Garlic mustard pull at Cottage Grove Ravine Park

Thursday, May 19, 2022 - 6:00pm to 8:00pm
Cottage Grove Ravine Regional Park
Volunteers with their garlic mustard haul at Ravine Park

With 515 acres of hills and heavily wooded ravines, a small lake and a smattering of small prairies, Cottage Grove Ravine Regional Park features a beautifully diverse landscape. A glacial tunnel valley bisects the park, featuring 80- to 100-foot slopes which are home to a compelling array of vegetation and habitats. The ravine ends in a small lake where people enjoy fishing, birdwatching and picnics.

In addition to being beautiful, the park's dramatic natural features play an important role in water quality, helping to filter pollution from post-rainstorm runoff that would otherwise enter the Mississippi River. The restoration work at Ravine Park is part of a larger effort in Washington County — involving FMR, Washington County, South Washington Watershed District, 3M Foundation and other partners — to protect and preserve a natural green corridor for our waters, our wildlife and our heritage.

FMR volunteers have been contributing to the restoration of Ravine Park for about ten years. Join us as we build upon our successful efforts and help the oak forest.

Volunteers are needed to remove garlic mustard, helping to make way for native woodland and savanna plants that historically were found here. The native plants provide habitat for birds, bees and other insects and wildlife, and better filter water pollution.

All are welcome! No experience is required and all training and supplies will be provided. Entry to the park, normally $5, is free for participating volunteers!


A short walk on an unpaved trail is required to get to the worksite. The worksite includes moderately steep hills and volunteers will be working on uneven terrain.
