We revised distribution maps of potential presettlement habitat and current populations for Greater Sage-Grouse (Centrocercus urophasianus) and Gunnison Sage- Grouse (C. minimus) in North America. Areas excluded from the revised maps were those dominated by barren, alpine, and forest habitats. The resulting presettlement distribution of potential habitat for Greater Sage-Grouse encompassed 1,200,483 km2, with the species' current range 668,412 km2. The distribution of potential Gunnison Sage-Grouse habitat encompassed 46,521 km2, with the current range 4,787 km2. The differences between the potential resettlement and current distributions appear related to habitat alteration and degradation, including the adverse effects of cultivation, fragmentation, reduction of sagebrush and native herbaceous over, development, introduction and expansion of invasive plant species, encroachment by trees, and issues related to livestock grazing.
