Revised Bull Trout Climate Shield Model

Isaak et al. (2022) published a revised Climate Shield model for juvenile bull trout that provides stream-specific probabilistic predictions about occurrence within 991 natal habitat patches across Montana, Idaho, and eastern Oregon. The model is more accurate than the original Climate Shield model and was used in 16 scenarios to assess the effects of habitat restoration and brook trout removals on improving population resilience under three climatic conditions (baseline, moderate change, and extreme change). That information is available from the table below as digital maps (.pdf files) and ArcGIS shapefiles. Please refer to this ReadMe document for descriptions of the scenarios and the Isaak et al. 2022 publication for additional details.
