Seven primate species are reported at Nankang, a site of about 34 km2 between Nature Reserves of Xiaoheishan and Gaoligongshan. That so many primate species occur in such a small area is the only case known in China. The site is managed as a habitat corridor (NC) by the reserves. This project is designed to:

(1) check the richness and population of primates;

(2) specify the threats to the primate community.

This is a pioneer work for site-specific conservation efforts, and for further studies on the little known species in the world and their community.
