Site description This coastal area comprises a private nature reserve of 400 ha and a saltworks. It lies adjacent to the sea on the central Namib desert coast and has been extensively altered to create numerous evaporation ponds. Immediately inland lie the gravel-plains of the Namib desert. The saltworks are situated about 7 km (4 miles) north of Swakopmund, off Route 76 to Terrace Bay. Production of the concentrated brine at the saltpan, known as Panther Beacon, began in 1933, but by 1952 the salt source was exhausted. Seawater has since been pumped into open evaporation and concentration ponds from which crystallized salt is removed with mechanical scrapers. The pans are shallow and of varying salinity. A large wooden commercial guano platform covering 31,000 m² has been built in one of the northern pans. Apart from a few halophytes, the saltworks are devoid of vegetation.
