Regional population monitoring of the marbled murrelet: field and analytical methods 2007-08-16 12:00:00 The marbled murrelet (Brachyramphus marmoratus) ranges from Alaska to California and is listed under the Endangered Species Act
as a threatened species in Washington, Oregon, and California. Marbled murrelet recovery depends, in large part, on conservation
and restoration of breeding habitat on federally managed lands. A major objective of the Northwest Forest Plan (the Plan) is to
conserve and restore nesting habitat that will sustain a viable marbled murrelet population. Under the Plan, monitoring
is an
essential component and is designed to help managers understand the degree to which the Plan is meeting this objective. This report
describes methods used to assess the status and trend of marbled murrelet populations under the Plan.
Managing For Wildlife Habitat In Westside Production Forests 2007-02-20 14:00:00 On October 18, 2006, a workshop was held in Vancouver, WA, with the title "Managing for wildlife habitat in Westside
production
forests." The purpose of the workshop was to provide prescriptions and guidelines for people who manage Westside forests (those
west of the Cascade Mountains' crest) primarily for wood production, but because of mandate or personal preference, want to
integrate wildlife values. The audience included over 150 professionals from forest industry, consulting firms, and public and
tribal forest and wildlife management agencies. This proceedings includes ten papers based on oral presentations at the workshop
plus a synthesis paper summarizing workshop themes, discussions, and related information. Topics include a history of wildlife
management research in the Pacific Northwest, elements of habitat and how to manage for them, the challenges of appropriately
implementing ecosystem management, and economic implications to private forestland owners Read more:Production
Growth of Bear-Damaged Trees In A Mixed Plantation of Douglas-Fir and Red Alder 2007-02-02 12:25:10 Incidence and effects of tree damage by black bear (Ursus americanus altifrontalis) in a 50-year-old, coast Douglas
-fir
(Pseudotsuga menziesii (Mirb.) Franco var. menziesii) plantation are described. Bears girdled or partially girdled 35 dominant
or codominant Douglas-fir trees per acre, but only in that portion of the plantation that had been interplanted at age 4 with red alder
(Alnus rubra Bong). No red alder were damaged. Bears damaged Douglas-fir in this stand on at least four occasions between 1929
(planting) and 1991. Fully girdled Douglas-fir (six per acre in 1976) died within 2 to 14 years. Of the 29 per acre
partially girdled trees, 17 percent died in the 16 years of observation, compared to 9 percent of nondamaged trees. Crosssectional growth of
surviving damaged trees exceeded that of matched, nondamaged trees by about 30 percent at three heights on the bole: 6 ft, 4.5 ft, and
immediately above the damaged area. Death of six large Douglas-fir trees per Read more:Growth

Roger Lake Research Natural Area: Guidebook Supplement 29 2006-12-08 14:00:00 Roger Lake ResearchNatural
Area (RNA), a 174.7-ha reserve in north-central Washington, contains a rich diversity of landforms,
plant communities, and wildlife habitats. Spreading outward from the lake itself, sedge and sphagnum fens give way to upland coniferous forest,
granitic cliffs, and a relictual, high-altitude big sagebrush-whitebark pine (Artemisia tridentata-Pinus albicaulis) meadow.
Five sensitive plant species and several vertebrate species that are rare in the region occur in the RNA. Dynamic ecological processes in action
in the RNA are revealed in the paludification of the forest edge; aging, broken beaver dams; and widespread bark beetle-induced conifer
mortality. Read more:Roger

Assessment of The Risk of Invasion of National Forest Streams In The Pacific Northwest By Farmed Atlantic Salmon 2006-11-17 14:00:00 This report describes the evidence for invasion of PacificNorthwest
streams by Atlantic salmon (Salmo salar) that have escaped from
marine salmon farms, and assesses the potential impact of farmed salmon invasion on native fishes inhabiting streams on NationalForest
System
lands. The current risk to streams on National Forest lands in the Pacific Northwest from Atlantic salmon invasions appears to be low and is
limited to a few areas in northwest Washington and southeast Alaska. However, long-term risks may be substantial if fish continue to escape
from marine rearing pens or freshwater hatcheries. The two greatest threats appear to be that (1) Atlantic salmon could transmit a serious
disease or parasite to native fishes, and (2) escaped salmon could eventually adapt to local conditions, leading to self-sustaining
populations. If Atlantic salmon populations are eventually established, this species' preference for swiftly flowing stream habitats could
facilitate Read more:Assessment

Red Alder: A State of Knowledge 2006-04-12 18:25:36 In March 23-25, 2005, an international symposium on red alder was held at the University of Washington Center for Urban Horticulture in
Seattle, WA. The symposium was entitled Red Alder: A State
of Knowledge
and brought together regional experts to critically
examine the economic, ecological and social values of red alder. The primary goal of the symposium was to discuss new advances in the
understanding of red alder biology and silviculture, changing market and nonmarket values, and the current regulatory climate for management
of alder. This proceedings includes 14 papers based on oral presentations given at the symposium. These papers highlight some of the key
findings from the history, ecology, biology, silviculture and economics sessions presented at the red alder symposium.
The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management 2006-04-05 18:25:36 The PacificNorthwestResearchStation
launched a Biodiversity Initiative to assist natural resource professionals in integrating complex
biodiversity concepts into natural resource management processes. We canvassed clients from various affiliations to determine the main challenges
they face in biodiversity management, to define their information needs, and to understand how best to deliver biodiversity information within a
collaborative framework. The biodiversity management challenges that emerged included (1) the lack of well-defined biodiversity
management policies, (2) understanding and quantifying the interaction effects between a number of factors (e.g., disturbance types,
management practices) and biodiversity, (3) the lack of applied biodiversity monitoring strategies, (4) difficulty in locating
and accessing biodiversity information, and (5) balancing conflicting values relating to biodiversity. We also list the biodiversity

A Social History of Wild Huckleberry Harvesting In The Pacific Northwest 0000-00-00 00:00:00 Once gathered only for subsistence and cultural purposes, wild huckleberries are now also harvested commercially. Drawing on archival research as
well as harvester and producer interview and survey data, an inventory of North American wild huckleberry plant genera is presented, and the wild
huckleberry harvesting patterns of early Native Americans and nonindigenous settlers are described. The social, technological, and environmental
changes that gave rise to the commercial industry in the PacificNorthwest
by the 1920s and the industry's demise after World War II are
explained. The resurgence of the commercial wild huckleberry industry in the mid-1980s and national forest management issues related to the
industry are presented as are possible strategies that land managers could develop to ensure wild huckleberry, wildlife, and cultural
sustainability. Read more:Social

A Practical Guide To Oak Release 2006-02-28 17:25:36 Oregon white oak savannas and woodlands represent a biological and cultural legacy in the Pacific Northwest. Many Oregon white oak stands are
deteriorating owing to invasion and eventual overtopping by Douglas-fir or other conifers. Releasing the shade-intolerant oak trees from
overtopping conifers can often restore these oak stands. When planning a release operation, there are many factors to consider such as timing and
intensity of release, which trees to select for release, and management of the understory. A carefully executed oak release can minimize damage to
oak trees, and followup treatments may reduce the spread of invasive plants. This guide answers the most commonly asked questions related to oak
release. Read more:Practical

Users Guide For FRCS: Fuel Reduction Cost Simulator Software 2006-02-28 17:25:36 The Fuel Reduction Cost Simulator
(FRCS) spreadsheet application is publicdomain software used to estimate costs for fuel reduction
treatments involving removal of trees of mixed sizes in the form of whole trees, logs, or chips from a forest. Equipment production rates were
developed from existing studies. Equipment operating cost rates are from December 2002 prices for new equipment and wage rates for the Pacific
Northwest. These cost assumptions can be modified by the user. There are four ground-based systems, four cable systems, and two helicopter
systems. Cost estimates are in U.S. dollars per 100 cubic feet, per green ton, and per acre. Read more:Guide

A review of the literature on seed fate in whitebark pine and the life history traits of Clark's nutcracker and pine squirrels 2008-04-21 14:15:00 Whitebark pine is a critical component of subalpine ecosystems in western North America, where it contributes to biodiversity and ecosystem
function and in some communities is considered a keystone species. Whitebark pine is undergoing rangewide population declines attributed to
the combined effects of mountain pine beetle, white pine blister rust, and fire suppression. The restoration and maintenance of whitebark
pine populations require an understanding of all aspects of seed fate. In this paper, we review
the literature on seed dispersal in whitebark
pine. Clark
's nutcracker, pine squirrels, and scatter-hoarding rodents are all known to influence whitebark pine seed fate and
ultimately affect the ability of whitebark pine populations to regenerate. We also provide a gener
