I agree. If the season was shortened, public land overcrowding would increase, the average NR hunter would lower expectations, increase the number of days they plan to hunt or both. They may only get to draw every other year, spend a lot of money to travel, on licenses, etc. and often have that need to go home with meat - any meat.
Requiring every kill to be reported would be a valuable addition to other data and would show what dates deer are taken, where, etc. I have hunted deer 6 years in MT and not once have I ever been required to report my kill and never got a phone call asking about my hunt.
NY has had mandatory reporting for many years. It's easy to do over the phone, smart phone or online. It is automated/computerized so it's inexpensive to do. The estimated report rate for 2020 was about 45% on over 250,000 deer killed. Combined with other data they figure they get within 2% accuracy of the actual totals. Doesn't fix the problem, but helps support "science based decisions".
