Colorado sits at the extreme southeastern edge of greater sage-grouse's continental range, and the entire population is confined to the northwestern part of the state. CPW's own species account names seven distinct sub-populations: Northwest Colorado, North Park (roughly 20% of the statewide population on its own), Middle Park, Northern Eagle-Southern Routt, Parachute-Piceance-Roan (PPR), Meeker/White River, and Laramie River (a small population shared with adjoining Wyoming/southern-Laramie-River habitat). This matches the regulation's two-season GMU structure almost exactly: Season 2 covers North Park specifically, and Season 1 covers the rest of the GMUs spanning the other six populations. Birds generally occupy open sagebrush ridges, plateaus, and flats between 6,000-9,000 feet.
CPW conducts an active, 25+ year spring lek-count program across 500+ known leks in northwest Colorado, but no discrete standalone 2026 report or numeric count has been found. CPW's own species page's most recent cited figures date to 2016. No confirmed fixed publish window exists.
