The Caribou Wilderness is a federally designated wilderness area created by the Wilderness Act of 1964 and is part of the National Wilderness Preservation System. It is located east of Redding in the state of California, USA. The Caribou Wilderness comprises 〔("Wilderness Acreage" ). Wilderness.net. accessed Dec.6, 2008〕 and is adjacent to the east side of Lassen Volcanic National Park. Although the park (which includes its own Lassen Volcanic Wilderness area) is surrounded by Lassen National Forest, it is managed separately by the National Park Service, whereas the U.S. Forest Service manages the wilderness. Elevations range from to . The terrain is a volcanic plateau with 75% covered by water and conifer forests and the remainder being barren rock such as cliff faces, talus slopes and cinder cones. Most of this area has been preserved since 1932 which makes the Caribou Wilderness one of the few remaining pristine forests of the California Cascade region. There are 23 named lakes, innumerable unnamed ponds and tarns, cinder cones and volcanic buttes within the wilderness. Although there are no year round surface streams, the area provides high quality water for the headwaters of the Susan River, and Bailey Creek, a tributary of the Feather River. The high point is Red Cinder (8,363 ft) located near the boundary between the wilderness and the park. Other peaks are North Caribou (7,785 ft), South Caribou ( 7,753 ft) and Black Butte in the northeast at 7,989 ft. Recreational activities include day hiking, backpacking, fishing, horseback riding, cross-country skiing, nature photography and rock climbing. The Forest Service encourages the practice of Leave No Trace principles of outdoor travel to minimize human impact on the environment. == Flora, fauna and fungi == The forest is lodgepole pine, Jeffrey pine, ponderosa pine, Douglas fir, white and red fir, western white pine, incense cedar, and hemlock. 21 of Caribou's lakes are stocked by air with rainbow trout. Black-tailed deer and black bears along with squirrels, chipmunks, and the protected (from hunting) pine marten live here. There are bald eagles and ospreys overhead, mergansers and grebes on the ponds and lakes. Much smaller in size, but critically important to the forest ecosystem are the fungi. The cup fungus, for instance, can be found in the Caribou. As the sanitary agents of the forest that consume dead organic matter, fungi spread on the floor of a conifer area. Fungal spores blow in on the winds and take up residence at the foot of trees. One type, called the king bolete, is the edible mushroom most sought. Not all fungi have a symbiotic relationship with the trees, some fungi are parasitic, causing heartwood rot. Along some trails in the Caribou, hikers will see a timber-destroying (causes brown rot) 〔Brown rot and white rot are the two general types of wood decay caused by fungi. Brown rot results from the action of fungi which destroy the cellulose and leave a dry, brown, crumbly mass of lignin constituents of wood. Wood containing brown rot, even in the earliest visible stages of decay, is so weakened that it will fail in use and must be discarded. Since the cellulose fibers are affected, the value of wood for pulp is lost when brown rot occurs.

An interesting aspect of red-belt fomes is that it has a laquared feel if touched. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Caribou Wilderness」の詳細全文を読む スポンサード リンク
