I don't know the variance on number of deer taken each season but 26% lower than average seems like a lot. What have the thoughts been on why there were 26% fewer taken that season?
So, KDFWR has had a CWD contingency plan for over 20 years. This plan would be triggered when a deer was found to be CWD positive within 20 miles of the KY state border and went into effect when an adult doe near Cottage Grove, in Henry County, tested positive. The 5 counties nearest Henry Co were Fulton, Hickman, Graves, Calloway, & Marshall Counties in KY. These became the first CWD Surveillance Zone counties. (Ironically, I was born in Fulton Co, grew up in Hickman Co, hunt in Graves Co, live in Calloway Co, and, at the time, worked in Marshall Co, so lots of friends & acquaintances were depending on me.)
New restrictions in the CWD Zone including a ban on baiting & minerals & mandatory in person testing of any deer harvested during MZ & modern firearm season (in addition to still having to TeleCheck each harvested deer). The compliance with the in person check stations was about 94%. We had like 17 check stations in the 5 counties, many of which were at processors where many ppl were going to take their deer any way. Many older hunters had been telling me for years that they wished they could go back to the in person check stations like when they were kids. This gave them a chance to do that plus KDFWR sweetened the pot by giving away a back pack sized thermos, orange vest, or camo hat to each hunter. This was well received. BTW, I was curious about the 6% that didn't comply (who TeleCheck'd a deer but didn't check it in person. These were mostly Amish hunters. Obviously, a 15 mile distance to a check station for them is a 30 mile ride with a deer in a buggy, so we started sending wildlife techs to them. The rest were old guys who simply didn't know they needed to check their deer in person. There was very little negative feedback for mandatory in person checking.
There was a significant amount of complaints about not being able to bait. Many primarily younger hunters had never deer hunted except over corn & were convinced they couldn't hunt successfully except over bait.
Finally, a significant percentage of hunters simply understood little about CWD, didn't try to learn about it, & believed whatever others told them rather than taking the time to learn about CWD themselves. The truth here is it is a complex, incompletely understood disease, easy to confuse with blue tongue, and most deer hunters weren't used to learning about wildlife diseases.
So, the big reasons why I believe there was a significant drop in deer harvested in the first year of the CWD Surveillance Zone is confusion over the disease itself, not liking the ban on baiting, and being unable/unwilling to take harvested deer to an in person check station.
