Cheatgrass

The USGS Cheatgrass dataset provides annual fractional percent cover estimates of cheatgrass (Bromus tectorum) across the western United States sagebrush biome at 30m resolution. Estimates are derived from Harmonized Landsat and Sentinel-2 imagery and field observations. USGS replaced this dataset with RCMAP-EAG in 2026, and it is no longer updated (last data: 2024). Use Cheatgrass (RCMAP) for current data.
