2016 Oxbows CSIR Albers Equal Area
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.

South African Inventory of Inland Aquatic Ecosystems
Mapping the locality and attributes of inland aquatics is essential across the country, which in turn can be used along with other data to identify key inland aquatic features for conservation National Freshwater Inventory (2016) and National Biodiversity Assessment (2018)

South African Inventory of Inland Aquatic Ecosystems
(
WWW:LINK-1.0-http--related
)
A South African Inventory of Inland Aquatic Ecosystems (SAIIAE) was established during the National
Biodiversity Assessment of 2018 (NBA 2018). The SAIIAE offers a collection of data layers pertaining to
ecosystem types and pressures for both rivers and inland wetlands.
The SAIIAE builds on previous efforts while also introducing improvements and several new elements. An
inventory of inland aquatic ecosystems responds to a multi-stakeholder need for the planning, conservation
and management of these systems, as mandated by a number of legislative Acts, including the South
African National Water Act (NWA) and the National Environmental Management: Biodiversity Act (NEMBA).
This report provides a full overview of historical efforts in the inventorying of inland aquatic ecosystems, as
well as efforts undertaken between 2015 and 2018 in the update of data layers associated with river and
inland wetland ecosystem types for the NBA 2018.
