Site description Akanda is situated 30 km north-east of Libreville and consists of two islands barely separated from the mainland by the Mamboumbé and Moka creeks and the Ntsini river, which forms the southern boundary of the site. The site borders Corisco Bay to the north and Mondah Bay to the east. Vegetation includes some dry forests on higher ground, dominated by Aucoumea klaineana, Klainedoxa gabonensis, Sacoglottis gabonensis, Librevillea klainei, Hannoa klaineana, Dacryodes buettneri and Pycnanthus angolensis. Lower down, this merges into coastal forest, typified by smaller trees such as Syzygium guineense, Cassipourea sp., Chrysobalanus icaco, and Manilkara lacera. Some flat, sandy areas are highly saline and lack vegetation. Large areas of Rhizophora and Avicennia mangroves line the creeks and the coast. At low tide vast areas of mudflat are exposed in Corisco and Mondah Bays, the rivers being confined to narrow channels.
