. 2012. Natural and cultural history of beargrass (Xerophyllum tenax). Gen. Tech. Rep. PNW-GTR-864. Portland, OR: U.S Department of Agriculture, Forest Service,Pacific Northwest Research Station. 80 p.

Forest managers are seeking practical guidance on how to adapt their current practices and, if necessary, their management goals, in response to climate change. Science-management collaboration was initiated on national forests in eastern Washington where resource managers showed a keen interest in science-based options for adapting to climate change at a 2-day workshop. Scientists and managers reviewed current climate change science and identified resources vulnerable to expected climate change. Vulnerabilities related to vegetation and habitat management included potential reductions in forest biodiversity and low forest resilience to changing disturbance regimes. The vulnerabilities related to aquatic and infrastructure resources included changing water quality and quantity, the risk to roads and other facilities from changes to hydrologic regimes, and the potential loss of at-risk aquatic species and habitats. Managers then worked in facilitated groups to identify adaptations that could be implemented through management and planning to reduce the vulnerability of key resources to climate change. The identified adaptations were grouped under two major headings: Increasing Ecological Resiliency to Climate Change, and Increasing Social and Economic Resiliency to Climate Change. The information generated from the science-management collaborative represents an initial and important step in identifying and prioritizing tangible steps to address climate change in forest management. Next would be the development of detailed implementation strategies that address the identified management adaptations..

The Pacific Northwest Research Station's Biodiversity Initiative: Collaborating For Biodiversity Management

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.

Integrated Research In Natural Resources: The Key Role of Problem Framing

Integrated research is about achieving holistic understanding of complex biophysical and social issues and problems. It is driven by the need to improve understanding about such systems and to improve resource management by using the results of integrated research processes. Traditional research tends to fragment complex problems, focusing more on the pieces of problems rather than the whole that comprises multiple interrelationships and interactions. The outcome is that a lot is known about the parts (e.g., recreation, fish, and wildlife) but relatively little about how they are interrelated. There seems to be general agreement that integrated questions must drive the search for integrated understanding, but tradition, inertia, institutional culture,budgets, training, and lack of effective leadership foster reductionism (at worst) or minimal degrees of integration (at best) rather than any substantial, sustainable effort toward integrated research. In this paper, a phased approach to framing integrated research questions and addressing the substantial barriers that impede integrated efforts are discussed. A key conclusion is that to make any significant progress toward comprehensive integrated research will require more than rhetoric. Progress must begin with more effective leadership throughout various levels of research organizations.

Market Opportunities For Kitchen Cabinets Made From Alaska Hardwoods: A Synthesis and Review of Recent Research

The kitchen cabinet industry has shown significant growth recently, with expanding residential markets, new cabinet styles, and larger kitchens. This industry represents an opportunity for small Alaska wood producers to create high-value secondary products. In response to recent trends in kitchen cabinet manufacturing and the need to identify opportunities for underutilized species, the Alaska Wood Utilization Research and Development Center has conducted numerous studies evaluating consumer preferences for Alaska's primary hardwoods-Alaska birch (Betula papyrifera var. humilis )Reg.) Fern & Raup) and red alder (Alnus rubra Bong.). These studies explored consumer preferences under a range of marketing parameters, cabinet appearances, and regional market locations. This paper summarizes these studies and offers insights into the potential market for Alaska's hardwoods as secondary wood products such as kitchen cabinets.

Potential vegetation hierarchy for the Blue Mountains section of northeastern Oregon, southeastern Washington, and westcentral Idaho

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).

Silvicultural research and the evolution of forest practices in the Douglas-fir region

Silvicultural practices in the Douglas-fir region evolved through a combination of formal research, observation, and practical experience of forest managers and silviculturists, and changing economic and social factors. This process began more than a century ago and still continues. It has had a great influence on the economic well-being of the region and on the present characteristics of the region's forests. This long history is unknown to most of the public, and much of it is unfamiliar to many natural resource specialists outside (and even within) the field of silviculture. We trace the history of how we got where we are today and the contribution of silvicultural research to the evolution of forest practices. We give special attention to the large body of information developed in the first half of the past century that is becoming increasingly unfamiliar to both operational foresters and--perhaps more importantly--to those engaged in forestry research. We also discuss some current trends in silviculture and silviculture-related research.

Understanding concepts of place in recreation research and management

Over a 3-day weekend in the spring of 2004 a group of scientists interested in extending understanding of place as applied in recreation research and management convened a working session in Portland, Oregon. The purpose of the gathering was to clarify their understanding of place-related concepts, approaches to the study of people-place relations, and the application of that understanding in recreation management for the purpose of integrating perspectives from different disciplines, discussing approaches to understanding and measuring sense of place, and other questions around the study and application of place-related concepts. Topics that generated the most discussion included how social processes influence place meanings, how place meanings are shared and negoitated within social groups, and when and how place meanings and attachments focus, reduce, or avert conflict in natural resource planning and management. This collection of papers is a result of that meeting.

Soils under fire: soils research and the Joint Fire Science Program

Soils are fundamental to a healthy and functioning ecosystem. Therefore, forest land managers can greatly benefit from a more thorough understanding of the ecological impacts of fire and fuel management activities on the vital services soils provide. We present a summary of new research on fire effects and soils made possible through the Joint Fire Science Program and highlight management implications where applicable. Some responses were consistent across sites, whereas others were unique and may not easily be extrapolated to other sites. Selected findings include (1) postfire soil water repellency is most likely to occur in areas of high burn severity and is closely related to surface vegetation; (2) although wildfire has the potential to decrease the amount of carbon stored in soils, major changes in land use, such as conversion from forest to grasslands, present a much greater threat to carbon storage; (3) prescribed fires, which tend to burn less severely than wildfires and oftentimes have minor effects on soils, may nonetheless decrease species richness of certain types of fungi; and (4) early season prescribed burns tend to have less impact than late season burns on soil organisms, soil carbon, and other soil properties.

The Western Bark Beetle Research Group: a unique collaboration with Forest Health Protection--proceedings of a symposium at the 2007 Society of American Foresters conference

The compilation of papers in this proceedings is based on a symposium sponsored by the Insect and Diseases Working Group (D5) at the 2007 Society of American Foresters (SAF) convention in Portland, Oregon. The selection of topics parallels the research priorities of the Western Bark Beetle Research Group (WBBRG) (USDA Forest Service, Research and Development), which had been recently formed at the time of the symposium. Reflecting a unique partnership within the Forest Service, each paper was jointly prepared by a research scientist with the WBBRG and one or more entomologists with Forest Health Protection (USDA Forest Service, State and Private Forestry). Among these papers is a description of the currently elevated impacts of bark beetles in the Western United States; descriptions of the current state of knowledge of bark beetle response to vegetation management and also to climate change; discussions of the complex interactions of bark beetles and fire and of the complex ecological and socioeconomic impacts of infestations; an overview of the use of semiochemical (behavioral chemicals)-based technology for conifer protection; and a case study exemplifying efforts to assess risks posed by nonnative invasive bark beetles.

ArcFuels10 system overview

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.
