Sandwich Harbour is a natural lagoon which lies on the Namib desert coast, c.55 km south of Walvis Bay. One of Namibia’s four Ramsar Sites, and the country’s only marine reserve, Sandwich was once a natural harbour for whalers and fish processors who could gain access to fresh water here. Owing to dynamic geomorphological change, its sandbars and lagoons shift constantly with winter storms and longshore currents.
See Box for key species. This is the most important wetland for waterbirds in southern Africa, with counts exceeding 300,000 birds in some years. Sandwich Harbour regularly supports over 50,000 birds in summer and over 20,000 in winter. Traditionally, the northern wetland holds the highest species diversity (up to 51 species of wetland bird), while the southern mudflats hold by far the largest number of birds, dominated by terns, sandpipers, flamingos and cormorants. Shorebirds occur here at densities exceeding 7,000 birds/km², amongst the highest recorded in the world. The largest total counts at Sandwich Harbour have been 238,000 birds in January 1998 and 316,000 in January 2001.
Non-bird biodiversity: The dolphin Tursiops truncatus (DD) is seen in the lagoons, with pods of 10–20 animals not uncommon, while a non-breeding colony of c.10,000 Arctocephalus pusillus occupies the beach west of the mudflats. Hyaena brunnea (LR/nt) is a frequent visitor to the wetland.
