I’m not sure where you’re getting your numbers at. Kansas first had it in the wild in 2005, only 4 years longer than us. They have never regulated baiting and already have 40% + prevalence in NW Kansas. Additionally, Kansas recent surveys reported less deer (both sexes) and declining deer numbers in NW Kansas where their CWD hot spots are. Kansas Game and fish staff can confirm they get reports of sick CWD deer in that area and have been for the last couple years.
Deer pops are doing well in eastern Kansas where prevalence is low. But if prevalence gets high there, they will likely see population impacts as well….just like every place with high prevalence. No exceptions to this. Some just more severe than others.
Wyoming and Co have had the disease for 40 years in the wild, they are still significantly better off in most areas of the state compared to places like Sask where baiting is widely popular. Both in prevalence and geographic spread.
Again, not sure where you get your numbers. Colorados deer herd has been almost cut in half since the early 2000s. Sure that’s not all due to CWD, but it ain’t EHD. And only so much of it can be attributed to increased harvest. Some is due to winter, sure. But we also know winter is harder on CWD+ positive animals. If you talk to the folks who live and work in the hotspots, all the ones I’ve talked to confirm CWD is an issue and has caused noticeable impacts to deer populations and age structures. Some areas worse than others. 40 years with the disease and they’re still doing better than Saskatchewan and in some measure better than Kansas right next door.
Why is that? I subscribe to occams razor…encouraging baiting and incentivizing feeding by allowing hunting over bait creates the perfect environment to spread a contagious disease. That is just common sense. Someone denying that is not living in reality. Especially with a disease that is not easily transmitted like the cold or flu. It takes large doses or repeated exposure. The states that have banned baiting fair better with the disease, almost overwhelmingly.
Also, not correct about New York. New York’s first case in the wild was in the early 2000s. They went in and culled a bunch of deer immediately in that area and have been CWD free in the wild ever since. There was recently a positive in a deer farm facility….iirc it was a deer that was shipped in from somewhere. Maybe someone can correct me on that.
