FY2011Aspen populations are in decline across western North America due to altered fire regimes, herbivory, drought, pathogens, and competition with conifers. Aspen stands typically support higher avian biodiversity than surrounding habitats, and maintaining current distributions of several avian species is likely tied to persistence of aspen on the landscape. We are examining effects of climate change on aspen and associated avian communities in isolated mountain ranges of the northern Great Basin, by coupling empirical models of avian-habitat relationships with spatially-explicit landscape simulations of vegetation and disturbance dynamics (using LANDIS-II) under various climate change scenarios. We are addressing...

The Star Valley Front project was brought up by the Wyoming Game and Fish Department in the early 80's to help improve big game winter ranges. The project area contains mountain shrubland, big sagebrush, and aspen communities that are in less-than-suitable condition. The commumnities continue to decline due in large part to an over-representation of late-seral conditions and an insufficient frequency and extent of fire. Declining habitat conditions in the Star Valley Front project area are having negative effects on mule deer, elk, and moose due to declining forage conditions. Other wildlife species, including several migratory bird species, are being adversely impacted by the loss and decline in quality of mountain...
