Is the canopy open enough to plant some food plots? I'm not talking about fields; but places where a plot the size of a ball diamond. If there isn't much food, even little plots will help. How about the skidder trails? Strips of Rye, Oats, Clover may help bring in the deer and also provide browse on the site. Got any Honeysuckle? Fertilize it, a great browse. Maybe plant some Sawtooth Oaks, quick growth and not too long to wait for acorns compared to White or Red Oaks.
Salt and mineral licks are mostly good in the spring as usage tapers off as forage gets dryer.
Remember, you don't have to think big on plots sometimes little ones can work real good. I have over 6 plots, the biggest about 1/2 acre. Think small to start out.
