Nestled in a remote valley that drains to California’s famous Lost Coast, the Mattole River watershed spans from its headwaters near Whitethorn down to the sea where it terminates at Petrolia. The Mattole watershed is a peculiar Humboldt County coastal watershed in that its forests are largely composed of a mix of fir and hardwoods, rather than being dominated by the giant and majestic redwoods found elsewhere in the region.

Pre-European settlement, the forests of the Mattole appear to have been left unmanaged, while grass lands were burned to maintain oak acorn harvests, and to manage conifer encroachment.

Post-European forest management activities and old-growth logging in the Mattole began in earnest after World War II. By 1988, approximately ninety percent of the original old-growth forest had been logged.

In the North Branch of the North Fork of the Mattole, much of the remaining old growth (approximately 48 percent), is still in privately-held industrial timberland ownership. The majority of this property is held by Humboldt Redwood Company, the successor to the Pacific Lumber Company.
