Abstract

The coastal belt of Purba Medinipur District is about 68 km starting from the Mohana of Rasulpur River at Hijli Sarif of Khejuri extended upto the udoypur beach of Digha Border. The total coastal belt is divided into 10 sections (Hijli Sarif, Petuaghat, Bankiput, Junput, Haripur, Shoula, Mandarmoni, Tajpur, Sankarpur and Digha) for the accuracy of investigation. The present comprehensive study on the mangrove vegetation reported nine mangrove species under seven genera and five families from the ten coastal sections. The dominating mangrove taxa are Avicennia, Bruguiera, Ceriops, Excoecaria and Sonneratia. The mangrove species are found to occur in high frequency in Hijli Sarif, Petuaghat, Bankiput, Sankarpur and Digha Mohana. The phytosociological association of the mangrove has also been studied. The richness of mangrove vegetation on the coastal belt of Purba Medinipur district is greatly hampered due to dry fish industries as well as continuous ferry activities of fisherman and daily uses of mangroves as fuels by local people. In the light of present scenario immediate steps to be taken for their sustenance.
