Trees, Shrubs, and Vines

This is a complete inventory, meaning that it include invasives. I will highlight the invasive trees, shrubs, and vines in red. Although some of these are unwanted in woodlands and savannas in the Driftless Area, they are not considered invasive. Interestingly, there are some natives that carry the invasive label.
