From Wikipedia, the free encyclopedia
Eldorado National Forest is a U.S. National Forest located in the central
Sierra
Nevada Mountains in California, with a tiny portion extending
into Nevada. 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, Nevada, which
has an official 78 acres of forest land.[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 Toiyabe
National Forest, and to the south by the Stanislaus National Forest.
Forest headquarters are located in Placerville, California. There
are local ranger district offices in Camino,
Georgetown, Pioneer, and Pollock Pines.[2] The
forest was established on July 28, 1910 from a portion of Tahoe
National Forest and other lands.[3]
Climate
A Mediterranean climate extends
over most of the forest with warm, dry summers and cold, wet
winters.
- Annual precipitation: 40–70 inches (1,000 to 1,800 mm) on
average.
-
- Precipitation falls mainly from October through April.
- Temperature range: 0 °F (-20 °C) in winter to 100 °F (38 °C) in
the summer.
- Snow pack: 5 to 10 feet (1.5 to 3 m) on average, can be as high
as 15 feet (4.5 m).
-
- Snow is present from December to May at elevations above 6,000
feet (1,800 m).
Elevation
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.
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.
- Gross area: 786,994 acres (3,185 km²)
- Other ownership: 190,270 acres (770 km²)
- Net area: 596,724 acres (2,415 km²)
Vegetation
The principle vegetative types found on the Forest are woodland,
chaparral, mixed conifer,
true fir, and subalpine. A wide variety of hardwoods, brush, grasses, and forbs are mixed in with each of these forest
types.
Some 122,000 acres (49,000 ha) of old-growth
forests have been identified here, with Sierra Nevada mixed
conifer forests (Coast Douglas-fir (Pseudotsuga
menziesii var. menziesii), Ponderosa Pine (Pinus
ponderosa), and White Fir (Abies concolor)), Lodgepole Pine
(Pinus contorta) forests, and Red Fir (Abies
magnifica) forests the most common types[4
].
The major commercial Forest species are White Fir, Red Fir,
Ponderosa Pine, Jeffrey pine, Sugar Pine, Douglas Fir, and Incense
Cedar.
Water
Water is a major resource of the Eldorado National Forest. The
forest receives about 56 inches (1.4 m) of precipitation annually.
Average annual runoff is about 29 inches (737 mm). This is
equal to an annual water yield of 2.4 acre-feet per acre
(737,000 m³/km²); therefore National Forest lands yield an
estimated 1,444,000 acre-feet (1.8 km³) annually.
- 611 miles (983 km) of fishable streams in four major drainage systems: Middle
Fork of the American River (including the Rubicon), South Fork of
the American River, Cosumnes River, and North Fork of the Mokelumne
River.
- 297 lakes and reservoirs (including both public and
private land), which total 11,994 acres (48.5 km²). 11 large
reservoirs account for 9,000 acres (36 km²). The rest are
mostly small, high mountain lakes.
Transportation
The Eldorado has a high density transportation system containing
2,367 miles (3809 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 another 400 miles (640 km) of private
roads within the Forest boundary.
