Using 2021 data, which I believe to be reflective of most years as a %, approx. 91,000 youth/adult turkey hunters entered the woods and killed approx. 52,000 turkeys. According to the sample study "57% of adult hunters and 46% of youth hunters harvested at least one turkey during the 2021 spring turkey season. Among all successful adult hunters, 61% reported harvesting only one bird, 25% reported exactly two birds, and the remaining 15% reported three birds."
The number of hunters harvesting 2 or more that hunted public land exclusively was less. Those that hunted public/private fell in that average range posted above with exclusively private hunters being above the average.
The reduction in bag limit is only going to save about 15% of total kills from a purely basic view point, I don't know how many hunters killed jakes but in 2021 approx. 5,000 were killed. The reduction may or may not save them, I suspect it will because people are actually going to have to hunt turkeys now instead of pop shooting them, although the number saved might be irrelevant in the grand scheme, idk(maybe more site specific).
I think the reduction in the limit will have more of a psychological impact on hunters vs biological impact on turkeys. I think the delayed opener will of course be beneficial and add to that the tighten of the screws on public lands and it might keep some of the blood thirsty wanna be influencers away from our great state.
