In recent years, scientists from around the world have turned to Vietnam in their search for new plant and animal species. Vietnam harbors an astonishing range of habitats, from rain forests and dry forests to mangroves and coral reefs. Scientific expeditions and surveys have discovered an amazing range of biodiversity. But even as this biodiversity is being revealed, it is coming under threat from development and human activity. Scientists now are racing to accomplish their studies in an effort to keep Vietnam's biological wealth from disappearing entirely.
