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...

This data set characterizes the thermal regime in a number of Colorado and New Mexico streams that contain populations of Rio Grande Cutthroat Trout (Oncorhynchus clarkii virginalis) or have been considered potential restoration areas for the fish. The majority of these streams had no previous record of continual temperature records. When compared to Colorado water temperature criteria (Cold Tier 1), a portion of these populations appeared to be at risk from elevated stream temperatures, as indicated by exceedance of both acute and chronic water quality metrics. Summer water temperature profiles recorded at sites within current Rio Grande Cutthroat Trout habitat indicated that although the majority of currently...

Cutthroat Trout,
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 occupy small and fragmented streams, which are at higher risk of drying up during drought events. Yet, the full extent of drought impacts to Rio Grande cutthroat trout is unknown. To address this knowledge gap, researchers examined the effects of drought - in particular stream intermittency - on the growth and survival of Rio Grande...
