Join former Collections Manager Bian Tan on an expedition to the highlands of northern Vietnam (February 2001). In the ongoing effort to develop San Francisco Botanical Garden's Southeast Asian Cloud Forest, Bian joined researchers from the Missouri Botanical Gardens, the Institute of Ecology and Bioresources in Hanoi, and the Russian Academy of Sciences in St. Petersburg. The variety of plants encountered was amazing, and included many rare conifers and orchids. Follow Bian into limestone areas that are home to rare and endangered species, where scientists are racing against time to document biodiversity before it is destroyed and becomes extinct.
