A LEAST CONCERN MANGROVE SPECIES SONNERATIA CASEOLARIS REPORTED FROM POOVAR ESTUARY, THIRUVANANTHAPURAM, KERALA

Premjith S, Praveen P

Abstract


Mangrove species are uniquely adapted to tropical and subtropical coasts. Mangrove areas are highly threatened due to susceptibility to climate change, sea level rise and increasing pressures from human population growth in coastal regions. Mangrove ecosystem of Poovar is declining rapidly as they are cleared for coastal development and logged for timber and fuel production. In Poovar more than half of the mangrove area is under private ownership which makes conservation difficult. Little is known about the effects of mangrove area loss on individual mangrove species and local or regional populations. Each species' probability of extinction shall be assessed under the categories and criteria of the IUCN Red list of threatened species. Many mangrove species of Poovar estuary are at elevated threat of extinction.  A very few Sonneratia caseolaris, a threatened and least concern as per IUCN list mangrove species are reported from estuarine region of the Poovar coast. Immediate and effective conservation measures should be taken for their protection and propagation for recovery.
