Mangroves of Western South Atlantic (Tropical and Subtropical WSAOBIS, BRAZIL)
'Despite their strategic importance, mangroves are under threat worldwide. They are sacrificed for salt pans, aquaculture ponds, housing developments, roads, port facilities, hotels, golf courses, and farms. And they die from a thousand indirect cuts: oil spills, chemical pollution, sediment overload, and disruption of their sensitive water and salinity balance. Calls for mangrove conservation ... gained a brief but significant hearing following the 2004 Indian Ocean tsunami. Where mangrove forests were intact, they served as natural breakwaters, dissipating the energy of the waves, mitigating property damage, perhaps saving lives. Post-tsunami, the logic of allowing a country's mangrove "bioshields" to be bulldozed looked not just flawed but reprehensible. … Mangrove forests are the supermarkets, lumberyards, fuel depots, and pharmacies of the coastal poor. …' (Warne & Laman, 2007).
WSA OBIS has identified that for most of its covering area there is still a great lack of ready assessable online datasets with mangrove forests or biotopes available. For most potential users of this information the indication to be a mangrove dataset is by the occurrence of the large and characteristic trees species – Rhizophora mangle, Rhizophora harrisonii, Avicennia schaueriana, Avicennia germinans and Laguncularia racemosa (FAO 153, 2007). The datasets have been arbitrarily divided following the 4 main large political regions of Brazil and also facing the Atlantic Ocean: North (Amapa and Para States), Northeast (Maranhao, Piaui, Ceara, Rio Grande do Norte, Paraiba, Pernambuco, Alagoas, Sergipe and Bahia States), Southeast (Espirito Santos, Rio de Janeiro and Sao Paulo States) and South (Parana and Santa Catarina States) (Obs.: in Rio Grande do Sul State there are no mangroves).
