I first though hackberry whenI saw the bark - more mature trees tend to have the roughness of the bark spread out more. Best way to tell for sure is to get a branch in your hand and take a photo. I realize that may not be possible. Based on what you have provided I would agree with hackberry. If it is hackberry it isn't all that special. They will produce a berry (similar to a mulberry) that the birds like, but is of little use to deer, timber quality is low as well. My place is covered in it. I am removing it where needed - likes similar habitat where you would find black walnut (at least in my area). Not a terrible tree, but not one I would plant intentionaly to improve habitat. If I have anything of decent value being crowded by a hackberry - the hackberry meets the chainsaw.
