Endangered Amphibians

Conservation biologists tend to think of amphibians as environmental "canaries in the coal mine." When an ecosystem begins to tip out of balance, amphibians are generally the first to be affected. When frogs and salamanders begin to die en masse, it means that widescale ecological devastation may be under way.

More amphibian species are under threat than any single animal group, a wopping 1,811 species according to the IUCN. This accounts for around 31 percent of all known amphibians. Habitat loss and pollution appear to be the major causes.
