WWF evaluated ecoregions of the world and identified the Global 200 as the most biologically distinct and, in conservation terms, the most valuable terrestrial, freshwater, and marine ecoregions on the planet.  Within these top-priority Global 200 ecoregions, WWF pursues ecoregion conservation, a unique, broad-scale approach that conserves species, habitats, and ecological processes. 

Four globally important “Global 200 Ecoregions” were identified in this area: “East Siberian taiga” “Mixed Broadleaf-Coniferous Forests of the Russian Far East,”(also known as Ussuri broadleaf and mixed forests ), “Dauria Steppe” and the all-encompassing freshwater ecoregion “Rivers and Wetlands of the Russian Far East” (commonly called “Amur Basin freshwater" or Global 200 Amur Wetlands ecoregion).
