Southeast Asia is a region of concern with mangrove deforestation rates between 3.58 percent and 8.08 percent during the analysis period, this in a region containing half of the entire global mangrove forest inventory. Globally, the IWP and the Atlantic, East Pacific (AEP) have different mangrove species groups (Hogarth, 2007; Spalding et al., 2010). Mangrove environment is highly dynamic and harsh and mangrove species are variously adapted to cope with these environmental conditions. plant species of which 39 are true mangroves and 86 are mangrove associates. Nursery Ground Some reef fish require mangrove forest to complete their life cycle: ¾Adult fish migrate to mangrove forest to spawn (lay eggs or larvae) ¾Juvenile fish depend of mangrove roots to serve as a refuge from large predators. The results showed that there are thirty (30) major and minor mangrove species; twenty-two (22) mangrove associates and ten (10) specialized groups identified.

Species of mangrove associates comprise 30 trees, 24 shrubs, 18 herbs, 6 climbers, 4 grasses and 4 epiphytes (Kathiresan et al., 2009). The Mangroves had been degraded due to construction of a number of barrages for irrigation purposes, clear felling and lack of fresh water supply, lack of tidal flushing of the degraded areas, release of pollutants from various domestic and industrial sources, changes in water quality, Illegal sand mining etc. <> The associates grow along with mangroves but lack typical characteristics. According to Tomlinson (1986) ¾When they grow larger (less susceptible to predators) they move to more open habitat such as seagrass and coral reefs e.g. Phyto-sociological studies of true mangrove species have also been done and classified into different frequency classes. At present, all these species are at serious risk as no systematic attempt has been made to conserve them.

This enhances a well developed mangrove ecosystem throughout the belt of costal area. from mangrove associates in leaf traits and osmotic properties. Global mangrove deforestation continues but at a much reduced rate of between 0.16 percent and 0.39 percent annually. The mangrove flora is unique in nature due to its restricted distribution only to the tidal zones. Nadu, Karnataka and Kerala (MoEF, 1987).

The mangrove ecosystem is considered as an attractive biodiversity hotspot that is intensively studied in the hope of discovering new useful chemical scaffolds, including those with potential medicinal application. Consolidation of data pertaining to the extent and According to the estimate of this study, the extent of mangroves of Kerala is 2502 ha out of which 1189 ha belongs to the state but 1313 ha is under private ownership. Generally, mangrove species are categorized as ‘exclusive’ species that are limited to the mangrove environment (referred a… According to another estimate, Kerala once supported about 700 km 2 mangroves and what we see now are only relics of a great past (Ramachandran et al., 1985). These data can be used to drive the mangrove research agenda particularly as it pertains to improved monitoring of mangrove carbon stocks and the establishment of baseline local mangrove forest inventories required for payment for ecosystem service initiatives. ResearchGate has not been able to resolve any citations for this publication. Indonesia remains by far the largest mangrove-holding nation, containing between 26 percent and 29 percent of the global mangrove inventory with a deforestation rate of between 0.26 percent and 0.66 percent annually.
