I now have what I'm calling "Wildlife Openings" that support small game as well. I basically took small fields, maybe a 1/4 to 1/3 acre and established them in clover. I then planted and caged soft mast trees in them. I that point I stopped doing everything. I don't maintain the trees or the clover. I just let it go wild. After about 4 years or so, the woody growth is beginning to get large enough to challenge my bushhog. That is when I mow them back. I'm just using the bushhog to keep them in early succession. These tall weedy areas are good rabbit habitat.
Thanks,
Jack
