Site description The site comprises the coastal fringe of the large bay in south-west Mayotte. It extends from Poroani village (in the north) to Karoni hamlet, including the largest extent of mangrove on Mayotte (and indeed the Comoro archipelago), the landward strip adjacent to it, and also some intertidal mud. The strip is about 13 km long, and the mangrove belt reaches a maximum thickness of about 800 m. The landward side is cultivated with bananas and coconut, with a woodland of large trees (especially Heritiera sp. and Erythrina sp.) bordering the coast. The coastal plain is almost flat for up to 1.5 km inland. The towns of Chirongui and Tsimkoura lie a few hundred metres inland on this strip.
