How do you identify buckthorn?
Buckthorn is a shrub or small tree that can reach a height of 15-20 feet with a trunk diameter up to ten inches. Buckthorn leaves are generally round, pointed at the tip and have toothed edges. Long after native trees and shrubs have lost their leaves in the fall buckthorn leaves are still green. Buckthorn can be easily confused with native cherry trees, which have similar looking bark and purplish berries for fruit. Once you become acquainted with buckthorn you will be surprised how prevalent it is in the metro area.
Why is buckthorn an issue for park users?
Park visitors feel more comfortable walking through park and woodland areas where they can actually see for some distance. Dense thickets of buckthorn can reduce visibility along pathways and at intersections, decreasing park users’ sense of safety.
How is buckthorn controlled?
Buckthorn is a very persistent plant. Park Board removal efforts consist of cutting down the shrubs and treating stumps with herbicides. Each mature buckthorn tree produces many seeds. The seedlings that result are the “second wave” of buckthorn control in forested areas. Buckthorn removal is an intensive task that is ongoing for many years.
What you can do to help
Buckthorn is now a restricted noxious weed in Minnesota. It can no longer be sold or planted by nurseries in Minnesota.
While there are no Minneapolis City Ordinances that require people to remove buckthorn from their property, we encourage residents to remove buckthorn and other invasive woody shrubs from their property to reduce the spread to park areas.
