Abstract: To provide a scientific basis for the conservation and exploitation of wild Cerasus species in Dawei Mountain, we investigated the community characteristics and species diversity of Cerasus species. The results showed that there were four Cerasus communities, C. campanulata, C. diel-siana, C. conradinae and C. xueluoensis, in Dawei Mountain. Phaenerophyte in the life form and pantropical elements in the local flora were both dominant. The shrub layer had higher species diversity than that of the arbor layer. Species diversity of those four communities was following the order of C. dielsiana, C. conradinae, C. campanulata and C. xueluoensis. The community structure was relatively stable when young and mature individuals of Cerasus predominated. The ground dia-meter class structure indicated that the C. xueluoensis population was a growing population with a typical pyramid structure. The C. conradinae community was mono-dominated by C. conradinae, with C. dielsiana and C. campanulata as the important companion species. Those three Cerasus species would be replaced by other coniferous and broadleaved species due to the shortage of natural regeneration.
