Clover is probably your best option in a situation like that. BUT...let me throw a few words of caution your way in regards to "in timber" plots.
You need to open up enough canopy to get sun to the floor for I would say, 4-8 hours per day. That will require more tree removal than what many anticipate...you really need some good openings that catch the summer sun.
You will probably need to amend the soil, adding fertilizer and lime. Do a soil test and go from there. Don't skip this step if you want success.
You can contour your plot around current tree stand locations and create natural pinch points too...but I would recommend not leaving tree standing in the plot...as you will always be removing fallen branches AND they take up a lot of moisture and minerals from your plot. Although I have been known to leave a good tree or two standing in the plot...particularly if they have good low hanging branches that the bucks will scrape under.
