Mangroves – The Sentinel of Environment
Mangrove is a shrub or small tree that grows in coastal saline water. It is found worldwide in the tropical or sub-tropical regions mainly between 25 degree N and 25 degree S.

Special features & benefits of Mangroves
· Natural defence system of coastline :- Mangroves grow along the boarder line of landmass and brackish sea water where no other plant survives. River and land sediments is trapped by the root system of mangroves which protect coastline from erosion. This natural filtering process prevents harmful sediment reaching coral reefs and sea grass meadows. It also protect communities at risk from rise in sea-level due to climate change, Tsunami and cyclones. It helps in controlling surge level of tidal waves and protect coastal habitation.
· Effective Carbon sink :- Mangrove forest help in controlling global warming by removing Carbon dioxide from the atmosphere and storing within the plant in greater quantities and for longer period than other forest. These forest held up nearly four times more carbon than other tropical rain-forest. This unique feature of Mangroves make them planet’s best carbon scrubbers.
· Rich in bio-diversity :- Mangroves are salt--tolerant trees which contain a complex salt filtration system and sturdy root system to survive in saline water. They are adapted to the low oxygen conditions of waterlogged mud. Due to this special characteristic mangrove forest is home to a wide varieties of fish, crab & shrimp species, molluscs and sea turtles. They provide natural habitat for nesting, breeding and thriving for birds and aquatic species.

This is also famous for the Royal Bengal tigers. Due to its rich bio-diversity the Sunderbans has been included in the list of UNESCO World Heritage Site in tear 1997.
· Baratang island at Andaman is also famous for its mangrove forest which can be visited while going to Limestone caves.

In fact Mangroves are true sentinel of Environment in coastal area and an ecological hotspot. We must save mangroves to save environment and life within.
