Site description This vast complex of wetlands lies on the flood-plain of the Bemarivo river, and includes water-bodies near Mahajamba (Lakes Andranolava, Mafana and Faly, and the Bekapila flood-plain), water-bodies near Port-Bergé (Lakes Besisika, Matsaborifanjava, Ampahaka and Ampombitika-Bezanadaoka—the only large and deep lake—and the Sofia river), and Lake Bekatra near Antsohihy. Lake-margin vegetation includes beds of Cyperus and reed Phragmites. Agriculture predominates in between the wetlands, particularly rice-fields, but there are also areas of dense, dry deciduous forest, savanna (sometimes with palms Bismarckia), and areas dominated by the non-native bush Mimosa pudica.
