Pacific Temperate Rain Forests
The Pacific temperate rainforests of western North America is the largest temperate rain forest region on the planet as defined by the World Wildlife Fund (other definitions exist). The Pacific temperate rainforests lie along the western side of the Pacific Coast Ranges along the Pacific Northwest Coast of North America from the Prince William Sound in Alaska through the British Columbia Coast to Northern California, and are part of the Nearctic realm, as also defined by the World Wildlife Fund. The Pacific temperate rain forests are characterized by a high amount of rainfall, in some areas more than per year and moderate temperatures in both the summer and winter months (). This ecoregion is a subregion of the Cascadia bioregion. These rainforests occur in a number of ecoregions, which vary in their species composition, but are predominantly of conifers, sometimes with an understory of broadleaf trees, ferns and shrubs. In the WWF's system, the ecoregions of the Paci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northern Pacific Coastal Forests
The Northern Pacific coastal forests are temperate coniferous forest ecoregion of the Pacific coast of North America. It occupies a narrow coastal zone of Alaska, between the Pacific Ocean and the northernmost Pacific Coast Ranges, covering an area of 23,300 square miles (60,400 square kilometers), extending from the Alexander Archipelago in southeast Alaska along the Gulf of Alaska to the western Kenai Peninsula and eastern Kodiak Island. The Pacific Coastal Mountain icefields and tundra ecoregion lies inland, at higher elevations in the Coast Mountains. The ecoregion receives high rainfall, which varies considerably based on exposure and elevation. It contains a quarter of the world's remaining temperate rain forest. Flora Conifers are the characteristic trees, and the predominant species are Sitka spruce ''( Picea sitchensis)'', western hemlock ''(Tsuga heterophylla)'', and mountain hemlock ''( Tsuga mertensiana)'', together with shore pine ''( Pinus contorta)'', western r ...

List Of Superlative Trees
The world's superlative trees can be ranked by any factor. Records have been kept for trees with superlative height, trunk diameter or girth, canopy coverage, airspace volume, wood volume, estimated mass, and age. Tallest The heights of the tallest trees in the world have been the subject of considerable dispute and much exaggeration. Modern verified measurements with laser rangefinders or with tape drop measurements made by tree climbers (such as those carried out by canopy researchers), have shown that some older tree height measurement methods are often unreliable, sometimes producing exaggerations of 5% to 15% or more above the real height. Historical claims of trees growing to , and even , are now largely disregarded as unreliable, and attributed to human error. The following are the tallest reliably measured specimens from the top 10 species. This table shows only currently standing specimens: Tallest historically Despite the high heights attained by trees nowada ...

Shore Pine
''Pinus contorta'', with the common names lodgepole pine and shore pine, and also known as twisted pine, and contorta pine, is a common tree in western North America. It is common near the ocean shore and in dry montane forests to the subalpine, but is rare in lowland rain forests. Like all pines (member species of the genus ''Pinus''), it is an evergreen conifer. Description Depending on subspecies, ''Pinus contorta'' grows as an evergreen shrub or tree. The shrub form is krummholz and is approximately high. The thin and narrow-crowned tree can grow high and achieve up to in diameter at chest height. The ''murrayana'' subspecies is the tallest. The crown is rounded and the top of the tree is flattened. In dense forests, the tree has a slim, conical crown. The formation of twin trees is common in some populations in British Columbia. The elastic branches stand upright or overhang and are difficult to break. The branches are covered with short shoots that are easy to remove. ...

Western Redcedar
''Thuja plicata'' is an evergreen coniferous tree in the cypress family Cupressaceae, native to western North America. Its common name is western redcedar (western red cedar in the UK), and it is also called Pacific redcedar, giant arborvitae, western arborvitae, just cedar, giant cedar, or shinglewood. It is not a true cedar of the genus ''Cedrus''. Description ''Thuja plicata'' is a large to very large tree, ranging up to tall and in trunk diameter. Trees growing in the open may have a crown that reaches the ground, whereas trees densely spaced together will exhibit a crown only at the top, where light can reach the leaves. The trunk swells at the base and has shallow roots. The bark is thin, gray-brown and fissured into vertical bands. As the tree ages, the top is damaged by wind and replaced by inferior branches. The species is long-lived; some trees can live well over a thousand years, with the oldest verified aged 1,460. The foliage forms flat sprays with scale-like l ...

Coast Douglas-fir
''Pseudotsuga menziesii'' var. ''menziesii'', commonly known as Coast Douglas-fir, Pacific Douglas-fir, Oregon pine, or Douglas spruce, is an evergreen conifer native to western North America from west-central British Columbia, Canada southward to central California, United States. In Oregon and Washington its range is continuous from the Cascades crest west to the Pacific Coast Ranges and Pacific Ocean. In California, it is found in the Klamath and California Coast Ranges as far south as the Santa Lucia Mountains with a small stand as far south as the Purisima Hills, Santa Barbara County. In the Sierra Nevada it ranges as far south as the Yosemite region. It occurs from near sea level along the coast to in the California Mountains. Further inland, coast Douglas-fir is replaced by Rocky Mountain or interior Douglas-fir (''P. menziesii'' var. ''glauca''). Interior Douglas-fir intergrades with coast Douglas-fir in the Cascades of northern Washington and southern British Columbia. ...

Sequoia Sempervirens
''Sequoia sempervirens'' ()''Sunset Western Garden Book,'' 1995:606–607 is the sole living species of the genus '' Sequoia'' in the cypress family Cupressaceae (formerly treated in Taxodiaceae). Common names include coast redwood, coastal redwood, and California redwood. It is an evergreen, long-lived, monoecious tree living 1,200–2,200 years or more. This species includes the tallest living trees on Earth, reaching up to in height (without the roots) and up to in diameter at breast height. These trees are also among the oldest living things on Earth. Before commercial logging and clearing began by the 1850s, this massive tree occurred naturally in an estimated along much of coastal California (excluding southern California where rainfall is not sufficient) and the southwestern corner of coastal Oregon within the United States. The name sequoia sometimes refers to the subfamily Sequoioideae, which includes ''S. sempervirens'' along with '' Sequoiadendron'' ( ...

Sitka Spruce
''Picea sitchensis'', the Sitka spruce, is a large, coniferous, evergreen tree growing to almost tall, with a trunk diameter at breast height that can exceed 5 m (16 ft). It is by far the largest species of spruce and the fifth-largest conifer in the world (behind giant sequoia, coast redwood, kauri, and western red cedar), and the third-tallest conifer species (after coast redwood and coast Douglas fir). The Sitka spruce is one of the few species documented to exceed in height. Its name is derived from the community of Sitka in southeast Alaska, where it is prevalent. Its range hugs the western coast of Canada and the US, continuing south into northernmost California. Description The bark is thin and scaly, flaking off in small, circular plates across. The inner bark is reddish-brown. The crown is broad conic in young trees, becoming cylindric in older trees; old trees may not have branches lower than .

Northern California Coastal Forests
The Northern California coastal forests are a temperate coniferous forests ecoregion of coastal Northern California and southwestern Oregon. Setting The ecoregion covers , extending from just north of the California-Oregon border south, to southern Monterey County. The ecoregion rarely extends more than 65 km inland from the coast, narrower in the southernmost parts of the ecoregion. The ecoregion is a sub-ecoregion of the Pacific temperate rain forests ecoregion, which extends up the Pacific Coast to Kodiak Island in Alaska. The ecoregion lies close to the Pacific Ocean, and is kept moist by Pacific Ocean storms during the winter months, and by coastal fogs in the summer months. These factors keep the ecoregion cooler in the summer and warmer in the winter, as compared to ecoregions further inland. The ecoregion is also defined by the distribution of the Coast Redwood (''Sequoia sempervirens''), with isolated groves located in protected canyons as far south as Redwood Gulc ...

Klamath-Siskiyou Forests
The Klamath Mountains ecoregion of Oregon and California lies inland and north of the Coast Range ecoregion, extending from the Umpqua River in the north to the Sacramento Valley in the south. It encompasses the highly dissected ridges, foothills, and valleys of the Klamath and Siskiyou Mountains. It corresponds to the Level III ecoregion designated by the Environmental Protection Agency and to the Klamath-Siskiyou forests ecoregion designated by the World Wide Fund for Nature. The ecoregion, also known as a ''geomorphic province,'' was unglaciated during the Pleistocene epoch, when it served as a refuge for northern plant species. Its mix of granitic, sedimentary, metamorphic, and extrusive rocks contrasts with the predominantly volcanic rocks of the Cascades ecoregion to the northeast. The mild, subhumid climate of the region is characterized by a lengthy summer drought. It supports a mosaic of both northern Californian and Pacific Northwestern conifers and hardwoods. E ...
