Natural resources

Forestry

Forestry is practiced on conifer tree farms in the unpopulated hills, which receive over annual precipitation, and possess a cool, cloudy climate. Native tree species include Pacific silver fir, Douglas fir, and western hemlock.

Wind power

In 2009, a 120 megawatt wind farm called was proposed in the Doty Hills. It was to be built on tree farm land leased from Weyerhaeuser, and would be the first large wind farm in the Pacific Northwest coastal hills. In November 2013, the developer put the project on hold due to insufficient demand for renewable energy.
