The Nisqually River Delta represents the largest wetland restoration in the Pacific Northwest. The restoration resulted in a 50% increase in potential salt marsh habitat. The Delta supports threatened salmon fisheries, large populations of migratory birds, and provides unique opportunities for recreation. The Delta also provides multiple ecosystem services, which are the benefits that wildlife or ecosystems provide to people. Development and changing climate patterns threaten to alter the Delta and the ecosystem services it provides. This study aims to quantify the value of existing and potential future ecosystem services from the Delta and provide insight into the vulnerability of the mosaic of habitats that support...

In the Northern Rockies, the annual area burned by wildfires has risen sharply in recent decades and is expected to continue growing. As a result, burned forests increasingly comprise a significant portion of the land base. However, burned areas represent a difficult paradox for land managers, especially in the context of other climate-linked disturbances (e.g., droughts, bark beetle outbreaks) that are also on the rise and may compound initial fire-induced stressors. While, burned areas have experienced major recent changes that may decrease their resilience to subsequent, compounding stressors, fire-induced changes can also lead to longer-term increases in resilience. The evolving landscape conditions triggered...

As freshwater streams and native fish are threatened by changing environmental conditions, efforts to coalesce existing data and integrate modeling and projection tools are increasingly necessary for informing effective land, water, and species management. For example, identifying and integrating disparate datasets of streamflow, stream water temperature and species distribution is critical for development of statistical models that inform comprehensive, multi-species climate vulnerability assessments to help managers plan for the future. Regional assessments of the vulnerability of native fishes to climate change in the Pacific Northwest have focused almost exclusively on salmonids (a family of fish that includes...

Aspen forests are considered keystone ecosystems, meaning that loss of aspen habitat would result in negative impacts to numerous plant and animal species. Aspen also provide important economic and social benefits, including drawing tourists, serving as potential fire breaks, improving local economies, and providing forage for wildlife and livestock. Ecologically-valuable aspen forests are considered at risk in many areas of the western U.S., but especially in lower-elevation areas. Risks to aspen include climate-change and past land use. The effects of drought and browsing animals (that eat young aspen) are often more severe for lower-elevation aspen and can threaten aspen forest health and long-term persistence....

Downed wood on the forest floor does more than provide habitat for amphibians, reptiles, birds and mammals. These decomposing habitat structures modify the temperature and moisture conditions in the forest itself. Inside and around downed wood, local climate conditions, or microclimates, provide wildlife with stable habitats that allow for persistence during and after wildfires. Cooler, wetter microclimates buffer the effects of wildfire in Oregon’s forests, making microclimate an important component of forest management. Despite the significance of downed wood to forest ecosystem function, forest management practices require only two downed logs to be retained for every acre harvested. To better inform forest management...

Managing species and habitat in a changing climate requires locally specific information about expected changes in the physical environment, key stressors and related ecological changes. Federal investments have supported the development of a significant scientific knowledge base detailing potential future conditions for many Northwest ecosystem types and geographies. Yet scientists, managers and other decision makers continue to be challenged by the difficulty of efficiently assessing the current state of understanding regarding both impacts and pathways for adaptation. For example, while the most recent Washington and Oregon State Wildlife Action Plans included detailed consideration of climate change-related...
