Mangrove Species Diversity of Sandwip Island of Chittagong, Bangladesh

The present study deals with the diversity of mangrove plant species of Sandwip Island of Chittagong, Bangladesh. A total of 18 mangrove plant species under 15 genera and 12 families have been documented from the study area. The species diversity has been investigated by random quadrat method. Shannon-Wiener diversity index (H`), species richness (d) and Pielou’s evenness index (J`) have been analysed by using PRIMER v6 program. Highly dominant species of the area are Excoecaria agallocha L., Zoysia matrella (L.) Merr., Sonneratia apetala Buch.-Ham. and Tamarix indica Willd. It can be concluded that the present study will be helpful for the planners and policy makers to plan for the better conservation and sustainable management of mangrove plant resources of Sandwip Island as well as to prepare a useful green belt to protect the coastal area..
