"There are signs of hope for American salamanders in the face of a potential biological catastrophe — a fungus that could be carried here through the global trade in exotic pets. Federal wildlife officials have signaled a crackdown may be coming on imports of amphibians.

Here’s the sequence of events.

Last year, biologists identified a virulent imported fungus, Batrachochytrium salamandrivorans, as the cause of a steep drop in salamander populations in continental Europe. Herpetologists quickly began pressing United States agencies and officials to clamp down on the global exotic pet trade to cut the chances of the disease reaching the United States — which has the most diverse salamander population in the world."
