Some of the trees I've been looking into have been sawtooth oak trees, apple trees, persimmon, crabapple, etc. Probably some honeysuckle bushes, too.
Wisconsin is too far north for sawtooth oak or persimmon to survive.
Apple and or crabapple trees work well, but need to be fenced for protection. It takes about 18' of fence for a 5' diameter circle.
Stick with native bushes and trees. People seldom want to plant oaks anymore because they want short term gains. [*]Oaks:[*]White Oak (Quercus alba),[*]Bur Oak (Q. macrocarpa)[*]Northern Red Oak (Q. rubra)
Dogwoods (Cornus spp.):
Pagoda Dogwood (C. alternifolia)
Red-Osier Dogwood (C. stolonifera)
Silky Dogwood (C. amomum)
Viburnums (Viburnum spp.):
Nannyberry (V. lentago)
Downy Arrowwood (V. Rafinesquianum)
Wild Plum
High bush cranberry

Stay away from non-native invasive species such as [*]Tartarian Honeysuckle (Lonicera tatarica)
