A tiny fraction of our planet’s water—less than one hundredth of one percent—exists as liquid freshwater. But the biodiversity this fraction houses is astonishing. For example, did you know that the southeastern United States is home to more freshwater species than anywhere else in the world?

Despite their richness and importance, freshwater ecosystems have often received scant attention, even from the conservation community. Learn more about protecting threatened freshwater ecosystems and the species they support from Larry Master, NatureServe’s former chief scientist and lead author of the seminal report Rivers of Life, and Jay Cordeiro, consulting zoologist for NatureServe.
