Site description The Lüderitz Bay island complex consists of four coastal islands, all situated within one kilometre of the shore. The rocky shoreline, including Lüderitz fishing harbour, is included within the IBA. Halifax Island (3 ha) is located at the south end of Guano Bay near Diaz Point, a promontory at the western entrance of Lüderitz Bay, and one of the first landfalls of Portuguese explorers in the 1400s. The whole area lies within the intense upwelling cell off the Lüderitz coastline, creating a node of high marine productivity resulting in large congregations of seabirds. The other three islands, Penguin (36 ha), Seal (44 ha) and Flamingo, lie to the east of Halifax, within Lüderitz Bay. The islands hold some abandoned guano-scrapers’ buildings. They support no vegetation other than subtidal kelp and other seaweed on their shores.
