The Heuningnes estuary
(34°43' S;
20°7' E)
is the southernmost estuary in South Africa, situated near Cape Agulhas. The catchment area that feeds this system is approximately 1 400 sq. km. About 41% of the Heuningnes catchment was under agriculture. Most of this was temporary commercial dryland agriculture, improved grassland and some commercial forestry. About 2% of the catchment was degraded, mostly degraded shrubland. Approximately 56% of the Heuningnes catchment was natural, mostly shrubland, grassland, bushland, and wetlands and waterbodies (Zoetendalsvlei). There was little (less than 1%) urban development in the Heuningnes catchment and most of this comprised residential and industrial development. Major towns in the catchment include Bredasdorp, Napier and Elim.
