Summary The False Bay Ecology Park is centred on the Strandfontein Sewage Works, but also includes Zeekoevlei and Rondevlei Nature Reserves. The system provides a range of semi-natural habitats, including deep and shallow open water, seasonal open ponds, canals with aquatic vegetation, reed, rush and sedge-beds, bare and vegetated shorelines and islands.
