As temperature and precipitation patterns change, different species in different areas will be affected in different ways. Some places may serve as refuges for wildlife—places where animals can remain or to which they can easily move to escape the worst impacts of climate change. This project will establish a Refugia Research Coalition to leverage recently funded Northwest CASC research...

The impacts of climate change are already being observed and felt in our ecosystems and communities. Land and resource managers, planners, and decision-makers are looking for the best scientific information to guide their decisions about adapting to and mitigating the effects of climate change now and in the future. A major goal of the Northwest Climate Science Center (CSC) and the CSC...

Climate change, drought, habitat alterations, and increasing water demands are leaving less water available for streams of the Pacific Northwest and for fish like salmon. As water levels drop, some small streams become fragmented, transforming from a ribbon of continuous habitat into a series of isolated pools. Fragmented streams may pose a serious threat to salmon. For example...

Warmer temperatures and less precipitation in the western U.S. related to climate change are harming many important natural resources, including forests, rivers, and many fish and wildlife species. Climate refugia provide a potential opportunity for conserving resources and biodiversity in the face of climate change. These refugia are places where the climate will likely change less than...

Streams are classified as perennial (flowing uninterrupted, year-round) or intermittent (flowing part of the year) or ephemeral (flowing only during rainfall events). The classifications of “streamflow permanence” were primarily established in the middle 20th century and are often outdated and inaccurate today if they were not adjusted for changes in land use, wildfires, or climate...

Due to the ecological importance of stream temperature for aquatic species, and concern about rising temperatures associated with climate change, natural resource managers throughout the Pacific Northwest increasingly require locally detailed stream temperature information in order to effectively manage aquatic resources. Recent technological advances in stream temperature monitoring (e...

The Northwest Climate Conference (formerly called the Pacific Northwest Climate Science Conference) is the premier climate science event for the region, providing a forum for researchers and practitioners to share scientific results and discuss challenges and solutions related to the impacts of climate change on people, natural resources, and infrastructure in the Northwest.

In the Pacific Northwest, coastal ecosystems are highly productive areas that support millions of migratory waterbirds, shellfish, salmon and related fish. These species depend on food and habitats provided by estuaries (coastal tidal areas where streams and rivers flow into the ocean) for successful migration and breeding. Climate change effects such as drought, sea-level rise, and...

In the Pacific Northwest, cold-water species like salmon are important for recreational sport fishing as well as for commercial fish production. However, climate change is causing lower and warmer summer stream flows that could decimate these fish populations. Aquatic cold-water habitats are further threatened by stormwater runoff, which moves from streets to storm drains and then is...

Forests are of tremendous ecological and economic importance. They provide natural places for recreation, clean drinking water, and important habitats for fish and wildlife. However, the warmer temperatures and harsher droughts in the west that are related to climate change are causing die-offs of many trees. Outbreaks of insects, like the mountain pine beetle, that kill trees are also...

This project was designed to use the combined strengths of the cooperators to address their concerns stemming from the degradation of arid environments in the Great Basin. The project aimed to identify the regional ecological and social costs and benefits of both immediate hydrologic modifications (low-profile constructed dams) and longer-term restoration of beavers (Castor canadensis)...
