I agree that something needs to be done, but simply closing the areas to human activity won't solve the problem unless it is STRICTLY enforced and monitored daily. I know of some areas in Montana & Wyoming that are "supposed" to be closed to human activity until May 1st...and it's posted. The law-abiding guys, and the guys who care about the well-being of our wintering elk & deer herds stay out. However, when we go up on opening day it's rare to find a fresh shed because all the renegade guys sneak in and pick 'em all up before the opener.
So, unless our BLM, Forest Service, and Game & Fish departments decide to make it a priority to monitor this and hit the bad guys where it hurts then nothing will change except the bad apples will have a hay day! In fact, there's a lot of guys around here who would love it if they closed areas because they would clean up without as much competition!
I think that if these agencies/departments would make it as serious as poaching trophy animals then something good "could" come out of it. If a guy is caught in a closed area shed hunting then they should confiscate his vehicle/4-wheeler/motorcycle/snowmobile, take away their hunting priveledges in a multiple state area, search their homes and take any and all antlers, etc. A little $100-$500 fine won't do anything because those guys will make way more than that when they sell their antlers. They should also empower other antler hunters to do more if they see unlawful things happening out on the wintering ranges. At least use those people as resources and actually follow up on their leads!
So, I believe that unless these regulations are strictly enforced and monitored, the only people who will lose out are the law-abiding shed hunters.
