Hi Neal:
It's extremely difficult for someone to offer tree species selection advice without knowing knowing specific site details: soil texture, drainage, pH, fertility, water table, slope, etc.
Therefore, it would behoove you to work with your local USDA-NRCS office and/or IDNR district forester to evaluate your property (soils/site) prior to making random species selection.

Best of luck!
