Species that inhabit the arid Southwest are adapted to living in hot, dry environments. Yet the increasing frequency and severity of drought in the region may create conditions that even these hardy species can’t survive. This project examined the impacts of drought in the southwestern U.S. on four of the region’s iconic species: desert bighorn sheep, American pronghorn, scaled quail, and Rio Grande cutthroat trout. Grasping the impacts of drought on fish and wildlife is critical for management planning in the Southwest, as climate models project warmer, drier conditions for the region in the future. Species are known to respond to environmental changes such as drought in different ways. Often, before changes...

The antelope-like pronghorn is the fastest land animal in North America and has the longest land migration in the continental U.S—in fact, the species has been dubbed “the true marathoners of the American West”. While pronghorns are numerous in parts of their range, such as Wyoming and northern Colorado, they are endangered in others, such as the Sonoran Desert. In the arid Southwest, pronghorn populations have been declining since the 1980s—and it’s thought that drought is partially to blame. Average temperatures in the Southwest have increased 1.6°C since 1901, and the area affected by drought from 2001-2010 was the second largest observed since 1901. Drought conditions have reduced the availability of vegetation,...

Native to the southwestern U.S. and northwestern Mexico, the desert bighorn sheep is known for its ability to adapt to harsh, arid environments. However, this does not mean the species is immune to the effects of drought. In fact, the fragmented and isolated distribution of the desert mountain ranges that they inhabit means that they can’t follow distant rain storms without traversing broad valleys at significant risk to mortality. This study examined the effects of a 2002 drought on desert bighorn sheep in the Cabeza Prieta National Wildlife Refuge in southwestern Arizona. Specifically, researchers explored how the drought may have affected habitat selection, behavior, and diet of the sheep. For example, when...
