A recent study revealed amphibian declines are occurring much more rapidly and more widespread than expected in species populations across the United States, even in protected national parks and wildlife refuges."This new study confirms that our country's amphibians are facing an extinction crisis that demands aggressive action to tackle threats like habitat destruction and climate change," said Collette Adkins Giese, a Center for Biological Diversity biologist and attorney focusing on protection of amphibians and reptiles. "Scientists have known for a long time that frogs, toads and salamanders are in big trouble, but the declines this study documents are surprising and disturbing."
