Mangrove, is a tree that grows along tropical coasts in salty ocean water. The best-known species is the red mangrove. As this type of mangrove develops, it sends down roots from its branches. Eventually, a network of many stiltlike roots supports its leafy crown above the water. Mangroves form the chief plant growth along long stretches of tropical coasts. They usually grow in places by quiet ocean water. GAMBAR HUTAN MANGROVE Rhizophora sp HUTAN MANGROVE DAN MANFAATNYA Rhizophora sp

The term mangrove refers to salt-tolerant species of tree or shrub which grow on sheltered shores and in estuaries in the tropics and some sub-tropical regions. There are about 60 species which occur exclusively in this habitat, and many non-exclusive species. Mangroves are outstandingly adapted to growing in sea water, which they desalinate by an ultrafiltration process. Mangrove roots typically grow in anaerobic sediment and receive oxygen through aerating tissue which communicates to the air through small pores (lenticels) on the aerial roots and trunks. Mangroves may occur as narrow fringes on steeper shores and river banks, or as extensive forests on flat delta-land. Within any area of mangroves there may be zones or mosaics of different biological communities, depending upon many factors. These include height of sediment surface relative to tidal water movements, and salinity and nutrient supply (which in turn are influenced by freshwater inputs from the catchment area). |
