The United States Congress designated the Elkhorn Ridge Wilderness (map
) in 2011 and it now has a total of 11,001 acres
All of this wilderness is located in California
and is managed by the Bureau of Land Management.
The Elkhorn Ridge Wilderness contains rugged Coast Range ridges covered with thick forests of redwood, Douglas-fir, and tan-oak. There are two major forest types encompassing the area: mixed evergreen forest and redwood forest. Late-successional and old-growth stands of Douglas-fir are scattered throughout the area. Chaparral communities are found on south-facing slopes and ridgetops. A seven-mile-long segment of the South Fork Eel River, designated as a Wild and Scenic River, flows through and bisects the wilderness.
Notable wildlife species include the federally-threatened northern spotted owl, the federally-endangered bald eagle and peregrine falcon. Anadromous fish species such as Chinook salmon, coho salmon, and steelhead utilize the South Fork Eel River and its tributaries as rearing and spawning grounds.
