Wyoming’s mule deer inhabitants is seeing power losing illness (CWD) improve its prevalence all through the state, in line with analysis undertaken via 2024.
The Wyoming Recreation and Fish Division’s Wildlife Well being Laboratory launched its 2024 CWD Surveillance Report previously few weeks. The outcomes should not what hunters and different conservationists may need hoped for, though it wasn’t all dangerous information. In line with the samples studied final 12 months, mule deer noticed a rise, though it wasn’t a big one. Alternatively, whitetail deer and elk each noticed a decline in CWD proportion, and not one of the moose samples examined optimistic.
Samples examined from mule deer, white-tailed deer, elk and moose included hunter-harvest, focused and road-killed animals. Of these samples examined, 19.4% got here again optimistic in hunter-harvested mule deer bucks, 29.2% in hunter-harvested white-tailed bucks and a couple of.3% in grownup, hunter-harvested elk. The proportion of mule deer bucks elevated from 2023 at 18.9%. The odds for white-tailed deer and elk decreased from 2023 at 30.3% and a couple of.8,% respectively. There have been no optimistic CWD samples from moose.
The Fish and Recreation authorities stated they examined 5,276 samples in 2024, up from 5,100 samples in 2023. There isn’t any cost for hunters to have their recreation examined for the presence of CWD.
The CWD proportion numbers solely instructed a portion of the story. The illness was found in new areas in 2024, together with Elk Hunt Space 84, the place a useless cow elk was reportedly found by a member of the general public late within the 12 months, who turned the carcass over to Fish and Recreation, which discovered it optimistic for CWD. Elk Hunt Areas 62 and 87 additionally had been discovered to include CWD earlier within the 12 months, in addition to 4 elk feedgrounds within the state’s western part.
Deer Hunt Areas 31, 53, and 94 had been additionally newly confirmed to have CWD-positive animals.
At this level, the Lander Area’s Venture Herd has the very best CWD proportion amongst whitetail populations, measured to be 66.3 p.c, with the Shoshone River herd within the Cody Area in second place at 47.6 p.c. In southeast Wyoming, the Iron Mountain herd has the very best proportion of CWD-positive elk, estimated at 10.1 p.c, and the North Bighorn herd in north-central Wyoming has jumped to 9.1 p.c from its 7 p.c prevalence over 2019-2024.
Take notice that even these numbers don’t essentially apply to the herd throughout the entire area. The wildlife authorities clarify their system this fashion:
To find out CWD prevalence in particular person herds, five-year averages had been calculated to make sure a big pattern measurement … Prevalence calculated on the herd till degree offers managers with perspective on herd unit well being and might direct herd degree administration actions. Nonetheless, CWD ranges should not uniform throughout a herd and might accumulate in sizzling spots of upper focus inside these herd items.
However it’s nonetheless a grim factor. Final 12 months, Wyoming’s wildlife consultants believed 95 p.c of the state’s mule deer looking areas and 62 p.c of the elk looking areas had been endemic for CWD. It’s spreading to all deer populations in every single place, slowly—aside from moose, it appears.


How one can assist combat CWD
To assist authorities attempt to handle the issue, the Recreation and Fish division says CWD sampling is vital for early detection, to allow them to determine methods to take care of the difficulty earlier than it turns into harmful to the herd. That’s the place outdoor lovers can play an vital half.
“Wyoming’s CWD surveillance wouldn’t be potential with out the participation of our hunters,” stated Jessica Jennings, supervisor of the Recreation and Fish Wildlife Well being Lab. “We encourage hunters to test the Recreation and Fish web site for the 2025 precedence and obligatory testing areas, test present CWD prevalence on the interactive CWD map, and irrespective of the place you hunt, please think about having your animal examined for CWD.”
