The United States Congress designated the Yuki Wilderness (map
) in 2006 and it now has a total of 53,717 acres
All of this wilderness is located in California
and is managed by the Bureau of Land Management and the Forest Service.
The ancient forests of the Yuki Wilderness consist of ponderosa pine, Douglas fir, Shasta red fir, white fir, and incense cedar. The region also hosts seven species of oak, an unusually high number for any one place to have. Wildflower displays are truly spectacular.
Several rare animals also live in the Yuki Wilderness, including marten, goshawk, northern spotted owl, and prairie falcon. Elk and Thatcher creeks, and the Wild and Scenic Middle Fork Eel River host populations of chinook salmon and steelhead trout. The Middle Fork Eel supports between one-third and one-half of California's entire remaining summer-run steelhead trout population.
