Agencies and organizations deploy various strategies in response to environmental challenges, including the formulation of policy, programs, and regulations. Citizen-based environmental stewardship is increasingly seen as an innovative and important approach to improving and conserving landscape health. A new research focus on the stewardship of urban natural resources is being launched by the U.S. Forest Service in the Pacific Northwest region. Early scoping efforts are addressing various scales of human systems ranging from individuals to organizations to the entire positive "footprint" of stewardship on the land. This report addresses a fundamental need—to understand and describe civic environmental stewardship in urban settings. Stewardship has been described and defined in diverse ways within a variety of contexts, including the philosophical literature of environmentalism, agency program descriptions, and outreach by sponsoring organizations. Constructing a framework to convey the layered meanings of stewardship will help to focus and guide future research. A cognitive mapping technique was used to elicit responses to the question "What is environmental stewardship?" Semistructured interviews were conducted with representatives of nine Seattle environmental organizations, a group of practitioners who collectively represent over 100 years of experience in the field. Program planners and managers have particularly direct experiences of stewardship. Cognitive mapping enables participants to explore, then display, their particular knowledge and perceptions about an idea or activity. Analysis generated thematic, structural representations of shared concepts. Results show that the practitioners have multilayered perceptions of stewardship, from environmental improvement to community building, and from actions to outcomes. The resulting conceptual framework demonstrates the full extent of stewardship activity and meaning, which can aid stewardship sponsors to improve stewardship programs, leading to better experiences for participants and higher quality outcomes for projects and environments.

We conducted an experimental study of infection, transmission, and persistence of a nucleopolyhedrovirus (NPV) of Douglas-fir tussock moth (Orgyia pseudotsugata) to better understand mechanisms determining the efficacy of the virus when it is used as a microbial control agent. In a field experiment, we quantified infection rates of larvae exposed to either Tussock Moth Biocontrol-1, the strain currently used for control by the U.S. Forest Service, or a wild-type strain isolated from a natural population. We first allowed each pathogen to decay on experimental branches for 0, 1, or 3 days before allowing uninfected larvae to feed on the branches, and then we fit both a generalized linear model and an epidemiological model of virus transmission to the infection data. Longer decay of the NPV resulted in lower infection rates, but evidence that overall virus transmission differed between wild and pesticide isolates of NPV was weak. The short persistence time of the virus suggests that it does not last long on foliage, in turn suggesting that application of TM Biocontrol-1 must be carefully timed to ensure maximum mortality.

Fungi are key players in the health, diversity, and productivity of forest ecosystems in Pacific Northwest forests, as mycorrhizal associations, pathogens, decomposers, nontimber resources, and food resources for wildlife. A number of invertebrate species are associated with wood decay fungi, serve as vectors for fungal pathogens, or are fungivorous (consume fungi) and influence rates of wood decay and nutrient mineralization. In Washington and Oregon, 31 wildlife species among 8 families are fungivores, and at least 14 wildlife species disperse fungi. Down wood can provide nurse substrates for seedlings and beneficial mycorrhizal fungi, refuges from pathogenic soil fungi, sources of nutrients for decay fungi, and substrates supporting overall fungal diversity. Presence, density, distribution, and diversity of fungi are influenced by forest stand management practices, forest age class, and effects of fire. Old forests provide for a suite of rare fungi species. Old legacy trees retained during forest harvest can provide some degree of conservation of beneficial and rare fungi. Fungi can be difficult to detect and monitor; surveying for fungi at various times of the year, for multiple (at least 5) years, and by including hypogeous (belowground) samples, can improve detection rates. Studies are needed in the Pacific Northwest to quantify the amount of down wood—number of pieces, sizes, total biomass, percentage of forest floor cover, and other attributes—necessary for maintaining or restoring fungal biodiversity and viable levels of individual fungi species, especially rare species.

The Silvies Valley Ranch is an example of using local innovation to combat the global problem of incised streams on rangelands. Incised channels reduce the flow between water in the channel and water in the surrounding soils, which reduces the vegetation available for wildlife habitat and cattle forage. One of the ranch owners, Scott Campbell, a doctor of veterinary medicine, believes that stream incision is related to the decline of beaver populations; thus, the ranch’s approach to restoration includes efforts to mimic beavers’ influence on the system. He is using an extensive network of low-rise dams made from locally available materials (dirt, gravel, rock, and logs), commonly referred to as “artificial beaver dams” (ABDs). Campbell said that the ABDs on the ranch successfully increased stream connectivity to their floodplains and increased the quantity and forage quality of wet meadows on the property, with no changes in where cattle were grazing. The experiences of this landowner exemplify a unique approach that provides a model for others facing similar challenges to doing restoration on private land. The transformation taking place on the Silvies Valley Ranch has garnered the attention of neighboring ranch owners, some of whom are beginning to experiment with similar restoration technologies. Campbell would like to continue installing structures, but has encountered numerous roadblocks in the permitting process. He has since taken an active role in building legislative support for the ABD technology being used on the ranch, and in facilitating its adoption in other places. This case study—based on interviews with stakeholders involved in the Silvies Valley Ranch project—highlights the social benefits and challenges experienced by one rancher using ABDs as a restoration tool, and provides insights for improving their use in the future. It is part of a larger interdisciplinary study that explores the potential of different beaver-related restoration approaches for achieving watershed restoration and livestock production goals on rangelands in the Western United States.

Since 1960, the Forest Service has been guided by the multiple-use concept, which recognizes five major uses for public lands-timber, water, range, recreation, and fish and wildlife habitat-and mandates that all five should be equally considered in management plans.

Effectively addressing wildfire risk to communities on large multi-owner landscapes requires an understanding of the biophysical factors that influence risk, such as fuel loads, topography, and weather, and social factors such as the capacity and willingness for communities to engage in fire-mitigation activities.

Alaska’s Arctic tundra is one of the most rapidly warming regions in the world. For years, scientists have been working to interpret the effects of its changing climate and determine what these changes may mean for the rest of the planet. Coarse-scale satellite imagery of much of this region shows the tundra is becoming greener. This has been widely attributed to shrub expansion.

Increasing the population of spring Chinook salmon and summer steelhead in Washington state’s Methow River is a goal of the Upper Columbia Spring Chinook Salmon and Steelhead Recovery Plan. Spring Chinook salmon and summer steelhead are listed as endangered and threatened, respectively, under the Endangered Species Act.
