Columbian sharp-tailed grouse (Tympanuchus phasianellus columbianus) were historically found in shrub steppe, meadow steppe, steppe, and deciduous shrub communities throughout much of eastern Washington. The current range, consisting of 8 relatively small, isolated, populations, is less than 3% of historic range. Information collected since 1954 indicates 58% of 107 known lek complexes are currently vacant. Many of the vacant lek complexes (53%) are in areas where sharp-tailed grouse have been extirpated since 1954. Based on annual changes in number of birds counted on lek complexes, the number of sharp-tailed grouse in Washington declined by about 92% since 1954 to 858 birds in 1998. Historic and recent declines of sharp-tailed grouse appear linked to dramatic declines in quantity and quality of native habitat.
