Collaboration is the key to conservation in countries like Vietnam, where the known frog diversity has doubled since 1999. Struggling to keep pace with the growing threats to the country's biodiversity, especially its more than 150 amphibian species, AMNH researchers Darrel Frost and Chris Raxworthy and Raoul Bain of the Center for Biodiversity and Conservation explore remote regions to document specialized frog populations. They also teach survey and collection techniques to local herpetologists. Each study reveals more biological treasures, including eight frog species discovered in 2003.
