Bioregions became a foundational concept within the philosophical system called Bioregionalism.A key difference between an ecoregions and biogeography and the term bioregion, is that while ecoregions are based on general biophysical and ecosystem data, human settlement and cultural patterns play a key role for how a bioregion is defined.
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. Each ecoregion is classified into one of 14 major habitat types, or biomes.

Bioregional mapping is a participatory approach to cartography that focuses on mapping the natural, ecological, and cultural features of a bioregion—an area defined by its natural boundaries, such as watersheds, ecosystems, and cultures that arise form a place, rather than human borders. [1]
