Site description This triangular area, in the south-west of the country, comprises the marshes of the lower Kouffo river, Lake Ahémé, into which the river drains, and the ‘Aho complex’ consisting of marshes beside the Aho river, which carries water from the lake to the sea, and the coastal strip between the towns of Grand-Popo to the west and Ouidah to the east. The south of Lake Ahémé is fringed with Typha australis and the Aho supports mangroves (Rhizophora sp. and Avicennia sp.), maintained by seasonal influxes of brackish water.
