Climate Shield ArcGIS Shapefiles

The Climate Shield models developed by Isaak et al. (2015) provide stream-specific rangewide probabilistic predictions about the occurrence of juvenile Bull Trout and Cutthroat Trout under different scenarios of climate change and Brook Trout invasions. More information is available at the Cold-Water Climate Shield project page as easy-to-use digital maps (.pdf files) and ArcGIS shapefiles for all streams within the historical ranges of these two native trout species across the western U.S.
