This page features a list of biogeographic provinces that were developed by Miklos Udvardy in 1975, [1] [2] later modified by other authors. [according to whom?] Biogeographic Province is a biotic subdivision of biogeographic realms subdivided into ecoregions, which are classified based on their biomes or habitat types and, on this page, correspond to the floristic kingdoms of botany.
Biogeographic realms are characterized by the evolutionary history of the organisms they contain. They are distinct from biomes , also known as major habitat types, which are divisions of the Earth's surface based on life form , or the adaptation of animals, fungi, micro-organisms and plants to climatic, soil , and other conditions.
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.
Biogeographic realm or Ecozone is a classification system of the world first proposed by Miklos Udvardy for conservation purposes.
The WWF uses three main classifications: Biogeographic realms (also called ecozones), biomes (also called major habitat types), and ecoregions. [ 1 ] [ 2 ] Global 200 ecoregions (WWF), 238 single or combined ecoregions identified by the World Wildlife Fund (WWF) as priorities for conservation.

Argentina's largest province, if these claims are included. New Kingdom of Egypt: 1,000,000: The final imperial phase of dynastic Egypt, lasting from 1570–1070 BC. Khmer Empire: 1,000,000: Hindu/Buddhist empire in Southeast Asia. Oceanian realm: 1,000,000: One of the eight biogeographic realms of the Earth. West Siberian economic region: 992,000
One of the most comprehensive early classifications was the system of 53 coastal provinces developed by Briggs in 1974. [3] The near-global system of 64 large marine ecosystems has a partial biogeographic basis. WWF Global 200. The World Wildlife Fund—WWF identified 43 priority marine ecoregions, as part of its Global 200 initiative. [4]
