New Missouri Deer Regs?

[Ben.MN/WI]

Here are some of the CWD areas with significant declines. It appears that a common thread as been late identification of the disease and little management once detected:

• Southwestern Wisconsin: A major 2025 study by the Wisconsin DNR indicates that CWD is dramatically decreasing white-tailed deer survival in the region, with prevalence is as high as 44% in does and 55% in bucks. Population declines are now very noticeable.
• Southeastern Wyoming: Mule deer populations are now showing an annual population decline of 21% where prevalence exceeds 20%.
• Wind River Reservation: This mule deer herd is considered to be at risk of local extinction, with an estimated 66.3% prevalence rate in 2024–2025. Harvest levels in this area have dropped by 90% since 2020
• Colorado: The White River herd has reached 25% buck prevalence in 2025. The Bear's Ear herd has reached 20.8%. Both areas have seen over 50% reduction in populations.
• Arkansas:
  Four year average annual declines in the following testing areas (2021,22,23,24): Erbie: 13%; Gene Rush: 13%; Tyler Bend: 15%
• Tennessee: Fayette & Hardeman counties have seen population declines of 40%.
  

I haven't heard of a population decline in SW Wisconsin, where did you find that information? I did read their reports the referenced a much lower survival rate for CWD positive deer in their trap and collar study though, but I haven't found data on a population decrease because of that.

I think it is very likely that the population will drop there eventually, but I haven't heard of that yet.

Yeah from real world info I haven’t heard anything negative in the supposed ground zero of cwd there

Yes, I know a lot of people who hunt SW Wisconsin and I'm not aware of any population reductions there. That's not to say it hasn't happened in some areas, but if it was widespread, it seems likely that I would have heard about it living just across the border in Minnesota.
