Site description The site is located 35 km west of Belo-sur-Tsiribihina. The Tsiribihina delta includes the shoreline, sandbanks, lagoons, coastal mudflats, mangrove forest, saltflats, and areas of marsh and of dry land. The mangrove is 2–4 m high, and dominated by trees of Avicennia, Rhizophora, Ceriops, Bruguiera and Sonneratia. The saltflats often flood during the rainy season. The marshy areas are dominated by sedge Cyperus, reed Phragmites and non-native water-hyacinth Eichhornia, while the dry land is covered in savanna, with palms. The wetlands of the upper Tsiribihina river include the neighbouring lakes, and the Sahajilo and Mania rivers. Lake Kimanomby, west of Ambohibary village, is surrounded by dense, dry deciduous forest (Ambovondambo Forest to the west, Marotapia Forest to the east). There is no floating vegetation, but the margins are covered by Eichhornia. Lake Masoarivo, west of Masoarivo village, is small, shallow and red due to muddy sediments. Lake Hima has floating vegetation and is surrounded by fishermen’s camps. In the Tsiribihina valley, between the towns of Miandrivazo and Malaimbandy, there are several lakes and a vast area of marshes, dominated by sedge Cyperus and reed Phragmites.
