Pacific Maritime Ecozone (CEC)
The Pacific Maritime Ecozone, as defined by the Commission for Environmental Cooperation (CEC), is a Canadian terrestrial ecozone, spanning a strip approximately 200 kilometres wide along the British Columbia Coast, then narrowing along the border with Alaska. It also includes all marine islands of British Columbia and a small portion of the southwestern corner of the Yukon. Fourteen ecoregions comprise the Ecozone, ranging from the Mount Logan Ecoregion in the north to the Cascade Ecoregion and Lower Mainland Ecoregion in the south. The name of the comparable ecozones in the United States, where Level II ecoregions correspond to the international term "ecozone", are the Marine West Coast Forest and the Northwestern Forested Mountains ecoregions. In the floristic province system, the region is described as part of the Rocky Mountain Floristic Region. Also in use is a system of biogeoclimatic zones defined and used by the British Columbia government, which defines th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific Temperate Rainforests
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 Pacific tempe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Ecoregions In The United States (EPA)
This list of ecoregions in the United States provides an overview of United States ecoregions designated by the U.S. Environmental Protection Agency (EPA) and the Commission for Environmental Cooperation (CEC). The CEC was established in 1994 by the member states of Canada, Mexico, and the United States to address regional environmental concerns under the North American Agreement on Environmental Cooperation (NAAEC), the environmental side accord to the North American Free Trade Agreement (NAFTA). The Commission's 1997 report, ''Ecological Regions of North America'', provides a framework that may be used by government agencies, non-governmental organizations, and academic researchers as a basis for risk analysis, resource management, and environmental study of the continent's ecosystems. In the United States, the EPA and the United States Geological Survey (USGS) are the principal federal agencies working with the CEC to define and map ecoregions. Ecoregions may be identified ...

Alpine Tundra
Alpine tundra is a type of natural region or biome that does not contain trees because it is at high elevation, with an associated alpine climate, harsh climate. As the latitude of a location approaches the poles, the threshold elevation for alpine tundra gets lower until it reaches sea level, and alpine tundra merges with tundra#Arctic tundra, polar tundra. The high elevation causes an adverse climate, which is too cold and windy to support tree growth. Alpine tundra ecotone, transitions to sub-alpine forests below the tree line; stunted forests occurring at the forest-tundra ecotone are known as ''Krummholz''. With increasing elevation it ends at the snow line where snow and ice persist through summer. Alpine tundra occurs in mountains worldwide. The flora of the alpine tundra is characterized by dwarf shrubs close to the ground. The cold climate of the alpine tundra is caused by adiabatic cooling of air, and is similar to polar climate. Geography Alpine tundra occurs at hi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

British Columbia Mainland Coastal Forests
British Columbia mainland coastal forests is a temperate coniferous forest ecoregion the Pacific coast of North America, as defined by the World Wildlife Fund (WWF) categorization system. Setting The WWF defines the ecoregion as the mainland coast of British Columbia up to 150 km inland to the crest of the Coast Mountains, extending along the western front of the northern Cascade Range in northwestern Washington. Specific areas include the Pacific and Kitimat Ranges of the Coast Mountains, the Nass Ranges and the basin of the Nass River. An exclave of the ecoregion occupies the eastern slope of the Olympic Mountains on Washington's Olympic Peninsula. The landscape is a mixture of coastal lowland with many steep valleys, inlets, and fjords. The climate is drier on the inland mountains than right on the coast and the average annual temperature in the valleys is 6.5 °C. Major urban centres located within this ecoregion include Whistler, Terrace, Kitimat, and Prince Ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vancouver Island
Vancouver Island is an island in the northeastern Pacific Ocean and part of the Canadian Provinces and territories of Canada, province of British Columbia. The island is in length, in width at its widest point, and in total area, while are of land. The island is the largest by area and the most populous along the west coasts of the Americas. The southern part of Vancouver Island and some of the nearby Gulf Islands are the only parts of British Columbia or Western Canada to lie south of the 49th parallel north, 49th parallel.
