U.S. Geological Survey, SOUTHWEST REGIONUnderstanding how climate change will contribute to ongoing declines in sagebrush ecological integrity is critical for informing natural resource management. We assessed potential future changes in sagebrush ecological integrity (SEI) under a range of scenarios using an individual plant-based simulation model, integrated with remotely sensed estimates of current sagebrush ecological integrity. The simulation model allowed us to estimate how climate change, wildfire, and invasive annuals interact to alter the potential abundance of key plant functional types that influence sagebrush ecological integrity: sagebrush, perennial grasses, and annual grasses. This layer shows the median projected change in SEI class (i.e., Core Sagebrush Area, Growth Opportunity Area, Other Rangeland Area) under representative concentration pathway (RCP) 4.5 for 2071-2100. The future (i.e., 2071-2100) median projected SEI class was calculated as the pixel-wise median across results from 13 Global Climate Models. Change in SEI class, is relative to the SEI class during 2017-2020 time-period. Please see Holdrege et al. 2024 (https://doi.org/10.1016/j.rama.2024.08.003) for details on our methods (note that this layer is shown in Fig 1a of that manuscript).
