Site description The site consists of Lakes Ambanja, Vasily, Belongo and Manapatanana, located near Ambato-Boeni, and of Lakes Amparihibe, Mangabe, Bekopoly, Ambariasara and Bevoatavo, in the area of Maevatanana. The general area consists of a number of very large depressions, mainly covered (near Ambato-Boeni) by seasonal marshes which have been converted to rice-fields and other cultivation, and (near Maevatanana) by marshes and lakes. The main rivers are the Kamoro river, which flows across the Ambato-Boeni area, and the Betsiboka river, which flows west from Ambato-Boeni then south towards Maevatanana and which feeds the south of this area. The vegetation of the lakes includes beds of Cyperus, reedbeds of Phragmites, floating expanses of water-lily Nymphaea, non-native water-hyacinth Eichhornia and water-fern Azolla. On adjacent hills there are bushes of Zizyphus and Strychnos.
