Klamath National Forest (KNF - Forest #05) "Yreka" KMB 6-8-0

The Klamath National Forest encompasses nearly 1.7 million acres of land straddling the California and Oregon border with the majority in California and a small portion in Oregon. The Forest is divided into two sections separated by the Shasta Valley and the I-5 corridor. In the mountains to the west, the terrain is steep and rugged and is arguably the most rugged in the Pacific Southwest Region. The east-side has the relatively gentler, rolling terrain of volcanic origin. Here the Goosenest Ranger District also administers the Butte Valley National Grassland, the only National Grassland in Region 5. With elevations ranging from 450 to 8,900 feet above sea level, the Klamath National Forest is one of America’s most biologically diverse regions. It is situated in a transitional region between the hotter and drier areas to the south and the colder, wetter climate to the north. At the California-Oregon boundary the Klamath National Forest extends into Oregon and two small areas of the Rogue River-Siskiyou National Forest extend into California. The two forests are in two different Forest Service Regions, the Pacific Southwest and the Pacific Northwest and Forest Service Regions normally follow state lines with some exceptions. In this case the boundary is following the divide between the Klamath River and the Rogue River. When Regional, National Forest and Ranger District boundaries are drawn, an attempt is made to follow drainage or hydrological boundaries. In this way two units are not managing the same watershed. The desired outcome is to have boundaries that follow topographical, hydrological and ecological lines, rather than oft arbitrary political ones.

Old growth forest is estimated to cover some 168,295 acres of the Klamath The primary trees are Coast Douglas fir (Pseudotsuga menziesii var. menziesii), Tanoak (Lithocarpus densiflorus), Pacific madrone (Arbutus menziesii), Port Orford cedar (Chamaecyparis lawsoniana) and White Fir (Abies concolor).

The forest includes 5 Congressionally designated wilderness areas, Marble Mountain, Russian, Trinity Alps, Red Buttes and Siskiyou. In the lower elevations, you'll find park-like stands of Ponderosa Pines, while in the higher elevations, the Douglas fir, sub-alpine fir and mixed conifer stands beg to be explored. There are 200 miles of river system for rafting and 152 miles of wild and scenic rivers on the forest. The Forest also helps to meet local and national needs for timber, gold, and other natural resources. The forest is divided into the Oak Knoll (District 1), Happy Camp (District 2), Salmon River (District 4), Scott River (District 5) and Goosenest (District 7) Ranger Districts, with the Forest Supervisor's Office in Yreka. As of 2016, there is one district ranger for the Oak Knoll and Happy Camp Ranger Districts with the district office for the combination located in Happy Camp. The Salmon River and Scott River Ranger Districts has one district ranger who works from the district office in Fort Jones. The Klamath's Ukonom Ranger District is being administered by the Six Rivers National Forest from their Orleans Ranger District Office.

The Klamath National Forest's radio system is unique in two ways. First it has one mountain top remote base and base stations located at Ranger Stations, work centers, fire stations and such. The mountaintop base is at the Gunsight Peak Communications Site west of Yreka. The ground level remote base stations are located at: Oak Knoll Work Center, Happy Camp Ranger Station, Seiad Station, Happy Camp Helibase, Sawyers Bar Work Center, Scott River Ranger Station, Salmon River Ranger Station, and the Goosenest Ranger Station. There is information that seems to indicate that Yreka Dispatch remote controls one base station at each ranger station, and the work centers at Seiad, Oak Knoll and Sawyers Bar. These are likely linked via phone lines or by VoIP. The rugged terrain likely prevents Gunsight remote base being able to cover the entire forest.

Second, the Klamath National Forest has a separate repeater net for each of the 5 ranger districts on the forest. The Black Net covers the Oak Knoll Ranger District, the Orange Net is provided for the Happy Camp Ranger District, the Salmon Net is used on the Salmon River Ranger District, the Sage Net is assigned to Goosenest Ranger District and finally the River Net is for the Scott River Ranger District. A simplex channel is included for each net. The R5 project/fire net is not used on this forest due to conflicts with frequency use in the Pacific Northwest Region (R6 - Oregon and Washington).


The unit identifiers follow the function name, district, position number system. Common function names include resources, timber, recreation, wilderness, OHV (Off Highway Vehicle management) lands, special uses, range, wildlife, watershed, soils, fisheries, engineer, engineering, roads, O & M (Operations and Maintenance), ecology and possible additional. Not every forest uses all of these and some ID the same unit with a different name, example some forests call their O & M and roads units "engineering." The Yreka Interagency Dispatch Center provides dispatching services for the Klamath National Forest and is co-located with Cal Fire's Siskiyou Unit dispatch center at the Cal Fire Siskiyou Unit headquarters in Yreka. It is a 24 hour operation. The center's identifier is "Yreka".
