Lists of ecoregions

Wikipedia has articles relating to several ecoregion classification systems, defined by the conservation group World Wildlife Fund (WWF), the Commission for Environmental Cooperation (CEC), and like agencies around the world. The WWF uses three main classifications: Biogeographic realms (also called ecozones), biomes (also called major habitat types), and ecoregions.^[1][2]
