River Chandragiri is the longest river of Kasaragod district, Kerala. One of the characteristic features of this river is the presence of six deltas formed by deposition. These are having a history of several hundred years. An inventory on the floristic diversity of these deltas was carried out from January 2019 to December 2020 with the aim of elucidating their role in conservation of endemic and rare plants of Western Ghats. The vegetation is of moist mixed deciduous type. The flora of these deltas show variation from that of rest of Kasaragod as these have a number of plants which are sown there by the flood water from the Ghats. Present study enumerated 48 endemic angiosperms belonging to 43 genera and 30 families. These deltas also accounted for 33 species which qualify for different IUCN red list categories. Of these, 14 are vulnerable, 5 rare, 4 endangered, 4 low risk, 2 critically endangered, 3 near threatened and one data deficient species. These results are the clear indicators of their pilot role in conserving the rare as well as endemic plants of the Western Ghats. Due to increasing anthropogenic activities the natural flora of these deltas are now gradually disappearing, making the way for weeds and cultivated plants. Hence there is an urgent need for conservation.
