The spatial representation of the regional setting at Level 2 of the Classification System for Wetlands and other Aquatic Ecosystems in South Africa.

Coverage of all the conservation areas for which CapeNature is the managing authority, and private conservation areas (such as contract nature reserves and WWF-SA land) for which CapeNature has a management agreement with the private landowner.

A sub-version of the National Wetland Map 5. National Geo-spatial Information (NGI) data from 2006 and 2016 was unioned into a single feature class. This was further unioined with the Estuaries Functional Zone, Working for Wetlands data, peatlands data, and the 1 m buffers of the NGI spring points (referred to as the ADD1 feature class). This layer was further split into provincial data sets for attending to slivers, checking names and assigning HGM units to a polygon. This layer should not be used as the final National Wetland Map 5. For the final National wetland map 5 please refer to the layer National Biodiversity Assessment 2018 Artificial Wetlands AEA.

NBA 2018 Rivers assessment layer. This data set is part of the first version of the South African Inventory of Inland Aquatic Ecosystems (SAIIAE) 2018 released in July 2018. A second update of the SAIIAE 2018 was issued with the launch of the NBA 2018, and includes the condition, Ecosystem Threat Status (ETS) and Ecosystem Protection Level (EPL) information for the rivers. The river lines data set is associated with the National Wetland Map 5 (NWM5) issued with the SAIIAE version 1 and 2. Dr Lindie Smith-Adao generated this rivers data set by 2018/06/29.

The Confidence map was compiled to identify areas where wetland extent and HGM units attained at a higher level of certainty compared to other areas. Higher levels of certainty are associated with areas that have been visited in-field by a wetland specialist(s) over multiple seasons and cycles of the hydroperiod of a wetland, and accurately represented in the dataset. This data set is part of the first version of the South African Inventory of Inland Aquatic Ecosystems (SAIIAE). The confidence map should always be read with the National Wetland Map 5 (NWM5) which was issued with the SAIIAE version 1 was generated on 2018/06/29 by Heidi van Deventer. NWM5 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).

Coverage of all the conservation areas for which CapeNature is the managing authority, and private conservation areas (such as contract nature reserves and WWF-SA land) for which CapeNature has a management agreement with the private landowner.

The National Wetland Map version 5 (NWM5) shows the distribution of inland wetland ecosystem types across South Africa and includes estuaries and the extent of some rivers. A confidence map was compiled to identify areas where wetland extent and hydrogeomorphic (HGM) units (which contributed to defining the inland wetland ecosystem types together with the regional setting) attained at a higher level of certainty compared to other areas. Higher levels of certainty are associated [code 5 in field Confidence_nr] with areas that have been visited in-field by a wetland specialist(s) over multiple seasons and cycles of the wetland hydroperiod, and are therefore more accurately represented in the dataset. Codes 4 to 1 indicate lower levels of confidence that the extent and HGM unit are represented well. If the Estuaries are used, please cite Van Niekerk et al., 2019. Technical Report of the Estuarine Ecosystems for the NBA 2018.

Updates will be incorporated into the National Wetland Map 6 which is under way.
