World Wildlife Fund Terrestrial Ecoregions

Title: World Wildlife Fund Terrestrial Ecoregions

Abstract: World Wildlife Fund Terrestrial Ecoregions represents global terrestrial ecoregions. Ecoregions are defined as relatively large areas of land or water containing a characteristic set of natural communities that share a large majority of their species, dynamics, and environmental conditions. This dataset contains all terrestrial ecoregions, which include those of the Global 200 ecoregions, a collection of the earth's most outstanding and diverse terrestrial, freshwater, and marine habitats where the earth's biological wealth is most distinctive and rich, where its loss will be most severely felt, and which we must protect if we are to preserve the web of life.
