Pinus albicaulis, known by the common names whitebark pine, white bark pine, white pine, pitch pine, scrub pine, and creeping pine, is a conifer tree native to the mountains of the western United States and Canada, specifically subalpine areas of the Sierra Nevada, Cascade Range, Pacific Coast Ranges, Rocky Mountains, and Ruby Mountains. It shares the common name "creeping pine" with several other plants.
The tree line is the edge of a habitat at which trees are capable of growing and beyond which they are not. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions. The tree line is sometimes distinguished from a lower timberline, which is the line below which trees form a forest with a closed canopy.
Pinus flexilis, the limber pine, is a species of pine tree in the family Pinaceae that occurs in the mountains of the Western United States, Mexico, and Canada. It is also called Rocky Mountain white 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, it is an evergreen conifer.
The Rocky Mountains subalpine zone is the biotic zone immediately below tree line in the Rocky Mountains of North America. In northern New Mexico, the subalpine zone occupies elevations approximately from 9,000 to 12,000 feet ; while in northern Alberta, the subalpine zone extends from 1,350 to 2,300 metres.
The Sierra Nevada subalpine zone refers to a biotic zone below treeline in the Sierra Nevada mountain range of California, United States. This subalpine zone is positioned between the upper montane zone at its lower limit, and tree line at its upper limit.
Spruce-pine-fir (SPF) is a classification of lumber that can be traded on commodities exchanges.
The biogeoclimatic zones of British Columbia are units of a classification system used by the British Columbia Ministry of Forests for the Canadian province's fourteen different broad, climatic ecosystems. The classification system, termed Biogeoclimatic Ecosystem Classification, exists independently of other ecoregion systems, one created by the World Wildlife Fund and the other in use by Environment Canada, which is based on one created by the Commission for Environmental Cooperation (CEC) and also in use by the US Environmental Protection Agency (EPA). The system of biogeoclimatic ecosystem classification was partly created for the purpose of managing forestry resources, but is also in use by the British Columbia Ministry of Environment and Climate Change Strategy and other provincial agencies. A biogeoclimatic zone is defined as "a geographic area having similar patterns of energy flow, vegetation and soils as a result of a broadly homogenous macroclimate."
The Ecology of the North Cascades is heavily influenced by the high elevation and rain shadow effects of the mountain range. The North Cascades is a section of the Cascade Range from the South Fork of the Snoqualmie River in Washington, United States, to the confluence of the Thompson and Fraser Rivers in British Columbia, Canada, where the range is officially called the Cascade Mountains but is usually referred to as the Canadian Cascades. The North Cascades Ecoregion is a Level III ecoregion in the Commission for Environmental Cooperation's classification system.
The Alberta–British Columbia foothills forests are a temperate coniferous forests ecoregion of Western Canada, as defined by the World Wildlife Fund (WWF) categorization system. This ecoregion borders Canada's taiga and contains a mix of subarctic forest and temperate forest species as a result. This makes the region an ecotone region, or a region that acts as a buffer between two other biomes.
The Yukon Interior dry forests is a taiga ecoregion of Canada.
The South Central Rockies forests is a temperate coniferous forest ecoregion of the United States located mainly in Wyoming, Idaho, and Montana. It has a considerably drier climate than the North Central Rockies forest.
The North Central Rockies forests is a temperate coniferous forest ecoregion of Canada and the United States. This region overlaps in large part with the North American inland temperate rainforest and gets more rain on average than the South Central Rockies forests and is notable for containing the only inland populations of many species from the Pacific coast.
Central Europe contains several life zones, depending on location and elevation.
A snowbank fungus is any one of a number of diverse species of fungi that occur adjacent to or within melting snow. They are most commonly found in the mountains of western North America where a deep snowpack accumulates during the winter and slowly melts through the spring and summer, often shaded by coniferous forest. They may be saprotrophic, mycorrhizal, or in the case of Caloscypha fulgens, pathogenic.
Waterton Biosphere Region is a UNESCO Biosphere Reserve encompassing Waterton Lakes National Park in the extreme southwest of the Province of Alberta, Canada. The region includes a section of the east slopes of the Rocky Mountains extending from the Continental Divide to the edge of the Canadian Great Plains to the east, including the Municipality of Pincher Creek and Cardston County. The Glacier Biosphere Reserve and National Park in Montana, USA is located to the south of the area.
The Alps conifer and mixed forests is a temperate coniferous forest ecoregion in central Europe. It extends along the Alps mountains through portions of France, Italy, Switzerland, Germany, Liechtenstein, Austria, and Slovenia. The ecoregion extends from the lower slopes of the Alps to its peaks, which include Mont Blanc, at 4,809 m (15,778 ft) the highest peak in the Alps.
