A rapid biological assessment was conducted at three sites in the mountains of China's Sichuan Province in 2005. In the course of this project, a team of Chinese and international biodiversity experts surveyed the diversity of plants, birds, mammals, reptiles and amphibians, and insects in order to determine and justify boundaries for the expansion of nature reserves and parks in the region. The data collected here, including the most up-to-date information on new and threatened species, will be used by Conservation International and local Tibetan communities to demonstrate the rich biodiversity in their area and help promote protection of lands beyond their communities.
