Caribou–Targhee National Forest
# Caribou–Targhee National Forest

Caribou–Targhee National Forest is located in the states of Idaho and Wyoming, with a small section in Utah in the United States. The forest is broken into several separate sections and extends over 2.63 million acres (10,600 $km^2).$ To the east the forest borders Yellowstone National Park, Grand Teton National Park and Bridger–Teton National Forest. Most of the forest is a part of the 20-million-acre (81,000 $km^2)$ Greater Yellowstone Ecosystem.

## Description

Caribou and Targhee National Forests were combined from original forest lands created in 1891. Two designated wilderness areas are located in the easternmost sections of the forest, bordering on National Park lands. The 123,451-acre (500 $km^2)$ Jedediah Smith Wilderness is adjacent to Grand Teton National Park on the western slope of the Teton Range. Known for karst limestone formations, the wilderness has many caves and provides excellent views of the less often seen west face of the Teton peaks. The smaller 10,715-acre (43 $km^2)$ Winegar Hole Wilderness borders Yellowstone National Park and the John D. Rockefeller, Jr. Memorial Parkway, and was set aside primarily to protect prime grizzly bear habitat.

While western sections of the forest have a mixture of sagebrush and grasses, the higher elevations in the east support lodgepole pine, and numerous species of spruce and fir. In addition to grizzlies most of the major megafauna associated with Yellowstone National Park can be found in Caribou–Targhee National Forest. Mammalian species of black bear, wolf, elk, moose, mule deer, bison, cougar, and pronghorn have all been seen by visitors on forest lands. An active peregrine falcon recovery program was begun to return this bird species to some of their ancestral range. Cutthroat trout, brook trout and pike are found in the streams and lakes and the forest is considered one of the best fishing areas in the world for cutthroat trout.

Dozens of campgrounds and 1,600 miles (2,500 km) of trails allow access to much of the forest. There are two trails that access the high altitude Alaska Basin immediately west of the main Teton Range peaks and allow access to trails in Grand Teton National Park.

Caribou National Forest, the smaller and more southerly of the two, is located in southeastern Idaho, western Wyoming, and northern Utah, and has a total area of 987,221 acres (3,995 $km^2).$ There are local ranger district offices located in Malad City, Montpelier, Pocatello, and Soda Springs in Idaho.

The larger and more northerly Targhee National Forest is located in eastern Idaho and northwestern Wyoming, and has an area of 1,643,501 acres (6,651 $km^2).$ There are local ranger district offices located in Ashton, Driggs, Dubois, and Island Park in Idaho. In Island Park is Big Springs, a first-magnitude spring that is the source of the South Fork of Henrys Fork.

Linkage of limited habitat, through ecological corridors, is the current, most favored, method of effectively restoring native wildlife communities. Many such corridors have been identified where wildlife conservation is a concern. The montane nature of the Caribou National Forest and its juxtaposition make it a very important, fragile and unique link between the northern and southern Rocky Mountains. If restoration of native species is to be achieved throughout the wildlands of the American West, the Caribou will play an important role.

The combined Caribou–Targhee National Forest is managed by the Forest Service from offices in Idaho Falls, Idaho.
