Can We Save These Rare Toads From Extinction? (4:48)
Partners: University of Wyoming, Cheyenne Mountain Zoo, Saratoga National Fish Hatchery, and many others
Produced by: National Geographic


At one time there was only one known Wyoming toad in the wild. Once a frequent sight on the Wyoming plains, the toad had nearly become extinct after a sharp decrease in population in the late 1970s. Habitat loss, climate change, and a fungus are all factors in its decline. The species was listed as endangered in 1984, and declared extinct in the wild not long after. But efforts to raise the animals in captivity have been successful, and a recent survey found 200 toads. It's a positive sign that the toads can sustain themselves in the wilds of Wyoming.
