Mangrove Swamps If there are no mangrove forests, then the sea will have no meaning. Since these estuarine swamps are constantly replenished with nutrients transported by fresh water runoff from the land and flushed by the ebb and flow of the tides, they support a bursting population of bacteria and other decomposers and filter feeders. The term mangal is used by researchers, authors, and the general public in the United Kingdom and other countries. By retaining the excess rainwater or floodwater, swamps often protect dry lands from excessive flooding.

[NEW DELHI] Dense mangrove forests growing along the coasts of tropical and sub-tropical countries can help reduce the devastating impact of tsunamis and coastal storms by absorbing some of the waves’ energy, say scientists. Despite the state government and High Court-appointed mangrove protection and conservation committee ordering transfer of all mangroves to the Forest Department (they are in the jurisdiction of collectors, etc), they have not been handed over so far, Kumar pointed out. Growing in a salty environment means the mangroves lack competition. Re-vegetation programmes are implemented two years after the final felling as required. 50-metre wide belt of mature mangroves can reduce 1 metre high waves o reduce the total wave energy of 1 metre waves, a 150 metre wide mangrove forest belt is needed. Since 1998, the U.S. government has extensively mapped coral reefs to track their decline. Losses are being driven by a suite of other human threats as well, however, including over-harvesting and deforestation; agricultural, urban and industrial runoff; oil spills; and poorly managed dredging and coastal development. mangal (Macnae 1968), and mangrove swamp (Odum et al.1982). Reduce stormwater runoff. Homeowners can install water catchments or rain gardens and use rain barrels to collect rainwater that would otherwise be diverted to storm drains. Limited losses have occurred in East Africa, with only an 8% decline between 1980 and 2005. An estimated 38% of global mangrove loss can be attributed to the clearing of mangroves for shrimp culture, while another 14% can be blamed on other forms of aquaculture.
