Saving the world’s most endangered freshwater species by eradicating invasive animals
FRESHWATERS ARE IMPORTANT:
Freshwaters make up less than 1% of Earth, but are home to 10% of earth’s species and a third of all vertebrate species.
Freshwaters have about the same number of fish species as the world’s oceans, which are more than 70 times larger.
Freshwaters provide half of all wild food fish and are particularly important for the world’s poorest people.
Freshwaters are threatened
Freshwaters make up less than 1% of earth, but are home to 28% of Extinct species, like those pictured here, and 29% of Critically Endangered species.
Invasive species like these carp are responsible, at least in part, for 41% of all freshwater extinctions. But, they can be eradicated, after which, even species on the edge of extinction can make spectacular recoveries.
The Endangered White-headed duck recovered in Laguna de Zóñar, Spain after invasive carp were eradicated. Numbers of 5 other water birds, including flamingos, also increased.

Invasive eradications can also benefit water quality for people and wildlife.
There are thousands of opportunities, like Laguna de Zóñar, to save threatened species from extinction and benefit people by eradicating invasive species.
