Book Description
During the 20th century, Greater Sage-Grouse (Centrocercus urophasianus) populations in North America have declined by 69-99%. In southwest Montana little is known about the factors leading to declines in sage grouse populations; as a result, there are strong concerns regarding sage grouse population trends and habitat quality. I used radio-marked male sage grouse to obtain known-fate survival data and provide locations for habitat analyses. The objectives of the study were (1) to estimate survival rates of marked birds, and (2) to characterize the habitat used by sage grouse in southwestern Montana and compare it with available habitat. I used known-fate data to estimate annual survival, and I measured habitat attributes associated with aerial locations of instrumented sage grouse (use sites) and a series of randomly chosen locations within each study site (available sites).
