Once Extinct in the Wild, Kihansi Spray Toad Returns to Tanzania (by Way of the Bronx and Toledo) by +John Platt at +Scientific American. Just the sort of story that highlights the critical role of zoos and aquariums in conservation.

Two American zoos have helped to save an African amphibian from extinction. The Kihansi spray toad (Nectophrynoides asperginis) was declared extinct in the wild in 2009 after its only habitat, the waterfalls of Kihansi Gorge in Tanzania, dried up following the establishment of a nearby hydroelectric dam. But this month 2,000 toads returned to Kihansi, courtesy of scientists at the Wildlife Conservation Society’s (WCS) Bronx Zoo and at the Toledo Zoo. The achievement marks the first time that an extinct-in-the-wild amphibian has been returned to its native habitat.
