Summary Umvoti Vlei lies 11 km due south of Greytown. It forms the headwaters of the Umvoti River. There is some open water at the lower end of the vlei, where clay soils impede drainage. The wetland areas are good for Wattled Crane Bugeranus carunculatus and Grey Crowned Crane Balearica regulorum, which winter here in large numbers. The wetland also holds a small population of African Marsh Harrier Circus ranivorus.
