Invasive Species are No Longer Safe with Great River Greening

Posted by on May 15, 2012

Throughout the country, existing plant communities are being seriously threatened by invasive plant species. Active management to control invasive plant species is essential to restoring the health of plant communities.

Accounting student Jacob McClure, Criminal Justice Student, John Donaldson and Service Learning Coordinator, Joel Bisser joined with Great River Greening and over 100 other volunteers on Saturday, May 12 to remove invasive buckthorn along the Mississippi River at Cherokee Bluffs Regional Park in St. Paul.


Buckthorn was originally brought to the US from Europe as a popular hedge and wind break, but it quickly became invasive because it out-competes native plant species for light, water and nutrients. Since it chokes out native trees and plants, it also degrades natural wild life habitat.

“I never knew there was so much buckthorn,” said Jacob, “and now I know why it is a problem.”

Buckthorn is a serious issue across the south metro in Minnesota and can be found in many backyards and city and state parks. For more information about buckthorn and how you can restore your backyard and parks, please visit the Minnesota Department of Natural Resources website:
