Site description Mabamba is an extensive marsh stretching through a long narrow bay, fringed with papyrus Cyperus papyrus towards the main body of Lake Victoria. Miscanthus and Cyperus species dominate, but there is a narrow open water channel and a small patch of water-lilies Nymphaea. There are also areas of sedge Cladium, and sometimes drifting papyrus swamp islands. The Bay forms part of Waiya Bay, south-west of Nakiwogo Bay; these are all to the west of Entebbe International Airport. This IBA is one of the best marshy areas along the northern shores of Lake Victoria.
