling events for a low riverflow, summer period in an Eastern Boundary system.

Isohalines tilt downward toward the coast during the downwelling event; just three days later, isohalines tilt upward toward the coast (compare Figures 5.4 and 5.5, upper panels, in Project 5 report ). Phytoplankton distributions illustrate the rapid response (i.e., growth) of the biomass to upwelling conditions (compare Figures 5.4 and 5.5, lower panels). Time series of sigma-t in the lower water column within the estuary during this period show the rapid change from downwelling (lower density water) to upwelling (higher density water) consistent with the change in wind direction from southward to northward (Figure 1.3). Time series of chlorophyll within the estuary, although available (from EPA-supported research) have not been processed to date. During the remaining portion of PNCERS Year 3, these data as well as information on phytoplankton species will be incorporated into the analysis and a paper prepared for publication. The hypotheses presented here are unique. Previous work has suggested only that phytoplankton enter estuaries during "wind relaxation" events. Our results demonstrate that this conclusion is likely overly simplistic, describing only half the possibilities for biological estuary-ocean coupling in Pa- least the northern half of the Washington coast may be primarily generated in the Juan de Fuca eddy; b) that during years when intense southward advection in late summer bring this eddy (or portions of the eddy) southward to the Washington coast, c) HABS are swept to the coast if (and only if) the intense southward flow is followed by a fall storm with associated currents strong enough and/or persistent enough to move the bloom across the shelf to beaches (and, in some cases, to coastal estuaries, see above). The components of this hypothesis each require further in-depth examination and analysis. A paper presenting these ideas is in preparation. Time Variability of Larval Recruitment. C. Roegnet; B. Hickey, A. Shanks We have supplied coastal current data to C. Roegner to help interpret larval light trap data at Coos Bay.

Plankton patch density was higher in 1998, an El Nifio year, particularly south of Cape Blanco. We divided the transects into a shelf area (bottom depth < 250 m) and an offshore region. We examined the relative abundance, for both survey years of fish and plankton biomass both in the shelf and offshore regions (Figure 2.2 A and B). From changes in the relative abundance of fish and plankton we divided the study area into three broad regions: I. A southern region from Cape Mendocino, California to Cape Blanco, Oregon. A middle region from Cape Blanco to Cape Lookout, Oregon (45.4N latitude, just south of the Columbia River). A northern region from Cape Lookout to the USCanada border at the Straits of Juan de Fuca (48.3 N latitude). Results from this study have been submitted for publication in proceedings of the Lowell Wakefield Conference on Spatial Modeling and Management in Fisheries in Anchorage, I PNCERS 1999 ANNUAL REPORT AK in October 1999 comparing fish and plankton abundance between the 1995 and 1998 surveys.

Distribution of fish schools and plankton patches for several transects in 1995. Plankton patches are in red and fish schools in blue. The intensity of color in the patch is proportional to the biomass of the patch. Various methods for examining proximity of patches were used to conduct this analysis (Swartzman et al., 1999). We found that on many transects large biomass schools of fish were attracted to large biomass plankton patches near the shelf break (Figure 2 1) this co-occurrence of fish and plank- fish school clusters). This will provide insight to the tors in influencing bird abundance. Acoustic data for 1995 and 1998 are being currently used for this, and future data acquisition of surveys in 1999, 2000 and 2001 will also be used and working with past data from 1992 and earlier (proposed).

Introduction tems, including shipping and oil spills (Burger & Fry 1993), gillnet fishery bycatch (Takekawa et al. 1990, Melvin et al. 1999). and disturbance (Parrish unpub. data). ln sum, murres reflect "bottom up" (i.e. climate and oceanographic). "top down" (i.e. predation), and anthropogenic forces as they alter the coastal environment. Finally, seabirds are highly visible, highly recognizable animals to the public. Because of the IT-S "charismatic megafauna" effect, using information on the factors affecting population change Seabirds, specifically the Common Murre, Uria aalge, are used in PNCERS as indicators of physical change in the coastal environment. Other studies have shown that seabird demography, specifically colony size and reproductive success, are responsive to climate and oceanographic forcing such as El Nino (Wilson 1991), changes in prey availability (Monaghan et al. 1989, Montevecchi 1993), and changes in trophic Julia Parrish structuring as a possible consequence of regional in seabirds to educate the public about the atmospheric forcing (Aebischer et al. 1990). In general, any coastal environment and our effects on it, is a relatively easy upper trophic level predator population exists because it is task supported by the underlying trophic pyramid. Alterations in food web structure, including trophic collapse, will be reflected in upper trophic level variables. Severe change may result in a concomittant collapse of the population, as individuals starve or are forced to emigrate. Subtler changes may be reflected in a change in average annual reproductive In this study, we focus on murres nesting in two colonies: Tatoosh Island, Washington and Yaquina Head, Oregon.

Reproductive success (fledglings/pair) in percent of Common Murres on Tatoosh Island, WA (TI) and Yaquina Head, OR (YQ). Data from Tatoosh are reported as estimated colony-wide success and success in locations least affected by eagles, the dominant predator. Data from Climate Effects Local, regional, and global climate indices indicated that 1997-1998 were El Nifio years, epitomized by warm coastal waters Yaquina are reported as success across all index plots and success in those plots least affected by eagles. (Figure 3.1). For upper trophic species, this may translate into a shift in food web structure and overall prey abundance as primary productivity drops due to a subsidence of coastal upwelling. Unfortunately, there are few direct measurements of primary production, and no measurements of fish abundance to validate this suspected pattern. Seabirds would be expected to experience increased difficulty in obtaining sufficient food, perhaps leading to decreased body condition (usually weight to length ratio), smaller egg and/ or clutch size, and even decreased breeding colony attendance as stressed birds abandon their reproductive effort, skip breeding altogether, or succumb to starvation. At both Tatoosh and Yaquina, colony size and breeding success was far below average annual values in 1998 (Table 3.1). In 1998, breeding was slightly delayed in both locations, and many breeders at Yaquina abandoned their eggs. 1992 1993 1994 1995 1996 1997 1998 1999 TI least 8 20 64 91 36 94 28 63 YQ YQ least 81 15 15 97 28 20 28 28 58 72 4500 4000 3500 3000 2500 2000 1500 1000 500 0 IuIIIIIIIIIJIuI' 91 Due to the intensity of the physical signal, these population-level responses are not surprising.

Eagle presence, the number of overflights, and the num- ber of successful kills has also risen at the Yaquina colony (Table 3.2).

As eagles and Peregrine Falcon populations continue to rebound from depressed levels, a wide range of prey species will be effected.

Both the range of species returned and average fish size appear to be fairly even among years, with the exception of 1997. In that year, murres brought back more species (17) but of lesser size. These data may indicate early effects of the El Nifio altering prey abundance and distribution. Foraging rate data do not seem to echo this pattern (TABLE XX). Since 1996, the average amount of time parents are away foraging has steadily decreased from approximately 3 feeds per day in 1996 to almost 5 feeds per day in 1999. Even in 1996, the rate is comparable with other colonies, indicating that food may be plentiful around Tatoosh even in bad years. 1 Murres are one of the most abundant piscivorous seabirds in the Pacific Northwest. Upwards of one million murres breed along the Oregon and Washington outer coastlines, the vast majority (>950,000) in Oregon. As such, these birds can exert a tremendous effect on coastal foodwebs, both in the nearshore environment as well as in the estuary. Murres and related Alcids have been observed foraging in the large outer coast estuaries of Washington (T. Good pers. comm. to JKP) and have been caught in gillnets in these estuaries (WDFW unpub. data). Simple calculations based on foraging rates and distribution of fish species prey on Tatoosh suggest that during the breeding season, breeding murres and their chicks on the Oregon and Washington coast consume 13,000 metric tons of forage fish in a three month period. Integration & Interaction 1 Seabirds as Nearshore Predators To explore the role of murres in shaping coastal food webs, we are collaborating with two other PNCERS researchers, Gordon Swartzman and Elizabeth Logerwell, as well as with NMFS researcher Ric Brodeur. With Swartzman, we are attempting to link trends in distribution and abundance of plank- ton and small fish, as assessed hydroacoustically, with the numbers of seabirds nesting within a given area of the coast. HI This project is more fully explained in the report titled Plankton Patches, Fish Schools and Environmental Conditions in the Nearshore Ocean Environment Our contribution is to compile: human pressure, as assessed by County level census data These data will then be used to ask what types of factors might explain the unique distribution pattern of murres within the PNCERS study area. With Logerwell and Brodeur, we are attempting to estimate the amount of food murres remove from the coastal system, using a spatially explicit bioenergetics model. Our contribution is to translate our diet and foraging rate data into usable estimates, and combine these data with estimates of total population, by area. In addition, we will attempt to estimate estuarine versus marine-derived food by conducting stable isotope analyses on fresh murre carcasses deposited by eagles. We propose to examine "CPC ratios because 13C shows greater enrichment in inshore or benthic food webs, relative to offshore or pelagic food webs (Fry & Sherr, 1989).

The picture becomes clearer when the survival rates are plotted against release year (Figure 4.4), since most of these coho CWT groups were released at age 2 while the fall chinook smolts were released at age 1. Smolts released into the Columbia River in Oregon in 1985 seem to have had a greater probability, on average, of surviving to adulthood than smolts released in 1984 or 1986. This observed trend is based on 76 CWT groups of two different salmonid species released in 1985 from 15 different hatcheries.

Not only are the hatcheries different now, but these CWT groups were released into different watersheds. This might imply that the reasons behind the high survival rates of release year 1985 lie not in river or estuary habitat, but in the ocean. It is well possible, though, that the Northwest freshwater habitats were all affected by some environmental phenomenon, such as the timing of snow melting or the amount of rainfall. In the worst-case scenario, the survival rates of salmon released in 1985 were affected by some violations of the survival rate estimation. An example of this would be a sudden increase in recovery effort, either by the commercial fishing fleet or stream surveyors. The year 1985 will play no special role in the data analysis; PNCERS 1999 ANNUAL REPORT 5% Coos Bay (n.261) -Willapa Bay (n.32) 4% would describe the SST around the respective estuary at the relevant time for that CWT group, while the other would be a more broad description of the North Pacific sea surface temperature during the CWT group's oceanic life stage. 3% Two variables are being extracted from Gordon Swartzman's zooplankton data, one describing the overall zooplankton abundance close to the corresponding estuary, and another based on the distances between plankton patches.

Inside the brackets is the total number of tag code groups used in calculating the respective averages. this particular observation is only used as an example that touches on many important aspects of the modelling effort. Although not yet fully defined, it is clear that the planned regression is not modelling for the sake of modelling. It is very hard to describe any general trends in the data without modelling, although exploring is a vital part of any data analysis. Part of the difficulty is the sheer scope of the dataset, but so is the varying geographic resolution where trends appear and disappear by changing the "zoom level" Finally, it is possible that the data will be stratified by smaller temporal units than a year, e.g. quarters, to dampen the knife-edge importance of New Year's Day in the data analysis. Even if the CWT data are somewhat slippery regarding the number of anomalies in the database and the assumptions on which the analysis rests, it is very clear that they carry an enormous amount of ecological information about natural and anthropogenic impacts on salmon survival. The key unit in the regression framework will be the tag code, which stands for a group of identically tagged salmon. Each tag code is a datapoint, with one survival rate estimate and many separate predictor variables, both numerical and categorical. Most of the predictor variables will be the results of other separate studies, involving research integration. work. The problem is how recently the zooplankton data became available as a by-product from acoustic surveys off the West Coast. Only one year of zooplankton data, 1995, will be useful in the CWT data analysis. The next year in that dataset is 1998, which is too recent a release year for survival rate estimation. Nonetheless, even the single year of zooplankton data can be statistically useful, for instance in fitting the 1995 residuals of the otherwise final CWT regression model. Salmon smolts are known to be preyed upon by common murres, which implies a negative correlation between survival rate and murre abundance close to the corresponding estuary. With rough extrapolation from Julia Parrish's seabird data, the murre abundance can be estimated as ca. 100 times higher in Oregon than it is in Washington. The exact proportional difference between the abundance in the two states is not critical for the regression, but it needs some more contrast, either in time or space, in order not to be redundant with the categorical variable state. Moreover, there have been a couple of meetings with Elizabeth Logerwell. Some research integration is very likely, but details have yet to be looked into. A loose connection has been made between the CWT database and an Arc View project, copying tables to the latter and creating a point layer of estuary locations. GIS may become a useful angle from which the CWT dataset can be explored with an important geographical overview, which is not offered by the scatterplot format. References Integration & Interaction Some collaboration has already started with four UW researchers, three of which are also PNCERS researchers: Gordon Swartzman, Julia Parrish and Elizabeth Logerwell. The fourth one is Steven Hare at IPHC, who supplied a sea surface temperature (SST) database in Access. Most likely, two separate variables will be derived from the SST data to be included as predictor variables in the regression. One Coronado, C. 1995.

PNCERS 1999 ANNUAL REPORT dition to the up-estuary site maintained by Brett Dumbauld in Willapa Bay. The new deployments were located near the estuarine mouths, and were sampled from March to July. We now have samples that encompass 2 recruitment seasons for sites in Coos Bay and Willapa Bay. In addition, the five light trap sites were sampled coincidently between March and July 1999, during the primary Cancer crab recruitment period. When analyzed, these data will allow both regional and within-estuary patterns of recruitment to be investigated. We are presently counting the many light trap samples, but some preliminary conclusions can be made from the data sorted to date (from the Charleston site). We are observing both species-specific and interannual variation in recruitment patterns, as illustrated by the example in Figure 5.2. Preliminary observations indicate: 1) Larval abundance is pulsed, and is often episodic. For example, annual recruitment of Cancer spp (C. ore gonensis + productus) was confined to a 2 day window in 1998. In contrast, C. magister recruited over a broader period composed of 4 to 7 day periods of enhanced abundance. 2) There is interannual variation in the timing of recruitment pulses, as shown for C. magister in 1998 and 1999 in Figure 5.2 (although this preliminary conclusion is based upon partially completed time series). We have also and 4) pulsed Cancer magister abundance. Note the two larg- est recruitment events are associated with temperature increases in the estuary and current reversals offshore, which may indicate an advective event. These relationships will be more fully investigated this coming year. Cruises Previous cruises on board McArthur and Wecoma revealed information on larval patch size and distribution. We continued participation on the GLOBEC surveys in 1999 (cruises W9902 and W9904); samples consisted of neuston and sub- surface Bongo net tows and CTD casts. Data from these cruises are clarifying the cross-shelf dispersal of meroplankton during different seasons, and in addition we now can compare the physical oceanography and plankton abundance and composition during El Nifio (1998) and La Nifia (1999) conditions. We have processed most of the 1998 samples, and found crab larvae to be widely distributed in the coastal ocean (including off the shelf) during both night and day periods (data not shown). megalopae were sampled as late as November. We do not at In May, we undertook a 10 day cruise off the coast of Grays Harbor and Willapa Bay on the trawler Lady Kay. We sampled a grid of cross-shelf transects, once at the beginning and again after 4 days (Figure 5.1). Fortuitously, this period captured the transition from downwelling to upwelling conditions, and we observed the initiation of a dense phytoplankton bloom. present know the significance of these late arriving Figure 5.4 shows the first series of transects during megalopae. 3) Interestingly, the light trap time series indicate that grapsid crabs recruit predominantly in the winter, when seasonal wind patterns generate downwelling condi- downwelling conditions. Note the relatively flat position of the 10 and 11 °C isotherms and the low abundance of chlorophyll (time sequence goes from A to E). Just 3 days later, strong upwelling resulted in a peak algal biomass >10 mg/m3 (Figure 5.5). Note how the 11 °C isotherm progresses offshore with time (sequence goes J to F), and that the algal bloom is concentrated between 20 and 40 km offshore. We also observed strong gradients of meroplankton abundance in relation to these oceanographic variations. This pulse of chlorophyll, and any associated meroplankton, would be expected to propagate shoreward during wind relaxation where it may then be advected into the estuary. Note that the light discovered that, while the majority of C. magister megalopae recruit between April and June, several small pulses of tions. Cancer species recruitment occurs after the spring transition to upwelling conditions. Megalopae of Pachygrapsus crassipes are similar in size and swimming ability to Cancer magister megalopae, and so contrasting these patterns of abundance in relation to the seasonal variation in oceanography will be informative. In collaboration with Barbara Hickey, we are beginning to assemble the physical oceanographic and biological time series we will use to investigate dispersal and transport processes. An example is illustrated in Figure 3, which compares time series of water level at Charleston (Figure 5.3a), temperature from Charleston and an offshore NOAA buoy (Figure 5.3b), horizontal velocity from the PNCERS ocean mooring off Coos Bay (Figure 5.3c, line), and C. magister abundance (Figure 5.3c, bars). The full dataset will include physical measurements of salinity, temperature and velocity from estuarine and ocean moorings, water level from tide stations, and wind and SST recordings from weather stations. The data to date indicate: 1) no strong relation with tidal period; 2) coincident temperature variations between estuary and nearshore suggesting a synoptic regional forcing; 3) occasional reversals in the mean southward surface current; traps at all 5 estuarine sites were in operation during the cruise, and we will be looking closely at the relation among offshore plankton abundance, light trap time series, and physical oceanographic processes during this period. Integration & Interaction The light trap data is revealing that the supply of larvae to estuaries does vary both within and among years. We also have additional information revealing the patchy nature of the offshore larval distributions. It now seems clear that much of the light trap variability is due to variation in transport of patches from offshore sites to estuarine mouths, at which point LARVAL TRANSPORT AND RECRUITMENT 29 PNCERS 1999 ANNUAL REPORT -20-1 -10 20.. .60 -40 -70 -2.2 D.

While there was no significant difference in fish density between years, there was a significant interaction between estuary and year. This result was driven primarily by the average densities in GH in 1999 which were significantly lower than most of the other yearestuary combinations (Figure 6.2A). Mean English sole density was typically between 1200-1600/ha in most estuaries both years, but was less than half this range (600/ha) in GH during summer 1999 (Figure 6.2A). The resultant estimates of abundance primarily reflect the relative size of the subtid al area in each system (Figure 6.2B). For example, since there is a 20x difference in subtidal area between WB and YB (11,200 and about 500 ha, respectively), the population estimates of about 18 million and < 1 million mirror this ratio (Figure 6.2B). Analysis of variance showed that densities were significantly lower in August (mean = 966/ha, SE = 246) than June (mean 5 0 Coos Bay Yaquina Bay Willapa Bay Grays Harbor Location Figure 6.4. English sole abundance based on subtidal trawl surveys during 1998 and 1999. Data are shown for the June (A) and August (B) surveys in each year, and in most systems there is about a 30-50% decrease in abundance during summer. Retrospective Analyses Dave Eggleston continued to work on infaunal data describing predators effect on species and biomass. Experiments were done in 1992 to define the role of predation in structuring benthic communities in inter- versus sub-tidal habitats, but data only analyzed this past year. As part of his ongoing association with PNCERS, Dr. Eggleston worked with D. Armstrong this past summer and submitted a paper to Journal Experimental Marine Biology and Ecology (in review) in which they concluded that organism-habitat relationships = 1,687/ha, SE = 390), and this trend was conspicuous in June of 1998 (mean of 2000/ha) which was significantly higher than August densities in both years. Such difference in population abundance can be seen in summing mean estimates across all four estuaries, which ranged from a high of 45 million in June 1998, to 21 million in August 1999 (Figure 6.3). Notable change in abundance between June and August is most dramatic in estimates for the large systems (GH and WB) where populations decline about 50% across the 3 months (Figure 6.4). The length of English sole caught ranged from 14 to 200 mm in the 11,720 fish measured in 1998 and 1999. Average length was significantly different among estuaries and months, as well as all combinations of estuary, month and year. The only insignificant terms in the analyses were year (p = 0.099) and the year*month interaction (p = 0.147). English sole were significantly larger in August than in June, as would be expected. But even within the same month, June, mean size of fish was about 33% greater in YB than GH (mean TL =52 BIOINDICATORS IN COASTAL ESTUARIES 35 PNCERS 1999 ANNUAL REPORT and 35 mm, respectively). Such geographic differences in mean size are better portrayed in June size-frequency plots which show more common bimodal distribution of English 0 400000 C 350000 to A sole caught in CB, YB, and WB, but not GH in both years (Figures 6.5 and 6.6).

Analysis of the age 0+ crab densities revealed significant effects of estuary, year, month, and a strong estuary-year interaction. Like the results for English sole, juvenile Dungeness crab are at higher densities in June than August, which reflects high mortality after settlement in May early July. In 1998, there was a geographic dine in density from north to south where means were about 8500/ha and 1000/ha in GH and CB, respectively (Figure 6.7A). In 1999, the jiattern was reversed and overall recruitment much lower than the year before with about 3700/ ha and >500/ha in CB and GH, respectively (Figure 6.7A). High temporal variability in density of 0+ is common and due to time-space dynamics of the coastal larval populations, settlement processes (predation, episodic physical events like reduced salinity) may result in differential survival and subsequent variable population estimates. We hope to work with Dr. Barbara Hickey to explore these hypotheses further using an oceanographic transport model. rine advection were more common to the south off CB in 1999.

However, the geographic pattern of difference across the two years likely depicts real differences in relative entry to, and settlement in the four estuaries, which is reflected in aspects of the Larval Transport and Recruitment project (Shanks and Roegner).

Ghost shrimp E o. GIS Data Preliminary results of the analysis of surveys conducted in GH and WB during 1983-1988 indicates seasonal changes in English sole and Dungeness crab abundance within the estuary. In 1998 and 1999 differences in crab and sole distributions were also apparent between June and August surveys. In Willapa Bay, for example, these changes were most evident in English sole densities concentrated in stratum 2 during June and stratum 3 in August (Figure 6.10A and B). In the case of 1+ Dungeness crab, density commonly differed across strata (subregions) of the estuary. During both June and August 1999, crab density (and biomass) was lowest in stratum 2 adjacent to the mouth (mean about 100/ha) than in strata 1 and 3 (means ranging from 400-88/ha; Figure 6.11). Seasonal changes in distribution, as well as general distribution patterns in the four PNCERS estuaries suggest that differences in habitat within the estuaries may control abundance of our estuarine indicator species. Ongoing fieldwork and data analysis in a GIS data framework will provide an important method to answer this central question: what types of habitat delineations are important in determining how many crab or English sole are produced in estuarine subregions that can be characterized by shared abiotic and biotic attributes? Intertidal Predator-Prey and Recruitment Dynamics In an effort to more completely characterize the role of intertidal shell habitat in life history of key fauna, Kris Feldman and Brett Dumbauld finished analyses of settlement experiments and post-settlement monitoring of 0+ ghost shrimp (Neotrypaea californiensis) and mud shrimp (Upogebia E 150 .c Lo 100 - 70 60 - 0 0 0+ other adult bivalves juvenile bivalves bivalve recruits 50 o. 40 co 30 - m .c 30 co 20 E 10 0 0 Mud Subsurface shell Epibenthic shell Mya Shell Substrate 0 open cage control cage Treatment Figure 6.12.

Density over time was compared across open mud, mud with subsurface shell about 8-10 cm deep, epibenthic oyster shell used for crab mitigation, and "natural" surface deposits of Mya. Data indicate that the two species behave/survive differently (Figure 6.12). Ghost shrimp settle and survive at much higher densities in open tideflats, while mud shrimp do much better in surface shell deposits. We hypothesize that ghost shrimp do poorly in shell either because it serves as a physical barrier, or supports high density of predatory 0+ Dungeness crab when this shrimp species typically settles in late summer.

This same spectrum of themes has brought us into collaborative planning with Ted DeWitt and Pete Eggleston to describe relative effects of predators (generally sculpin, crab, crangonid shrimp, and wading birds) on density and biomass of intertidal infaunal prey (mainly bivalves and polychaete worms). Results show that prey standing stock is very high (bivalves alone > 50g/m2 ash-free-dry-weight, AFDW, Figure 6.13), and that a predator guild may not de- ated in future years. We are working to compile existing information on benthic production in the intertidal zone. Using this information, we hope to apply energetics-based models to back-calculate the level of productivity required to sustain standing stocks of the dominant predators. We also plan to initiate a program of infaunal sampling in the little known subtidal area. We remain very interactive with several scientists whose pro- grams bear on topics of estuarine predator-prey systems, trophic web relationships and models, and key species as drivers within the systems. As noted in the introduction, collaboration with Brett Dumbauld provides an ongoing link to the oyster-eelgrass-crab-shrimp conundrum that manifests Eldridge at EPA, Newport, to adopt their trophic models based on nutrient flow for analogous intertidal systems in WB. plete such resources as bivalves.

Integration & Interaction Oceanographic Modeling In 1999 we initiated work with Dr. Barbara Hickey to model surface transport in the California Current during the English sole pelagic egg and larval stages. Dr. Hickey has provided us with a model that calculates alongshore transport based on wind speed and direction, and has worked closely with us to apply the model. We continue to work on acquiring the data needed to run the model, and refining it to apply to time periods where English sole eggs and larvae were in the surface waters. Light trap sampling by Dr. Curtis Roegner may have captured significant numbers of larval English sole during estuarine sampling in 1998 and 1999. With his cooperation we will sort those samples to determine an index of the recruitment timing of the English sole to the PNCERS estuaries. Combining these data with the oceanographic model provided by Dr. Hickey should provide insight into the transport of English sole eggs and larvae and Dungeness crab larvae from spawning grounds to juvenile nurseries in estuaries. Estuarine Ecology and GIS The relative importance of intertidal and subtidal habitats in 40 BIOINDICATORS IN COASTAL ESTUARIES ton, Barbara Hickey, Curtis Roegner, Alan Shanks and Brett Dumbauld are major architects of this emerging program. We see tremendous opportunity to merge the new WRAC Essential Fish Habitat program with ongoing PNCERS logistics to broaden our research questions within WB and CB, particularly. Both programs will blend for the first time in summer, 2000. We hope that results from these studies on ecosystem processes will greatly augment modeling that may be supported in a new national Sea Grant-EFH proposal by a team of PNCERS scientists collaborating with others at NMFS, Newport (now in review). We also plan further collaboration with colleagues working on the Institutional Mapping and Ecosystem Management project (Huppert, Bell, Leschine) to devise further means of using species-ecosystem information for economic analyses related to their program missions. In all cases, we are now moving to place our data in a GIS context, and support any collective PNCERS decision to make this a central element of the overall program. Virtually every aspect of data inventory, analyses, and future modeling will benefit from a common GIS structure that Amy Borde, Dana Woodruff, and Ron Thom have begun as part of the retrospective habitat analyses.

Thom and Steven Rumrill the Social/Economic assessment group for further analysis. Introduction They will provide data on upland development in a GIS The overall goal of the format, which will allow direct comparison with the changes noted in the estuaries. Habitat/Bioindicator Study is to provide resource managers and decision-makers with information about habitats that Ronald Thom and Steven Rumrill is useful for making management decisions about coastal estuaries in the Pacific Northwest. To achieve this goal, the study is addressing two broad objectives: To understand and document Eelgrass (Zostera marina L.) has been the primary focus of our work on spatial and temporal patterns. Eelgrass is an ideal indicator of estuarine "health" because it forms meadows throughout much of all coastal estuaries in the region, harbors large numbers of fisheries species, is a nursery and feeding area for juvenile salmon and Dungeness crab, and responds to physical and chemical forcing factors through changes in its size, morphology and distribution. To evaluate interannual variation, in 1999 we repeated sampling conducted in 1998 large-scale changes in primary benthic habitats that have taken at all six eelgrass sites in Willapa Bay and four sites in Coos Bay. In addition, we added sampling for burrowing shrimp density. This information was gathered to try to assess the rela- place in the target estuaries through retrospective analysis. To understand and document the factors responsible for spatial and interannual dynamics of selected tionship between eelgrass and bur- habitats through directed field and laboratory studies. by eelgrass in the systems. These data rowing shrimp. We also gathered data on the range of elevations occupied assist managers in predicting elevations that should be avoided for development and help define the limits of eelgrass to determine the best sites for eelgrass restoration projects. Fi- 200 By accomplishing these two objectives, we will be able to provide man- agers with credible indicators of the types and relative impacts of stres- sors affecting estuarine habitats. Within PNCERS, the habitat studies form a key link between geophysical conditions in the system and quality of the estuarine system for a variety of fisheries resources. Because of these close linkages, the habitat stud- e Cr, -....0' 150- = 4r.' 4 nally, by sampling along a gradient between the upper and lower estuary, we too - 4 45 are developing an understanding of .= the spatial patterns in eelgrass metrics. o cn :1111j11111 e 5 Z ies rely heavily on data gathered by nid populations, and physical/chemical processes.

The results of the retrospective analy- sis, reported in the last annual report, indicated that largescale changes had occurred in all estuaries. These changes included loss of intertidal marshes and eelgrass through filling, diking and dredging operations conducted near developing ports in the estuaries. These data, which are in Geographic Information System (GIS) format, were provided to 42 c" 3" other PNCERS program components, including investigations of Dungeness crab, English sole, and salmo- :411 This understanding can also be used to assess anthropogenic impacts on eelgrass within the context of natural spatial variation. HABITAT LINKAGES AND RETROSPECTIVE Results & Discussion Eelgrass Abundance The same general patterns in eelgrass biomass and density seen in 1998 were documented in 1999 (Figure 7.1). In general, Willapa Bay eelgrass was less dense than in Coos Bay. However, above ground biomass was similar be- tween the two estuaries. The reason for the difference between the two estuaries is still under investigation. We have documented cooler water temperatures in Coos Bay as compared to Willapa Bay, which may explain the greater densi- PNCERS 1999 ANNUAL REPORT 450 ties.

In Willapa Bay, the densest meadows occurred at intermediate sites located at Nemah, NW Long Island and Lewis Slough. Patterns in 1998 were similar to those observed in 1999 suggesting that there is consistent spatial difference spatially throughout both estuaries that force measurable differences in the eelgrass population throughout both systems. We suspect that salinity and temperature are key factors controlling this spatial pattern. 150-. 100_ 50 0_ 0. 3 P- Willapa Coos Bay Figure 7.2.

This may indicate stronger upwelling and nutrient supply to the systems as well as less desiccation stress. This strong regional signal of increased biomass reflects an increase in productivity, which is ultimately important to and reflective of ecosystem productivity. Flowering Flowering was again greater in Coos Bay than in Willapa Bay (Figure 7.3). 125 zone at Coos Bay. Potential explanations for this feature are that the flats in Coos Bay remain moister than those in Willapa Bay, thus preventing drying of the plants at low tide. There also may be a stronger freshwater signal at the surface in Willapa Bay, which could limit its extension into higher elevations. We will be exploring some of these factors in subsequent years. The data do assist in the development of a stronger biophysical understanding of the factors controlling eelgrass distribution not only horizontally along the estuarine gradient but also along the Interestingly, flowering was much vertical gradient. These data could greater in 1999 as compared to 1998 in 75 both estuaries. The spatial patterns in flowering shoot density, with the most 50 upstream site (i.e., Cooston Channel) in Coos Bay containing the greatest flowering density, indicates that this site is subject to factors consistent between years in producing more flowers than other sites. Again, salinity and temperature may be proving to be important factors driving flowering. The ultimate effect of increased flowering is seed pro- duction and seedling production. We would predict that eelgrass shoot density would be greater in 2000 owing to the fact that more seeds were introduced into the system in 1999. help managers site development in areas not likely to contain eelgrass. 25 0 nfl ri Burrowing Shrimp Burrowing shrimp are a major compo- nent of most outer coast estuaries in the Pacific Northwest. They can be re- < Willapa Coos Bay sponsible for massive reworking of sediments, alterations in nutrient cycling, and elimination of some other species. Their interaction with eelgrass is still understudied. In 1999, we found burrows (an indicator of shrimp) at Figure 7.6. Mean shrimp burrow most sites, with the Toke Point site con- density at the 10 sites in 1999. taining by far the greatest densities (Figure 7.6). As yet we have no definitive explanation for the high abundances at this site relative to the other sites. 250 Ulva Cover The green seaweed Ulva spp. occurred in very high abundance in Coos Bay with very little noted in Willapa Bay The general negative correlation between burrowing shrimp burrow den- (Figure 7.4). Ulvoids are often associated with areas of high nutrient inputs and can be indicative of eutrophication. Ulva was generally in very high abundance at the more marine sites in Coos Bay and was far more abundant at these sites in 1999 as compared to 1998. The Bar View site is located very near areas of high commercial and private shoreline development. It is also the site that sity and eelgrass shoot density suggests a negative interaction between these species (Figure 7.7). Our impression is that eelgrass, once established, can 50 100 150 200 250 300 Eelgrass Shoot Density (no/sq.m) Figure 7.7.

Depth Distribution The depth distribution of eelgrass was measured at approximately 300 points in 1999 (Figure 7.5). In general, eelgrass Temperature reaches its greatest density between +1.0 and 2.0 feet (MLLW). Our study sites are centered in the middle of the densest eelgrass in both systems. Eelgrass penetrates deeper in Willapa Bay, and appears to extend higher in the intertidal 44 HABITAT LINKAGES AND RETROSPECTIVE Temperature was measured approximately hourly between Summer 1998 and Summer 1999 site visits using Hobo temperature monitors (Figure 7.8a, 7.8b, 7.8c).

Using this information we plan to char- acterize water property conditions at all 10 sites to better understand the factors forcing spatial and annual variations in eelgrass metrics. This information will be useful to managers to help interpret interannual and spatial differences seen in eelgrass and potentially other resources in their systems. Conclusion There are strong patterns that are emerging in eelgrass metrics both spatially and temporally within systems but also between systems. The patterns appear to be consistent between years within each site, and along the estuarine gradient. Increased flowering and shoot abundance in 1999 over that in 1998 points to the fact that the primary productivity of these systems varies substantially. Monitoring of temperature as well as other properties of these systems is promising in terms of interpreting the factors most responsible for the patterns. We are beginning to explore links between changes in benthic primary productivity and secondary production through discussions with other PNCERS team members. Continuing the present monitoring through one or two more years should yield even stronger and more enlightening relationships as yet undocumented in coastal estuaries of the Pacific Northwest. Although we did not deal with these in this report, there were three distinct "disturbances" affecting our study. First, the study is spanning a period from a strong El Nino event to a strong La Nina event. This is seen in the temperature record and may explain the large interannual changes encountered. Second, the New Carissa oil spill at the mouth of Coos Bay, although not impacting our sites directly, resulted in damage estuaries. This has involved some meetings through the year and the exchange of GIS data layers that we have produced during the retrospective analysis. We expect to work further with these individuals to try to refine the interpretations of changes. We are acquiring data sets on water properties from the water column monitoring group (Jan Newton) for use in our analysis of factors affecting eelgrass metrics in Willapa Bay. We have provided our Hobo temperature monitoring data to the physical oceanographic group (Barbara Hickey) for their use in interpreting the effects of the flats on water temperature. We are discussing with the benthic invertebrate and fish group (Dave Armstrong) the incorporation of their data into our GIS system in order to make overlays of habitat and fish and crab abundance in the estuaries We continue to collaborate with the UW-based group (Dave Armstrong) studying the effects of oyster aquac- ulture on eelgrass and juvenile salmon. We are providing assistance in eelgrass sampling and interpretation of results. We are continuing our study in Tillamook Bay looking at interactions of oysters, eelgrass and burrowing shrimp for the National Estuary Program. This study should further refine the information on the relationship between eelgrass and burrowing shrimp as well as the effects of oyster aquaculture on eelgrass. booming activities. These impacts were caused by boats We have ongoing discussions with estuarine researchers at the US EPA Newport Laboratory (Ted DeWitt) regarding their investigation of eelgrass and burrow- gouging the sediment when moving the booms. We will follow recovery of this site in subsequent samplings. Finally, a long line oyster culture system was established over part of ing shrimp ecology. We will supply them with our data which can be used to assist in their development of an eelgrass model. at an elevation slightly below our study site at Bar View from our study site at Toke Point. We recorded no measurable effect of this operation so far on the eelgrass at the site. This represents a great opportunity to study the longer term effects of this type of oyster aquaculture on eelgrass.

Proximity to a major road appears to have a negative effect on residential property values. Overall, the suite of land use variables had mixed effects on residential property values and the significance of distance to the coast, distance to Grays Harbor, and surrounding land uses. Surrounding land uses were measured by drawing circular land use buffers around the parcels (with a 0.75 mile radius) and identifying the different types of land surrounding the Table 8.2.

The final variables included in the model from these buffers are the percentage of area falling within established land use types. Table 8.1 presents the definition of variables used in the property value model and their descriptive statistics. Because of multi-collinearity between several of the ecological variables, only the land use variables were included in the final run.

We believe the value of living near the estuary is captured partially by the water and wetland variables and find their positive signs encouraging. While the five land use variables are jointly significant using all 3 functional forms, we are not content with the present results. A next set of hedonic runs will focus only on the coastal portions of Grays Harbor County. These future runs on a subset of coastal properties will scrutinize the potential influence of more ecological factors on residential property values. This subset of transactions will allow for more detailed environmental variables to be included in the model, and we hope this change of scale will broaden the types of ecological variables that can be considered and, in turn, increase their prominence in the models. In doing so, future In this first county-wide model, ecological variables were represented by the percentage of land in different uses surrounding the parcel. We intend on expanding the consider. ation of ecological variables. In the county-wide model, we runs may involve greater levels of integration and use of data being collected by the PNCERS natural science research projects.

ECOLOGICAL-ECONOMIC MODELING 51 PNCERS 1999 ANNUAL REPORT the first study area because it has a parcel level GIS database system in place that documents the specific locations of par- cels. In the future, we hope to contrast the results found in Grays Harbor County, Washington with a county in Oregon. Population, Land Use, and Human Activities In addition to the property value modeling, we also spent time developing a Geographic Information System (GIS) whose focus is human and management activities. Data on the location of human activities that are potential stressors to the coastal ecosystem and related management activities are being assembled. One early focus of this effort was the creation of a spatially explicit database of population and land use in the five PNCERS estuaries. Past research completed as part of the Socioeconomic Baseline and Institutional Mapping Project relied on county-level data. The more detailed data display some interesting traits about the different estuaries. Observing the 5 counties that are most strongly related to the 5 PNCERS estuaries (from north to south, Grays Harbor and Pacific Counties, WA; Tillamook, Lincoln, and Coos Counties, Oregon), the Oregon counties as a group are more populated and densely settled along the coast than the Washington counties. Development in coastal Washington is largely limited to the areas near Grays Harbor and Willapa Bay. In contrast, development is more persistent along the Oregon coast. This difference may be partially explained by the higher level of accessibility to the Oregon coast. The distribution of major roads and employment centers in western Oregon parallels the coast in many sections. This same distribution is not found in Washington. Within 5 miles of the coastline, the 1997 population levels were approximately 44,864 in Washington and 112,803 in Oregon. We are examining these differences in population, land use, and devel- opment patterns to characterize basic indicators of human stress (population density) and to allow for the prediction of future changes in population and human activities. counties are quite similar, with the majority of their land being in forest uses (greater than 80 percent in all cases), followed by small areas of agricultural, water, and developed uses. There is more variation across these areas when the coastal land uses are assessed. While forest remains a dominant land use in the coastal areas, several other uses (agriculture, residential, and commercial) account for a higher por- tion of the area along the coast than they do in the countywide assessments. We are exploring these data to consider questions such as: Does the management of the estuarine resources in the PNCERS study area reflect and/or affect these distributions of land use? And: Are there correlations between land use patterns and the health or condition of select estuarine resources (e.g., habitat, seabirds, salmon, crab) being studied by PNCERS natural science investigators? In addition to the population and land use information, other types of spatially explicit data that are linked to potential stressors on the coastal ecosystem are actively being collected for the counties falling in the PNCERS region. For example, these data include: sources of various pollution discharges, agricultural activities, oyster culture, shoreline modification/ hardening, dams, and port activities. These data are being integrated with other information sources such as United States Census demographic and economic data, United States Census Tiger Line file data, USGS land cover and slope data, and various state and county GIS data resources. Integration & Interaction In collaboration with Ron Thom and Steve Rumrill, we intend to develop a broader understanding of the factors that Table 8.3 displays the number of acres and percentage of have influenced historical habitat changes in the PNCERS area by land use type for the 5 PNCERS counties.

The linkages between various resource users and "external" institutional controls can be characterized as property rules, regu- lations, legal constraints, or contracts (i.e. voluntary, but enforceable, agreements). Property the Federal Coastal Zone Management Act and the State Shorelines Management Act are Property Rules Owners, backed by courts, Control Tidelands, oysters, coastal land, watercraft Nature Trusts & Liens ESA Prohibitions, Riparian Buffers rules are the bundles of privileges and re- strictions that per- Use Regulation tain to the use of any F&W Regs, Fish Quotas Water Rights property. In modem urban and suburban coastal systems occurs in a complex web of social customs, and rules promulgated by local and regional governments, special agencies and districts (Ports, water districts, watershed councils), and State and Federal governments. Water quality regulations under the Federal Clean Water Act, for example, are implemented by a State permit process that relies on self-reporting of pollution events. In Washington State Zoning State/Local Land Use Control Lot Sizes, Set-backs, Building implemented by local governments.

A typology of coastal ecosystem resource regulations. on construction of buildings under city or county land use zoning regulations, restrictions on uses that disturb or endanger neighbors under nuisance law, restrictions on discharge of polluted water by regulations under the Clean Water Act, and restrictions on building exterior appearance or landscaping or vehicle parking under privately agreed codes, covenants and restrictions (CCRs). Many of these property rules affect land ownership near the estuaries and coastal ocean areas in the PNCERS region. For example, owners and leaseholders of tidelands in Washington coastal estuaries frequently exercise their rights to raise oysters or to dig for clams. They, in turn, depend on the enforcement of restrictions on water pollutant discharges that reduce the whole- someness of, or spread disease among shellfish. Zoning of land along mudflats for development of large-scale tourist facilities, for example, might pose a threat to water quality and shellfish growers. So, water quality regulations could help protect and enforce property rights of shellfish growers while weakening and restricting the rights of some shoreline land owners. Some activities are found to be directly limited through specific formal government rules. For example, channel dredging and navigation is regulated by the Army Corps of Engi- neers and salmon fishing is controlled by State and tribal regulations. But the bulk of human activity affecting the of Washington State's eighteen departments (Figure 9.1). Each department is responsible for specific aspects of the coastal ecosystem (water quality, State land use, navigation, human health risks, fish conservation, endangered species protection, etc.). The Department of Natural Resources, for example, leases tidelands to oyster growers, and the Department of Ecology implements water quality regulations. The bewildering array of customary, legislative, contractual and cooperative controls on use of the bays, tidelands and nearshore lands can be understood through the use of a typology. Our typology or resource regulation (Figure 9.2) includes property rules, resource use regulations, resource use permits, and zoning rules. Property rules include all those customary rights and common law responsibilities and limitations pertaining to personal and business property. This includes nuisance law, liability law, and commercial or contract law. Resource use regulations comprise restrictions on private use of public or common resources; e.g. fishing regulations, water rights, and regulated closures of public lands and water to certain uses. Resource use permitting is distinguished from Use Regulation as it involves issuing a general permit to engage in a specific activity: a water pollution emissions permit, for example. Zoning is a restriction of private leased property that limits the location and/or size of structures. Not all regulations fall under just one category. Re- striction of land for wildlife habitat under nature trusts or INSTITUTIONAL MAPPING 55 PNCERS 1999 ANNUAL REPORT liens represents a hybrid of property rules and zoning. i.e. reservation of private land for a public purpose under contract. Regulation of minimum stream flows to achieve water quality (usually temperature) standards is a hybrid of water use regulation and water quality permitting. And restrictions on use of riparian or shore land to protect public wildlife or fish habitat is a hybrid of resource use regulation and property rules. This typology will facilitate further discussion and research on ecosystem management in the coastal estuaries. To implement an ecosystem approach to managing coastal areas requires creative changes in the web of interweaving and overlapping authorities and rules. Much of the management activity is generated by government agencies. How ever, coordination and cooperation among government agencies, local governments and industries can be facilitated by non-governmental organizations such as the Pacific Oyster Growers Association and the Willapa Alliance. Special multiparty coordinating groups frequently form to deal with specific problems. The Willapa Bay Water Resources Coordinating Council is a Pacific County board appointed by the County Board of Commissioners that works to coordinate the community interests in multiple uses of Willapa Bay. The )FW WS Citizen Groups Pacific County Noxious Weed Control Board 'aier Bay ribe Pacific Oyster ;rowers Assoc. 4 council oversees the drafting and implementation of the Willapa Bay Water Quality Plan and other similar documents. The Pacific County Noxious Weed Control Board oversees the noxious weed program for Pacific County interests. The Board targets weeds that are non-native, invasive and detrimental to the economy or environment. A prime example is the exotic cordgrass Spartina alterniflora, which has invaded mudflats and eelgrass beds used by the Oyster industry and which are potentially important to juvenile salmon.

Yet others have mutual interests to promote: Pacific Coast Oyster Growers Association, Willapa Alliance, Washington Department of Natural Resources (leases state tidelands). Institutional mapping provides a comprehensive, descriptive means of viewing and understanding the multitude of regulatory and other relationships between industries, communities, interest groups, and agencies. It also clarifies the link between legislative/judicial rules and management authorities that give these relationships staying power. Implementing management measures that protect or enhance the natural ecosystems of Pacific Northwest estuaries requires the mobilization and coordination of decision making through the webs of organizations and institutions depicted in these maps Integration & Interaction By design, the Institutional Mapping and Socio-economics Baseline Project promotes integration and research interactions. Knowledge of organizations, laws, institutions, and decision processes that affect the PNCERS estuaries and regional demographic and economic trends of areas surrounding the estuaries serves as a foundation for the PNCERS social frame research. Our baseline understanding of these factors shaped the development of the coastal resident survey questionnaire (Rebecca Johnson) and the coastal practitioner survey (Tom Leschine). This knowledge will continue to be employed, especially in subsequent years when specific management questions and issues are addressed.

Third, residents frequently note natural resources as the reason for locating and staying in their communities. Finally, residents have extremely strong opinions about threats to ecosystem health and the design and implementation of natural resource management strategies. It will be interesting to see whether or not the final responses will offer similar conclusions when compared and contrasted with the results of past surveys. While the pre-test only involved a small sample, the results are useful in foreshadowing what may come out of this re- search effort in the future. The responses to a subset of questions are 22 males and 6 females. The average age of the respondents is 58. Forty six percent of the respondents are retired and only 28 percent of the respondents have a college diploma or higher level of education. 71 percent of the respondents live in coastal communities year round, with an av- erage length of resi- dence of 24 years.

The pre-test sample includes 28 individuals, respondents were asked to rank the importance of different community attributes in affecting specific choices. Table 10.1 displays the responses to two questions on how important community attributes are in choosing to live in and move to a coastal community.- Please note that the scores for these two questions are not comparable directly because of a difference in the wording of the questions.

Twenty one percent of the respondents indicated membership in an environmental or conservation organization and/or membership in a sporting or recreation group. Several questions in the first section of the survey address issues related to coastal communities. These questions are included to help us better understand the role of the coastal ecosystem in these communities and attitudes about ongoing demographic and economic changes in these communities. It is interesting to compare the responses to questions where portant. The scores for the "moving" choice are based on responses to a question that asked respondents to list the three most important community character- istics that influenced their choice to move to the coastal community. 31 Here, scores were de- 17 rived by assigning 4 27 4 33 3 6 weights of 5, 4, and 3 to the top choices listed by each respondent and then summing over the sample. When asked 85 29 83 75 72 11 about why they choose to live in a coastal com- 15 munity, high scores 6 69 45 34 were given by respondents to attributes such as little traffic conges- 64 Notes: 1 Score is the sum of rankings of importance on a scale of 1 to 5.

However, when asked why they moved to that commu- nity in the first place, attributes such as job opportunities, being near family and friends, having fewer people (low popu- lation density), being near the ocean, and climate/weather received the highest scores. Interestingly, many respondents noted ongoing changes in these community attributes. Over fifty percent of the sample believe that the cost of living, job opportunities, crime rate, and housing costs are getting worse in their community, while 30 percent feel health care and public services are improving in their community. Numerous respondents stated that increases in the cost of living and reductions in job opportunities are so great that they are considering moving away from their coastal community. PERCEPTIONS, ATTITUDES, AND VALUES 59 PNCERS 1999 ANNUAL REPORT The second section of the survey addresses recreation activities. Natural resource-based or outdoor recreation is an important factor in these communities for several reasons. First, the local economies rely on such recreation opportunities in promoting tourism. Second, recreation opportunities are an important source of value to the residents of and visitors to these areas. As a result, information on recreation behavior can be used to inform decisions regarding natural resource management. We included several questions on recreation and erosion, and decline in fish habitat are considered the greatest threats based on this ranking. When asked who should be most influential in making natural resource management decisions, 40 percent of respondents noted existing partnerships between government and citizens. 30 percent believed county governments should be most influential. Only one respondent believed the federal government should be most influential, and only two felt that role should be assumed by the state government. These responses are consisto understand better if, how, and where residents recreate tent with other regional survey findings concerning who both regionally and in their commushould be responsible for mannities. Overall, participation rates agement (Bell, 1999). These Table 10.2. Importance of potential threats to the varied considerably by activity: pro-local sentiments were also estuarine environment.

Widespread trust was placed in ming (11%), surfing (4%), and kayaking (0%). Responses to questions on local recreation activities suggest some interesting trends in recreation near the PNCERS estuaries.

The section begins by asking re- scale of 1 to 10. Each respondent was asked to rank all of the ecological threats. time. The third section of the survey focuses on the health of the estuarine environment. In this section, we ask respondents for their opinion of threats to the local estuarine environment. Understanding public perceptions can help identify areas where outreach efforts may be targeted. In addition, public opinions of threats and management programs can be important because support for natural resource management policies from the community can affect the performance of those policies. Table 10.2 shows one ranking of ecological threats, where the ranking is again based on scores that reflect the sum of the (1 to 5 scale) responses indicating importance by ecological threat.

After presenting respondents with detailed historical information on coastal chinook and coho salmon stocks, the survey then asks respondents to indicate their support or lack of support for a referendum that would establish a program that would protect coastal coho salmon runs. Respondents were asked to reveal their votes (yes or no) for two different proposed referendum programs, and the household costs (annual tax amount) of the programs were varied randomly over the surveys. 25 percent of the respon- dents voted yes, demonstrating support for both of the programs; while 75 percent responded no to both of the programs. This series of questions proved to be the most confusing for respondents and has been revised substantially for PNCERS 1999 ANNUAL REPORT the final questionnaire Because of these difficulties, we will not elaborate further on the pre-test responses. the survey, as the survey questions focus on a range of Design of Final Coastal Resident Survey Questionnaire During the fall of 1999, the coastal resident survey questionnaire was also circulated for further review by researchers with survey expertise. As noted previously, comments from many of the PNCERS researchers and partners were instrumental in revising early drafts. In general, we received positive feedback on the survey questionnaire from the 28 respondents who returned their questionnaires. However, the responses themselves suggested some sections of the survey were unclear. External reviewers made useful suggestions regarding the wording, design, and length of the final survey questionnaire For more details on social frame integration refer to Social Frame Interactions and Integration, page 69. Based on the pre-test responses and external reviews of the coastal resident questionnaire by individuals with survey expertise, Rebecca Johnson, Kathleen Bell, and Daniel Huppert worked as a group to finalize the coastal resident survey questionnaire The final questionnaire attempts to meet the protocol designated by the NOAA Panel on contingent valuation in 1993 (Federal Register, 1993) and reproduced in Portney (1994) and strongly reflects the insights of Mitchell and Carson (1989) regarding the use of surveys to value public goods. In February, 2000, 5,000 survey questionnaires were mailed to residents living within 30 miles of the different estuaries.

(Knowledge Diffusion Model) Concerted effort at "science communication" is required (or desirable) for policy-relevant scientific results to have the influence that "they should". (Orchestrated Science Communication Model) Scientific information enters policy arenas in "pointcounterpoint" fashion, introduced by position advocates in policy disputes. "Policy brokers" may act to filter or validate information that ultimately forms the basis for policies, or that drives policy change. ("Advocacy Coalition Framework" approach; developed by P.

The Grays Harbor Estuary Management Task Force is the oldest estuary management organization in the region and one of the oldest such organizations in the United States, having been established in 1975. The Chehalis Basin Partnership (CBP) is much newer, now in just its third year of existence. Specific questions being addressed by research in this area include: What is the capacity of the region's management institutions to incorporate PNCERS-like research results in ways that lead to more integrated management approaches and improve "sustainability" of the resource The Grays Harbor Estuary Management Task Force was founded originally to help implement and streamline a permit process that was becoming ever more complex and, from the standpoint of some local constituencies, burdensome. The introduction of shoreline permitting under Washington State's Shoreline Management Act in the 1970s had brought to the ENVIRONMENTAL AND ECOSYSTEM MANAGEMENT 63 PNCERS 1999 ANNUAL REPORT fore increasing conflict between the needs of environmental protection and the needs of economic development in the Grays Harbor region. One dispute, whether or not wetlands should be filled for the construction of a facility to build offshore oil platforms, drew national attention to Grays Harbor. Out of this dispute came the creation of the Grays Harbor National Wildlife Refuge, one of the most important migratory shorebird feeding and resting areas on the West Coast. The Task Force produced the Grays Harbor Estuary Management Plan (GHEMP), which has been adopted by the local governments into their Shoreline Master Plans and incorporated into the Washington State Coastal Zone Management Plan. Today, the agenda of the Task Force has broadened somewhat, and the plan is undergoing one of its periodic reviews. But GHEMP's primary focus remains on permitting issues. By contrast, the CBP came into existence in 1998 as a means for local governments to exert more control over environmental management in the basin. Subsequent to its formation, it became the "Water Resource Inventory Area" (WRIA) lead entity for the Chehalis River Basin, part of a new state- Among questions both are facing are: how much to broaden or narrow the scope of their endeavors, how much to invest in coordination or collaboration with other local and regional entities and state and federal authorities, and how much to invest in monitoring or other efforts to understand the status of resources and resource threats in the region. Moreover, each organization's purview encompasses a geographic area in which human activity has the potential to directly affect the management efforts of the other (the Chehalis River is the dominant freshwater inflow to Grays Harbor). Thus each faces in theory at least the question of whether and how it should try to "integrate" its mission with that of the other (and, more generally, other entities with similar geographically or functionally overlapping missions). Our research strategy was first to review relevant literatures to develop an "ideal" model of integrative resource management against which to compare each of the two entities. We examined literatures on a) estuarine, watershed and coastal management, b) "ecosystem management" (predominantly aimed at terrestrial, especially forested, ecosystems), and c) "systems" and organizational theory. As an example of the kinds of organizational characteristics that can be gleaned from such a review, the literature on "organizational learning" suggests a hierarchy of characteristics that can be ap- wide system of administrative areas established to promote integrated watershed management. As the WRIA lead entity, it is responsible for taking an inventory of scientific data plied to gauging an organization's ability to "learn."

In this role, the CBP's most immediate task is Perceptions of the Flow ofinformation Between Science and to evaluate proposed restoration projects in the basin for their Management suitability for funding under the state's Salmon Restoration This research examines how environmental managers and Enhancement Fund.

These include examination of environmental planning management organizations affecting Grays Harbor, Washington. the coho stocks of the outer coast, which have since been listed as 'threatened'. We examined both organizations' current and recent past activities. For GHEMP, this meant we focused on the most recent five- year review of GHEMP (as mandated by its charter) and the process of defining adjustments to the GHEMP in light of the review. For CBP, this meant we examined the process of putting the basic CBP organization into place and defining what its mission would be. Interviews with organizational representatives, documentary review and attendance at meetings of the two entities revealed that they have or are now facing somewhat similar organizational issues. 64 Organization shows ability to recognize: Need for information not currently on hand (and can deploy resources to collect same) Management objectives not being met and approach must be modified accordingly (e.g. can design, implement and utilize monitoring to adjust operations) Objectives not being met and objectives must be changed (e.g., can shift to ecosystem-based, rather than single-species management) Need to plan for, and adapt and respond to: uncertainty (environmental, or regarding decision consequences) fallibility (the possibility of failing to carry out tasks as intended) Need for fundamentally different organizational arrangements (either to achieve different purpose or to achieve same purpose in new ways, as for example, through collaboration with other organizations) ENVIRONMENTAL AND ECOSYSTEM MANAGEMENT PNCERS 1999 ANNUAL REPORT science and management.. Specifically, we are exploring whether or not they perceive barriers that limit the ability of science to inform management decisions, and what steps they believe would improve this information flow. This work in progress seeks generally to understand the environment in which PNCERS research might find application in improving the management of marine and estuarine resources in the PNCERS study region. This project is expected to result in a masters thesis by UW School of Marine Affairs student Michelle Pico. Our approach is to conduct a mail survey, which to date has been distributed to more than 300 environmental researchers and environmental managers in Washington (n=125) and Oregon (n=178) (refer to Table 11.2). The survey examines: How each of these two groups perceives its own vs. other group's "professional culture" and reward system Where difference is perceived, the extent to which it is seen to help or hinder the cause of science relevancy to, and use in, resource management decisions The effort that each group thinks is warranted to improve researcher - manager communication so that management-relevant research will be conducted and used in management Most responses are elicited via closed-form questions. The survey also asks for the respondent's advice on how best to improve the flow of information between scientists and managers, however. Both researchers and managers are asked to identify the specific estuaries where they do their work or with which they are most fa- Table 11.2.

ENVIRONMENTAL AND ECOSYSTEM MANAGEMENT 65 PNCERS 1999 ANNUAL REPORT Results & Discussion Capacity Assessment of Regional Environmental Planning and Management Institutions Our use of a systems-theoretic framework, coupled with an ecosystem management perspective, enabled us to key on a few basic principles of organization and organizational conduct for our analysis. We looked for: 1 evidence of "feedback and control" (the ability to detect and correct error) as planning and management proceeds, the relationship between problems of concern to the organization and its jurisdictional boundaries and management tools-in-use, the extent of "integration" present, i.e., coordination or collaboration with other entities capable of affecting the same problems both at similar jurisdictional levels (local and county'horizontal' integration) and at higher jurisdictional levels (state and federal' vertical' integration), extent of public involvement, and evidence for "emergent" system properties (extent to which the system exhibits such desirable whole-system characteristics as stability, resilience, adaptabil- ity to environmental change, etc.) Evidence that biodiversity was being preserved or enhanced or that sustainable resource use was resulting from management is an example. Several hypotheses guided our inquiry. Among them, that: Relatively greater incentives exist to plan than to implement (thus rendering completion of the feedback loop to assessment and adjustment relatively difficult). Underlying cause: Fiscal costs of (centralized) planning are much less than organizational costs of (decentralized) implementation (and in fact can be seen as an organizational "good"). Relatively little attention beyond regulatory compliance is given to horizontal and vertical integration compared to attention to own mission; Underlying cause: Costs of integration are perceived to outweigh benefits, or costs of "going own way" perceived as less than costs of integration. 66 ENVIRONMENTAL AND ECOSYSTEM MANAGEMENT Incentives for public participation in estuarine resource management are relatively low, with result that local management organizations in turn have low incentive to view problems from the "multiple perspectives" that form the foundation of ecosystem-based management. Underlying cause: A perceptual gulf exists between environmental managers and ordinary citizens, who interpret managers' claims that "environmental" problems exist as further evidence of continued economic and community decline. Our assessment of the operations of the two groups largely confirms these hypotheses, particularly for the GREMP task force. For the CBP, which is very new, our conclusions must necessarily be more tentative. The CBP, with a specific habitat protection and restoration mandate, and state funding for at least some of the projects it recommends, appears more likely to make good use of appropriately targeted scientific information than the GHEMP task force at this point. Currently lacking buy-in from surrounding communities on several aspects of its proposed plan revision, it appears that the GREMP task force would value new scientific information pointing to resource sensitivity to human-induced harm less than it would value information that would help facilitate and expedite permit review, and hence "buy in" from local communities. GREMP has never conducted environmental monitoring nor has it sponsored directed study of the Grays Harbor environment. The CBP would presumably welcome information that helped it develop habitat restoration and protection spending priorities, but might find some types of information more conducive to conflict than to cooperation. The latter category potentially includes information suggesting that local habitat restoration efforts are not likely to be successful, or that habitat restoration and protection opportunities outside the Chehalis Basin are superior to those that lie within it. The CBP has a specific mandate to assemble scientific information relevant to its task, something GHEMP's overseers have never had. The CBP appears to be open to considerable variation in how it approaches its basic mission of focusing on the Chehalis Basin. Possibilities appear even to include some that could extend the partnership to embrace economic development initiatives. As such, CBP has the character of a governmental enterprise whose way of doing business has been influenced by the "reinventing government" movement championed by Vice President Al Gore and others at the federal level. For example, some CBP representatives take an entrepreneurial stance on the organization's budget, actively seeking ways to build a bigger funding base than the organization has at present. By contrast, GHEMP task force members tend to see the budget as setting the limits on the aspira- PNCERS 1999 ANNUAL REPORT tions that the organization can reasonably afford to have. Neither organization has a strong citizen participation component to validate its endeavors at this point, and representatives of each view the lack of broader participation from the surrounding communities as a problem. Neither sees partnership with the other, even if limited to defining an agenda of problems of mutual interest, as offering very clear benefits. While CBP could be accused of exhibiting youthful enthusiasm as yet untempered by the lessons of advancing age, GHEMP has suffered its share of disappointments over its long life. Chief among these is a long-standing desire to work more closely with state and federal entities whose jurisdictions overlap with GHEMP's permit authority under the state's Shoreline Management Act. The ability to influence permit-review at all levels, so that it is more compatible with the local interest in pursuing economic development, was a primary motivation for forming GHEMP in the first place, and it has gone largely unrealized. The reason appears to be lack of interest (and perhaps authority) by higher level entities, upon whom GHEMP has been able to exert little influence. Neither these benefits of cooperation nor other offsetting benefits have materialized, which may largely explain the modest level of its accomplishments over the past quarter century. We speculate that the CBP will similarly have realize benefits of an economic nature from its efforts at enhancing the Chehalis Basin (e.g., salmon stock recovery that stimulates segments of the local economy that derive income from recreational or commercial fishing or tourism) if it is to sustain its current levels of enthusiasm. their counterparts in Washington. This may reflect differences in how the two states organize their coastal and estuarine programs, a question we plan to pursue through examination of the results of the "institutional mapping" project described elsewhere in this report. Integration & Interaction The two projects reported on here both contribute to our understanding of how PNCERS research in the natural and so- cial sciences can contribute to improved management of coastal and estuarine ecosystems. The proposed years 4 and 5 project to which they lead involves direct collaboration with PNCERS natural science investigators (possibly Julia Parrish, Steve Rurnrill, Ron Thom, and related post-docs). The Environmental and Ecosystem Management component of the PNCERS Social Frame Studies is highly integrated with other aspects of the Social Frame work, addressing as it does the management implications of improved understanding of natural and socio-economic resource systems. The coastal practioners survey project, when completed, is expected to be highly relevant to the outreach activities of the PNCERS project management team. Active collaboration with them on how to put into practice the ideas generated by the survey on strengthening the management-research linkage is anticipated.

Among interesting preliminary findings are that the distinction between who is a researcher and who is a manager is not as clear as one might expect. Many, if not most, respondents feel their jobs require them to do a little of both. Only about 25% of respondents classify themselves as having purely management or purely research jobs. Another preliminary general finding concerning this group is that relatively few individuals work exclusively or even a majority of the time on estuarine or coastal problems (refer to Table 11.2). Oregon researchers and managers appear somewhat more likely to focus predominantly on estuarine or coastal issues than do Publications: A.K. Bennett. 2000.

PNCERS 1999 ANNUAL REPORT Social Frame Interactions and Integration Kathleen Bell Introduction tion of this type will continue to gain prominence in the final years of the PNCERS research project. As the social research program has evolved, two types of integration have been emphasized. The first type involves the integration of the different social science research projects, while the second type reflects the integration of social and natural science research projects. Although different in some aspects, both types of integration serve the same goal: understanding how humans use, value, and impact the coastal ecosystems and marine resources of the Pacific Northwest and, in turn, how management affects the status of the Pacific Northwest coastal ecosystems and marine resources. Much of the social research stems from the following PNCERS research objectives: developing predictive models that support adaptive management of living marine resource and/or human use, and; evaluating the appropriateness of management practices and programs that affect coastal ecosystems and living marine resources. Recognizing the ultimate goals of supporting and improving management processes, the social frame has been carefully designed to inform a final set of projects tailored to meet these specific research objectives. There are currently four projects falling under the Social Frame: Institutional Mapping and Socio-economic Baseline (Daniel Huppert); Public Perceptions, Attitudes, and Values (Rebecca Johnson), Environmental and Ecosystem Management (Tom Leschine), and Integrated Ecological-Economic Modeling (Kathleen Bell). Together, these projects address the human dimension of the PNCERS project, weaving together knowledge of economic and demographic trends, public attitudes, governance, human behavior, and economic values. Proposals for future years call for narrowing the research to two projects, one on management and one on the use and value of the PNCERS coastal ecosystems and marine resources. These two projects will rely heavily on the findings of the previous social frame projects, building on the foundation established during years 1 through 3. Integration with ongoing natural science projects is also a priority of the social frame. Several of the social science projects have been designed specifically to incorporate aspects of the marine resources and coastal ecosystems under study and have developed with considerable input from the natural science investigators. It is likely that active integra- Results and Discussion The Institutional Mapping and Socio-economic Baseline Project (Daniel Huppert) established a baseline understanding of the organizations, laws, institutions, and decision pro- cesses that affect the PNCERS estuaries and the regional demographic and economic trends of counties surrounding these estuaries. When examining the latter, attention was given to the connections between estuarine natural resources and these trends. The Socio-economic Baseline information influenced the development of the coastal resident survey questionnaire (Public Perceptions, Attitudes, and Values Project; Rebecca Johnson). Several questions on the coastal resident survey seek the attitudes of respondents concerning economic and demographic trends that are noted in the socio- economic baseline research. In addition, the institutional mapping research fed directly into the development of the coastal practitioner survey (Environmental and Ecosystem Management, Tom Leschine). The sample population of the coastal practitioner survey was identified using a database of organizations constructed as part of the institutional mapping research. The institutional mapping research is also likely to further supplement both the Environmental Ecosystem Management Project and the Integrated Ecological Economic Modeling Project in the future, as these projects scrutinize specific management objectives and interactions between the ecological and economic systems. The Public Perceptions, Attitudes, and Values Project (Rebecca Johnson) centers on the coastal resident survey that seeks the opinions of residents on characteristics of their community, outdoor or natural resource-based recreation, threats to and management of the local natural environment, and preservation of coastal salmon stocks. The design of the survey strongly reflects the goal of integration. The survey and its analytical framework were developed by the social frame researchers as a group. This joint effort ensured that numerous research interests would be met and that the de- sign of the survey would be appropriate given our understanding of the local communities, government, and other environmental planning organizations. Two direct interactions with other social science research projects emerged as significant. First, a subset of questions on the coastal resident survey also appear on the coastal practitioner survey (Environmental and Ecosystem Management Project; Tom Leschine). This duplication will allow for comparison of the SOCIAL FRAME INTERACTIONS AND INTEGRATION 69 PNCERS 1999 ANNUAL REPORT responses of coastal residents and managers. Second, one question on the coastal resident survey related to characteristics of residences and/or location is designed to parallel the property value modeling (Integrated Ecological-Economic Modeling Project; Kathleen Bell) research. Responses to these questions will act as a supplement to the findings of the empirical model. Finally, the coastal resident questionnaire direct collaboration with PNCERS natural science investigators (possibly Julia Parrish, Steve Rumrill, Ron Thom, Curtis Roegner, and Libby Loggerwell). The Integrated Ecological-Economic Modeling Project (Kathleen Bell) focuses on the feedbacks between ecological and economic systems. Similar to the case of the Envibroadly integrates with many of the PNCERS natural sci- ronmental and Ecosystem Management Project, this research ence projects.

This year's Eat & Learn Seminar Series, like last year, provided a lively and informal forum for PNCERS researchers, collaborators, and others to both learn about ongoing research and participate in shaping its direction. This years' series, which took place Winter Quarter, 2000 at the University of Washington, was even better attended than last year, attracting people from the nearby NMFS lab, as well as faculty and students from both the fisheries and zoology departments. Seminar speakers included those PIs who did not get a chance to present last year, PNCERS' three post-doctoral students, a graduate student and a member of the Program Management Team (Table M.1.). One of the most important functions of the seminar series is to foster collaboration among researchers and integration of research projects. Presentations and discussions this year emphasized collaborative work that was initiated or built on during the January 20-21 All-Hands meeting. For example, Julia Parrish presented plans to work with EPA collaborators Ted DeWitt and Pete Eldridge on including seabirds in estuarine food web models. Using stable isotope analyses, they will distinguish the percent of the diet of the Yaquina Bay common murre colony that comes from the nearshore versus the estuarine systems. Gordon Swartzman focused his seminar on the collaborative aspects of his research on fish and plankton distribution. Most significantly, he and Curtis Roegner, with help from David Armstrong and Barbara Hickey, are working together on the RESEARCH PROGRAM MANAGEMENT 71 PNCERS 1999 ANNUAL REPORT question of how larvae travel from ocean feeding areas to estuarine breeding grounds without getting swept away in southwest currents. Several hypotheses have been put forward, including avoidance of currents through diurnal vertical migration. Elizabeth Logerwell, PNCERS' most recently hired postdoctoral fellow, explained how her previous work with modeling California current sardine survival could be applied to survival analyses of Pacific Northwest salmon smolts, and how it could integrate with nearshore dynamics discussed at the all-hands meeting. Metadatabase The metadatabase currently contains information on approximately 70 different databases relating mainly to oceanogra- phy, meteorology and fisheries (Table M.2). Fifty of these records were added since last year. Plans are to provide an equal amount of information on socioeconomic and biological databases. PNCERS researchers draw on the metadatabase for a variety of purposes, from plotting sea surface temperature for a particular place and time, to assessing what kinds of GIS information is available for Willapa Bay. Like these researchers, database managers respond with great enthusiasm to the immi- Table M.1.

Parrish, and Elizabeth A. Logerwell Introduction (Figure 1, page ix). Whereas the foundation of PNCERS has always been based on the independent research projects, two The third annual PNCERS All-Hands Meeting was held at the University of Washington's Center for Urban Horticulture on January 20 and 21, 2000. Thirty-three people attended, including all PNCERS PT's (except Ray Hilborn, in New Zealand), postdoctoral research associates, research staff, graduate students; several collaborating researchers; as well as PNCERS and Coastal Ocean Program (COP) managers (Table A.1). The meeting was structured to foster collaboration among researchers and integration of research projects, in the directions suggested by the Collaborations Diagram major themes have been emerging from current PNCERS research: 1) the broad scale role and consequences of physical forcing, and 2) the more local interplay between human activities and environmental change. The former defines much of the work in the nearshore environment, as physical forcing and dynamic variability in oceanographic and atmospheric forcing factors exert a large influence on trophic structure, ecosystem function, and ecosystem production of goods and services in the nearshore. The latter defines much of the work in the estuarine environment, as human activities and Table A.1. Attendees at the PNCERS All-Hands Meeting, January 20-21, 2000.

The allhands meeting concentrated on defining areas of collaboration within PNCERS as well as among collaborating prograins, with specific reference to nearshore and estuarine environments, focusing on physical forcing in the former and human activities in the latter. The Estuarine Group The Estuarine group's discussion centered around two main areas: potential new projects that could integrate ongoing research in useful ways and The meeting started with 14 short presentations on the cur- rent status and most recent results from each of the 12 ideas for how to "tell a story" about Pacific North- PNCERS research projects, as well as related and collaborative research projects (Table A.2). These summary presentations generated enthusiastic questions and discussions on potential avenues for collaboration among projects. Animated discussions continued during breaks and over lunch. west estuaries based on current and projected PNCERS data. Break-out group sessions on the afternoon of the first day and all day on the second day centered on the major themes outlined above, with one group focused on physical forcing in the nearshore system and the other on human impacts and interactions in the estuarine system. Researchers were not confined to one group, so that those involved in research in both the nearshore and estuarine systems could contribute to both discussions. Emphasis in both areas was on how useful these projects and/ or stories would be to continued research, ecosystem management, and outreach and education. GIS Development There was overwhelming consensus on the need to develop a Geographic Information System that would integrate and facilitate analysis and presentation of diverse sets of estuarine-related data, such as current as well as historical information on estuarine habitat, biota, human development, and land use. This effort might include meso- to fine-scale map- Table A.2. PNCERS All-Hands Meeting Schedule, Jan 20-21, 2000.

Ecological-economic valuation The group agreed to pursue "valuation" of the estuarine ecosystem, relying not only on economic data but also on biological indicators such as the Index of Biotic Integrity, and normative social values reflected in the coastal residents and managers surveys which were distributed earlier this year. It was determined that the process of valuation would work most effectively in conjunction with the development of an estuarine ecological-economic model. Ocean Influence The estuarine group saw the need for a more sophisticated way of understanding and visualizing the impact of ocean currents and circulation on estuarine functions. They agreed to incorporate the growing understanding of circulation and water properties in the assessment of spatial and temporal variations in habitat and biota. In addition to these major proposed projects, several new data collection efforts were identified that are needed to fill existing data gaps: chlorophyll measurements, stable isotope (carbon and nitrogen) analysis of estuarine food webs, and nitrogen limitation for eelgrass and diatoms. Integrating for Outreach Discussion on integrating research for outreach purposes focused on choosing an indicator, or set of indicators that could become the focal point(s) for the Pacific Northwest estuarine "story". Ideas for potential indicators were: oyster production, salmon, marine birds, ghost shrimp, eelgrass, estuarine habitat, land use, water quality, and/or nutrient propagation and tideflat depletion. Oyster production was the most popular indicator suggestion, as it has the potential to integrate most PNCERS research, is economically relevant, links to water quality, and would be a factor involved in restoration projects, among other things. Ideas for broad thematic story "plots" were: ecosystem decline (reflected in, e.g, an oyster condition index, habitat change, and/or eelgrass change), human behavior changes due to oceanographic or climatic effects, and/or the overlay of human and biological induced variability on the "original conditions" of physical fluctuations. It was suggested that there should be two or more contrasting stories, representing estuaries that span the PNCERS region, and that these stories should highlight that complexity of human-ecosystem interactions. These were all preliminary ideas for outreach, and it was also pointed out that we don't yet know enough to tell a definitive story. The Nearshore Group The Nearshore group focused on defining avenues of collaboration between existing PNCERS projects (Swartzman, Parrish, Hilborn), PNCERS postdoctoral research (Logerwell, Roegner), GLOBEC-NEP research (Brodeur, Swartzman, Hickey), NMFS researchers (Brodeur, Wainwright) and RSA() and other UW research (Mantua, Francis, Fields). The possibility of collaboration between PNCERS and the various research programs being conducted by Ric Brodeur and his colleagues at NMFS was discussed extensively. Three ongoing field efforts to survey juvenile salmon, their prey, their predators and other habitat information were described by Brodeur. The projects are funded by GLOBEC, BPA (Bonneville Power Administration) and EPA. The BPA project is focussed on the Columbia River plume and the EPA project is targeting the very nearshore environment. It seemed appropriate for Libby Logerwell to participate in any of these research cruises, and discussions along that line were initiated and continued during the weeks following the meeting. Several interesting lines of integration were discussed by the participating scientists. Regarding Hilborn and Magnusson's project on salmon survival, as assessed with coded wire tag data (CWT), integration of large scale retrospective data on upwelling and winds into his general linear model was mentioned. Collaboration with Parrish on bird predator data was also discussed. Another collaboration seriously considered was one between Parrish, Logerwell and scientists at the Newport EPA (Pete Eldridge and Ted DeWitt). The goal would be to conduct stable isotope analyses of seabird tissues to assess the relative foraging activity occurring in estuarine and nearshore habitats. This information would be required for Logerwell to construct bioenergetic models of salmon growth and survival in both habitats. Efforts on the part of NMFS, PNCERS, and other UW scientists (particularly John Field, a student of Bob Francis, and Nate Mantua, a research scientist at JISAO) to construct an ECOPATH model of the northern California Current were discussed. A follow-up meeting to cross-foster modelling efforts among the NMFS, UW, and PNCERS scientists has been set for midApril, 2000. ALL-HANDS MEETING 77
