2026.06.27 Big Stone National Wildlife Refuge Volunteer Event | Ortonville

Thanks for joining us at Big Stone National Wildlife Refuge! Great River Greening is embarking upon a long-term partnership with the refuge to support their conservation efforts and this event marks our first partnership event together.

Containing over 11,500 acres, Big Stone National Wildlife Refuge is located at the headwaters of the Minnesota River and provides vital habitat for a variety of species, especially ground-nesting waterfowl.

Volunteers will remove invasive species and haul recently downed wood to open up and support vital outcrop habitat, home to the rare ball cactus, one of three native cacti to the state of MN. Volunteers will also spread native seed once areas have been opened.

Please note registrants will receive updates on any changes and final event details as the date approaches.

This event is open to all, and any necessary training will be provided.

Day of: Please arrive promptly, allowing time for parking and short walk. Our worksite areas will be adjacent to the Granite Outcrop trail head parking lot. Terrain will be a mix of flat hiking trails and occasional off-trail terrain with a slight rise in elevation.

Safety: Ensuring safety is our highest priority. It is important that event participants wear close-toed shoes and long sleeves to protect against the elements. We recommend dressing for the weather; layers are key.
