List of ecoregions (WWF)

This is a list of 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 terrestrial ecozones, containing 867 smaller ecoregions. Each ecoregion is classified into one of 14 major habitat types, or biomes.

Freshwater ecoregions and marine ecoregions are also classified by geographic region and by habitat type.

The WWF/Nature Conservancy scheme for marine ecoregions 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; ecoregions of the deep oceans have not yet been delineated.

Many consider this classification to be quite decisive, and some propose these as stable borders for bioregional democracy initiatives.

The WWF has also designated the Global 200, a list of priority ecoregions for conservation. Many of the Global 200's terrestrial, freshwater and marine ecoregions are composites of two or more individual ecoregions. For the list of Global 200 ecoregions, see Global 200.
