Site description The site encompasses Lake Manyara National Park, the part of the lake which falls outside the park and the Marang Forest Reserve on the escarpment above the park. Lake Manyara is 40 km long by 13 km wide and is oriented almost north–south along the western margin of the Eastern Rift, some 85 km south of Lake Natron (TZ031). The escarpment rises 900 m above the level of the lake leaving a narrow western shore of AcaciaCommiphora woodland with sizeable stands of groundwater forest dominated by Trichilia roka with Croton macrostachyus and Cordia africana. The lake is generally saline (pH levels vary with rainfall) with areas of fresher water where perennial streams flow into the lake. The largest of these is the Simba river which drains from the Ngorongoro Highlands to the north-west and the Makayuni river which flows in from the east. There are extensive swamps in the north and smaller ones elsewhere associated with the minor rivers flowing off the escarpment. The level of the lake fluctuates considerably between seasons and between years and is occasionally reduced to a relatively small saline pool. On the escarpment, the Marang forest is composed of montane vegetation dominated by Olea capensis, Albizia gummifera, Podocarpus latifolius and Macaranga sp. The drier plateau forest contains Bersama abyssinica and Clausena anisata with Croton sp. and Olea africana as canopy dominants.
