Buckthorn is highly invasive in native habitats throughout Minnesota, including those in Eden Prairie.
It aggressively invades wetlands, woodlands, meadows and other areas. According to the Minnesota Department of Natural Resources, buckthorn:
- Outcompetes native plants for nutrients, light and moisture
- Degrades wildlife habitat
- Threatens the future of forests, wetlands, prairies and other natural habitats
- Contributes to erosion by shading other plants that grow on the forest floor
- Serves as host to other pests, such as crown rust fungus and soybean aphid
- Forms an impenetrable layer of vegetation
- Lacks "natural controls" like insects or disease that would curb its growth
Buckthorn can be difficult to identify. Before beginning a project, contact the Forestry and Natural Resources Division for assistance.
