A Ramsar-listed wetland sanctuary on Gauteng's East Rand, renowned for exceptional waterbird diversity.
Marievale Bird Sanctuary
Marievale Bird Sanctuary is a protected wetland reserve in Gauteng, South Africa, situated on the East Rand along the southern half of the Blesbokspruit, a major perennial river flanked by broad floodplains. Covering roughly 1,526 hectares, the sanctuary was formally established as a reserve in 1978 and later expanded, and is internationally recognized as a Ramsar site, reflecting its global importance for wetland conservation.
The sanctuary's defining character is shaped by open water pans, dense reedbeds, and adjacent grassland, creating habitat for an exceptional variety of waterbirds, waders, and other wetland-dependent species. Almost 300 bird species have been recorded, making it one of the most important inland birding destinations in the Gauteng region and a key stop for birdwatchers seeking species ranging from large herons and flamingos to secretive crakes and migrant shorebirds.
Beyond its birds, Marievale also supports mammals such as blesbok, southern reedbuck, yellow mongoose, and otters, highlighting its broader ecological value. Despite ongoing threats from surrounding industrial and urban pressures, the sanctuary remains a vital refuge for wetland biodiversity in a heavily developed part of South Africa.
