The 13,745-acre Tiger Mountain State Forest, near the West Tiger Mountain Natural Resources Conservation Area, is one of DNR's most well-known forests. In 2009, 11,200 acres purchased to its south, including Rattlesnake Mountain, became Raging River State Forest.
 
As working state forests, Tiger Mountain and Raging River are 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 schools throughout Washington.
 
In addition to earning income, these undeveloped working lands provide habitat for native plants and animals, water retention and quality benefits, and diverse recreation opportunities.
