The changing status of important marine fishery species in selected South African estuaries Open
This review examines the changing status of 10 estuary-dependent marine fish species in 10 South African estuarine systems, ranging from the Kosi Estuary in the northeast to the Berg Estuary in the southwest. In all of these systems, the s…

The road towards effective governance and management of marine protected areas in South Africa: evolving policies, paradigms and processes Open
The efficacy of marine protected areas (MPAs) depends on their governance and management. We review their history in South Africa and recognise four periods. Period 1 (1964–1994) provided initial protection but was based on exclusionary, p…

A systematic conservation plan identifying critical areas for improved chondrichthyan protection in South Africa Open
The International Union for Conservation of Nature (IUCN) estimates that over a third of all chondrichthyan species (sharks, rays and chimaeras) are threatened with extinction, primarily by overfishing (as target or bycatch species). Owing…
