Present research deals with the effects of deadly Amphan super cyclone on plant diversity in the East Midnapore coastal belt. Super tropical cyclone Amphan made landfall near Bakkhali in 24 Parganas in West Bengal and affected the total coastal area of West Bengal. East Midnapore district Ramnagar-I & II, Contai-I, Deshpran, Khejuri-II, Nandigram-I, Sutahata Block, and Haldia municipality are the affected areas. Khejuri –II and Nandigram-I block were damaged remarkably. In those two blocks, most old trees were broken, uprooted, or both. Significant loss of plant diversity was occurred by this severe super cyclone. Still, the most predicted point for the landfall of Amphan Digha under Ramnagar-I block was affected in minimum level. It was noted that throughout the Midnapore coastline, manmade vegetation was damaged maximum. Mainly Casuarina and Eucalyptus trees were affected very much. Trees were more damaged rather than shrubs and herbs. Mangrove plants just in front of the sea line were destroyed less than backside manmade terrestrial vegetation.
