Abstract: The Jackson Hole sage grouse population has experienced a 63% decline since 1995, based on maximum rooster counts on known leks. The current population is 400% below its peak in 1950, and is estimated at less than 175 individuals. The current population needs to increase by 133% to reach viable population levels. It is imperative that potential causative factors be investigated before this population is extirpated. A 3-year project funded by the Wyoming Game and Fish Department and the National Park Service examining seasonal habitat selection and survival of sage grouse in Grand Teton National Park was initiated in 1999. The project is concerned with identifying seasonal habitat inadequacies, important seasonal ranges, and seasonal survival throughout the park.
