Maple Grove City Council Approves Forest Preservation Buckthorn Treatment Proposal

Nov 10, 2019 06:49PM ● By Wendy Erlien

At the Oct. 21 meeting, the Maple Grove City Council approved authorizing fund of $14,300 for buckthorn treatment in the South Forest Preservation Area. 

The approval came upon the recommendation of the Arbor Committee at their Oct. 10 meeting. 

"Buckthorn threatens the future of forests, competes with native plants for nutrients, and degrades wildlife habitat," according to a memo provided to the city council.

The buckthorn treatment in the forest preservation area (pictured below) is aimed at preventing buckthorn coming back "where it has already been eradicated," the memo continued

Existing buckthron was removed in 2017 and 2018, however, follow-up treatment was recommended since "buckthorn seeds can remain in the soil where buckthorn was present up to five years."

The Forest Preservation Area is scheduled for annual evaluation to determine if additional follow-up treatment is needed. 

"Controlling these seeds after the initial removal is important to minimizing the return of buckthorn," according to a memo provided to the city council.
