First of all I'd like to thank everyone here for being so helpful. There is lots of good advise here.

Now that I have my small (1/2 acre)plot of imperial clover in and growing I trying to think of other improvements I can make to the land. It is not truly my land (belongs to my farther and grandmother) so I'm limited to what I can do. Any major cutting of trees is out of the question.
The property we own is about 3 acres. starting from the road and heading back into the woods the property starts with my grandmothers house and backyard then aprox 1/2 acre for wooded field (apple trees) 1/2 acre of open field (planted with imperial clover). There is next a small swamp(due to neighbors blocking up the creek to make a pond) to the far right of the property which breaks into a thick creek bottom and divides the property from left to right. On the far side of the creek bottom there is a stand of forrest most big old pines with a few oak(not sure what type of oak) mixed in among the pines. A few of the large pines have fallen into a tangled mess which is real thick and has quite a bit of new growth developing. This wodded aera is about 10 acres (only 2 acres of which we own)

I'm not really sure what else I can do to improve the habitat. I've thought about fertilizing the apple and oak trees to help with mast and apple production. This is about all I have come up with asides from possiably minerials.
Is it a waste of time and money to fertilize mast and apple trees?
Any suggestions would be greatly appreciated.
