To determine this look around at the vegetation from shoulder height to ground level. Is it mowed down? Is there plenty of buds and shoots? Look at individual bushes and shrubs and see if they are being browsed heavily. If you think you have too many deer send us a few in VA LOL!

You could either plant browse species for them, or use a timber management strategy to open up the timber to new growth. Or, you could use your gun to manage the numbers of does. It's all up to you!
