"Frog, Toad and Salamander Populations Plummeting, U.S. Survey Finds"

"Frogs, toads and salamanders continue to vanish from the American landscape at an alarming pace, with seven species — including Colorado’s boreal toad and Nevada’s yellow-legged frog — facing 50 percent drops in their numbers within seven years if the current rate of decline continues, according to new government research."



"The U.S. Geological Survey study, released Wednesday, is the first to document how quickly amphibians are disappearing, as well as how low the populations of the threatened species could go, given current trends.

The exact reasons for the decline in amphibians, first noticed decades ago, remain unclear. But scientists believe several factors, including disease, an explosion of invasive species, climate change and pesticide use are contributing."
