This winter a series of strong storms hit California, causing extensive damage to roads, trails, infrastructure and ecosystems on California's national forests. This map will help you determine where road damage has occurred and how it might impact your plans to visit the national forest.
The map shows the damage of which we are aware. While the map is linked directly to the Forest Service database and is kept as current as possible, please contact your local Forest Service office for the most complete and up-to-date information on road damage.
The Douglas-fir tussock moth (DFTM), Orgyia pseudotsugata, is an important defoliator of white fir in California. Outbreaks of the native insect occur somewhere in the state about every 10 years. These outbreaks arise abruptly, but generally subside within one to two years. White fir is the primary host, but other tree species may be defoliated during outbreaks. Defoliation by DFTM may weaken, kill, or top-kill trees. Heavily defoliated trees may experience reduced growth for several years post outbreak and be more susceptible to attacks by bark beetles. Ninety percent of mortality occurs in trees that are ≥ 90% defoliated, while trees with ≤ 50% defoliation rarely die. Top-kill follows a similar trend.
Pursuant to 16 USC 551 and 36 CFR 261.50 (b), and to provide for public safety, the following acts are prohibited on the Plumas national Forest. This is effective October 31, 2018 until November 30, 2019.
If a particular use is restricted or section of the forest is closed to the public, the Forest Orders and other information will be posted here. Restrictions and closures may take place for many reasons including fire danger, public safety, wildlife protection, road and campground upgrades, etc..
Please be aware of these alerts and notices because many unexpected situations can present difficult challenges for forest visitors.
