Grey Cloud Dunes Scientific and Natural Area, Cottage Grove
Volunteers at Grey Cloud Dunes in 2020

Our work takes place on Dakota homelands. Learn more.


Located in Cottage Grove, this spectacular Scientific and Natural Area (SNA) features two sandy terraces along the Mississippi River and dramatic views. Home to a rare dry prairie, this area provides essential native bee, butterfly and wildlife habitat and is home to a variety of rare plant and animal species. After a brief orientation and a short hike, volunteers will work with FMR ecologists to help remove sumac, a shrub native to Minnesota but aggressive in this ecosystem. Without removal, sumac can overtake this rare and vital habitat, shading out the shorter native prairie plants. Other tending and restoration tasks may also be needed.

All tools and training will be provided at the event, and no experience is necessary. All volunteers are encouraged to work at their own pace. However, due to tool usage, including loppers and saws, this event is not suitable for youth. The designation of this type of natural area is meant to protect rare, fragile plant and animal habitat. Please note that Grey Cloud SNA does not allow pets, nor does it feature amenities – trails or restrooms.


A hike of up to 1/4 mile is required to get to the worksite. Volunteers may then work on slopes with uneven and difficult-to-navigate terrain.
