My farm sounds just like yours. It basically consists of locust, hedge/osage orange, cedars, elm, hackberry, walnut, and little bit of shingle oak, box elder, and cherry mixed in. The brush on ground level is thick with buck brush/coral berry, multi flora rose and honey suckle.
Ive been working on removing the multi flora and honey suckle. I sort of like the honey suckle as long as its not to thick, they are sort of neat when they get huge. Hate multi flora. My farm really likes to stick and snag you with all the locust and multia flora. There are areas that are impenetrable with multi flora. I hoping killing the muliflora will help get more coral berry/buck brush and other natives/good things to grow up. At the very least it will create more space for wildlife to be able to move around and call home.
I'm also hoping to start dropping some trees/hinge cutting to create some more browse and cover. Hopefully do a little bit of edge feathering along the field edges. Going to also try and start killing young locusts that are manageable.
It seems to hold deer and turkey pretty well as is before I've done anything.
Heres a spot where its a little more open, but the cover is thick at ground level:
You can see coral berry/buck brush at ground level and hedge balls on the ground.
