Solutions for Rivers: Ecoregions
Natural boundaries to life
The 50 rivers WWF concentrates its work on, all fall, partly or entirely, within priority ecoregions.
EcoregionsLife does not recognise man made boundaries. Instead, it is limited by the boundaries set by climate - rainfall and temperature - and those set by physical geography - land, sea, lake and river conditions.
These natural boundaries to life define what we call "ecoregions” (literally an ecological region). Places where types of animals and plants are grouped together, living within the boundaries set by natural conditions.
Of all the those that currently exist, WWF has defined 238 ecoregions that should be a priority for conservation action. Places on this planet where, if we focus our work, we stand the best chance of conserving the diversity of life on Earth.
Together, these 238 ecoregions provide a critical blueprint for global conservation action. WWF calls these critical ecoregions the Global 200.
