Abstract
Study on population structure and dynamics of Phellodendron amurense, an endangered-medicinal tree species, is essential and urgent for its conservation in China. The aim of this work is to study the characteristics and dynamic regulations of P. amurense population in the Yunmengshan National Forest Park (YMNFP), Beijing, China. A set of systemic sampling plots was established along an altitudinal gradient to collect population data. Life table analysis and spectrum analysis were used to analyze the data set. Results showed that the size and density of amur cork population in YMNFP was low. Its survival curve was between Deevey-I and Deevey-II with a reasonable and stable age structure. It had apparently periodic fluctuation controlled by population biological features. Effective conservation for this population must consider these characters. Population restoration should be treated as the main target of conservation, and disturbance intensity must be controlled effectively. A nature reserve for P. amurense population should be suggested and established in YMNFP
