OR: U.S. Department of Agriculture, Forest Service, Pacific Northwest Research Station. 3 vol. (Quigley,
Thomas M., tech. ed.; Interior Columbia Basin Ecosystem Management Project: scientific assessment).
We defined habitat requirements (source habitats) and assessed trends in these habitats for 91 species of terrestrial vertebrates on 58 million ha (145 million acres) of public and private lands within the interior Columbia
basin (hereafter referred to as the basin). We also summarized knowledge about species-road relations for each
species and mapped source habitats in relation to road densities for four species of terrestrial carnivores. Our
assessment was conducted as part of the Interior Columbia Basin Ecosystem Management Project (ICBEMP),
a multiresource, multidisciplinary effort by the USDA Forest Service (FS) and the USDI Bureau of Land
Management (BLM) to develop an ecosystem-based strategy for managing FS and BLM lands within the basin.
Our assessment was designed to provide technical support for the ICBEMP and was done in five steps. First, we
identified species of terrestrial vertebrates for which there was ongoing concern about population or habitat status
(species of focus), and for which habitats could be estimated reliably by using a large mapping unit (pixel size) of
100 ha (247 acres) and broad-scale methods of spatial analysis. Second, we evaluated change in source habitats
from early European settlement (historical, circa 1850 to 1890) to current (circa 1985 to 1995) conditions for each
species and for hierarchically nested groups of species and families of groups at the spatial scales of the watershed (5th hydrologic unit code [HUC]), subbasin (4th HUC), ecological reporting unit, and basin. Third, we summarized the effects of roads and road-associated factors on populations and habitats for each of the 91 species and
described the results in relation to broad-scale patterns of road density. Fourth, we mapped classes of the current
abundance of source habitats for four species of terrestrial carnivores in relation to classes of road density across
the 164 subbasins and used the maps to identify areas having high potential to support persistent populations. And
fifth, we used our results, along with results from other studies, to describe broad-scale implications for managing
habitats deemed to have undergone long-term decline and for managing species negatively affected by roads or
road-associated factors.
Our results indicated that habitats for species, groups, and families associated with old-forest structural stages,
with native grasslands, or with native shrublands have undergone strong, widespread decline. Implications of
these results for managing old-forest structural stages include consideration of (1) conservation of habitats in subbasins and watersheds where decline in old forests has been strongest; (2) silvicultural manipulations of mid-seral
forests to accelerate development of late-seral stages; and (3) long-term silvicultural manipulations and long-term
accommodation of fire and other disturbance regimes in all forested structural stages to hasten development and
improvement in the amount, quality, and distribution of old-forest stages. Implications of our results for managing
rangelands include the potential to (1) conserve native grasslands and shrublands that have not undergone largescale reduction in composition of native plants; (2) control or eradicate exotic plants on native grasslands and
shrublands where invasion potential or spread of exotics is highest; and (3) restore native plant communities by
using intensive range practices where potential for restoration is highest.
Our analysis also indicated that >70 percent of the 91 species are affected negatively by one or more factors
associated with roads. Moreover, maps of the abundance of source habitats in relation to classes of road density
suggested that road-associated factors hypothetically may reduce the potential to support persistent populations
of terrestrial carnivores in many subbasins. Management implications of our summarized road effects include the
potential to mitigate a diverse set of negative factors associated with roads. Comprehensive mitigation of roadassociated factors would require a substantial reduction in the density of existing roads as well as effective control
of road access in relation to management of livestock, timber, recreation, hunting, trapping, mineral development,
and other human activities.
A major assumption of our work was that validation research will be conducted by agency scientists and
other researchers to corroborate our findings. As a preliminary step in the process of validation, we found
high agreement between trends in source habitats and prior trends in habitat outcomes that were estimated
as part of the habitat outcome analysis for terrestrial species within the basin. Results of our assessment also
were assumed to lead to finer scale evaluations of habitats for some species, groups, or families as part of
implementation procedures. Implementation procedures are necessary to relate our findings to local conditions;
this would enable managers to effectively apply local conservation and restoration practices to support broadscale conservation and restoration strategies that may evolve from our findings.

Foreword
This publication consists of three volumes so that our findings—which consist of hundreds of tables, figures, pages
of text, and supporting citations—could be presented in a manner most usable to resource managers, biologists, and
the public. Volume 1 is designed as an overview of objectives, methods, key results, and management implications.
Volumes 2 and 3 contain increasingly detailed results that support and complement results in volume 1. We believe
that resource managers may find sufficient detail in the generalized results and implications presented in volume 1,
but that management biologists and other users of the results and supporting data will want to refer to all three volumes. Results, management implications, and supporting citations provided in volume 2 are especially important to
consider as part of step-down implementation procedures and related management conducted by field units within
the interior Columbia basin. By contrast, information in volume 1 may be particularly useful in serving broad-scale
planning issues, objectives, and strategies for the interior Columbia basin as a whole. Regardless of application, all
three volumes are intended to function together as a comprehensive assessment of habitat trends and a summary of
other environmental factors affecting terrestrial vertebrates whose population or habitat status is of ongoing concern to resource managers. Data underlying most tables presented in the three volumes also are available at the web
site for the ICBEMP: http://www.icbemp.gov/spatial/metadata/databases.
Preface
The Interior Columbia Basin Ecosystem Management Project was initiated by the Forest Service and the Bureau
of Land Management to respond to several critical issues including, but not limited to, forest and rangeland health,
anadromous fish concerns, terrestrial species viability concerns, and the recent decline in traditional commodity
flows. The charter given to the project was to develop a scientifically sound, ecosystem-based strategy for managing the lands of the Interior Columbia River basin administered by the Forest Service and the Bureau of Land
Management. The Science Integration Team was organized to develop a framework for ecosystem management,
an assessment of the socioeconomic and biophysical systems in the basin, and an evaluation of alternative management strategies. This paper is one in a series of papers developed as background material for the framework,
assessment, or evaluation of alternatives. It provides more detail than was possible to disclose directly in the primary documents.
The Science Integration Team, although organized functionally, worked hard at integrating the approaches,
analyses, and conclusions. It is the collective effort of team members that provides depth and understanding to
the work of the project. The Science Integration Team leadership included deputy team leaders Russell Graham
and Sylvia Arbelbide; landscape ecology—Wendel Hann, Paul Hessburg, and Mark Jensen; aquatic—Jim Sedell,
Kris Lee, Danny Lee, Jack Williams, and Lynn Decker; economic— Richard Haynes, Amy Horne, and Nick Reyna;
social science—Jim Burchfield, Steve McCool, Jon Bumstead, and Stewart Allen; terrestrial—Bruce Marcot,
Kurt Nelson, John Lehmkuhl, Richard Holthausen, Randy Hickenbottom, Marty Raphael, and Michael Wisdom;
spatial analysis—Becky Gravenmier, John Steffenson, and Andy Wilson.

Introduction
This volume is the third in a three-volume publication that defines and assesses trends in source habitats for 91
terrestrial vertebrate species within the interior Columbia River basin (hereafter referred to as “basin”). (See
“Glossary,” this volume, for terms used in this paper.) This assessment was conducted as part of the Interior
Columbia Basin Ecosystem Management Project (ICBEMP), a multiresource, multidisciplinary effort by the
USDA Forest Service (FS) and the USDI Bureau of Land Management (BLM) to develop an ecosystem-based
strategy for managing lands within the basin administered by the FS and BLM. The assessment area extends over
58 million ha (145 million acres) in eastern Washington, eastern Oregon, Idaho, western Montana, and small portions of Nevada, California, Wyoming, and Utah. The purpose of this publication is to provide technical support
to the ICBEMP regarding trends in the areal extent of wildlife habitats in the basin, as well as management implications regarding those trends. Additionally, it can be used to provide a broad-scale view of how wildlife habitats
have changed in the basin since early European settlement and factors that have contributed to those changes.
This publication is focused on source habitats rather than all habitats in which a species is known to occur.
Source habitats are those characteristics of macrovegetation that contribute to stationary or positive population
growth for a species in a specified area and time. Source habitats contribute to source environments, which
represent the composite of all environmental conditions that results in stationary or positive population growth
for a species in a specified area and time. The distinction between source habitats and source environments is
important for understanding our evaluation and its limitations. For example, source habitats for a bird species
during the breeding season would include those characteristics of vegetation that contribute to successful nesting and rearing of young, but would not include nonvegetative factors, such as the effects of pesticides on thinning of eggshells, which also affect production of young. Consequently, we have attempted to identify all
factors that affect population performance of each species as a complement to our explicit analysis of source
habitats. As the foundation for our analysis, we relied on published literature and guidance from species
experts to identify source habitats and additional factors that presumably affect population performance.
The 91 species in our analysis are organized into 40 groups, 37 of which are then organized into 12 families.
Groups are composed of one or more species that share common source habitats, as defined by vegetation cover
types and structural stages. Similar groups also are clustered into families whose source habitats generally fall
into similar terrestrial community groups, a broader classification that includes several cover types. Group size
ranges from 1 to 17 species, and family size ranges from one to nine groups.
Volume 1 describes methods used to select species for analysis, place them in groups and families, estimate
source habitats, and analyze habitat trends. That volume also includes general analyses of source habitat trends at
all three levels—species, group, and family. Volume 1 also identifies causes for the observed trends and ecological processes important for maintaining source habitats as part of the family-level results. Additionally, volume 1
provides a special section on species and groups that are negatively affected by road-related human activities. In
volume 2, we present more detailed results on the analysis of source habitat trends at the group level in support
of the more generalized results presented in volume 1.
The appendices in volume 3 provide additional data and results in support of both volumes 1 and 2. Table 1 provides a complete listing of all vegetation cover type-structural stage combinations identified as source habitats in
the basin for each of the 91 species; other tables summarize source habitats for species and groups by ecological
reporting unit. Also included are a list of species experts who assisted in defining source habitats for our species
of focus, a compilation of common and scientific names, and a glossary of terms used in all three volumes. Thus,
users of our publication can refer to volume 1 for an overview of results and implications, volume 2 for detailed
results that support the overview, and this volume for the most specific results and information in support of both
volumes 1 and 2.

NA = not applicable; groups 38-40 were not assigned to families.
a Calculations of historical and current estimates of extent of source habitats for each group excluded areas outside species ranges
and, by ERU, also excluded those subwatersheds containing no source habitats both historically and currently. See “Assessing
Change in Source Habitats From Historical to Current Conditions for Species and Groups” in the “Methods” section of volume 1 for
further details.
b Species membership in the 40 groups is shown in table 5, volume 1.

-- = negligible or not applicable (values for both historical and current percentage of area <0.004).
a Percentage of area of cover type-structural stage combinations was calculated as the percentage of 1-km2 pixels in an ERU
containing that combination. Absolute change in areal extent of cover type-structural combinations was calculated as (current
percentage of area-historical percentage of area). Relative change was calculated as ([current percentage of area-historical
percentage of area] / historical percentage of area) X 100.
b ERU no. Ecological reporting unit number: 1=Northern Cascades, 2=Southern Cascades, 3=Upper Klamath, 4=Northern Great
Basin, 5=Columbia Plateau, 6=Blue Mountains, 7=Northern Glaciated Mountains, 8=Lower Clark Fork, 9=Upper Clark Fork,
10=Owyhee Uplands, 11=Upper Snake, 12=Snake Headwaters, and 13=Central Idaho Mountains.
c Strcde: structural stage codes are defined in volume 1, table 4.
d Data are displayed in the table to only 2 decimal places; however, 4 decimal places were carried during the actual analysis.
Thus, some estimates of relative change do not match the change that would be calculated from the data displayed in the table.

Glossary
Allopatric—Speciation in which a geographical barrier, such as a mountain range, mediates by preventing gene
flow between populations.
Area of critical environmental concern (ACEC)—An area designated under the authority of the Federal Land
Policy and Management Act of 1976 to protect natural resources, systems, or processes that have more than local
significance or have qualities or circumstances that make them rare, irreplaceable, or vulnerable to adverse
change.
Basin—Defined for this assessment as those portions of the Columbia River basin inside the United States east
of the crest of the Cascade Range and those portions of the Klamath River basin and the Great Basin in Oregon.
Biome—An entire community of living organisms in a single major ecological region.
Broad scale—Coarse-grained level of assessment and analysis but continuous across the basin. Integrated in a
hierarchical approach with mid- and fine-scale assessment.
Candidate species—Plant and animal taxa for which the U.S. Fish and Wildlife Service has enough scientific
information to support proposing them for listing under the Endangered Species Act (ESA); these species have
no legal protection under the ESA.
Cavity-nester—Species that nests in cavities in the trunk of a tree or snag.
Cluster analysis (hierarchical)—Procedure that places objects into groups or clusters suggested by the data,
so that objects in a given cluster tend to be similar to one another, and objects from different clusters tend to be
dissimilar. In hierarchical cluster analysis, clusters are arranged such that a cluster may be contained entirely
within another cluster; however, no other type of overlap between clusters is allowed.
Coarse woody debris—Fallen trees, snags, and decaying logs and large limbs distributed across the forest floor
that are >10 cm (4 in) in diameter.
Composite ecological integrity—An integrity rating that combines the five component integrity ratings (forestland, rangeland, forestland hydrologic, rangeland hydrologic, and aquatic systems). Estimated by comparing the
component integrity ratings and knowledge of actual conditions with how each subbasin met definitions described
for high ecological integrity. (See Quigley and others [1996] for details.)
Contrast species—A species that uses two major structural stages in close proximity.
Conservation Reserve Program (CRP)—Provision of the 1985 Food Security Act that allows the Federal
Government to pay farmers to set aside highly erodible cropland. In lieu of planting traditional crops, farmers
instead convert the land to less intensive uses such as plantings of pasture or perennial grasses, trees, or other
perennial vegetation cover for at least 10 years.
Cover type (CT)—A vegetation classification depicting genera, species, group of species, or life form of tree,
shrub, grass, or sedge, or a dominant physical feature (for example water or rock) or land use (for example urban
or road). When a genus or species name is given to the cover type at a broad scale, it is typically representative of
a complex of species and genera with similar characteristics.
522
Current conditions—Conditions reflecting a coarse, general depiction of the basin circa 1990 (representative of
the 1985-95 decade).
Disturbance regime—Natural pattern of periodic disturbances, such as fire or flood, followed by a period of
recovery from the disturbance, e.g., regrowth of a forest after a fire.
Dwarf mistletoe broom—Structure of dense, misshapen branches formed on trees infected with dwarf mistletoe;
begins as a spindle-shaped branch swelling at the point of infection, progressing after several years to distinctive
shoots on swollen branches.
Early seral—Communities that occur early in the vegetation successional path and generally have less complex
structural development than later successional communities.
Ecological integrity—The maintenance of native and desired nonnative species and associated processes.
Ratings of ecological integrity combined analysis based on descriptive data layers, empirical process models,
trend analysis, and expert judgement. Subbasins were assigned a high, medium, or low score. (See Quigley and
others [1996] for details.)
Ecological reporting unit (ERU)—Subdivisions of the assessment area of the Interior Columbia Basin
Ecosystem Management Project constructed to facilitate common reporting of ecological assessment results at
a broad level. Thirteen ERUs were delineated within the basin. (See fig. 1B, vol. 1, for a map of the 13 ERUs.)
Ecological significance—Changes in cover types that met specific criteria regarding change from historical
ranges to current area; see Hann and others (1997, p. 409) for ecologically significant changes for classes,
regions, and areas.
Ecosystem management (ecosystem-based strategy)—“. . . management driven by explicit goals, executed by
policies, protocols, and practices, and made adaptable by monitoring and research based on our best understanding of the ecological interactions and processes necessary to sustain ecosystem composition, structure, and
function” (Ecological Society of America 1995).
Ecotone—The transition zone between two different plant communities, as that between forestland and rangeland.
Edge—The place where plant communities meet or where successional stages or vegetative condition within
plant communities come together.
Empirical trend—Population trend based on direct observation (e.g., Breeding Bird Survey data) rather than theory or models.
Endangered species—A wildlife species officially designated by the U.S. Fish and Wildlife Service as having
its continued existence threatened over its entire range, because its habitat is threatened with destruction, drastic
modification, or severe curtailment, or because of overexploitation, disease, predation, or other factors.
Endemic—Plants or animals that occur naturally in a certain region and whose distribution is limited to a
particular locality.
Exfoliating bark—Tree bark that has pulled away from the trunk but is still attached, thereby leaving an opening
between the trunk and bark.
Exotic—Not native; an organism or species that has been introduced into an area.
523
Expert panel—A gathering of scientific experts in species ecology, as used in this analysis, to develop the species
ecology database. Expert panels were run for this analysis by the terrestrial staff, using a modified Delphi process, for
collecting their knowledge and expertise on species ecology, source habitat associations, special habitat feature associations, range distributions, and other information.
Family (of groups)—A collection of groups of species in our analysis that share general similarities in source habitats, with the similarities arranged along major vegetative themes that are conventionally addressed by managers.
(Families were defined by using the categories shown in vol. 1, fig. 5.)
Fine scale—Assessment at the plot level within the basin; not continuous, but sampled from within the basin.
Fine-scale species of focus—Species, primarily those dependent on riparian or water habitats, meeting the criteria
of broad-scale species of focus (vol. 1, table 1), but whose source habitats were identified by experts as needing
mapping units smaller than 100 ha (247 acres) to reliably estimate their habitat abundance.
GAP analysis—Coarse-filter method of evaluating large areas for conservation, in which gaps in protection of
biodiversity (typically indicated by vegetation types and vertebrate species) are identified.
Genetic drift—Chance process in which allele frequency changes in a random fashion; less important in large
populations.
Green stripping—Land management method used to slow or stop the spread of wildfire by the strategic placement of strips of fire-resistant vegetation.
Group (of species)—A collection of species in our analysis with similarities in source habitats; groups were
initially delineated by using hierarchical cluster analysis and subsequently refined after consultation with species
experts.
Habitat outcomes—Projections of conditions for habitats at the specified points in time (historical, current, and
100 years in the future) under each alternative of the basin draft environmental impact statements.
Heart rot—Decay of the inner xylem (heartwood) of living trees caused by specialized fungi.
Hibernaculum—Habitat niches where certain animals (e.g., bats) overwinter, such as caves, mines, tree hollows,
or loose bark.
Historic range of variability (HRV)—The variability of regional or landscape composition, structure, and disturbances, during a period of several cycles of the common disturbance intervals, and similar environmental gradients.
The historical 1,000-year period, or a subset of that period, is commonly used as the “window” for HRV; see Hann
and others (1997) for details.
Historical conditions—Conditions reflecting a coarse, general depiction of how the basin might have appeared
circa 1850 to 1900, before major changes caused by Euro-American settlement, based on historical records,
photographs, and computer simulations.
Hydrologic unit code (HUC)—A nested delineation of watersheds of similar size and scale, four levels of
which were developed by the U.S. Geological Survey. Two additional nested levels were delineated for the interior
Columbia basin scientific assessment. The broadest level is the region, second is the subregion, third is the basin,
fourth is the subbasin, fifth is the watershed, and sixth is the subwatershed.
524
Hypogeous—Growing or remaining underground.
The Interior Columbia Basin Ecosystem Management Project (ICBEMP)—The ICBEMP was established by
the Eastside Ecosystem Management Project charter in January 1994. The total assessment area is 58 million ha
(144 million acres), 31 million ha (76 million acres) of which are administered by 35 National Forests and 17
BLM districts.
Key environmental correlate (KEC)—The set of habitat and other biological and physical attributes of an
environment that most influence the realized fitness (requirements) of a given species or that associate with
species occurrences (associates). The KECs include vegetation cover types (such as lodgepole pine forests),
structural stages (such as open canopy stand), substrates (such as down wood), and other environmental factors
not traditionally included in descriptions of species habitats (such as hunting pressure, proximity to urban areas,
air quality, and trophic interactions with other species).
Key ecological function (KEF)—The primary set of activities performed by organisms that affect the ecological
function of their ecosystems. An example is decomposition of byproducts of decaying organic material (such as by
the invertebrate Argilophilus hammodi), or creation of burrows (such as by the American badger (Taxidea taxus))
that can be occupied by secondary burrow users (such as longnose leopard lizard (Gambelia wislizenii)).
Late seral—Vegetative communities that occur in the later stage of the successional path with mature, generally
larger plants that dominate the overstory.
Legacy tree—Large (>53 cm [21 in] d.b.h.), mature trees that remain in a managed forest stand through two or
more rotations or silvicultural entries.
Lentic—Pertaining to or living in still water.

of timber harvest; they typically contain relatively few large snags or trees >53 cm (21 in) d.b.h. (see table 4, vol.
1 for specifications of crown cover percentages and tree size classes for managed young forests).
Management indicator species—Those species whose response to environmental conditions is assumed to
index like responses of a larger number of species and whose habitats can therefore be managed to benefit a larger
set of species; more broadly, species for which a set of management guidelines has been written.
Mast—Fruit of the oak, beech, or other forest trees; used as food by birds and other animals.
Mesic—Pertaining to conditions of moderate moisture or water supply; in this document, areas receiving >30 cm
(12 in) annual precipitation.
525
Microbiotic crust—A soil crust formed by lichens, moss, or algae that aids in stabilizing soils in arid environments, reducing their susceptibility to wind erosion. Prone to deterioration resulting from trampling or air pollution. Also referred to as cryptogamic crust.
Microhabitat—Habitat containing fine-grained features that cannot be measured accurately by using a 1-km2
(0.4-mi2) pixel.
Mid scale—Analyses at the subwatershed scale (sixth field hydrologic unit codes). Considered the context of the

during winter but breed elsewhere.
Migratory—Species that spend part of the year outside the basin.
Monitoring—A process of collecting information to evaluate whether or not objectives of a project are being

that can be used to validate assumptions, alter decisions, change implementation, or maintain current management
direction.
Mycorrhiza—A symbiotic association of the mycelium of a fungus with the roots of certain plants.
Native—Indigenous; living naturally within a given area.
Natural hydrologic regime—The original regime of water movement, unaltered by anthropogenic activities.

(between the Tropics of Cancer and Capricorn) in Mexico, the Caribbean Islands, or Central or South America.
Old forest—A forest structural stage with >30 percent crown cover of large trees (>53.2 cm [20.9 in] d.b.h.);
see table 4, volume 1 for further specifications.
Patch—Surface area that is nonlinear and differs in appearance from its surroundings.
Pixel—A contraction of the words “picture element.” A data element of a raster matrix or grid map; equivalent to
a cell.
Physiographic region—A region defined by geographical features of the Earth’s surface (e.g., mountains and
river basins); in this document, used specifically to refer to regions delineated by “Partners in Flight” for planning
and for collecting population trend data, based on biotic communities and bird distribution. (Partners in Flight is a
nonadvocacy coalition of agencies, nongovernmental organizations, private industry, and individuals dedicated to
the conservation of all birds and their habitats in the Northern Hemisphere.)
526
Population sink—Areas in which mortality rates are such that populations decline in these areas, rather than
increase or remain static.
Population viability—The likelihood of continued existence of a well-distributed population or species for a
specified period. For most scientific analyses, the period is 100 years. For example, high viability is a high likelihood of continued existence of well-distributed populations for a long period (a century or longer).
Potential vegetation group (PVG)—A group of potential vegetation types that have similar environmental
conditions and are dominated by similar types of plants (for example, the dry shrub PVG). They are often
grouped by similar types of life forms.
Potential vegetation type (PVT)—A potential vegetation type is a kind of physical and biological environment,
that produces a kind of vegetation, such as the dry Douglas-fir (Pseudotsuga menziesii) type. Potential vegetation
types are identified by indicator species of similar environmental conditions. For example, Douglas-fir (Pseudotsuga
menziesii) indicates a cooler and moister environment than ponderosa pine (Pinus ponderosa). Because of growth,
mortality, and disturbance of the vegetation, many other kinds of vegetation will occur on this type through time.
In many cases, the indicator species will not be present, due to disturbance. Douglas-fir is simply an indicator,
and name, for the kind of physical and biological environment stratification that is used for prediction of
response.
Primary excavator—A species that digs or chips out cavities in wood to provide itself or its mate with a site for
nesting or roosting.
Resident—Species that reside year-long within the basin.
Resident summer habitat—Source habitats used for survival or reproduction or rearing, or all three, late spring
through early fall, by species who live year-long within the basin.
Resident winter habitat—Source habitats used for survival during late fall through early spring by species that
live year-long within the basin.
Resident year-long habitat—Source habitats used commonly throughout the year by a species to meet all
seasonal life functions.
Riparian area—Area with distinctive soils and vegetation between a stream or other body of water and the
adjacent upland; includes wetlands and those portions of flood plains and valley bottoms that support riparian
vegetation.
Season of habitat function—Functional period (e.g., resident summer, migrant winter) in which a species occurs
in the basin, defined for both residents and migrants.
Selection harvest—Uneven-aged silvicultural system in which trees are removed singly or in small groups from
a large area each year. Regeneration is primarily natural, and the stand is ideally composed of many ages.
Seral stage—The developmental stages of a plant community not including the climax community.
Shrub steppe—Habitats characterized in western North America by woody, midheight shrubs and perennial
bunchgrasses; typically arid, with annual precipitation averaging <36 cm (14 in) over much of the region.

Source environment—The composite of all environmental conditions occurring in a specified area and time that
result in stationary or positive population growth.
Source habitat—Those characteristics of macrovegetation that contribute to stationary or positive population
growth. Distinguished from habitats associated with species occurrence; such habitats may or may not contribute
to long-term population persistence. Source habitats contribute to source environments.
Special habitat features—Nonvegetative factors or finer scale characteristics of vegetation that contribute to
stationary or positive population growth, such as snags, down logs, or caves.
Species of focus—Terrestrial vertebrates for which there is ongoing concern about population or habitat status.

Structural stage (ST)—A stage of development of a vegetation community that is classified on the dominant
processes of growth, development, competition, and mortality.
Subbasin—The fourth delineation within the hydrologic unit code system. Provides a delineation generally of
a river, or group of rivers, that flow into a basin. The 164 subbasins within the assessment area average about
345 000 ha (852,495 acres).
Subnivean—Beneath the surface of the snow.
Subwatershed—The sixth delineation within the hydrologic unit code system. Provides a delineation of a group
of streams that flow into a watershed. The 7,654 subwatersheds within the assessment area average about 7700 ha
(19,027 acres).
Succession—The more or less predictable changes in species composition in an ecosystem over time, often in a
predictable order, following a natural or human disturbance, e.g., the development of a series of plant communities (called seral stages) after a major disturbance.
Sympatric—Speciation in which a new species arises within the geographic range of its parental form.
Talus—Fragments of rock and other soil material accumulated by gravity at the foot of cliffs or steep slopes.

seral stage that has similar characteristics for interpretation of terrestrial habitat values.
Threatened species—A wildlife species officially designated by the U.S. Fish and Wildlife Service as having
its existence threatened in a localized area, such as a state or smaller area, because its habitat is threatened with
destruction, drastic modification, or severe curtailment, or because of overexploitation, disease, predation, or
other factors.
528
