Studying the Shy Sonoran Pronghorn
The endangered Sonoran pronghorn once ranged widely in Arizona, California, and Sonora, Mexico. Now, according to the U.S. Fish and Wildlife Service (USFWS), only about 160 free-ranging animals live in the U.S., with an additional 434 living in Mexico.
David Christianson, an assistant professor in the School of Natural Resources and the Environment, wants to know why their numbers are low. With funding from the USFWS, Christianson is studying the impacts of humans on the spry tan and white ungulates.
