The Wyoming Game and Fish Department alerted the public that chronic wasting disease (CWD) has been confirmed for the first time in Deer Hunt Area 156, located in the Jackson Region. The discovery was made after testing an adult mule deer buck that tested positive for the disease.
Location and Nearby Positive Areas
Deer Hunt Area 156 is bordered by several zones that have previously reported CWD cases: Hunt Area 128 (positive in 2016), Hunt Area 148 (positive in 2021), Hunt Area 155 (positive in 2022), and the adjacent Grand Teton National Park, which recorded a positive case in 2018. The new confirmation underscores the expanding footprint of the disease in western Wyoming.
What CWD Means for Hunters
CWD is a prion disease that is 100% fatal to infected deer, elk and moose. Because the disease cannot be treated, early detection and monitoring are critical to managing its spread. The Game and Fish Department urges hunters to be vigilant, especially when hunting in priority or mandatory testing areas. All hunters are encouraged to submit harvested deer for free CWD testing. Samples can be dropped off at any Game and Fish office or mailed according to the instructions on the department’s website.
How the Public Can Help
Beyond submitting samples, the department asks the public to report any deer, elk or moose that appears sick or injured. The nearest office for the Sheridan region can be reached at (307) 672‑7418. Detailed maps of CWD‑endemic zones and additional information are available on the Wyoming Game and Fish Department’s CWD webpage.
Why Monitoring Matters
Continued monitoring allows wildlife officials to assess the potential impacts of CWD on Wyoming’s iconic big‑game populations and to evaluate future management actions. By tracking the disease’s prevalence, the department can make informed decisions about hunting regulations, habitat management, and disease mitigation strategies.
What Hunters Should Expect
Hunters in the newly affected area should expect mandatory testing of harvested deer and may see adjustments to hunting quotas or season dates as the department gathers more data. The agency remains committed to transparent communication and will provide updates as the situation evolves.
