Snow Mountain Wilderness
The Snow Mountain Wilderness is a federally designated wilderness area located north of Santa Rosa, California, USA in the Mendocino National Forest. The U.S. Congress passed the California Wilderness Act of 1984 which created 23 new wilderness areas including Snow Mountain. It lies within the North Coast Range of mountains. Elevations are from to . The wilderness covers the crest of this North Coast Range mountain divide for and the summit area includes two peaks, East (7,050 ft) and West (7,021 ft). On October 17, 2006 the Northern California Coastal Wild Heritage Wilderness Act was signed into law (Public Law No: 109-362) which added to the Snow Mountain Wilderness. In July 2015, the area became part of Berryessa Snow Mountain National Monument. The Trough Fire burned of Snow Mountain Wilderness and national forest land in August 2001. More than 12 million dollars was spent to contain the wildfire even though most of the area was within the wilderness bou ...

Mendocino National Forest
The Mendocino National Forest is located in the Coastal Mountain Range in northwestern California and comprises 913,306 acres (3,696 km2). It is the only national forest in the state of California without a major paved road entering it. There are a variety of recreational opportunities — camping, hiking, mountain biking, paragliding, backpacking, boating, fishing, hunting, nature study, photography, and off-highway vehicle travel. The forest lies in parts of six counties. In descending order of forestland area they are Lake, Glenn, Mendocino, Tehama, Trinity, and Colusa counties. Forest headquarters are located in Willows, California. There are local ranger district offices in Covelo, Upper Lake, and Stonyford. Wilderness areas The forest includes four wilderness areas: * Sanhedrin Wilderness - * Snow Mountain Wilderness — * Yolla Bolly-Middle Eel Wilderness — (partly in Trinity NF, Six Rivers NF, or on BLM land) * Yuki Wilderness - (partly ...

Eel River (California)
The Eel River ( Wiyot: ''Wiya't''; Cahto: ''Taanchow''; Northern Pomo: ''ch'idiyu'') is a major river, about long, of northwestern California. The river and its tributaries form the third largest watershed entirely in California, draining a rugged area of in five counties. The river flows generally northward through the Coast Ranges west of the Sacramento Valley, emptying into the Pacific Ocean about downstream from Fortuna and just south of Humboldt Bay. The river provides groundwater recharge, recreation, and industrial, agricultural and municipal water supply.William M. Brown and John R. RitterSediment transport and Turbidity in the Eel River Basin, 1971, prepared in cooperation with the California Department of Water Resources, 67 pages The Eel River system is among the most dynamic in California because of the region's unstable geology and the influence of major Pacific storms. The discharge is highly variable; average flows in January and February are over 100 tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Lion
The cougar (''Puma concolor'') is a large cat native to the Americas. Its range spans from the Canadian Yukon to the southern Andes in South America and is the most widespread of any large wild terrestrial mammal in the Western Hemisphere. It is an adaptable, generalist species, occurring in most American habitat types. This wide range has brought it many common names, including puma, mountain lion, catamount and panther (for the Florida sub-population). It is the second-largest cat in the New World, after the jaguar (''Panthera onca''). Secretive and largely solitary by nature, the cougar is properly considered both nocturnal and crepuscular, although daytime sightings do occur. Despite its size, the cougar is more closely related to smaller felines, including the domestic cat (''Felis catus'') than to any species of the subfamily Pantherinae. The cougar is an ambush predator that pursues a wide variety of prey. Primary food sources are ungulates, particularly deer, but ...

American Black Bear
The American black bear (''Ursus americanus''), also called simply a black bear or sometimes a baribal, is a medium-sized bear endemic to North America. It is the continent's smallest and most widely distributed bear species. American black bears are omnivores, with their diets varying greatly depending on season and location. They typically live in largely forested areas, but will leave forests in search of food, and are sometimes attracted to human communities due to the immediate availability of food. The International Union for Conservation of Nature (IUCN) lists the American black bear as a least-concern species, due to its widespread distribution and a large population estimated to be twice that of all other bear species combined. Along with the brown bear (''Ursus arctos''), it is one of only two modern bear species not considered by the IUCN to be globally threatened with extinction. Taxonomy and evolution Despite living in North America, American black bears are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example ''Cytisus aeolicus'' is an endemite of the Italian flora. ''Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black-tailed Deer
Two forms of black-tailed deer or blacktail deer that occupy coastal woodlands in the Pacific Northwest of North America are subspecies of the mule deer (''Odocoileus hemionus''). They have sometimes been treated as a species, but virtually all recent authorities maintain they are subspecies.Novak, R. M. (1999). ''Walker's Mammals of the World.'' 6th edition. Heffelfinger, J.

Mountain Mahogany
''Cercocarpus'', commonly known as mountain mahogany, is a small genus of at least nine species of nitrogen-fixing flowering plants in the rose family, Rosaceae. They are native to the western United States and northern Mexico, where they grow in chaparral and semidesert habitats and climates, often at high altitudes. Several are found in the California chaparral and woodlands ecoregion. The classification of ''Cercocarpus'' within the Rosaceae has been unclear. The genus has been placed in the subfamily Rosoideae, but is now placed in subfamily Dryadoideae. Members of the genus are deciduous shrubs or small trees, typically reaching heights of 3–6 m (9–18 ft) tall, but exceptionally up to 13 m (40 ft) high. '' C. montanus'' usually remains under 1 m (3 ft) high because of incessant browsing by elk and deer. The name is derived from the Greek words κέρκος (''kerkos''), meaning "tail" and καρπός (''karpos''), meaning "fruit". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quercus Kelloggii
''Quercus kelloggii'', the California black oak, also known as Kellogg oak, is an oak in the red oak section (genus ''Quercus'', section ''Lobatae'', series ''Agrifoliae''), native to western North America. Although genetically separated from them for more than 20 million years, its leaves (though not its fruit) are remarkably similar in appearance to several other members of the red oak section including the red oak ('' Quercus rubra'') and the black oak (''Quercus velutina'') found in eastern and central North America. Description ''Quercus kelloggii'' typically grows from in height and from in diameter. Large trees may exceed in height and diameter, with the record holder measuring tall and thick (in the Siskiyou National Forest in Oregon). The species also grows in shrubby scrub-oak form on poor sites. In open areas, the crown is broad and rounded, with lower branches nearly touching the ground or forming a browse line. In closed stands, the crown is narrow and slen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Incense Cedar
''Calocedrus'', the incense cedar (alternatively spelled incense-cedar), is a genus of coniferous trees in the cypress family Cupressaceae first described as a genus in 1873. It is native to eastern Asia and western North America. The generic name ''Calocedrus'' means "beautiful cedar". Description The genus is related to the '' Thuja'', and has similar overlapping scale-leaves. ''Calocedrus'' differs from ''Thuja'' in the scale leaves being in apparent whorls of four (actually opposite decussate pairs like ''Thuja'', but not evenly spaced apart as in ''Thuja'', instead with the successive pairs closely then distantly spaced), and in the cones having just 2–3 pairs of moderately thin, erect scales, rather than 4–6 pairs of very thin scales in ''Thuja''. Species Extant Species Extinct Species Uses Bows and Arrows Incense cedar was one of the favored varieties of wood used to make bows by Native Americans in California.

Red Fir
''Abies magnifica'', the red fir or silvertip fir, is a western North American fir, native to the mountains of southwest Oregon and California in the United States. It is a high-elevation tree, typically occurring at elevation, though only rarely reaching tree line. The name red fir derives from the bark color of old trees. Description ''Abies magnifica'' is a large evergreen tree typically up to tall and trunk diameter, rarely to tall and diameter, with a narrow conic crown. The bark on young trees is smooth, grey, and has resin blisters, becoming orange-red, rough and fissured on old trees. The leaves are needle-like, long, glaucous blue-green above and below with strong stomatal bands, and an acute tip. They are arranged spirally on the shoot, but twisted slightly S-shaped to be upcurved above the shoot. The cones are erect, long, yellow-green (occasionally purple), ripening brown and disintegrating to release the winged seeds in fall. Varieties There are two, pe ...
