Abstract: Sagebrush (Artemisia spp.) burning and predator control practices are currently performed in many areas also used by sage grouse (Centrocercus urophasianus). The objectives of this study were to document the effects of these habitat and species manipulations on a sage grouse population found near Kemmerer, Wyoming. Using radio-collared sage grouse hens and field observations of the birds, we identified and quantified sage grouse habitats (vegetative characteristics) and population dynamics (nest initiation, nest success, survival, distribution, etc.). A number of burns of various size and age in close proximity to grouse leks provided us with the opportunity to investigate the long-term effects of burning to sage grouse and their habitat. In addition, we also examined the effects of predator removal (performed for local sheep operations) on the abundance and composition of predator species and the nest success of sage grouse. Our results enable us to make management recommendations for the maintenance of crucial seasonal habitat for sage grouse and to provide insights into the effects of habitat manipulation and predator control on the local sage grouse population.
