Bitterroot National Forest comprises 1.587 million acres (6,423 km²) in west-central Montana and eastern Idaho, of the United States. It is located primarily in Ravalli County, Montana (70.26% of the forest), but also has acreage in Idaho County, Idaho (29.24%), and Missoula County, Montana (0.49%).[1]
Founded in 1898, the forest is located in the Bitterroot and the Sapphire mountain ranges with elevations ranging from 2,200 feet (650 m) along the Salmon River in Idaho to 10,157 foot (3,100 m) Trapper Peak. Roughly half the forest (743,000 acres, 3,000 km²) make up part or all of three distinct Wilderness areas. These areas include the Anaconda-Pintler, Selway-Bitterroot and Frank Church River of No Return Wildernesses. The distinction is that in wilderness areas, no roads, logging, mining or other construction is permitted and all access must be done either on foot or horseback; even bicycles are not permitted. Hunting however is allowed forest-wide including wilderness areas.

The Lewis and Clark Expedition passed through parts of what are now forest lands in 1805. After the discovery of gold in Idaho and then Montana in the 1860s, numerous mining towns were built, some of which today are ghost towns. The Nez Perce National Historic Trail passes through a portion of the forest, following the route of the retreating Nez Perce on their historic path that led from Idaho to north central Montana in 1877. Heavy logging and other resource depletion beginning in the 1880s led conservationists to push for the preservation the forest.[2]
The Bitter Root Forest Reserve was established by the General Land Office on March 1, 1898 with 4,147,200 acres (16,783 km2). It was transferred to the U.S. Forest Service in 1906. On July 1, 1908 the name was changed to Bitterroot National Forest, with lands added from Big Hole National Forest and Hell Gate National Forest. Other lands were transferred from Biterroot to Beaverhead, Clearwater, Nez Perce and Salmon National Forests. On October 29, 1934 part of Selway National Forest was added.[3]
The forest is a combination of both grasslands and forested zones. Grazing rights are leased to private landowners in the lower altitudes where grasses and shrublands are dominant. Higher up, Douglas fir, larch, and lodgepole pine slowly give way to Engelmann Spruce and whitebark pine as the altitude increases. Above the treeline at 8,000 feet (2,400 m) the trees abruptly end and alpine flowers and grasses are found. A small grizzly bear population is located in the wilderness zones of the forest with black bear, mountain goat, bighorn sheep, elk and moose found forestwide. An active effort to reintroduce the grizzly bear to the region concluded in 2000 with a plan to release 25 bears into the wilderness zones over a five year period beginning in 2003.[4]
There are 1,600 mi (2,500 km) of trails and 18 improved campgrounds within the forest. Outstanding fishing is found in the dozens of rivers and streams and lakes. The forest headquarters is located in Hamilton, Montana. There are local ranger district offices in Darby, Stevensville, and Sula.[5] The largest nearby city is Missoula, Montana. The scenic Blodgett Canyon is but one of many steep canyons located in the forest. U.S. Highway 93 passes through portions of the forest.
Swanson (2011) examines the critical role of Guy M. Brandborg of the U.S. Forest Service, who was supervisor of the Bitterroot National Forest from 1935 to 1955. By insisting on selective cutting, his tried to protect the watersheds and wildlife habitats that are harmed by clear-cutting. After he retired in 1955 Brandborg denounced the Forest Service for deviating from his model of sustainable forestry. He launched a public attack, known as the "Bitterroot controversy." Brandborg lobbied to secure passage of the National Forest Management Act of 1976, that codified his ideals.
