Main Body
Mangroves are salt tolerant plants found in the ecotone areas (boundary between land and water body).
Geographical factors & Mangrove vegetation
1Estuaries on the east western coast: Rich ground for mangrove plants, as fresh river water replenishes nutrients regularly.
2Deltas on eastern coast: Ideal ground for mangroves Eg: Sundarban mangroves (Gangs & Brahmaputra rivers)
3Shape of coast lines: Coast with indentations are more favourable Eg: eastern coast
4Coast line of emergence & submergence more favourable less.
5Brackish water: Neither pure fresh water nor pure salty water is needed.
6Tidal currents: regularly intempts the waters & increase fertility of soil.
Climate change & threat to mangrove vegetation
1Severe intensity of cyclones destroy the mangroves.
Eg: Hudhud cyclone in Vizag
2Temperature of ocean water increasing → may harm mangroves as sodaptation takes time.
3La Sever rain & flooding: Changes salinity of water bodies → may harm plants.
4Variability in river water draining in coastal area due to glacial melting.
5Steps that can be taken
Adaptation measures by community living nearby.
Global cooperation: Reducing climate warming (es. Paris deal signt adherence)
Satellite imagery & planning.
Mangroves are unique vegetation & protect coasts from have of cyclones. They should be preserved with great priority.
