Tiger Mountain State Forest
The 13,745-acre Tiger Mountain State Forest, including the West Tiger Mountain Natural Resources Conservation Area, is one of DNR's most well known forests. As a working forest, Tiger Mountain State Forest is managed by DNR to provide sustainable revenue in support of public services.
Timber production, biomass byproducts, communication tower leases, and other activities by DNR in the forest help fund local services, prisons, universities, and the construction of public K-12 grade schools throughout Washington.
In addition to earning income, Tiger Mountain’s undeveloped working lands provide habitat for native plants and animals, water retention and quality benefits, and diverse recreation opportunities.
When working or visiting Tiger Mountain State Forest, always remember to:
- Be alert for other road users, ranging from heavy vehicles to bicycles, and check your speed accordingly.
- Know the fire risk and of any burn bans or Industrial Fire Percaution Level (IFPL) restrictions before entering.
