Gateway Arch National Park

Restricted

US National Parks (National Park Service)

Removing plants is prohibited in national parks unless the superintendent allows it. Gathering is limited to items the park designates. Mushrooms are not named in the rule and parks differ, so check the park first.

36 CFR 2.1(a) prohibits possessing, removing or disturbing plants or their parts. Under 2.1(c) a superintendent may designate certain fruits, berries, nuts or unoccupied seashells for hand gathering for personal use or consumption, but only after a written determination that gathering will not adversely affect park resources. The superintendent may also limit the size, quantity or location. Sale or commercial use of natural products is prohibited. The regulation does not name mushrooms, so it varies by park. Glacier's compendium prohibits picking mushrooms, while Mount Rainier allows one gallon per person per day for personal use. Check the park's compendium.
