Regenerating Oklahoma Cross Timber/Prairie Woodland

My family has property about 20 minutes outside of the witchita mountains of Oklahoma,  zone 6b-7a.  I am curious about native trees bushes, etc... that I can incorporate in my existing couple acres of woodland and also my future planting of trees in an open section of the woodland, a lot of the trees are standing dead I not here place and the forest needs young life! I need suggestions please!  I am interested in any tree that serves a purpose in helping the forest whether it it be for critters or for humans as well, nitrogen fixing etc.

Howdy Benjamin,

Great to hear about your project! I'm at the opposite end of the Cross Timbers, down in Texas just North of the DFW metroplex. I'll send something purple your way, a document I've been working on listing the woody and not woody plants I've either worked with or plan to work with down here, hopefully some of that will be useful for you!

The trees that I remember that are native to Oklahoma are chinkapin oak, bur oak, and dogwood.

All these would be loved by wildlife for the acorns and dogwood is just such a pretty tree.
