Springs (DRDLR:NGI, 2006 and 2016). The springs data was extracted from the hydrological point shapefile data issued by the DRDLR-NGI in September 2015. Springs can indicate potential origins of seep wetlands or rivers, and were used by the data capturers to assess sources of wetlands. It also provides the location of inland aquatic features that were not assessed in the NBA 2018. Please see Van Deventer et al. (2018) for more information.

This data set is part of the National Wetland Map 2 (NWM2). Data from the National Wetlands Map 1 was combined with the 1:50 000 Farm dams features (DWAF 2004) to produce NWM2. National Wetland Map 2 that was divided into three GIS layers: wetland, natural waterbody and artificial waterbody.

Peatlands mapped as having turned desiccated or have burnt

Artificial wetlands of the South African Inventory of Inland Aquatic Ecosystems (SAIIAE). This data set is part of the Inventory released with the launch of the NBA 2018. National Wetland Map 5 includes inland wetlands and estuaries, but are associated with river line data and many other data sets within the South African Inventory of Inland Aquatic Ecosystems (SAIIAE). Please ensure you obtain the full geodatabase and relevant reports to understand the appropriate use of the data. Appropriate use and a disclaimer is provided under the relevant reports below.

Waterfalls Waterfalls were extracted from the DRDLR:NGI point data and supplemented by Heidi van Deventer from known waterfalls and those indicated by experts across the country.

Thermal springs (Olivier and Jonker, 2013). A thermal springs xlsx file was obtained for the purpose of guiding wetland mapping for the National Biodiversity Assessment (NBA) 2018 project. These coordinates were converted to points.
