Sierra National Forest is a U.S. National Forest located on the western slope of central Sierra Nevada in the state of California. The forest is known for its mountain scenery and natural resources. Forest headquarters are located in Clovis, California. There are local ranger district offices in North Fork and Prather.[1]



This was the second National Forest created in California and the largest at the time. It covered over six million acres (24,000 km²) of the Sierra Nevada and was about four times the average area of typical California National Forests. Originally it embraced parts of eight counties from Tuolumne on the north to Kern on the south and Mono and Inyo on the east. Initially its name was descriptive, but later when the Sierra was divided into different units this was no longer the case.

President Harrison proclaimed the Sierra Forest Reserve on February 14, 1893. Four years later the south half became a separate unit and was named Sierra South during the "forest reserves" era. This designation was dropped after the administrative transition to the National Forests on march 4th 1907. the Sequoia National Forest on july 1st 1908 Kings Canyon and Sequoia National Parks were established from this south portion of Sierra National Forest. also eastern portions of Sierra were used for the Inyo and Toiyabe National Forests as well as northern portions were uses for the Yosemite National Park and the Stanislaus National Forest.

The first timber sale on a California national forest took place in the Sierra NF by the General Land Office in 1899.[2]


Sierra covers in descending order of forestland area, the eastern portions of Fresno, Madera, and Mariposa counties, adjacent to the southern part of Yosemite National Park. It includes more than 1,300,000 acres (2,030 sq mi; 5,300 km2), at altitudes that range from 900 to 13,986 feet (274 to 4,263 m) in elevation. The terrain includes rolling, oak-covered foothills, heavily forested middle elevation slopes and the alpine landscape of the High Sierra.

The forest boundary's, starting clockwise at the intersections of the Merced River, The Sweetwater Creek and the HWY 140 then moving east following the Merced River canyon to the border with the Yosemite National Park Near El Protal, ca.. Then it follows the parks southern boundary till it reaches the Inyo National forest near Electra Pk. from there it travels south to its border with the Kings Canyon National park near Mt Goethe. from here it follows the parks Northern border both north then south to the Kings River near Deer Canyon. Then it moves down the Kings river canyon east, south of the river is the Sequoia National Forest. When it reaches Pine Flat lake near Trimmer, ca. it turns north towards Tollhouse, ca. and continues on to Auberry, ca. from there it moves on to North Fork, Ca. then west to form a small finger towards Coarsegold, ca. from there it travels north to Yosemite Forks, ca. from there it moves west towards Miami Mountain. then north to the Merced River.


The forest includes a number of scenic attractions, including Fresno Dome and Nelder Grove. Several reservoirs offer fishing, including Bass Lake, Wishon Reservoir, and Courtright Reservoir. Also, there are numerous hiking opportunities in wilderness areas: Ansel Adams, John Muir, Dinkey Lakes, Kaiser, and Monarch. It also has a ski area, Sierra Summit Ski Area, that operates under a special use permit.


The Sierra National Forest is located within the Pacific southwest region of the US Forest Service. The Forest is Divided into three Ranger Districts

Bass lake Ranger District is North and West of the San Joaquin River it's Ranger District office is located at 57003 Road 225 North Fork, California, CA 93643. there are 36 camp sites, 17 picnic sites, 7 Off Highway Vehicle Trails, 10 trails, it includes the Forest Service Offices of Eastwood at Hwy 168 and Kaiser Pass Road at Huntington Lake, Dinkey Creek in the area of, Oakhurst (41969 Hwy 41, Oakhurst, California 93644), and Mariposa (5158 Suite A Highway 140 Mariposa, California 95338) also The High Sierra visitor information Station near Mono Hot Springs on the Kaiser Pass Road and the Clover Meadow Wilderness Office in the area of.

High Sierra Ranger District South and East of the San Joaquin River it has it's Ranger District office out of Prather, California. This district contains 30 camp sites, 11 picnic sites, and 13 Off Highway Vehicle Trails.

Supervisor's Office (an administrative Unit) which contains the Forest Headquarters Located at 1600 Tollhouse Rd Clovis, California, 93611. two Community Visitor Centers: the Mariposa Interagency Visitor Center (5158 Highway 140 Mariposa, CA 95338) and the Yosemite Sierra Visitor Bureau (41969 Highway 41, Oakhurst, CA 93644). and the Fresno Air Attack Base which is co located with the Sierra National Forest Emergency Communications Center at 2307 and 2309 N Clovis ave. Fresno, California all on the Fresno Yosemite International Airport

In addition, the forest has a close relationship with the Teakettle Experimental Forest which is deep inside the forest and the San Joaquin Experimental Range which is just outside the forest boundary's. They both fall in the Pacific southwest Research Station which is based in Berkeley, California.[3]

Sierra Nation Forest Fire & Aviation Management


The ecology of the National Forest are typical for the western side of the southern Sierra Nevada: distributions of species are largely governed by climate, which is strongly dependent on altitude. The ecology can be described by biotic zones, which are marked by either an tree indicator species, or by a lack of trees. The biotic zones include the foothill woodland zone from 1,000 to 3,000 feet (300 to 910 m) (interior live oak), the lower montane zone from 3,000 to 7,000 feet (910 to 2,100 m) (Yellow pine), the upper montane zone from 7,000 to 9,000 feet (2,100 to 2,700 m) (Lodgepole pine/Red fir), the subalpine zone from 9,000 to 9,500 feet (2,700 to 2,900 m) (Whitebark pine), and the alpine zone from 9,500 feet (2,900 m) (above the tree line).[4]

In addition, some 383,000 acres (598 sq mi; 1,550 km2) of the forest are old growth, containing Lodgepole Pine (Pinus contorta), Red Fir (Abies magnifica).[5 ]
