THE MANGROVE GUINNEENNE AN ​​ENDANGERED ECOSYSTEM IN THE SANGAREAH BAY

Oceanographic

Guinea is home to a unique heritage in terms of biodiversity in West Africa, especially in its relics of dense humid forests classified as areas of high biodiversity. Mangroves, coastal forest ecosystems, mainly tropical, constantly changing, are generally located around areas with high population density.The objective of this study was to assess the degradation of the mangrove in the bay of Sangaréyah, by estimating the decrease in its area, to identify the main sources of pressure on the ecosystem of the bay. This present work, based on previous work carried out in the different countries, is based on a large bibliographic inventory aimed at assessing the state of mangrove degradation in Guinea. The results obtained allow us to conclude that the scale of the exploitation of firewood, the extraction of salt and the production of rice are the main causes. The consumption of a large quantity of wood would also explain, by the fact, that all the smoking techniques practiced in the Bay use Rhizophora (Kinsi) as firewood. It has been established that the "pani" method is one of the factors of degradation of the vegetation in the bay.
