Populations of greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) have been declining range-wide for the last century (Connelly et al. 2004). The range of sage-grouse has declined from a historical pre-settlement distribution of 1.2 million square km to only 668,000 square km as of the year 2000 (Schroeder et al. 2004).
