San Bernardino National Forest (BDF - Forest #12) "San Bernardino" KME 2-0

The Forest Reserve Act was passed in 1891, giving the president authority to "set apart and reserve, in any state or territory having public land bearing forests . . public reservations." From this act was born the San Bernardino Forest Reserve, which became the San Bernardino National Forest in 1907. The San Bernardino National Forest as public land was set aside for the conservation of natural resources such as trees, water, minerals, livestock range, recreation, or wildlife.

The San Bernardino National Forest encompasses 677,982 acres and is made up of two main divisions, the San Bernardino Mountains on the easternmost of the Transverse Ranges, and the San Jacinto and Santa Rosa Mountains on the northernmost of the Peninsular Ranges. Elevations range from 2,000 to 11,499 feet (600 to 3505 m). The forest includes five wilderness areas: San Gorgonio, Cucamonga, San Jacinto, Santa Rosa and Bighorn Mountain.

The Santa Rosa and San Jacinto Mountains National Monument is located on the southern portion of the Forest. The National Monument’s boundary encompasses about 280,000 acres, including 67,000 acres within the San Jacinto Ranger District of the San Bernardino National Forest, and 97,000 acres within the Bureau of Land Management’s California Desert Conservation Area. The National Monument includes two federal wilderness areas-- the Santa Rosa Wilderness and the San Jacinto Wilderness--as well as lands owned and administered by the Agua Caliente Band of Cahuilla Indians, California Department of Parks and Recreation, California Department of Fish and Wildlife, municipalities of the Coachella Valley and private landowners.

The forest contains an estimated 87,400 acres of old growth forest. The most common trees of this old growth are Douglas fir (Pseudotsuga menziesii var. menziesii), Ponderosa pine (Pinus ponderosa), White fir (Abies concolor), Jeffrey pine (Pinus jeffreyi) and Lodgepole pine (Pinus contorta).

The Forest is divided into the Frontcountry (District 3), Mountain Top (District 1) and San Jacinto (District 5) Ranger Districts. A consolidation reduced the number of districts from 5 to 3 in 1996. The Frontcountry District (Lytle Creek Ranger Station) is a combination of the former Cajon (D3 - Lytle Creek) and San Gorgonio (D4 - Mill Creek Ranger Station) districts. The Mill Creek ranger station is still being maintained and used for public information and as a work center. The Mountain Top District (Fawnskin Ranger Station) is a combination of the former Arrowhead (D1 - Skyforest Ranger Station) and the Big Bear District (D2 - Fawnskin) districts. The Skyforest Ranger Station is still being maintained as a fire station. The Forest Supervisor's Office is located in San Bernardino just west of the airport.

Most of the radios on the forest have the first 11 frequencies in common. Each ranger district works with different state and local agencies so their channel lineups will be different. For example the Frontcountry Ranger District borders the direct protection area of the Cal Fire San Bernardino Unit and the San Jacinto Ranger District borders the direct protection of the Cal Fire Riverside Unit. Many fires start out in a local jurisdiction, move uphill into Cal Fire protected land and eventually to the National Forest. The San Bernardino National Forest has a Forest Net, Admin Net and a Service Net, the latter being shared between the Angeles, San Bernardino and Cleveland National Forests. The Forest Net is the only net with the capability for direct or simplex communication. Two channels allow repeater communication with the Angeles and Cleveland National Forests.


Non fire personnel on this forest use the function name, district number, position number identifier system. It is unknown what digit the employees of the Forest Supervisor's Office use. The San Bernardino National Forest is dispatched by the San Bernardino Federal Interagency Communications Center located in the Forest Supervisor's Office. This is the most active federal land management dispatch facility in the U.S. It provides all risk, 24 hour per day, 365 day dispatching for the San Bernardino National Forest, the BLM California Desert District, Joshua Tree National Park, Mojave National Preserve, and Death Valley National Park each of which host heavy recreation use, not only in the summer, but in the winter as well; and the BIA Southern California Agency, a group of small Indian Reservations. It also provides night coverage for the Inyo National Forest. The area served by the FICC covers approximately 30 million acres in five separate counties, reaching to the Arizona, Nevada and Mexico borders. These are the resources the center dispatches: 100 + Law Enforcement Officers, 7 Special Agents, 35 Fire Stations, 7 Active Fire Lookouts, 20 Fire Prevention Units, 6 Hand Crews, 1 Fuels Crew, 3 Helicopters, 2 Air Tankers, 1 Helitanker, 1 Air Attack, 1 LE Patrol Plane, 1 Dozer and 1 Air Tanker Base. Law enforcement activities tend to be busiest in the winter and spring, and fire activities are busiest in the summer and fall months. The identifier for the federal center is "San Bernardino."
