Site description The Wembere river rises in hilly country at 06°S, south-east of Tabora and south-west of Singida. It forms the major river of the Eyasi internal drainage basin and flows north through the Wembere flood-plain before turning north-east at Lake Kitangire (TZ026) and thence into Lake Eyasi (TZ023). The Wembere flood-plain consists of open grassland intersected by drainage lines on the black cotton soil. Stands of Acacia seyal and Acacia drepanolobium grow around the edge of the plain, their exact distribution depending on the extent of waterlogging in the wet season. There are areas of Aeschynomene which die back during the dry season and produce dense stands after heavy rains.
