World Wildlife Fund
The World Wide Fund for Nature Inc. (WWF) is an international non-governmental organization founded in 1961 that works in the field of wilderness preservation and the reduction of human impact on the environment. It was formerly named the World Wildlife Fund, which remains its official name in Canada and the United States. WWF is the world's largest conservation organization, with over five million supporters worldwide, working in more than 100 countries and supporting around 3,000 conservation and environmental projects. They have invested over $1 billion in more than 12,000 conservation initiatives since 1995. WWF is a foundation with 65% of funding from individuals and bequests, 17% from government sources (such as the World Bank, DFID, and USAID) and 8% from corporations in 2020. WWF aims to "stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature." The Living Planet Report has been published every two ...

Terrestrial Ecoregion
An ecoregion (ecological region) or ecozone (ecological zone) 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 (largely undefined at this point). Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic framework is optimal for all taxa. Ecoregions reflect the best compromise for as many taxa as possible. Se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Ecoregion
A marine ecoregion is an ecoregion, or ecological region, of the oceans and seas identified and defined based on biogeographic characteristics. Introduction A more complete definition describes them as “Areas of relatively homogeneous species composition, clearly distinct from adjacent systems” dominated by “a small number of ecosystems and/or a distinct suite of oceanographic or topographic features”. Ecologically they “are strongly cohesive units, sufficiently large to encompass ecological or life history processes for most sedentary species.”Spalding, Mark D., Helen E. Fox, Gerald R.

Global 200
The Global 200 is the list of ecoregions identified by the World Wide Fund for Nature ( 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". 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. The WWF assigns a conservation status to each ecoregion in the Global 200: critical or endangered; vulnerable; and relatively stable or intact. Over half of the ecoregions in the Global 200 are rated endangered. Background The WWF has identified 867 terrestrial ecoregions across the Earth's land surface, as well as freshwater and marine ecoregions. The goal of this classification system is to ensure that the full range of ecosystems wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Terrestrial Ecoregions (WWF)
This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial, freshwater, and marine ecoregions. The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms, containing 867 smaller ecoregions. Each ecoregion is classified into one of 14 major habitat types, or biomes. In 2017 the WWF team revised ecosystem names and boundaries in the Arabian Peninsula, drier African regions, and Southeastern United States.Eric Dinerstein, David Olson, et al. (2017). An Ecoregion-Based Approach to Protecting Half the Terrestrial Realm, BioScience, Volume 67, Issue 6, June 2017, Pages 534–545, Additional ecoregions for Antarctic Realm are currently being incorporated (based on Terauds et al. 2012).

List Of Marine Ecoregions (WWF)
The following is a list of marine ecoregions, as defined by the WWF and The Nature Conservancy The WWF/Nature Conservancy scheme groups the individual ecoregions into 12 marine realms, which represent the broad latitudinal divisions of polar, temperate, and tropical seas, with subdivisions based on ocean basins. The marine realms are subdivided into 62 marine provinces, which include one or more of the 232 marine ecoregions. The WWF/Nature Conservancy scheme currently encompasses only coastal and continental shelf areas. Arctic realm (no provinces identified) *North Greenland * North and East Iceland * East Greenland Shelf * West Greenland Shelf * Northern Grand Banks-Southern Labrador * Northern Labrador * Baffin Bay-Davis Strait * Hudson Complex *Lancaster Sound *High Arctic Archipelago * Beaufort-Admunsen-Viscount Melville-Queen Maud * Beaufort Sea-continental coast and shelf *Chukchi Sea *Eastern Bering Sea *East Siberian Sea *Laptev Sea *Kara Sea *North and East Barents ...

List Of Freshwater Ecoregions (WWF)
This is a list of freshwater ecoregions as compiled by the World Wildlife Fund (WWF). The freshwater ecoregion system is similar to that for terrestrial ecoregions. The Earth's land surface is divided into eight terrestrial biogeographic realms or ecozones, which contain hundreds of smaller ecoregions. Ecoregions are classified into biomes or major habitat types, which have similar climates and vegetation types. The freshwater system is similar, with ecoregions classified into freshwater realms and biomes. Afrotropical Ecoregions are sorted by biome (major habitat type). The numbers are WWF's ecoregion codes. Large lakes *559; Lake Malawi; (Malawi, Mozambique, Tanzania) *565; Lake Rukwa; (Tanzania) *542; Lake Tanganyika; (Burundi, Democratic Republic of the Congo, Rwanda, Tanzania, Zambia) *530; Lake Turkana; (Kenya) *521; Lake Victoria Basin; (Burundi, Democratic Republic of the Congo, Kenya, Tanzania, Uganda) Large river deltas *506; Niger Delta; Montane freshwaters *541; ...
