Long-term Changes in Environmental Characteristics Required by Sage-grouse Predicted under Climate Change

Sagebrush (Artemisia spp.)-dominated shrublands are one of the most widespread ecosystems in western North America but also among the most imperiled due to interactions among land use, fire, and exotic plants. Global climate change models predict an accelerated loss of sagebrush due to synergistic feedbacks among disturbance patterns and vegetation response; only 20% would remain under the most extreme scenario of >6 C increase by the end of this century (Fig. 1). Much of the current sagebrush distribution within the Great Northern Landscape Conservation Cooperative (GNLCC) would be lost. The conservation status of Greater sage-grouse (Centrocercus urophasianus), the most visible of >350 plant and wildlife species...
