Mule deer​ populations in Colorado have shown dramatic fluctuations since the 1960s. Beginning in the 1990s, some western Colorado mule deer herds demonstrated the most recent decline. As such, CPW focused research efforts on developing management techniques to increase the health and survival of mule deer, an economically and ecologically important game animal. 

Mule Deer Research Projects:

• Mitigating Impacts of Energy Development on Mule Deer Populations
• Effects of Habitat Treatments on Mule Deer Survival and Health During the winter
• Impact of Habitat Quality on Mule Deer Reproduction and Survival
