As an endemic specie to Hainan, Dalbergia odorifera T. Chen belongs to the second national-class important wild conservative plant, which not only used as a superior material timber for high-grade furniture and elegant handicraft, but also as a famous traditional Chinese medicine. We investigated wild population in Hainan island that showed there were 43 families of vascular plants including 68 genera and 71 species in Dalbergia odorifera wild community without obvious dominant family. The proportion of single-species families and the monotypic genera was high. The geographic element of the community flora was multiple, and predominant with tropical element. The wild community was distributed in two different habitats: the Limestone habitat and the Granite habitat. Dalbergia odorifera was adaptable to soil fertility and pH value. Excessive logging and habitat loss became main factors for this species to be seriously damaged. According to IUCN criterion, it is regarded as to be CE (critically endangered) species. Therefore, scientific conservation strategy is put forward in this paper and acclimatization theory is provided which not only help to guide market demand but also support the sustainable utilization.
