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..
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.
Currently the Plumas National Forest has an extensive winter off-highway vehicle program that involves the grooming of a number of National Forest System roads for use by snowmobiles. Conflicts often arise when wheeled motor vehicles are driven on the groomed trails because the vehicles create ruts in the trail and damage the trail in and around the areas where they get stuck. Operators cause other resource damage when they attempt to get out, and create a hazard to snowmobilers. The damage that is left behind requires costly groomer and operator time to fix. In the past the Plumas National Forest OHV managers have determined that a Forest Order is necessary to provide for protection of natural resources and public safety during the winter season.
In the interest of public safety, the Plumas National Forest is implementing an order closing the travertine quarry within the Soda Rock Special Interest Area.
The travertine quarry encompasses 6.1 acres of the Soda Rock Special Interest Area. The quarry has not operated since April of 1997 and reclamation of the site has not been completed. With the rubble or debris left over from quarry operations, the high headwalls, and the abandoned equipment, the public should be excluded from this area until reclamation is complete.
