Invasive non-native plants

The following plants, should not be planted in or near streams or wetlands as they have the potential to completely dominate all native plants.

If possible, existing stands of invasive plants in stream corridors and wetlands should be removed and replaced with native plants that can be found in our Native Plant Finder.
