Eldorado National Forest is a U.S. National Forest located in the central Sierra Nevada mountain range, in eastern California.

Most of the forest (72.8%) lies in El Dorado County. In descending order of land area the others counties are: Amador, Alpine, and Placer counties in California; and Douglas County in Nevada with 78 acres (320,000 m2). [1] The forest is bordered on the north by the Tahoe National Forest, on the east by the Lake Tahoe Basin Management Unit, on the southeast by the Humboldt-Toiyabe National Forest, and to the south by the Stanislaus National Forest.

Eldorado National Forest headquarters are located in Placerville, California. There are local ranger district offices in Camino, Georgetown, Pioneer, and Pollock Pines. [2]

Land ownership

A complicated ownership pattern exists. The parcels of Other Ownership (private or other Agency land) are mostly isolated and surrounded on all sides by government land. An opposite pattern occurs outside of the Forest Boundary where several small scattered pieces of National Forest lands are separated from the main body and surrounded by lands of Other Ownership.


The Forest ranges in elevation from 1,000 feet (300 m) in the foothills to more than 10,000 feet (3,000 m) above sea level along the Sierra crest. The mountainous topography is broken by the steep canyons of the Mokelumne, Cosumnes, American, and Rubicon rivers. Plateaus of generally moderate relief are located between these steep canyons.

Wilderness areas

The Desolation Wilderness is located within the forest's boundaries, as is most of the Mokelumne Wilderness (which extends into neighboring Stanislaus National Forest and Humboldt-Toiyabe National Forest).

A cool montane version of Mediterranean climate extends over most of the forest with warm, dry summers and cold, wet winters.



A wide variety of hardwoods, conifers, shrubs, native grasses, and forbs are represented in the various Eldorado National Forest ecosystems.

The principal plant communities found here are:

Old-growth forests totaling 122,000 acres (49,000 ha) have been identified in the Eldorado National Forest, consisting of: [3]

Sierra Nevada mixed conifer forests


The major commercial Forest species are White Fir, Red Fir, Ponderosa Pine, Jeffrey pine, Sugar Pine, Douglas Fir, and Incense Cedar.


Water is a major resource of the Eldorado National Forest. The forest receives about 56 inches (1,400 mm) of precipitation annually. Average annual runoff is about 29 inches (740 mm). This is equal to an annual water yield of 2.4 acre-feet (3,000 m3) per acre (737,000 m³/km²); therefore National Forest lands yield an estimated 1,444,000 acre-feet (1.781×109 m3) annually.


The Eldorado National Forest has a high density of transportation routes, with 2,367 miles (3,809 km) of roads, and 349 miles (562 km) of trails. Roads under Forest Service jurisdiction total 2,158 miles (3,473 km). There are 209 miles (336 km) of county roads, and 400 miles (640 km) of private roads within the National Forest boundaries.


The forest was established on July 28, 1910 from a portion of Tahoe National Forest and other lands. [4]

Sierra National Forest

Sierra National Forest is a U.S. National Forest located on the western slope of central Sierra Nevada in Central California and bounded on the northwest by Yosemite National Park and the south by Kings Canyon National Park. The forest is known for its mountain scenery and beautiful lakes. Forest headquarters are located in Clovis, California. There are local ranger district offices in North Fork and Prather.

Stanislaus National Forest

Stanislaus National Forest is a U.S. National Forest which manages 898,099 acres of land in four counties in the Sierra Nevada in Northern California. It was established on February 22, 1897, making it one of the oldest national forests. It was named after the Stanislaus River.

Ecology of the Sierra Nevada

The ecology of the Sierra Nevada, located in the U.S. states of California and Nevada, is diverse and complex: the plants and animals are a significant part of the scenic beauty of the mountain range. The combination of climate, topography, moisture, and soils influences the distribution of ecological communities across an elevation gradient from 500 to 14,500 feet. Biotic zones range from scrub and chaparral communities at lower elevations, to subalpine forests and alpine meadows at the higher elevations. Particular ecoregions that follow elevation contours are often described as a series of belts that follow the length of the Sierra Nevada. There are many hiking trails, paved and unpaved roads, and vast public lands in the Sierra Nevada for exploring the many different biomes and ecosystems.

San Francisco Peaks

The San Francisco Peaks are a volcanic mountain range in San Francisco volcanic field in north central Arizona, just north of Flagstaff and a remnant of the former San Francisco Mountain. The highest summit in the range, Humphreys Peak, is the highest point in the state of Arizona at 12,633 feet (3,851 m) in elevation. The San Francisco Peaks are the remains of an eroded stratovolcano. An aquifer within the caldera supplies much of Flagstaff's water while the mountain itself is in the Coconino National Forest, a popular recreation site. The Arizona Snowbowl ski area is on the western slopes of Humphreys Peak, and has been the subject of major controversy involving several tribes and environmental groups.

Sequoia National Forest

Sequoia National Forest is located in the southern Sierra Nevada mountains of California. The U.S. National Forest is named for the majestic Giant Sequoia trees which populate 38 distinct groves within the boundaries of the forest.

It is located in parts of six counties: Sierra, Placer, Nevada, Yuba, Plumas and El Dorado. The forest has a total area of 871,495 acres. Its headquarters is in Nevada City, California. There are local ranger district offices in Camptonville, Foresthill, Sierraville and Truckee.

Ed Z'berg Sugar Pine Point State Park is a state park in California in the United States. It occupies nearly two miles of the western shore of Lake Tahoe and a total of about 1,000 hectares of forested mountains in El Dorado County.

Mixed coniferous forest is a vegetation type dominated by a mixture of broadleaf trees and conifers. It is generally located in mountains, below the upper montane vegetation type.

Upper montane forest

The upper montane forest is a vegetation type generally found above the mixed coniferous forest and below the subalpine forest vegetation types. Most of what grows in upper montane forests are conifers, because of the short growing season.

Sierra Nevada upper montane forest

The Sierra Nevada upper montane forest is a vegetation type found below the treeline in the United States Sierra Nevada range. It is generally located above the mixed coniferous forest and below the alpine zone. Overstory trees are typically cone shaped to shed the snow.
