Populations of many cold-water aquatic species are likely to decline this century with climate change, but declines will vary spatially. Some populations will be able to persist even under extreme climate change scenarios. Especially cold habitats could provide important refugia from both future environmental change and invasions by non-native species that prefer warmer waters.

The Climate Shield website hosts geospatial data and related information on specific locations of cold-water refuge streams for native cutthroat trout and bull trout across the northwestern United States. Forecasts about the locations of refugia could enable the protection of key watersheds, be used to rally support among multiple stakeholders, and provide a foundation for planning climate-smart conservation networks that improve the odds of preserving native trout populations through the 21st century.

Climate Shield was inspired by the landscapes of the Rocky Mountains and people everywhere that are working to preserve native trout. The Northern Rockies Adaptation Partnership provided a valuable forum that accelerated this work. The Great Northern and North Pacific Landscape Conservation Cooperatives generously funded the NorWeST project, which serves as the foundation for Climate Shield.

Approach

While a major goal of this project is to provide climate vulnerability and native trout refuge information to land managers and policymakers, another goal is to provide open access to the information through a common digital database and project website so that it can be accessed and used by anyone concerned about native trout in the region. The techniques and technology used to build Climate Shield are broadly applicable to other species and geographic areas and have shifted the paradigm of how natural resources research can be conducted.

“The high-resolution digital information from the study is the perfect complement to local knowledge, because it provides strategic maps that allow managers to put each stream in a broader context and make ‘apples to apples’ comparisons across landscapes in the northwest,” said RMRS investigator Dan Isaak.
