I prioritize my trees as follows (My property is in west central Illinois and timber value really isn't a consideration for me.) High value to Low value: White Oak, Swamp White Oak, Bur Oak, Persimmon, Pin Oak, Mulberry, Red Oak, Black Oak, Cherry, Shingle Oak, Hedge, Sycamore, Elm, Hickory, Ash, Silver Maple, Honey Locust. Some of this list is skewed by considerations specific to my property and how much I despise silver maple. Walnut would be near the top of my list if I actually had any that were decent. Mature trees are somewhat "overrated" for their contribution to deer habitat, so open up that canopy allow allow regrowth, shrubs, and herbaceous growth to provide food and cover within reach. If managing for turkeys, make sure they have flight paths to roosting trees and some open areas for brooding. If you don't have invasives consider yourself lucky and stay on guard, as they will find your place eventually.
