Site description The park protects the western shores of Lake Volta and the intervening country between the Sene and Obosum arms, which form the northern and southern boundaries respectively. Most of the level land is covered with various types of Sudanian woodland, but the south of the park is clearly in the forest/savanna transition zone. The riparian forests which lined the Volta in the past were flooded by the Akosombo Dam in 1964; the shores of the resulting lake are covered mainly by grass and sedges. The main forest remnants (of dry semi-evergreen forest) are to be found in the south-west, away from the Lake. Other important habitats present include laterite bovals ("bowals" in White 1983) and sandstone outcrops. The park is difficult of access and there are no roads.

Other biodiversity There is a small population of Trichechus senegalensis (VU) along the lake-shore, as well as Hippopotamus amphibius. The south-west is especially rich in large mammals, including Loxodonta africana (EN), and several forest monkeys are apparently surviving in small forest patches (e.g. Colobus vellerosus VU, Procolobus verus LR/nt, Cercocebus atys LR/nt).
