On the basis of historical data, the ancient trees in 6 towns around Xinfengjiang reservoir were measured and located by the combined methods of field investigation and interview. The results indicated that there are 59 ancient trees that belong to 13 species, such as Altingia tenuifolia, Schima superba, Bischofia javanica, Ficus microcarpa and so on, that belong 12 genera of 10 families in 6 towns around Xinfengjiang reservoir. The structure of ancient trees resource showed that the tree age was concentrated in the range of 200 to 300 years, with 49, 8 and 2 individuals for age class Ⅲ, Ⅱ and Ⅰ, respectively. Tree height was mainly concentrated in 17.0~25.0 m with average height of 22.9 m. The diameter at breast height(DBH) was mainly concentrated in 50.0~125.0 cm with average DBH of 118.0 m. The crown width was mainly concentrated in 10.0~17.0 m with average crown width of 17.1 m. Most ancient trees were located in Xingang town, on the southeast of Xinfengjiang reservoir. All ancient trees around Xinfengjiang reservoir are protected as Feng-Shui woods and the overall growth condition is good. There are 46, 11 and 2 strains of normal, weak and endangered trees, respectively. The poor growing environment, lacking management and protection, as well as disease and insect pests are the primary cause for ancient trees growing weakly and dying. Some suggestions on management and protection of ancient trees around Xinfengjiang reservoir are proposed on the basis of investigation results.
