The University of Wyoming and the Wyoming State Veterinary Lab (WSVL), in conjunction with the Wyoming Game and Fish Department (WGFD) are involved in a multi-year project to quantify the effects of Chronic Wasting Disease (CWD) on South Converse mule deer herd. While CWD is lethal to mule deer and other ungulates, what is not understood is the wider effects on the general population when CWD concentration increases in a localized area.
The Casper Journal  has a detailed write up on the study and why it's being conducted.
"The South Converse mule deer herd, which is Hunt Area 65 south of Douglas and Glenrock, has the highest known prevalence of CWD in a deer herd anywhere in the world," said Casper WGFD biologist Justin Binfet. "CWD prevalence in the herd has increased almost every year for the last 10 years and it was found to be in 48 percent of all hunter-harvested deer in 2010. Over the same time frame, this deer population has been reduced by 50 percent. This study is looking at 'why'.
