My biological part of the post still stands. How can biologists accuratly count the buck to doe ratio without knowing the fawn mortality rates. Example, if X amount of bucks need to be harvested and X amount of does need to be harvested then you can not harvest button bucks and get close to the needed numbers. If the wildlife biologists count the button bucks into the harvest and a larger amount of button bucks are harvested than more mature bucks, you had better pray for a light winter or you won't having enough carry over to replentish the supply. IMO you will be shooting yourself in the foot.
