Life table analysis and spectral analysis of Phellodendron amurense population, an endangered-medicinal plant, in the Yunmengshan Park

Abstract
Phellodendron amurense is an endangered-medicinal tree species and its conservation is urgent. Study on population structure and dynamics is essential for its conservation. Life table analysis and spectrum analysis were used to analyze population characteristics and dynamics in the Yunmengshan National Forest Park (YMNFP), Beijing, China. Results showed that the size and density of amur cork population in YMNFP was low. It 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. A nature reserve for P. amurense population should be suggested in YMNFP.
