Amphibians are cold-blooded vertebrates that are most similar to fishes and reptiles. Like fishes, amphibians can live in the water. Like reptiles, many amphibians can also live on land. In fact, amphibians were the first vertebrate to move from a water habitat to a terrestrial one.
Chiricahua leopard frog
Columbia spotted frog
Oregon spotted frog
Sonora tiger salamander
are among the most imperiled species on earth. Scientific
research is providing mounting evidence that amphibians are in trouble.
Ubiquitous toxins, global warming, ozone depletion, the introduction of
nonnative fish, and habitat destruction are key factors leading to the demise.
However, amphibian declines are also present in some of our largest National
parks and wilderness areas. Up to one-third of 230 native species in the
United States are declining in numbers. Frog deformities have been reported
in 42 states. Most disturbing, according to the U.S. Department of Interior,
is that the population declines are "global, sudden, and precipitous."
Amphibians are good
"indicators" of significant environmental
The Center is working
to halt this trend. Since our inception over ten years ago we have been
working to protect amphibian populations across the southwest, and more
recently across the west. Our amphibian program includes the following:
