Context_1 : Trinity National Forest was established as the Trinity Forest Reserve by the U.S. Forest Service in California on April 26, 1905 with 1243042 acre . It became a National Forest on March 4, 1907. On July 1, 1908 it gave up some acreage to California National Forest. In 1954 it was combined administratively with Shasta National Forest to create Shasta-Trinity National Forest. Trinity National Forest is located overwhelmingly in Trinity County, which has 89.46% of its acreage. In descending order of land area the rest of the counties are Tehama with 7.37%, Shasta with 2.93%, and Humboldt with 0.23%. There are local ranger district offices in Hayfork and Weaverville. Its administrative offices reside in Redding, as part of the combined Shasta-Trinity National Forest. As of 30 September 2008, the Forest has an area of 1,043,677 acres (4,223.61km), comprising 47.23% of the combined Shasta-Trinity's total 2,209,832 acres (8,942.87km). Context_2 : Bridger National Forest was first established by the U.S. Forest Service on July 1, 1911 in Wyoming with 577580 acre from part of Bonneville National Forest. On May 14, 1923 Bridger was transferred Wyoming National Forest, and the name was discontinued. On March 10, 1943 Wyoming was renamed Bridger. In 1973 Bridger National Forest was administratively combined with Teton National Forest, creating Bridger-Teton National Forest. In descending order of land area, Bridger National Forest lands are located in Sublette, Lincoln, Fremont, and Teton counties. There are local ranger district offices in Afton, Big Piney, Kemmerer, and Pinedale. Its administrative headquarters reside in Jackson, Wyoming as part of the combined Bridger-Teton National Forest. Its current area of 1,736,075 acres (7,025.65 km) represents 51.02% of the combined Bridger-Teton's area of 3,402,644 acres (13,770.01 km). The forest includes all of the National Wilderness Preservation System's officially designated Bridger Wilderness. Context_3 : Snoqualmie National Forest is a United States National Forest in the State of Washington. It was established on 1 July 1908, when an area of 961,120 acres (3,889.52 km) was split from the existing Washington National Forest. Its size was increased on 13 October 1933, when a part of Rainier National Forest was added. In 1974 Snoqualmie was administratively combined with Mount Baker National Forest to make Mount Baker-Snoqualmie National Forest. In descending order of land area, Snoqualmie National Forest lies in parts of King, Snohomish, Pierce, and Kittitas counties. There are local ranger district offices in North Bend and Skykomish. Its main base is in Everett, Washington. As of 30 September 2007, it had an area of 1,258,167 acres (5,091.62 km), representing about 49 percent of the combined forest's total acreage. Context_4 : The Gila National Forest is a protected national forest in New Mexico in the southwestern part of the United States established in 1905. It covers approximately 2710659 acre of public land, making it the sixth largest National Forest in the continental United States. The Forest also manages that part of the Apache National Forest that is in New Mexico which totals an additional 614,202 acres for a total of 3.3 million acres managed by the Gila National Forest. Part of the forest, the Gila Wilderness, was established in 1924 as the first designated wilderness reservation by the U.S. federal government. Aldo Leopold Wilderness and the Blue Range Wilderness are also found within its borders. (The Blue Range Primitive Area lies within Arizona in the neighboring Apache National Forest.) Context_5 : The Preserve at Sharp Mountain (also called The Sharp Mountain Preserve) is a nature-based community located near Jasper, Georgia in Pickens County. It is one of three mountain communities in Pickens County, and the only one dedicated to maintaining its natural amenities. There are 12 mi of paved roads running through the community, but the population density is intentionally low (approximately 300 lots over 1600 acre ranging in size from a minimum of 3 acre to a maximum of 37 acres.) The Preserve at Sharp Mountain was named the "Best Community for Outdoor Lovers" by Pinnacle Living magazine, Unlike many planned communities, the Preserve at Sharp Mountain does not have swimming pools and tennis courts with club houses or golf courses. Instead, the Preserve at Sharp Mountain offers many acres of green space, hiking and nature trails, a nature pavilion, waterfalls, a bird sanctuary, a butterfly garden and various nature parks. The community is gated to restrict use of its 12 mi of privately owned roads to those living in the community. The Preserve at Sharp Mountain was developed by Four Seasons originally, which later became Naterra Land. Naterra's stated goal in all of its projects is "to better connect people with nature." Naterra Land sold out all of its inventory in the Preserve, and control of the community is now governed by a Property Owners' Association (POA). In 2011, the Preserve Association switched from being an HOA (Home Owners' Association) to being a POA (Property Owners' Association), each being viewed differently under Georgia law. In 2008 the Preserve became a recognized member of the national Firewise communities program and is one of the 13 in Georgia. Context_6 : The Coconino National Forest is a 1.856-million acre (751,000 ha) United States National Forest located in northern Arizona in the vicinity of Flagstaff. Originally established in 1898 as the "San Francisco Mountains National Forest Reserve", the area was designated a U.S. National Forest in 1908 when the San Francisco Mountains National Forest Reserve was merged with lands from other surrounding forest reserves to create the Coconino National Forest. Today, the Coconino National Forest contains diverse landscapes, including deserts, ponderosa pine forests, flatlands, mesas, alpine tundra, and ancient volcanic peaks. The forest surrounds the towns of Sedona and Flagstaff and borders four other national forests; the Kaibab National Forest to the west and northwest, the Prescott National Forest to the southwest, the Tonto National Forest to the south, and the Apache-Sitgreaves National Forest to the southeast. The forest contains all or parts of ten designated wilderness areas, including the Kachina Peaks Wilderness, which includes the summit of the San Francisco Peaks. The headquarters are in Flagstaff. There are local ranger district offices in Flagstaff, Happy Jack, and Sedona. Context_7 : The Cibola National Forest (pronounced SEE-bo-lah) is a 1,633,783 acre (6,611.7 km2) United States National Forest in New Mexico, USA. The name Cibola is thought to be the original Zuni Indian name for their pueblos or tribal lands. The name was later interpreted by the Spanish to mean, "buffalo." The forest is disjointed with lands spread across central and northern New Mexico, west Texas and Oklahoma. The Cibola National Forest is divided into four Ranger Districts: the Sandia, Mountainair, Mt. Taylor, and Magdalena. The Forest includes the San Mateo, Magdalena, Datil, Bear, Gallina, Manzano, Sandia, Mt. Taylor, and Zuni Mountains of west-central New Mexico. The Forest also manages four National Grasslands that stretch from northeastern New Mexico eastward into the Texas Panhandle and western Oklahoma. The Cibola National Forest and Grassland is administered by Region 3 of the United States Forest Service from offices in Albuquerque, New Mexico. Elevation ranges from 5,000ft (1,500 m) to 11,301ft (3,445 m). (The preceding figures do not include any of the four National Grasslands mentioned below, which are detailed in their individual articles.) The descending order of Cibola National Forest acres (not counting the three Grassland areas) by county are: Socorro, Cibola, McKinley, Catron, Torrance, Bernalillo, Sandoval County, New Mexico, Lincoln, Sierra, and Valencia counties in New Mexico. The Cibola National Forest currently has 137,701 acres designated as Wilderness. In addition to these acres, it has 246,000 acres classified as Inventoried Roadless Areas pursuant to the Roadless Area Conservation Rule. Context_8 : The Palouse Forest Reserve and after March 4, 1907, the Palouse National Forest was established by Presidential Proclamation (34 U.S. Statutes at Large 3293) on March 2, 1907 and was one of President Theodore Roosevelt's Midnight forests, created before the federal law banning new forest reserves in six western states, including Idaho, became effective. The conventional wisdom has the name 'palouse' being derived from the French term for the large treeless plain region in eastern Washington stretching into Idaho: the Palouse, a word meaning grassy spot or place. However, Boone says that the name could originate from the name of a major village of Palouse Indians, Palus, located at the confluence of the Palouse and Snake Rivers. 'Palus' is the Sachapin Indian word for "something sticking down in the water," in this case the something was a large rock, thought to be a beaver's heart, and which had an important religious significance for the Palouse Indians. The Palouse National Forest had its administrative headquarters in the town of Wallace, Idaho for its 15-month existence and was administered by the U.S. Forest Service with 194404 acre . With the issuance of Executive Order 843 by President Roosevelt on June 26, 1908, with an effective date of July 1, 1908, the entire forest was absorbed by the Coeur d'Alene National Forest and the area ceased to be an independently administered national forest. The lands of the former Palouse National Forest were then administered as part of the Coeur d'Alene National Forest for three years before being combined with other lands to establish the St. Joe National Forest on July 1, 1911. The area of the former Palouse National Forest formed the western portion of the St. Joe National Forest. Once transferred in 1911, the area of the Palouse National Forest became the Palouse Ranger District of the St. Joe National Forest and is still considered part of the St. Joe National Forest. However, it has been administered by the Clearwater National Forest since the 1973 administrative merger of the Kaniksu National Forest, Coeur d'Alene, and St. Joe National Forests into the Idaho Panhandle National Forests. Context_9 : The Chattahoochee-Oconee National Forest in northern Georgia comprises two United States National Forests, the Oconee National Forest and Chattahoochee National Forest.
