ia The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management By www.fs.fed.us Published On :: Wed, 05 Apr 2006 15:25:36 PST The Pacific Northwest Research Station 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 information product needs of clients, as well as preferred technology transfer methods, and we discuss the future direction of the Biodiversity Initiative. Full Article
ia Does Wood Slow Down Sludge Dragons? The Interaction Between Riparian Zones and Debris Flows In Mountain Landscapes By www.fs.fed.us Published On :: Thu, 07 Sep 2006 12:00:36 PST Conservation measures for aquatic species throughout the Pacific Northwest rely heavily on maintaining forested riparian zones. A key rationale for this strategy is that the presence of standing and downed trees next to streams will provide a continuous source of wood, which is an important structural component of aquatic habitat.

ia Yellow-Cedar Decline In The North Coast Forest District of British Columbia By www.fs.fed.us Published On :: Mon, 28 Nov 2005 15:25:36 PST The distribution of a forest decline of yellow-cedar (Callitropsis nootkatensis (D. Don) Orsted) has been documented in southeast Alaska, but its occurrence in British Columbia was previously unknown. We conducted an aerial survey in the Prince Rupert area in September 2004 to determine if yellow-cedar forests in the North Coast Forest District of British Columbia were experiencing a similar fate as in nearby Alaska. Numerous large areas of concentrated yellow-cedar mortality were found, extending the known distribution of the decline problem 150 km south of the Alaska-British Columbia border. The forests with the most concentrated tree death occurred at 300 to 400 m elevation, frequently on south aspects. The appearance of these forests including proximity to bogs; mixtures of dying, recently killed, and long-dead trees; and crown and bole symptoms of dying trees were all consistent with the phenomenon in southeast Alaska.

ia Financial Analysis of Fuel Treatments On National Forests In The Western United States By www.fs.fed.us Published On :: Fri, 15 Dec 2006 12:00:00 PST The purpose of this note is to provide a starting point for discussion of fire hazard reduction treatments that meet the full range of management objectives, including budget priorities. Thoughtful design requires an understanding not only of the physical and biological outcomes, but also the costs and potential revenues of applying variations of fire hazard reduction treatments in a wide range of stand conditions. This analysis was done with My Fuel Treatment Planner software and provides estimates of cost and net revenue from fire hazard reduction treatments on 18 dry forest stands from 9 national forests in the Western United States. The data and software tools used in this analysis are all available, so these analyses can be easily modified to address a wider range of treatments and conditions. Full Article
ia Potential vegetation hierarchy for the Blue Mountains section of northeastern Oregon, southeastern Washington, and westcentral Idaho By www.fs.fed.us Published On :: Thu, 16 Aug 2007 09:00:00 PST The work described in this report was initiated during the Interior Columbia Basin Ecosystem Management Project (ICBEMP). The ICBEMP produced a broad-scale scientific assessment of ecological, biophysical, social, and economic conditions for the interior Columbia River basin and portions of the Klamath and Great Basins. The broad-scale assessment made extensive use of potential vegetation (PV) information. This report (1) discusses certain concepts and terms as related to PV, (2) describes how a PV framework developed for the broad-scale ICBEMP assessment area was stepped down to the level of a single section in the national hierarchy of terrestrial ecological units, (3) describes how fine-scale potential vegetation types (PVTs) identified for the Blue Mountains section were aggregated into the midscale portion of the PV hierarchy, and (4) describes the PVT composition for each of the midscale hierarchical units (physiognomic class, potential vegetation group, plant association group).

ia Growth of Douglas-fir near equipment trails used for commercial thinning in the Oregon Coast Range By www.fs.fed.us Published On :: Fri, 18 Jan 2008 15:08:00 PST Soil disturbance is a visually apparent result of using heavy equipment to harvest trees. Subsequent consequences for growth of remaining trees, however, are variable and seldom quantified. We measured tree growth 7 and 11 years after thinning of trees in four stands of coast Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb. Franco)) where soil disturbance was limited by using planned skid trails, usually on dry soils. The three younger stands had responded to nitrogen fertilizer in the 4 years before thinning, but only one stand showed continued response in the subsequent 7- or 11-year period after thinning. The most consistent pattern observed was greater growth of residual trees located next to skid trails. The older stand also showed greater growth in trees located next to skid trails, whereas tillage of skid trails failed to benefit growth of nearby residual trees for the first 7 years after tillage. We conclude that traffic that compacted soil only on one side of residual trees did not reduce growth of nearby trees. Full Article
ia Water and people: challenges at the interface of symbolic and utilitarian values By www.fs.fed.us Published On :: Tue, 19 Feb 2008 11:10:00 PST The demand for water is rapidly increasing, but the uses to which that water is put and the values society places on water are changing dramatically. Water is the source of life, the sustenance for living, the resource needed for manufacturing, mining, agriculture; the element required to grow our lawns, to water our landscaping, to shower us with refreshment; it is the place where we play; it provides the snow for our winter recreation, and it provides the habitat for much of our wildlife. Water in contemporary American society is more than a simple physical entity, its symbolic values, and noninstrumental uses are growing in significance. As with many Native American cultures, water is as much a symbol as it is something to extract and use in the production of commercial products. This book is about the issues associated with these symbolic values and uses of water: the challenges they present--in our language, in our allocation mechanisms, in our communication--the conflicts raised; and the potential for resolving the difficult, contentious and complex issues concerning the use of water for various purposes. It is as much about framing the questions about symbolic values of water as it is anything else. Full Article
ia Lichen bioindication of biodiversity, air quality, and climate: baseline results from monitoring in Washington, Oregon, and California By www.fs.fed.us Published On :: Thu, 3 Apr 2008 06:31:00 PST Lichens are highly valued ecological indicators known for their sensitivity to a wide variety of environmental stressors like air quality and climate change. This report summarizes baseline results from the U.S. Department of Agriculture, Forest Service, Forest Inventory and Analysis (FIA) Lichen Community Indicator covering the first full cycle of data collection (1998-2001, 2003) for Washington, Oregon, and California. During this period, FIA conducted 972 surveys of epiphytic macrolichen communities for monitoring both spatial and long-term temporal trends in forest health. Major research findings are presented with emphasis on lichen biodiversity as well as bioindication of air quality and climate. Considerable effort is devoted to mapping geographic patterns and defining lichen indicator species suitable for estimating air quality and climate. Full Article
ia Forest inventory-based estimation of carbon stocks and flux in California forests in 1990 By www.fs.fed.us Published On :: Mon, 21 Apr 2008 11:20:00 PST Estimates of forest carbon stores and flux for California circa 1990 were modeled from forest inventory data in support of California's legislatively mandated greenhouse gas inventory. Reliable estimates of live-tree carbon stores and flux on timberlands outside of national forest could be calculated from periodic inventory data collected in the 1980s and 1990s; however, estimation of circa 1990 flux on national forests and forests other than timberland was problematic owing to a combination of changing inventory protocols and definitions and the lack of remeasurement data on those land categories. We estimate annual carbon flux on the 7.97 million acres of timberlands outside of national forests (which account for 24 percent of California's forest area and 28 percent of its live tree aboveground biomass) at 2.9 terragrams per year.

ia True fir spacing trials: 10-year results By www.fs.fed.us Published On :: Thu, 01 May 2008 08:15:00 PST Eighteen precommercial thinning trials were established in true fir-hemlock stands in the Olympic Mountains and the west side of the Cascade Range during the period 1987 through 1994. This paper updates a previous report, with results for the first 10 years after establishment. Results are given for (1) all trees, (2) the largest 80 per acre of any species, and (3) those noble fir (Abies procera Rehd.) and Pacific silver fir (Abies amabilis Dougl. ex Forbes) included in the largest 80 per acre. Diameter growth of all species increased with increase in spacing. Height growth of Pacific silver fir decreased with increase in spacing. The largest 80 trees per acre of all species showed some increase in diameter and basal area growth with increased spacing, while height growth declined slightly and volume growth was nearly constant. Over time, these installations will provide a unique source of information on early development of managed stands of these species, for which little information is now available. Full Article
ia User guide for HCR Estimator 2.0: software to calculate cost and revenue thresholds for harvesting small-diameter ponderosa pine By www.fs.fed.us Published On :: Thu, 22 May 2008 14:00:00 PST The HCR (Harvest Cost-Revenue) Estimator is engineering and financial analysis software used to evaluate stand-level financial thresholds for harvesting smalldiameter ponderosa pine (Pinus ponderosa Dougl. ex Laws.) in the Southwest United States. The Windows-based program helps contractors and planners to identify costs associated with tree selection, residual handling, transportation of raw materials, and equipment used. Costs are compared against total financial return for regionally based market opportunities to arrive at potential net profit. Information is used to identify per-acre cost thresholds, for contract appraisal, and for prioritizing project planning for wildfire fuel reduction treatments and forest restoration efforts.

ia Wood energy for residential heating in Alaska: current conditions, attitudes, and expected use. By www.fs.fed.us Published On :: Tue, 20 Jul 2010 14:10:00 PST This study considered three aspects of residential wood energy use in Alaska: current conditions and fuel consumption, knowledge and attitudes, and future use and conditions. We found that heating oil was the primary fuel for home heating in southeast and interior Alaska, whereas natural gas was used most often in south-central Alaska (Anchorage). Firewood heating played a much more important role as a secondary (vs. primary) heating source in all regions of Alaska. In interior Alaska, there was a somewhat greater interest in the use of wood energy compared to other regions. Likewise, consumption of fossil fuels was considerably greater in interior Alaska.

ia Quantifying competitive ability of perennial grasses to inhibit Scotch broom. By www.fs.fed.us Published On :: Fri, 10 Jun 2011 14:35:00 PST Greenhouse pot studies were conducted to quantify the competitive abilities of three native perennial grass species to inhibit development of Scotch broom (Cytisus scoparius (L.) Link ) seedlings: spike bentgrass (Agrostis exarata Trin. ), blue wildrye (Elymus glaucus Buckley), and western fescue (Festuca occidentalis Hook. ). In single-species stands (1) soil water content decreased with increasing grass density, (2) soil water depletion per plant differed among species as ratios of 2.4:1.3:1 for bentgrass, fescue, and wildrye, respectively, and (3) average percentage of ground cover per plant was ranked by species as bentgrass (14 percent), wildrye (8 percent), broom (8 percent), and fescue (5 percent). Regression models predicted 90, 85, and 72 percent reductions in average biomass per plant of broom when grown with approximately 250 plants/m2 of bentgrass, wildrye, and fescue, respectively. Bentgrass and wildrye were more competitive than fescue because of their early-season depletion of soil water and rapid development of cover. Full Article
ia Evaluating soil risks associated with severe wildfire and ground-based logging By www.fs.fed.us Published On :: Thu, 30 Jun 2011 10:40:00 PST Rehabilitation and timber-salvage activities after wildfire require rapid planning and rational decisions. Identifying areas with high risk for erosion and soil productivity losses is important. Moreover, allocation of corrective and mitigative efforts must be rational and prioritized. Our logic-based analysis of forested soil polygons on the Okanogan-Wenatchee National Forest was designed and implemented with the Ecosystem Management Decision Support (EMDS) system to evaluate risks to soil properties and productivity associated with moderate to severe wildfire and unmitigated use of ground-based logging equipment. Soil and related data are from standard National Cooperative Soil Surveys. We present results from one national forest management unit, encompassing 6,889 soil polygons and 69 438 ha. In the example area, 36.1 percent and 46.0 percent of the area were classified as sensitive to impacts from severe wildfire and unmitigated use of logging equipment, respectively, and there was a high degree of correspondence between the map of units sensitive to wildfire and the map of units sensitive to heavy equipment. We discuss options for extending the current model and considerations for validating key model components. Full Article

ia Seasonal neighbors: residential development encroaches on mule deer winter range in central Oregon. By www.fs.fed.us Published On :: Fri., 22 Mar 2012 13:40:00 PST Mule deer populations in central Oregon are in decline, largely because of habitat loss. Several factors are likely contributors. Encroaching juniper and invasive cheatgrass are replacing deer forage with high nutritional value, such as bitterbrush and sagebrush. Fire suppression and reduced timber harvests mean fewer acres of early successional forest, which also offer forage opportunities. Human development, including homes and roads, is another factor. It is this one that scientists with the Pacific Northwest Research Station and their collaborators investigated in a recent study. Full Article
ia The Asian wood pellet markets. By www.fs.fed.us Published On :: Tue., 29 May 2012 8:55:00 PST This study examines the three major wood pellet markets in Asia: China, Japan, and South Korea. In contrast to the United States, where most wood pellets are used for residential heating with pellet stoves, a majority of the wood pellets in Asia are used for co-firing at coal-fired power plants. Our analysis indicated that Japan is the largest importer of wood pellets in Asia and that most of the pellets it consumes are used for co-firing at power plants. South Korean wood pellet imports are fairly small; however, South Korea is striving to increase its percentage of renewable energy, which could benefit the wood pellets industry. We found that China, the largest energy consumer in Asia, has an established wood pellet market. However, a majority of these wood pellets are manufactured in China, thus imports are minimal. A consistent factor in these nations is that their governments are promoting renewable energy, leading to policies that are driving demand for wood pellets. As these countries strive to meet their renewable energy targets, their wood pellet consumption is projected to grow. Full Article
ia Synthesis of wind energy development and potential impacts on wildlife in the Pacific Northwest, Oregon and Washington. By www.fs.fed.us Published On :: Fri, 20 Jul 2012 13:40:00 PST Nationally, there is growing public interest in and policy pressure for developing alternative and renewable sources of energy. Wind energy facilities in the Pacific Northwest expanded rapidly over the past decade, as a result of state policies that encourage wind energy development. While much of the development thus far has occurred on private lands, there is interest in expanding onto federal land. However, there are concerns about the impacts of wind energy on wildlife. Wind energy facilities have the potential to harm wildlife both directly through collisions with turbines and transmission lines, and indirectly by modifying habitat. This report synthesizes the available scientific literature on potential wind energy facility impacts to wildlife, with a focus on the Pacific Northwest (Oregon and Washington), and summarizes the current best management practices recommended in federal and state guidelines for wind energy development. Research gaps in our understanding of wind energy impacts on wildlife remain. Future research needs include long-term, multisite, experimental studies of wind energy impacts on wildlife, improved ability to estimate population-level and cumulative impacts of wind energy facilities on wildlife, and better knowledge of key wildlife species' migration and demography.

ia True fir spacing and yield trials-a 20-year update By www.fs.fed.us Published On :: Fri, 17 May 2013 13:40:00 PST This report updates data and comparisons from previous reports (Curtis and others 2000, Curtis 2008) on a series of precommercial thinning and yield trials in high-elevation true fir–hemlock stands, using data from the 12 replicates for which 20-year data are now available. The stands were varying mixtures of Pacific silver fir (Abies amabilis (Douglas ex Loudon) Douglas ex Forbes), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and noble fir (Abies procera Rehder). Trends noted in the 2008 report continue. Increment in top height was somewhat reduced at wide spacings. Volume increment and basal area increment increased as the residual number of trees increased. There was a small increase in diameter increment of the 80 largest trees per acre at wide spacing. Relative stand densities on the unthinned plots, as measured by stand density index (SDI) and relative density (RD), are still increasing; it appears that the maximum (not yet attained) is probably at least 20 to 25 percent greater than values observed in Douglas-fir.

ia Precommercial thinning: implications of early results from the Tongass-Wide Young-Growth Studies experiments for deer habitat in southeast Alaska. By www.fs.fed.us Published On :: Fri, 17 May 2013 13:50:00 PST This report documents the results from the first “5-year” round of understory responses to the Tongass-Wide Young-Growth Studies (TWYGS) treatments, especially in relation to their effects on food resources for black-tailed deer (Odocoileus hemionus sitkensis). Responses of understory vegetation to precommercial silviculture experiments after their first 4 to 8 years posttreatment were analyzed with the Forage Resource Evaluation System for Habitat (FRESH)-Deer model. The studies were conducted in western hemlock (Tsuga heterophylla)-Sitka spruce (Picea sitchensis) young-growth forests in southeast Alaska. All four TWYGS experiments were studied: (I) planting of red alder (Alnus rubra) within 1- to 5-year-old stands; (II) precommercial thinning at narrow and wide spacings (549 and 331 trees per hectare, respectively) in 15- to 25-year-old stands; (III) precommercial thinning at medium spacing (420 trees per hectare) with and without pruning in 25- to 35-yearold stands; and (IV) precommercial thinning at wide spacing (203 trees per hectare) with and without slash treatment versus thinning by girdling in >35-year-old stands. All experiments also included untreated control stands of identical age. FRESHDeer was used to evaluate the implications for deer habitat in terms of forage resources (species-specific biomass, digestible protein, and digestible dry matter) relative to deer metabolic requirements in summer (at two levels of requirements—maintenance only vs. lactation) and in winter (at six levels of snow depth).

ia A photographic guide to Acacia koa defects By www.fs.fed.us Published On :: Thu, 01 Aug 2013 9:55:00 PST Acacia koa (A. Gray), native to the Hawaiian Islands, has both cultural and economic significance. Koa wood is world-renowned for its extensive use in furniture, tone wood for musical instruments, and other items of cultural importance. Old-growth koa is decreasing in supply, yet dead and dying koa is still being harvested for manufacture of products. Knowledge of wood quality in the trees available for harvest is limited and colloquial in nature. We selected logs from four geographically dispersed sites on the Island of Hawaii. Defects on the face and end surfaces of each log were measured and photographed. The four most commonly occurring defects found were seam, branch, decay (log face), and heart rot. Sawing patterns were recorded so that corresponding defects on lumber could be measured and impact on volume recovery calculated for a specific defect. Included is a pictorial accounting that captures the defect indicators on the exterior of the log and the interior manifestation of the defects as seen in the lumber sawn from the log. Full Article
ia Social vulnerability and climate change: synthesis of literature By www.fs.fed.us Published On :: Wed 03 Aug 2011 10:20:00 PST The effects of climate change are expected to be more severe for some segments of society than others because of geographic location, the degree of association with climate-sensitive environments, and unique cultural, economic, or political characteristics of particular landscapes and human populations. Social vulnerability and equity in the context of climate change are important because some populations may have less capacity to prepare for, respond to, and recover from climate-related hazards and effects. Such populations may be disproportionately affected by climate change. This synthesis of literature illustrates information about the socioeconomic, political, health, and cultural effects of climate change on socially vulnerable populations in the United States, with some additional examples in Canada. Through this synthesis, social vulnerability, equity, and climate justice are defined and described, and key issues, themes, and considerations that pertain to the effects of climate change on socially vulnerable populations are identified. The synthesis reviews what available science says about social vulnerability and climate change, and documents the emergence of issues not currently addressed in academic literature. In so doing, the synthesis identifies knowledge gaps and questions for future research. Full Article
ia Exploring the role of traditional ecological knowledge in climate change initiatives By www.fs.fed.us Published On :: Fri, 17 May 2013 11:00:00 PST Indigenous populations are projected to face disproportionate impacts as a result of climate change in comparison to nonindigenous populations. For this reason, many American Indian and Alaska Native tribes are identifying and implementing culturally appropriate strategies to assess climate impacts and adapt to projected changes. Traditional ecological knowledge (TEK), as the indigenous knowledge system is called, has the potential to play a central role in both indigenous and nonindigenous climate change initiatives. The detection of environmental changes, the development of strategies to adapt to these changes, and the implementation of sustainable land-management principles are all important climate action items that can be informed by TEK. Although there is a significant body of literature on traditional knowledge, this synthesis examines literature that specifically explores the relationship between TEK and climate change. The synthesis describes the potential role of TEK in climate change assessment and adaptation efforts. It also identifies some of the challenges and benefits associated with merging TEK with Western science, and reviews the way in which federal policies and administrative practices facilitate or challenge the incorporation of TEK in climate change initiatives. The synthesis highlights examples of how tribes and others are including TEK into climate research, education, and resource planning and explores strategies to incorporate TEK into climate change policy, assessments, and adaptation efforts at national, regional, and local levels.

ia Terrestrial species viability assessments for national forests in northeastern Washington. By www.fs.fed.us Published On :: Mon, 02 Oct 2017 9:55:00 PST We developed a process to address terrestrial wildlife species for which management for ecosystem diversity may be inadequate for providing ecological conditions capable of sustaining viable populations. The process includes (1) identifying species of conservation concern, (2) describing source habitats, and other important ecological factors, (3) organizing species into groups, (4) selecting surrogate species for each group, (5) developing surrogate species assessment models; (6) applying surrogate species assessment models to evaluate current and historical conditions, (7) developing conservation considerations, and (8) designing monitoring and adaptive management. Following the application of our species screening criteria, we identified 209 of 700 species as species of concern on National Forest System lands east of the Cascade Range in Washington state. We aggregated the 209 species of conservation concern into 10 families and 28 groups based primarily on their habitat associations (these are not phylogenetic families). We selected 32 primary surrogate species (78 percent birds, 17 percent mammals, 5 percent amphibians) for application in northeastern Washington, based on risk factors and ecological characteristics. Our assessment documented reductions in habitat capability across the assessment area compared to historical conditions. We combined management considerations for individual species with other surrogate species to address multiple species. This information may be used to inform land management planning efforts currently underway on the Okanogan-Wenatchee and Colville National Forests in northeastern Washington. Full Article

ia Life cycle assessment of wood energy for residential heating—opportunities for wood pellet production in southeast Alaska. By www.fs.fed.us Published On :: Tue, 01 Aug 2017 08:00:00 PST Southeast Alaska is a remote area, located approximately 700 miles north of Seattle, Washington. Most of the region’s goods are imported by barge, creating logistical and economic challenges not faced by many other parts of the United States. In this context, we used life cycle assessment (LCA) to evaluate the potential environmental impact on global warming potential (GWP) of converting home heating systems from heating oil to wood pellets in southeast Alaska. Once the current level (status quo) was established, we evaluated imported pellet utilization at 20-, 40- and 100-percent penetration into the residential heating oil markets. We also modeled local production of wood pellets in southeast Alaska, assuming a 20-percent penetration. Our research found that reductions in GWP resulting from the conversion to wood pellets ranged from 10 to 51 percent, with the greatest reductions being associated with the highest levels of imported pellets. The scenario of producing wood pellets in southeast Alaska to meet local needs had a reduction in GWP of 14 percent (versus the status quo). Full Article
ia Historical Forest Structure, Composition, and Spatial Pattern in Dry Conifer Forests of the Western Blue Mountains, Oregon. By www.fs.fed.us Published On :: Thu, 16 Nov 2017 08:00:00 PST In frequent-fire forests of the interior Western United States, historical (prefire suppression) conditions are often used as a reference to set management objectives, guide prescriptions, and monitor treatment effectiveness. We quantified the historical size, density, composition, and spatial patterns of dry mixed-conifer forests in the Blue Mountains of Oregon to establish reference conditions that could be used for ongoing forest-restoration efforts.

ia Deep Canyon and Subalpine Riparian and Wetland Plant Associations of The Malheur, Umatilla, and Wallowa-Whitman National Forests By www.fs.fed.us Published On :: Thu, 09 Nov 2006 09:26:36 PST This guide presents a classification of the deep canyon and subalpine riparian and wetland vegetation types of the Malheur, Umatilla, and Wallowa-Whitman National Forests. A primary goal of the deep canyon and subalpine riparian and wetland classification was a seamless linkage with the midmontane northeastern Oregon riparian and wetland classification provided by Crowe and Clausnitzer in 1997. The classification is based on potential natural vegetation and follows directly from the plant association concept for riparian zones. The 95 vegetation types classified across the three national forests were organized into 16 vegetation series, and included some 45 vegetation types not previously classified for northeastern Oregon subalpine and deep canyon riparian and wetland environments. The riparian and wetland vegetation types developed for this guide were compared floristically and environmentally to riparian and wetland classifications in neighboring geographic regions. For each vegetation type, a section was included describing the occurrence#40;s#41; of the same or floristically similar vegetation types found in riparian and wetland classifications developed for neighboring geographic regions. Lastly, this guide was designed to be used in conjunction with the midmontane guide to provide a comprehensive look at the riparian and wetland vegetation of northeastern Oregon. Full Article
ia Variation In Shrub and Herb Cover and Production On Ungrazed Pine and Sagebrush Sites In Eastern Oregon: A 27-Year Photomonitoring Study By www.fs.fed.us Published On :: Fri, 30 Mar 2007 09:30:00 PST Study objectives were to evaluate yearly fluctuations in herbage canopy cover and production to aid in defining characteristics of range condition guides. Sites are located in the forested Blue Mountains of central Oregon. They were selected from those used to develop range condition guides where soil, topographic, and vegetation parameters were measured as a characterization of best range condition. Plant community dominants were ponderosa pine/pinegrass, ponderosa pine/bitterbrush/Idaho fescue savanna, low sagebrush/bluebunch wheatgrass, and rigid sagebrush scabland. None of the sites were grazed during the previous 30 years or during the 27-year study. Each location was permanently marked by fence posts, and a meter board was placed 10 m down an established transect line. Photographs (color slides) were taken down the transect with closeups left and right of the meter board. Sampling was limited to August 1-4 each year when canopy cover and herbage production were determined. Both total canopy cover and herbage production varied by about a 2.4-fold difference on each site over the 27 years. Apparently "good range condition" may be something of a "running target" and lacks a well-defined set of parameters. Canopy cover is a poor parameter for characterizing range condition. Three of the four plant communities were dominated by bunchgrasses. Abundance of seedheads is commonly used to indicate good range health. But on these sites, seedheads were not produced about half the time. Because these sites were in "good range condition," lack of seedhead production may indicate maximum competition in the community. Maximum competition and maximum vigor do not seem to be synonymous. These bunchgrass communities varied in their greenness on the first of August each year from cured brown to rather vibrant green suggesting important annual differences in phenology. The pinegrass community, being dominated by rhizomatous species, showed surprising variance in seedhead production. Pinegrass did not flower, but Wheeler's bluegrass, lupine, and Scouler's woolyweed were quite variable, averaging inflorescences only 75 percent of the time. Full Article
ia A Social History of Wild Huckleberry Harvesting In The Pacific Northwest By www.fs.fed.us Published On :: Thu, 23 Mar 2006 15:25:36 PST 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 Pacific Northwest 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.

ia The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management By www.fs.fed.us Published On :: Wed, 05 Apr 2006 15:25:36 PST The Pacific Northwest Research Station 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 information product needs of clients, as well as preferred technology transfer methods, and we discuss the future direction of the Biodiversity Initiative. Full Article
