Abstract: Aim at the contradictory views on the invasiveness of Laguncularia racemosa, the introduced exotic mangrove species in China, in both the researchers and the administrators of mangrove wetlands, the primary survey on the distribution of Laguncularia racemosa in Hainan island was carried out, and the issue based on the related literature was explored. Plants of Laguncularia racemosa grow very well and have high fecundity on the coastal wetlands in Hainan and south China, and some of the individuals have invaded in Hainan native mangrove communities. It has the potential risk of biological invasion. Some important points on research were proposed: The mechanism of competition between Laguncularia racemosa and native mangrove species and the effects of Laguncularia racemosa on the native mangrove communities and its succession trend; the mechanisms of Laguncularia racemosa propagule disposal in natural way; The mechanisms of genetic differentiation of Laguncularia racemosa population and the environmental adaptation, in that to enhance understanding of the potential invasiveness and its potential threat on the biodiversity of native mangrove species.

Key words: exotic species, mangrove tree, Laguncularia racemosa C. F. Gaertn., invasiveness
