The Table Bay Nature Reserve forms the southernmost buffer area of the Cape West Coast Biosphere Reserve, and links it to the edge of Cape Town's city centre. It also contains a large portion of the critically endangered lowland habitats remaining in Cape Town.
The central feature in the Table Bay Nature Reserve is the Rietvlei wetland system. The Rietvlei Wetlands and Milnerton Lagoon were proclaimed as a Nature Area on 3 August 1984, in proclamation number 1632 of Provincial Gazette No. 9345. The Nature Reserve is partly owned by the City of Cape Town and the World Wildlife Fund for Nature – South Africa, who own two of the Erven. The City of Cape Town manages these two Erven on a 99-year lease for the purposes of nature conservation.[1]
