The following is a list of ecoregions in Canada as identified by the World Wide Fund for Nature (WWF).
The following is a list of ecoregions in Canada as identified by the World Wide Fund for Nature (WWF).
The terrestrial ecoregions of Canada are all within the Nearctic realm, which includes most of North America. The Nearctic, together with Eurasia's Palearctic realm, constitutes the Holarctic realm of the Northern Hemisphere. [1]
British Columbia is the most biodiverse province with 18 ecoregions across 4 biomes. By contrast, Prince Edward Island is the least biodiverse with just one ecoregion - the Gulf of St. Lawrence lowland forests - encompassing the entire province.
Canada is unique among countries in that it borders three marine realms: the Arctic, Temperate Northern Atlantic, and Temperate Northern Pacific. These realms can be further subdivided into three marine biomes and fifteen marine ecoregions based upon biological distinctiveness. [2]
Quebec is the only province that borders both the Arctic and Temperate Northern Atlantic realms.
A biome is a large collection of flora and fauna occupying a major habitat.
An ecoregion or ecozone is an ecologically and geographically defined area that is smaller than a bioregion, which in turn is smaller than a biogeographic realm. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation.
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface.
A biogeographic realm or ecozone is the broadest biogeographic division of Earth's land surface, based on distributional patterns of terrestrial organisms. They are subdivided into bioregions, which are further subdivided into ecoregions.
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa.
The Global 200 is the list of ecoregions identified by WWF, the global conservation organization, as priorities for conservation. According to WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species dynamics, and environmental conditions". So, for example, based on their levels of endemism, Madagascar gets multiple listings, ancient Lake Baikal gets one, and the North American Great Lakes get none.
A bioregion is an ecologically and geographically defined area that is smaller than a biogeographical realm, but larger than an ecoregion or an ecosystem, in the World Wide Fund for Nature classification scheme. There is also an attempt to use the term in a rank-less generalist sense, similar to the terms "biogeographic area" or "biogeographic unit".
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics.
The Arctic realm is one of the planet's twelve marine realms, as designated by the WWF and Nature Conservancy. It includes the coastal regions and continental shelves of the Arctic Ocean and adjacent seas, including the Arctic Archipelago, Hudson Bay, and the Labrador Sea of northern Canada, the seas surrounding Greenland, the northern and eastern coasts of Iceland, and the eastern Bering Sea.
Poland is part of four terrestrial ecoregions, one freshwater ecoregion, and one marine ecoregion.
The Southern Hudson Bay taiga is a terrestrial ecoregion, as classified by the World Wildlife Fund, which extends along the southern coast of Hudson Bay and resides within the larger taiga biome. Entirely located in Canada, it covers an area of approximately 373,735 km2 and crosses the provinces of Manitoba, Ontario, and the western portion of Quebec. Various islands in James Bay which belong to the Northwest Territories are also considered to be part of the ecoregion.
