About this dataset

WWF global terrestrial ecoregion boundaries classifying the world's land into 867 distinct biogeographic units.

WWF Terrestrial Ecoregions (2017 update) divides the world's land into 867 ecoregions, grouped into 14 biomes and 8 biogeographic realms. Ecoregions are defined as relatively large units of land containing distinct natural communities that share species, dynamics, and environmental conditions. This is the standard framework for global biodiversity conservation planning.
