Question: Can I harvest mushrooms in Minnesota state parks and state forests?
Answer: It’s OK to harvest edible fruit and mushrooms in state parks as long as they are only for personal, noncommercial use. However, you are not allowed to pick wildflowers or other plants (edible or not), even for personal use.
In state forests, you may also harvest mushrooms and fruit for personal use. If picking for commercial sales, you need to first get a permit from your local forestry office.
