In the Pacific Northwest, land and resource managers strive to make decisions that benefit both natural and human communities, balancing ecological and economic demands including wildlife habitat, forest products, forage for grazing, clean water, and wildfire control. Climate change adds a layer of complexity to the planning process because of its uncertain effects on the environment. In order to make sound decisions, managers need information about how climate change will affect wildlife habitat, both on its own and in conjunction with management actions. The goal of this project was to explore how future climate may interact with management alternatives to shape wildlife habitat across large landscapes. Scientists...

Whitebark pine is a high-elevation, important tree species that provides critical habitat for wildlife and supplies valued ecosystem services. These trees currently face multiple threats, including attack by the mountain pine beetle, which has recently killed whitebark pines over much of the western U.S. Climate is an important factor in these outbreaks, and future warming is expected to affect epidemics. Our project developed statistical models of outbreaks in whitebark pine for three regions: the Greater Yellowstone Ecosystem, the Northern U.S. Rocky Mountains, and the Cascade Range. We used these models to understand climate/beetle outbreak relationships, evaluate climatic causes of recent outbreaks, and estimate...

Greater sage-grouse (Centrocercus urophasianus) is a candidate for listing under the Endangered Species Act because of population and habitat fragmentation combined with inadequate regulatory mechanisms to control development in critical areas. In addition to the current threats to habitat, each 1 degree celsius increase in temperature due to climate change is expected to result in an additional 87,000 km2 of sagebrush (Artemisia spp.) that will be converted to unsuitable habitat for sage-grouse. Thus, the future distribution and composition of sagebrush landscapes is likely to differ greatly from today’s configuration. We conducted a large, multi-objective project to identify: (1) characteristics of habitats required...

Climate responses of sagebrush are needed to inform land managers of the stability and restoration of sagebrush ecosystems, which are an important but threatened habitat type. We evaluated climate responses of sagebrush using two approaches: (1) experimental manipulations of temperature and precipitation for natural plants in the field, and (2) assessment of how climate adaptation and weather have affected sagebrush seeding efforts on nearly 25 large-scale sagebrush seeding projects done over the past several decades. Experimental warming increased growth of sagebrush in high-elevation meadows in the Teton Mountains, but had marginal or no effect at lower elevations sites (near Twin Falls and Boise, Idaho, respectively)....
