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.

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.
