Lower the bag limits. Cut out doe harvesting. But shortening the season will affect how people are able to hunt the rut. Within 25 miles of my house the deer rut from late October to late January. How could you possibly zone that ? I remember in the 80's and 90's you could not shoot a doe in my county. Now it's open and hardly anyone takes any. Buck limits and antler restriction could be changed and would probably help more than anything.
