Global 200

The Global 200 is the list of ecoregions identified by the World Wildlife Fund (WWF) as priorities for conservation.

•  According to the WWF, an ecoregion is defined as a "relatively large unit of land or water containing a characteristic set of natural communities that share a large majority of their species, dynamics, and environmental conditions (Dinerstein et al. 1995, TNC 1997)."

The WWF assigns a conservation status to each ecoregion in the Global 200: critical or endangered; vulnerable; and relatively stable or intact.

• Over half of the ecoregions in the Global 200 are rated endangered.
