Production of high-quality water is a vitally important ecosystem service in the largely semiarid interior Columbia River basin (ICRB).

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.

National forests and grasslands are home to a diverse array of wildlife.

The Chugach and Tongass National Forests are changing, possibly in response to global warming.

Trees bursting forth with new leaves signal the arrival of spring. Budburst for most temperate tree species occurs after a tree has been exposed to a sufficient number of chilling and forcing hours over the winter.

Earth's climate is changing, as evidenced by warming temperatures, increased temperature variability, fluctuating precipitation patterns, and climate-related environmental disturbances.

Sustainable working landscapes are critical to the conservation of biodiversity in the American West and its cultures of rural ranching and forestry.

Higher global temperatures are changing ecosystems in the Arctic. They are becoming greener as the climate and land become more hospitable to taller vegetation.

Much of the water supply in the Pacific Northwest originates in national forests. It sustains the region’s aquatic ecosystems, agriculture, hydroelectric power, and community water supplies.

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.

Mount St. Helens' explosive eruption on May 18, 1980, was a pivotal moment in the field of disturbance ecology.

Land use and climate change are two key factors with the potential to affect stream conditions and fish habitat. Since the 1950s, Washington and Oregon have required forest practices designed to mitigate the effects of timber harvest on streams and fish.

Societies use biologically active chemicals as medicines and pesticides to protect human and agricultural health. But widespread use of synthetic compounds raises concerns about their safety, and resistance development in targeted pests.

As a signatory to the United Nations Framework Convention on Climate Change, the United States annually compiles a report on the nation's carbon flux—the amount of carbon emitted into the atmosphere compared to the amount stored by terrestrial landscapes.

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.

Landscape exposure to multiple stressors can pose risks to human health, biodiversity, and ecosystem services. Attempts to study, control, or mitigate these stressors can strain public and private budgets. An interdisciplinary team of Pacific Northwest Research Station and Oregon State University scientists created maps of the conterminous United States that indicate landscape exposure to concentrated wildfire potential, insects and disease risk, urban and exurban development, and climate change. The maps, which show where these stressors might occur and overlap, provide a valuable resource for regional and national land use, land management, and policymaking efforts by helping to guide resource prioritization.

In the Pacific Northwest, native salmon and trout are some of the toughest survivors on the block. Over time, these fish have evolved behavioral adaptations to natural disturbances, and they rely on these disturbances to deliver coarse sediment and wood that become complex stream habitat. Powerful disturbances such as wildfire, postfire landslides, and debris flows may be detrimental to fish populations in the short term, but over time, they enrich instream habitats, enhancing long-term fish survival and productivity.

Woodpeckers and other cavity-excavating birds worldwide are keystone species. These birds excavate their nests out of solid wood, and because their nests are often well protected against predators and the environment, other species use and compete for their old, vacant nests. The presence of cavity-excavating birds in forests has far-reaching effects on species richness and ecosystem health.

Interest in landscape-scale approaches to fire management and forest restoration is growing with the realization that these approaches are critical to maintaining healthy forests and protecting nearby communities. However, coordinated planning and action across multiple ownerships have been elusive because of differing goals and forest management styles among landowners. Scientists with the Pacific Northwest Research Station and their colleagues recognized that working at the landscape scale requires integrating the biophysical, social, and economic dimensions of the problem, and this necessitates collecting new types of information and inventing new tools.

With the passage of the Multiple Use Sustained Yield Act of 1960, the U.S. Forest Service has managed its 193 million acres of forest and grassland for multiple uses, including timber, watersheds, and wildlife. Using today’s terminology, some of these purposes are considered ecosystem services, which encompass a breadth of benefits provided by forests, including their ability to absorb and store atmospheric carbon, a greenhouse gas linked to climate change.

A balanced diet and regular exercise are fundamental for good health, and a daily dose of nature may be equally important. Nearly 40 years of research has demonstrated that “metro nature”—nature found in urban environments, such as parks or tree-lined streets—provides positive and measurable health benefits and improves people’s quality of life.

Resource managers have long mapped biophysical forest data. Often lacking, however, is relevant social science data for understanding the variety of human needs a given landscape fulfills.

Air quality is a critical issue affecting the health of billions of people worldwide, yet often little is known about what is in the air we breathe. To reduce air pollution’s health impacts, pollution sources must first be reliably identified. Otherwise, it is impossible to design and effectively enforce environmental standards. However, urban networks of air quality monitors are often too widely spaced to identify the sources of air pollutants, especially for pollutants that do not disperse far from their sources. Developing high-resolution pollution maps with data from these widely spaced monitors is problematic.

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.

Although burned trees are the most visible damage following a wildfire, a forest’s soil can also be damaged. The heat generated by a wildfire can alter the soil’s physical properties and kill the fungi and bacteria that are responsible for nutrient cycling and other ecosystem services. What isn’t well understood is the extent of the heating within the soil and how quickly the soil recovers.

Millions of people head to federal lands every year for recreation—891 million visits in 2016 alone. These visits have significant economic implications, not only for restaurants, resorts, outfitters, and other businesses near recreation sites, but also for the people actually participating in outdoor recreation.

Accurate measurements of natural resources are a prerequisite for resource assessment. Demetrios Gatziolis, a scientist with the USDA Forest Service Pacific Northwest Research Station, and his colleagues with Washington State University developed and tested protocols for using structure-from-motion photogrammetry to obtain data that can be used to construct 3-dimensional (3-D) representations of trees, other vegetation, and down wood. This type of photogrammetry is a remote-sensing technique based on a sequence of digital images or video footage. Gatziolis and his colleagues focused on developing protocols for using it under the forest canopy. Their method can serve as a guide for others interested in obtaining inexpensive, precise 3-D data of trees in field plots. The researchers continue to perfect the technology so it can be reliably deployed by field crews with a minimal amount of training.

Diameter growth is seasonal in Douglas-fir, the evergreen tree found in much of western Washington, Oregon, and northern California. Initiation and cessation of diameter growth are both triggered by environmental cues. The tree responds to these cues to improve its chances of growing under favorable conditions. As environmental conditions change, however, land managers want to know how warmer summers and falls may affect diameter growth in Douglas-fir.

Wildfires consume existing forest fuels but also leave behind dead shrubs and trees that become fuel to future wildfires. Harvesting firekilled trees is sometimes proposed as an economical approach for reducing future fuels and wildfire severity. Postfire logging, however, is controversial. Some question its fuel reduction benefits and its ecological impacts.

The marbled murrelet (Brachyramphus marmoratus) is a threatened coastal bird that feeds on fish and nests in old-growth forests. In northwest Washington, murrelet populations are declining despite protections provided by the Northwest Forest Plan.

Principal findings of the National Fire and Fire Surrogate (FFS) study are presented in an annotated bibliography and summarized in tabular form by site, discipline (ecosystem component), treatment type, and major theme. Composed of 12 sites, the FFS is a comprehensive multidisciplinary experiment designed to evaluate the costs and ecological consequences of alternative fuel reduction treatments in seasonally dry forests of the United States. The FFS has a common experimental design across the 12-site network, with each site a fully replicated experiment that compares four treatments: prescribed fi re, mechanical treatments, mechanical + prescribed fire, and an unmanipulated control. We measured treatment cost and variables within several components of the ecosystem, including vegetation, the fuel bed, soils, bark beetles, tree diseases, and wildlife in the same 10-ha experimental units. This design allowed us to assemble a fairly comprehensive picture of ecosystem response to treatment at the site scale, and to compare treatment response across a wide variety of conditions.

This publication describes the bird communities of major mainland rivers of southeast Alaska and is based on a review of all known relevant studies as well as recent fieldwork. We synthesized information on the composition, structure, and habitat relationships of bird communities at 11 major mainland rivers. Information on current management concerns and research needs are also included.
