Drought

Droughts of the future will be hotter, longer-lasting, and larger than droughts of the past. CASC-supported scientists are working to understand how changing drought conditions will impact important natural resources. Learn more about this work below.

The Effects of Drought on Rio Grande Cutthroat Trout: The Role of Stream Intermittency

Drought poses a major threat to New Mexico’s state fish, the Rio Grande cutthroat trout. This southernmost subspecies of cutthroat trout, found only in New Mexico and Colorado, has already been restricted to an estimated 12% of its former range. Now climate change, in the form of lower winter snowpack and reduced precipitation, challenges its long-term persistence. This trout tends to...

The Effects of Drought on Southwestern Pronghorns

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...

The Impacts of Drought on Fish and Wildlife in the Southwestern U.S.

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...

Understanding and Projecting Changes in Climate, Hydrology, and Ecology in the Great Basin for the Next 30 Years

This project links climate, hydrological, and ecological changes over the next 30 years in a Great Basin watershed. In recent years, climate variability on annual and decadal time scales has been recognized as greater than commonly perceived with increasing impacts on ecosystems and available water resources. Changes in vegetation distribution, composition and productivity resulting from...

Understanding Extreme Climate Events in the North Central U.S.

The climate of the North Central U.S. is driven by a combination of factors, including atmospheric circulation patterns, the region’s complex topography which extends from the High Rockies to the Great Plains, and variations in hydrology. Together, these factors determine the sustainability of the region’s ecosystems and the services that they provide communities. In order to understand...
