Site description The Densu delta wetland lies c.11 km west of Accra in the river valley between the Aplaku-Takuse and Weija McCarthy hills. It comprises an open lagoon, saltpans, freshwater marsh and scrub and sand-dunes. The greater part of the land is owned by the Panbros Salt Company. The wetland is fed mainly by the Densu river, which is dammed upstream (Weija dam), to supply water to the city of Accra. The dam has had profound effects on the lagoon and general hydrology of the wetland, since freshwater inflow into the wetland is controlled by the management of Weija Water Works. The water depth in the wetland varies, and can be over 2 m in some parts, during the rainy season. There is no direct outlet channel to the sea, but the lagoon often overflows into the sea after heavy rains. In other years, the Salt Company has to create an opening through the dunes to let water out of the pans. There is little vegetation on the dunes and in the saltpans; some coconut-palms Cocos nucifera fringe the dunes, while the banks of some of the pans are colonized by Sesuvium portulacastrum. Scattered stands of mangrove are found in some areas around the lagoon, while the freshwater parts of the wetland support stands of mainly Imperata, Typha and Cyperus. Scrub vegetation grows on other parts of the wetland.
