Ecoregions and priority regions

Areas of high biodiversity value

Ecoregions of the Greater Mekong

There are very few geographic areas on the globe which have so many Global 200 priority ecoregions in such close proximity.

A lot of our work is done here...

The WWF Greater Mekong Programme currently focuses on 3 ecoregions:

In these ecoregions WWF has developed Ecoregion Action Plans (EAP).

...but we also work in these areas

Other important ecoregions where the WWF Greater Mekong Programme works include:

The WWF Greater Mekong Programme considers all of these regions a priority. However, planning and implementation are at different stages.

What is an ecoregion?

Biodiversity is not spread evenly across the Earth but follows complex patterns determined by climate, geology and the evolutionary history of the planet. These patterns are called ecoregions. WWF defines an ecoregion as a large unit of land or water containing a geographically distinct assemblage of species, natural communities, and environmental conditions.
