The San Gabriel Wilderness Addition encompasses a portion of the West Fork San Gabriel River and its watershed, which is an important source of clean drinking water. The area’s north-facing slopes support one of the largest forests of big cone Douglas fir and live oaks in the region. An “Area of High Ecological Significance,” the addition provides critical habitat for Nelson’s bighorn sheep, San Gabriel mountain salamander, Santa Ana speckled dace, and California spotted owl. Outstanding recreational opportunities include hiking, fishing, and horseback riding.
