With the total area of 381 hectares, the Vatica mangachapoi forest in Sanfenqu of Jianfengling National Nature Reserve is one of the best protected forests over the whole Hainan Island. Based on the sample plots data (total plots area is 1.38 hectares), there are more than 300 tree species recorded and the mean timber volume is 469.773 m~3·hm~-2, the mean diameter at breast height (DBH) of all trees is 28.6 cm and the maximum DBH is 143.3 cm; V. mangachapoi (Dipterocarpaceae) is the dominant and key stone species in the forest ecosystem, and the population density (DBH 12 cm) is 48 individuals per hectare and the population important value (Ⅳ) is 16.8 (the total Ⅳ of all populations is 300). The population age structure of V. mangachapoi now presents as steady increasing population, the tree number is gradually decreasing with the tree DBH increasing. Based on the results of cluster analyse, the V. mangachapoi forest belongs to the tropical monsoon forest and mainly distributes between 300 to 650 m above sea level. The sub-dominant species of V. mangachapoi forest are Koilodepas hainanensis, Amesiodendron chinensis and Litchi chinensis var. euspontanea. 8 national key protected species are recorded in Sanfenqu, Hopea hainanensis (Dipterocarpaceae) is the first grade of the national key protected species.
