Endemic chronic wasting disease causes mule deer population decline in Wyoming

''Our findings support CWD as a population-limiting disease of mule deer with the potential to cause dramatic declines that resemble local population extinction.''

''Other studies have found a negative association between CWD prevalence and λ [11,12,40,42], but none have documented λ estimates resulting from endemic CWD as low as those reported here.''

Endemic chronic wasting disease causes mule deer population decline in Wyoming

While we were antelope hunting in one morning this last weekend we saw over 1,200+ mule deer and I'm not exaggerating. The high density of animals makes them way more susceptible. However, they've had plenty of die-offs with CWD before, they've come back from it strongly.

Btw, the sample area was over hunted and mountain lion numbers are high. "Mountain lion predation was the number one cause of mortality."

"The hunting of does and fawns was largely eliminated in 2009 in response to poor population performance." Not because of CWD, because too many doe tags were alotted and if I remember right people talked about a hard 2007-2008 winter.

I know this is Colorado, but just saying the winter was bad.

"The last full-blown winter feeding operation conducted in the Gunnison Basin happened during the winter of 2007-2008 when a sustained period of extreme cold, combined with more than 100 inches in snow, resulted in the loss of more than 30 percent of the fawns and female mule deer. That feeding operation cost the state approximately $2.8 million."


"GREEN RIVER, Wyo. (AP) – A mortality survey of Wyoming’s largest mule deer herd indicates that the harsh winter took a toll on the animals.

The annual mortality surveys for the Wyoming Range mule deer herd were conducted this spring near Cokeville, Pinedale and Big Piney and near Leroy in the Bridger Valley.

Wyoming Game and Fish Department biologists and others counted 313 dead mule deer during the Cokeville, Pinedale and Big Piney surveys.

Officials said an additional 340 dead mule deer were found on the Leroy survey in Uinta County, for a total of 653 dead deer.

Game officials noted an unusually high number of adult deer deaths."
