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...

The Northwest and North Central Climate Adaptation Science Centers (NW and NC CASCs) work in partnership with regional natural resource management communities to provide high priority science information and products needed for climate adaptation. In parallel with the U.S. Fish and Wildlife Service (USFWS) Region 6, the NW and NC CASCs prioritize science to inform sagebrush steppe and grassland ecosystem conservation, emphasizing the application of climate adaptation strategies that support at-risk populations and human-ecological communities within these ecosystems. To improve their ability to deliver effective and actionable science, the NW and NC CASCs must continually engage with regional partners and stakeholders...

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...

Climate change is altering the patterns and characteristics of fire across natural systems in the United States. Resource managers in the Northwest are faced with making natural resource and fire management decisions now, despite a lack of accessible information about how those decisions will play out as fire regimes, and ecosystem responses, will change across the landscape. Decision makers in natural-resource management increasingly require information about projected future changes in fire regimes to effectively prepare for and adapt to climate change impacts. An accessible and forward-looking summary of what we know about the “future of fire” is urgently required in the Northwest and across the country to support...

Climate change impacts on forests, including drought and wildfire, are of increasing concern to managers, conservationists, researchers, and culture bearers in the Pacific Northwest. Warmer temperatures exacerbate forest stress by accelerating evaporation and drying-out of the land surface and vegetation. These hotter drought conditions have been implicated in recent tree mortality events regionally and across the globe. Managers need science-based tools to assess risks posed by droughts, heat waves, and other climate-induced stressors, as well as practical solutions for adapting current management practices. The realities of climate change have spurred interest in tailoring silvicultural practices to increase forest...

Abundant scientific research has characterized the relationships between climate and fire in ecosystems of the United States, and there is substantial evidence that the role of fire in ecosystems is likely to change with a changing climate. Changing fire patterns pose numerous natural resource management challenges and decision makers in natural-resource management increasingly require information about potential future changes in fire regimes to effectively prepare for and adapt to climate change impacts. An effective forward-looking fire science synthesis is urgently required to reflect the changing dimensions of human fire management, recognizing that fire causes, effects, impacts, and management are all interrelated...

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...
