| Madagascar mangroves : ウィキペディア英語版 | Madagascar mangroves The Madagascar mangroves are a coastal ecoregion, in the mangrove forest aquatic biome, of mangrove swamps in rivers and estuaries in Madagascar, mainly on the west coast. ==Location and description== The mangrove swamps are located in flat coastal areas where the ocean tides wash salt water high into the mouths of rivers which are bringing nutrient-rich soil down to the coast. For mangroves to thrive there also needs to be some natural feature such as hilly terrain or a coral reef to shelter the coast from ocean storms and the monsoons. In Madagascar they are mostly found on the more sheltered west coast and the largest areas are in the estuaries of the Betsiboka River (in Bombetoka Bay near the city of Mahajanga), Besalampy, and the Mahajamba, North Mahavavy and South Mahavavy Rivers, and near Maintirano.〔http://ramsar.wetlands.org/Portals/15/MADAGASCAR.pdf〕 As well as being home to a rich variety of birds and fish the swamps also hold river estuaries in place and prevent river mud being washed into the sea and thus suffocating coastal coral reefs. The climate is warm all along the coast but more humid in the north.
