The following non-native plant lists were provided through the Wisconsin Department of Natural Resources Bureau of Endangered Resources. These plants have the potential to invade wild areas and out compete native species. We urge people to remove any plants listed below from their shoreline areas and avoid planting these species and their cultivars.
The tables below are divided into three categories; vegetation type, habitat where the plants are found, and a measure of the plant's invasiveness potential. The following abbreviations are used:
