Climate Change Vulnerability Assessment for the Upper Snake River Watershed
This collaborative vulnerability assessment expressly considered the species, habitats, and resources that are important and valuable to USRT member tribes. Climate change impacts on these resources have the potential to affect tribal members’ culture, spirituality, and lifeways.
The collaboration involved the direct and ongoing participation of USRT staff and the leadership, staff, and membership of the four member tribes. Combining the best available localized climate projections with traditional knowledge, tribal priorities, and local observations were central to the success of this assessment.
This vulnerability assessment included four steps:
- Analyzing downscaled temperature and precipitation projections for the project area;
- Site visits to USRT member tribes’ reservations to identify Shared Concerns;
- Use of the NatureServe Climate Change Vulnerability Index (CCVI) and other methods to determine relative vulnerability rankings; and
- A collaborative vulnerability assessment workshop in Boise with USRT member tribes’ staff and leadership.

Climate Change Projections
This project used downscaled climate data to generate projections for relevant climate parameters, such as temperature and precipitation. The colored domains in the figure below represent distinct climate zones and are outlined in red, yellow, and green. They blue line represents the Upper Snake River Watershed.
Below are Climate Projections for the YELLOW Domain of the Upper Snake River. Cli-mate variables presented include: average annual temperature (1950-2100), average annual precipitation (1950-2100), mean seasonal temperature (2040-2069), and mean seasonal precipitation (2040-2069). These climate variables are shown in their histori-cal amounts and in future scenarios, including: a greenhouse gas reduction scenario (RCP 4.5) and a “business as usual” greenhouse gas emission scenario (RCP 8.5).
