Areas that are closed for visitor use also include campgrounds, picnic areas, bathrooms, water stations, paved parking areas, and boat launch ramps, such as those at Pine Flat and Shaver Lakes.
Trails, trailheads and other general forest areas will continue to remain open, but the Forest Service asked those who wish to be outside to do so near their homes.
The department said it is working with state officials to develop a plan for reopening the sites.
