OMAHA, Neb. -- The global amphibian crisis continues to grow as conservationists estimate that up to half of all species of amphibians will go extinct in the next five to 10 years. Dr. Lee Simmons said Omaha's Henry Doorly Zoo is taking the lead on a global scale to help save the world's amphibians. Inside a quarantined area at the zoo, conservation effort is under way.
Trace Hardin, a reptile and amphibian keeper at the zoo, along with Simmons, said habitat loss, disease and pollution threaten the world's amphibian population. Together with chitryd fungus, the circumstances are combing to make the amphibian population disappear at what the researchers called an alarming rate. Of the 6,000 known species, experts believe up to 3,000 will disappear within the next decade.
Simmons said the chitryd fungus has been disastrous. He said it was spread around the globe by the African clod frog. Humans shipped the frogs to different countries for pregnancy tests. The African clod frog is unaffected by the chitryd fungus, but the fungus kills most other amphibians. "If you take that big of a biomass out of the environment, the ripple effect has to be horrendous," Simmons said.
Henry Doorly's amphibian conservation area will hold up to 50 species of amphibians. Each room is a biologically isolated room with fresh air, it's own heating and air conditioning system, Simmon said. Omaha's zoo, along with others, are trying to save whatever amphibian species they can. They gather populations near extinction, put them in captivity, breed them and then try to reintroduce them to their habitat. A remnant population of the species are kept in captivity as a safety net.
