Historically, sage-grouse occurred in at least 15 states and 3 provinces from British Columbia east to Saskatchewan and south to New Mexico and California. Presently they are found in 11 states and 2 provinces [27,99]. Sage-grouse have been translocated in New Mexico, Oregon, Montana, Wyoming, Utah, Colorado, Idaho and British Columbia. New Mexico initiated the earliest attempts at translocations in 1933 after the species was extirpated from the state in 1912. Efforts were unsuccessful. British Columbia attempted to reintroduce sage-grouse in 1958. No sage-grouse have been reported since 1966 and are considered to have been extirpated within the province [68,99]. In addition, sage-grouse have been extirpated in most of North and South Dakota, Nebraska, Kansas, Oklahoma, central California [60,64,68,87], and Arizona .
Greater sage-grouse are distributed from north-central Oregon, southern Idaho, and southern Alberta and Saskatchewan south to eastern California and extreme western North and South Dakota. Isolated populations also occur in eastern Washington [66,87,124]. Western sage-grouse occur only in eastern Washington and Oregon. The ranges of western and eastern sage-grouse overlap in Oregon. Eastern sage-grouse occur in all states and provinces within the range of sage-grouse except Washington [1,24].
Gunnison sage-grouse occur in 7 counties in southwestern Colorado and 1 county in southeastern Utah .
