Sequoia National Forest

Sequoia National Forest

National forest in the U.S. state of California

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 (Sequoiadendron giganteum) trees which populate 38 distinct groves within the boundaries of the forest.

Quick Facts Location, Nearest city ...

The Giant Sequoia National Monument is located in the national forest. Other notable features include glacier-carved landscapes and impressive granite monoliths. The Needles are a series of granite spires atop a narrow ridge above the Kern River. Forest headquarters are located in Porterville, California. There are local ranger district offices in Dunlap, Kernville, Lake Isabella, and Springville.[2]

Geography

The Sequoia National Forest covers 1,193,315 acres (1,864.555 sq mi; 4,829.17 km2),[1] and ranges in elevation from 1,000 feet (300 m) in the foothills of the Sierra Nevada to over 12,000 feet (3,700 m). Its giant sequoia (Sequoiadendron giganteum) groves are part of its 196,000 acres (790 km2) of old growth forests. Other tree species include:[3]

The National Forest contains over 2,500 miles (4,000 km) of road and 850 miles (1,370 km) of trails, and hosts a number of camping and recreational facilities. The forest is adjacent to Sequoia and Kings Canyon National Parks.

Wilderness areas

Farewell Gap in the Golden Trout Wilderness

There are six wilderness areas within Sequoia NF that are part of the National Wilderness Preservation System. Some of these extend into neighboring National Forests, as indicated. Two of them also extend into land that is managed by the Bureau of Land Management.

Giant Sequoia National Monument

On April 15, 2000, President Bill Clinton proclaimed 328,000-acre (1,330 km2) of the Sequoia National Forest as the Giant Sequoia National Monument by Presidential Proclamation 7295, published in the Federal Register, Tuesday, April 25, 2000, Vol. 65, No. 80.

The monument is in two sections. The northern section surrounds General Grant Grove and other parts of Kings Canyon National Park and is administered by the Hume Lake Ranger District. The southern section is directly south of Sequoia National Park and is administered by the Western Divide Ranger District, surrounding the eastern half of the Tule River Indian Reservation.

The Needles

The Needles are a series of granite spires atop a narrow ridge above the Kern River.(36.1214°N 118.5044°W / 36.1214; -118.5044)[4]

History

Sequoia National Forest was established on July 1, 1908, from a portion of Sierra Forest Reserve. On March 2, 1909, Theodore Roosevelt added land by Presidential Proclamation.[5] On July 1, 1910 1,951,191 acres (7,896.19 km2) was removed from the forest to create the Kern National Forest.[6] This land was returned to Sequoia National Forest on July 1, 1915.

Fire impact

The Castle Fire in 2020 burned 131,087 acres (53,049 ha) in the forest, with 13,600 acres (5,500 ha) of giant sequoia groves burned[7][8] The fire swept through portions of the Dillonwood, Mountain Home, Alder Creek, Freeman Creek, McIntyre, and Wheel Meadow, Belknap, Burro Creek, Silver Creek, Middle Tule, Upper Tule, and Wishon Groves.[8] The fire burned at high intensity in 6,000 acres (2,400 ha) of sequoia groves:[8] high-intensity fire kills more than 90% of the giant sequoias in the area.[9] The number of mature Sequoia Trees that died overall is estimated at over 7500–10,600 mature trees, or over 10-14% of the species' population.[9][10]

The most intense previous fire in this area is dated to 1297 based on tree ring data. The McIntrye Grove, a short distance to the south from Cedar Slope, was heavily damaged. Near Sequoia Crest, one-third of the Alder Creek Grove of Giant Sequoia was severely damaged.[11] The large Stagg Tree in Alder Creek Grove was not impacted.[12] Other areas experienced "light fire" which is expected to be ecologically beneficial in the long run.

The Great Bonsai tree was destroyed in the Castle Fire of 2020

The following individual large Giant Sequoias in the forest have been reported to be damaged or destroyed in the Castle Fire:

  • Genesis tree (heavily damaged, previously the seventh-largest tree)[13]
  • Great Bonsai tree[13]
  • Summit Road tree (damaged, the 15th-largest tree)[13]
  • Waterfall tree (previously the sequoia with the largest ground perimeter[12]
  • Window tree[14]
  • The Patriarch tree[15]

The Windy Fire in 2021 burned over 97,528 acres (39,468 ha), including a large area in the forest.[16] A number of groves were completely within the fire perimeter, including the Cunningham, Deer Creek, Long Meadow, Packsaddle, Peyrone, Redhill, South Peyrone, and Starvation Creek Groves.[17] Over 3,000 acres (1,200 ha) of groves were within the fire perimeter.[17] Satellite image analysis showed that 50% of that area was burned at moderate or high intensity: over 1,000 giant sequoia were estimated to be destroyed in the forest.[17] Only four mature giant sequoia survived the fire in the Starvation Creek Grove.[18]

Giant sequoia groves

Further information: List of giant sequoia groves

The Sequoia National Forest has 34 giant sequoia groves.

  1. Indian Basin Grove (GSNM) A mid-size grove, mostly logged. It can be accessed by paved roads. The grove contains many young sequoias approaching diameters of up to 10 feet (3.0 m). 36°48′N 118°56′W 1800–2000 m.
  2. Converse Basin Grove (GSNM). Once the second-largest grove, but much logged around 1890–1900; However, nearly 100 widely scattered old-growth Giant Sequoias remain (apparently bypassed by the loggers), also good regrowth of younger trees. Home of the Boole Tree, which the loggers spared as it was by far the largest tree in the grove and is now identified as the sixth-largest tree by volume. Also home of the Chicago Stump, which is the remnant of the General Noble Tree that was cut for the 1893 World Columbian Exposition; the General Noble Tree was the second largest tree in the grove (after the Boole Tree) and it was the largest tree ever cut down. Although not among the very largest Giant Sequoias, the General Noble Tree was perhaps among the top 30 largest Giant Sequoias before it was cut. 36°48′N 118°58′W 1800–2000 m.
  3. Lockwood Grove (GSNM). 36°48′N 118°52′W 1700–1800 m.
  4. Monarch Grove (GSNM). Immediately north of the Agnew Grove, near Monarch Wilderness boundary. On Forest Service GSNM map.
  5. Evans Grove (GSNM). Partially logged, before 1920. 36°48'N 118°49'30"W 2050–2250 m.
  6. Agnew & Deer Meadow Grove (GSNM). 36°47′20″N 118°46′45″W 1950–2000 m.
  7. Cherry Gap Grove (GSNM). Logged. Located between Converse Basin Grove and General Grant Grove, near McGee Overlook (36°46′40″N 118°57′30″W). 2070 m. Cherry Gap Grove is a small sequoia grove of about thirty-five acres in Sequoia national forest; it was logged of all of its old growth sequoias.
  8. Abbott Creek Grove (GSNM). 36°46′N 118°58′W 1900 m. Listed by Rundel and Flint; very small (largely logged); too few trees to qualify as a grove according to Willard.
  9. Kennedy Grove (GSNM). 36°46′0″N 118°49′20″W 2050–2250 m. Contains the 13th largest giant sequoia in the world, The Ishi Giant.
  10. Little Boulder Creek Grove (GSNM). 36°45′10″N 118°49′0″W 2000 m.
  11. Boulder Creek Grove (GSNM). 36°45′N 118°49′W 2050 m.
  12. Landslide Grove (GSNM). 36°45′0″N 118°51′50″W 2050–2250 m.
  13. Bearskin Grove (GSNM). 36°45′0″N 118°54′40″W 1850–1900 m.
  14. Big Stump Grove (KCNP/GSNM). 36°43′N 118°58′W 1850 m.

  5. Burro Creek Grove (GSNM).
  6. Wishon Grove (GSNM). South of Silver Creek Grove. Included on Forest Service GSNM map.
  7. Alder Creek Grove (GSNM / private); also known as Hossack, Pixley, or Ross Creek Grove. Home of 'Alonzo Stagg', the fifth largest tree by volume. Also home to the Waterfall tree, which has the largest circumference and diameter at ground level of any sequoia.
