Latest update of the Sub-Antarctic Marine Ecosystem Map

Wastewater Treatment Works (WWTW) (CSIR, 2015).

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.

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.

The most recent dams register of DWS, dated to 2016

Peatlands mapped as having turned desiccated or have burnt

Oxbow lakes from the DRDLR:NGI data issued in May 2016 for the purpose of indicating floodplain wetlands. These oxbow lakes are in some instances indicative of the floodplain depressions, however some artificial systems were also mapped as Lakes by DRDLR:NGI. The polygon features called 'Lakes' were extracted and converted to points. The data was used by data capturers to guide them in the typing of hydrogeomorphic units, and can also be used when modelling HGM units. Please see Van Deventer et al. (2018) for more information.

NBA2018_Terrestrial Ecosystem Threat Status and Protection level remaining extent layer is associated with the NBA2018_Terrestrial Ecosystem Threat Status and Protection level. While the a NBA2018_Terrestrial Ecosystem Threat Status and Protection level remaining extent provides the data for Protection level and threat status for the historical (pre 1750AD) extent of the terrestrial ecosystems, this layer shows the protection level and threat status of the current remaining extent of terrestrial ecosystems.
