Abstract: The study focuses on assessing the floristic and structural analysis ofthe mangrove species of Kadalundi-Vallikunnu Community Reserve, Kerala, India. Phytosociological analysis was conducted in 25 sites using quadrate method (species area curve method). To determine the floristic and structural composition, standard formulas of density, abundance, % frequency, basal area, important value index (IVI), and their relative values was used. Community structure was interpreted using the diversity indices viz. Shannon Weiner index, equitability, and Simpson?s Index functions. A total of seven species of mangrove which belonged to 6 genera and 5 families were recorded from the study area. Avicennia officinalis was the dominant one in terms of number followed by Acanthus ilicifolius and R. mucronata. Shannon index value (H') of 5.27 and Species richness (d) of 0.778 were also recorded. The Shannon index values of the sites indicated a highest Shannon index and Equitability of (H?5.27, 2.05). The present study indicates that anthropogenic activities like heavy sand mining, land filling for constructional purposes, waste dumping pose problems for mangrove biodiversity and its natural regeneration which may affect the biodiversity of the area.
