Abstract: Natural resources of dove trees (Davidia involucrata Bali) are rich in Guizhou province, China. Especially in Fanjingshan Mountain Reservation, there is a primeval forest community of dove trees distributed over the area of Heizhan, from 1,000 to 1,800 metres above sea level. In this paper the authors point out that the species composition of the dove tree forest is compartively complex,and mixed by both deciduous and evergreen trees. The importances of dove trees in ecology and resource conservation are discussed as well.
