XTBG is one of the earliest institutions engaged in conservation biology research. Major research projects focus on the in situ and ex situ conservation of rare and endangered plant species, exploration and development of appropriate management, and the investigation of indigenous knowledge for conservation actions. Using physiological and molecular study, the natural patterns and dynamics of rare and endangered species in the tropical and subtropical forest ecosystems are discovered and the mechanisms of species extinction and endangerment are determined. Research groups include the following:
