What Is Treesearch?
Treesearch is an online system for locating and delivering publications by
Research and Development scientists in the USDA Forest Service. Publications
in the collection include research monographs published by the agency as well
as papers written by our scientists but published by other organizations in their
journals, conference proceedings, or books. Research results behind these
publications have been peer-reviewed to ensure the best quality of science.
Searching for
Publications
Treesearch lets you search
listings by author, keyword,
originating station, or date.
Keyword searches examine
both the title and abstract.
Viewing
and Printing
Publications
Once you have selected
a publication, you can
view and print the entire
publication online. All
publications listed in
Treesearch have their
full text available online,
usually in Adobe’s
Portable Document Format
(PDF). In some cases, the

Tangled trends for temperate rain forests as
temperatures tick up. Science Findings 149.
Portland, OR: U.S. Department of Agriculture,
Forest Service, Pacific Northwest Research Station.
6 p.
Climate change is altering growing conditions in
the temperate rain forest region that extends from
northern California to the Gulf of Alaska. Longer,
warmer growing seasons are generally increasing
the overall potential for forest growth in the region.
However, species differ in their ability to adapt to
changing conditions. For example, researchers with
the Pacific Northwest Research Station examined
forest trends for southeastern and south-central
Alaska and found that, in 13 years, western redcedar
showed a 4.2-percent increase in live-tree biomass,
while shore pine showed a 4.6-percent decrease. In
general, the researchers found that the amount of
4
live-tree biomass in extensive areas of unmanaged,
higher elevation forest in southern Alaska increased
by as much as 8 percent over the 13-year period,
contributing to significant carbon storage. Hemlock
dwarf mistletoe is another species expected to fare
well under warmer conditions in Alaska. Model
projections indicate that habitat for this parasitic
species could increase 374 to 757 percent over the
next 100 years. This could temper the prospects for
western hemlock—a tree species otherwise expected
to do well under future climate conditions projected
for southern Alaska. In coastal forests of Washington and Oregon, water availability may be a limiting
factor in future productivity, with gains at higher
elevations but declines at lower elevations.
Keywords: Climate change, Alaska, biomass, dwarf
mistletoe, hemlock, yellow-cedar.

Forest in decline: yellow-cedar research yields
prototype for climate change adaptation
planning. Science Findings 150. Portland, OR: U.S.
Department of Agriculture, Forest Service, Pacific
Northwest Research Station. 6 p.
Yellow-cedar has been dying across 600 miles of
North Pacific coastal rain forest—from Alaska
to British Columbia—since about 1880. Thirty
years ago, a small group of pathologists began
investigating possible biotic causes of the decline.
When no biotic cause could be found, the scope
broadened into a research program that eventually
Recent Publications of the Pacific Northwest Research Station, First Quarter, 2013
encompassed the fields of ecology, soils, hydrology,
ecophysiology, dendrochronology, climatology,
and landscape analysis. Combined studies
ultimately revealed that the loss of this culturally,
economically, and ecologically valuable tree is
caused by a warming climate, reduced snowpack,
poor soil drainage, and the species’ shallow
roots. These factors lead to fine-root freezing,
which eventually kills the trees. The considerable
knowledge gained while researchers sought the
cause of widespread yellow-cedar mortality
forms the basis for a conservation and adaptive
management strategy. A new approach to mapping
that overlays topography, cedar populations, soil
drainage, and snow enables land managers to
pinpoint locations where yellow-cedar habitat is
expected to be suitable or threatened in the future,
thereby bringing climate change predictions into
management scenarios. The research program
serves as a prototype for evaluating the effects of
climate change in other landscapes. It shows the
value of long-term, multidisciplinary research that
encourages scientists and land managers to work
together toward developing adaptive management
strategies.

Effects of climatic variability and change on
forest ecosystems: a comprehensive science
synthesis for the U.S. forest sector. Gen.
Tech. Rep. PNW-GTR-870. Portland, OR: U.S.
Department of Agriculture, Forest Service,
Pacific Northwest Research Station. 265 p.
This report is a scientific assessment of the
current condition and likely future condition of
forest resources in the United States relative to
climatic variability and change. It serves as the
U.S. Forest Service forest sector technical report
for the National Climate Assessment and includes
descriptions of key regional issues and examples of
a risk-based framework for assessing climate-change
effects. By the end of the 21st century, forest ecosystems in the United States will differ from those
of today as a result of changing climate. Although
increases in temperature, changes in precipitation,
higher atmospheric concentrations of carbon
dioxide (CO2), and higher nitrogen (N) deposition
may change ecosystem structure and function, the
most rapidly visible and most significant short-term
effects on forest ecosystems will be caused by
altered disturbance regimes. For example, wildfires,
insect infestations, pulses of erosion and flooding,
and drought-induced tree mortality are all expected
to increase during the 21st century. These direct
and indirect climate-change effects are likely to
cause losses of ecosystem services in some areas,
but may also improve and expand ecosystem
services in others. Some areas may be particularly
vulnerable because current infrastructure and
resource production are based on past climate and
steady-state conditions. The ability of communities
with resource-based economies to adapt to climate
change is linked to their direct exposure to these
changes, as well as to the social and institutional
structures present in each environment. Human
communities that have diverse economies and are
resilient to change today will also be prepared
for future climatic stresses. Significant progress
has been made in developing scientific principles
and tools for adapting to climate change through
science-management partnerships focused on
education, assessment of vulnerability of natural
resources, and development of adaptation strategies
and tactics. Although uncertainty exists about the
magnitude and timing of climate-change effects on
forest ecosystems, sufficient scientific information
is available to begin taking action now. Building
on practices compatible with adapting to climate
change provides a good starting point for land
managers who may want to begin the adaptation
process. Establishing a foundation for managing
forest ecosystems in the context of climate change
as soon as possible will ensure that a broad range
of options will be available for managing forest
resources sustainably.

effects, National Climate Assessment, climatesmart management, ecological disturbance, forest

ArcFuels10 system overview. Gen. Tech. Rep.
PNW-GTR-875. Portland, OR: U.S. Department
of Agriculture, Forest Service, Pacific Northwest
Research Station. 65 p.
Fire behavior modeling and geospatial analyses can
provide tremendous insight for land managers as
they grapple with the complex problems frequently
encountered in wildfire risk assessments and fire
and fuels management planning. Fuel management
often is a particularly complicated process in which
the benefits and potential impacts of fuel treatments
need to be demonstrated in the context of land
management goals and public expectations. The
fuel treatment planning process is complicated by
the lack of data assimilation among fire behavior
models and weak linkages to geographic information systems (GIS), corporate data, and desktop
office software. ArcFuels10 is a streamlined fuel
management planning and wildfire risk assessment
system that creates a trans-scale (stand to large
landscape) interface to apply various forest growth
and fire behavior models within an ArcGIS platform
to design and test fuel treatment alternatives. The
new version of ArcFuels has been implemented on
Citrix at the Forest Service Enterprise Production
Data Center, eliminating the need for desktop GIS,
improving connectivity to the corporate geospatial
databases housed at the data centers, and enabling
sharing of information among Forest Service
employees. This overview introduces ArcFuels10
and the tools available within the system. Further
information, including download information,
demonstration data, and a tutorial, can be found at

14–16, 2011, in Portland, Oregon. The conference
6
Recent Publications of the Pacific Northwest Research Station, First Quarter, 2013
brought together over 70 users of state-and-transition
simulation modeling tools—the Vegetation Dynamics Development Tool (VDDT), the Tool for Exploratory Landscape Analysis (TELSA) and the Path
Landscape Model. The goal of the conference was
to (1) provide opportunities for sharing experiences
with different applications of the tools, (2) identify
major existing conceptual or technological gaps,
and develop goals for future state-and-transition
simulation model (STSM) development, and (3) start
building an international network of STSM users.
Eighteen oral presentations and thirteen posters
were presented. This proceeding includes thirteen
papers that build on some key STSM concepts,
applications, and innovations from that conference,
and shares them with a wider audience. The goal of
these proceedings is to provide a state-of-the-science
reference for STSM modelers and users. All papers
were peer-reviewed by two blind reviewers and
one editor. The presentation of these papers reveals
that the STSM approach has been applied to a wide
range of management and land-use questions and
ecosystems, with an equally wide variation in the
amounts of scientific data and expert knowledge
available for model parameterization.

Tech. Rep. PNW-GTR-872. Portland, OR: U.S.
Department of Agriculture, Forest Service, Pacific
Northwest Research Station. 30 p.
Biomass residue produced by timber harvest
operations is estimated for the Olympic and Kitsap
Peninsulas, Washington. Scattered residues were
sampled in 53 harvest units and piled residues were
completely enumerated in 55 harvest units. Production is based on 2008 and 2009 data and is stratified
by forest location, ownership type, harvest intensity,
and harvest method. An additional sampling was
taken to ascertain the mass of wood present in a pile
of biomass: 20 piles of biomass were measured for
gross volume, processed into hog fuel, and remeasured for volume; five samples were drawn from
each pile and examined for volume, green mass, and
bone-dry mass. An equation relating mass of wood
in a pile to the gross biomass volume is derived.
Finally, the availability and average delivered cost
per ton of biomass is calculated for five delivery
centers on the Olympic Peninsula.

Estimating tree biomass, carbon, and nitrogen in
two vegetation control treatments in an 11-yearold Douglas-fir plantation on a highly productive
site. Res. Pap. PNW-RP-591. Portland, OR: U.S.
Department of Agriculture, Forest Service, Pacific
Northwest Research Station. 29 p.
We sampled trees grown with and without
competing vegetation control in an 11-year-old
Douglas-fir (Pseudotsuga menziesii var. menziesii
(Mirb.) Franco) plantation on a highly productive
site in southwestern Washington to create diameterbased allometric equations for estimating individualtree bole, branch, foliar, and total aboveground
biomass. We used these equations to estimate
per-hectare aboveground biomass, nitrogen (N), and
carbon (C) content, and compared these results to
(1) estimates based on biomass equations published
in other studies, and (2) estimates made using the
mean-tree method rather than allometric equations.
Component and total-tree biomass equations were
not influenced by the presence of vegetation control,
although per-hectare biomass, C, and N estimates
were greater where vegetation control was applied.
Our biomass estimates differed from estimates using
previously published biomass equations by as much
as 23 percent. When using the mean-tree biomass
estimation approach, we found that incorporating
a previously published biomass equation improved
accuracy of the mean-tree diameter calculation.
Keywords: Douglas-fir, plantation, biomass,
