Early Estimates of Exotic Annual Grass (EAG) in the Sagebrush Biome, USA, 2025 (ver. 1.0, April 2025)

These datasets provide early estimates of 2025 fractional cover for exotic annual grass (EAG) species and one native perennial grass species on a weekly basis from mid April to late June. Typically, the EAG estimates are publicly released within 7-13 days of the latest satellite observation used for that version. Each weekly release contains five fractional cover maps along with their corresponding confidence maps for: 1) a group of 16 species of EAGs, 2) Cheatgrass (Bromus tectorum); 3) Field brome (Bromus arvensis); 4) Medusahead (Taeniatherum caput-medusae); and 5) Sandberg bluegrass (Poa secunda). These datasets were generated leveraging field observations from Bureau of Land Management (BLM) Assessment, Inventory, and Monitoring [...]
