Population trends and predicted trajectories of American Pronghorn (Antilocapra americana) in the American Southwest


May 2013 - May 2016


Our objectives are to: 1) determine how widespread the decline in American pronghorn is in the Southwest; 2) identify causal, climatic factors which best explain these declines; 3) forecast the trend and geographical extent of these causal, climatic factors over the next century based on current climate change models for the region, including downscaled climate models developed at the SW CSC; and 4) relate these climatic forecasts to pronghorn population trends over future decades.
