Forest Products Available under Incidental Use

Harvesting minor amounts of berries, greenery & cuttings, mushrooms, and transplants for direct personal use is considered "incidental use" on the Forest and doesn't require a permit nor payment. 
NOTE: The harvest and transport of firewood from the national forest does require a permit. However, small amounts of downed and dead wood can be collected for on-forest camping use only. Learn more about harvesting firewood.

The Mt. Hood National Forest waived the requirement to obtain a free use permit to forage limited quantities of berries, cuttings, mushrooms, and transplants, and determined that harvesting minimal amounts of these products constitutes "Incidental Use," per Forest Service Handbook. Read the letter signed by the Forest Supervisor here.

Below are the products and amounts that may be harvested under incidental use guidelines. Following these rules, a permit is not required and there is no cost to collect these products. Products gathered under incidental use must be for your own personal use and cannot be sold or exchanged in any form, nor be used to make something to sell. Harvesting a product with intent to sell or exchange requires the purchase of a commercial permit from our district offices, if allowed for that product. Contact us for more information.

Products and quantity limits may change from time to time to protect Forest resources. It is the responsibility of the harvester to stay current with updates. You may contact any of our offices or check this page for the latest information.
