Structural characteristics of mangrove forest in different coastal habitats of Gulf of Khambhat arid region of Gujarat, west coast of India
Tropical mangroves are most productive and highly sensitive to environmental change and act as good bio-indicators of the environmental quality and health of any coastal ecosystem. The present study initiated to know the current ecological status of mangrove species at four selected study sites name...

Tropical mangroves are most productive and highly sensitive to environmental change and act as good bio-indicators of the environmental quality and health of any coastal ecosystem. The present study initiated to know the current ecological status of mangrove species at four selected study sites namely Bhavnagar (Ghogha coast), Bharuch (Dahej coast), Surat (Dumas beach) and Navsari (Purna estuaries), Gulf of Khambhat, Gujarat, India. Observation for a period of one year from January 2014 to December 2014. Mangroves were evaluated for their community structures at each site by standard quadrant method and different diversity indices were used for characterize the species diversity in a mangrove community. The mangrove forest habitat supports the occurrence of a total 16 species (6 mangrove species and 10 associated plant species), 15 species occurred at Navsari, whereas 7, 6 and 10 species occurred at Bhavnagar, Bharuch and Surat respectively. Out of six mangrove species, Avicennia marina was found to be most dominant and abundant mangroves occurring among all the four study locations.
