Renosterveld Special Habitats 2003 (special_habitats_dd.shp)
CAPE Lowlands Renosterveld – Special Habitats. Silcrete and quartz patch locations were derived from the Cape Lowlands Renosterveld vegetation map (see attached metadata). Only those with remaining natural vegetation were included. Wetlands were derived from the WCNCB ‘sensitive wetlands’ GIS layer and the Freshwater GIS component of C.A.P.E. Note that the wetland layer is not complete – many wetlands that are present on the ground are not represented in this layer as they are currently not mapped anywhere. Silcrete patches, quartz patches, and wetlands in the Cape Lowlands Renosterveld Project’s central domain. Note that NO special features
occurring in the buffer area (see planning domain infosheet) are included.

As part of the Cape Lowlands Renosterveld Project, selected habitats were identified as special habitats and mapped as follows:
1. Locations of silcrete and quartz patches (characterised by specific vegetation types) were derived from the vegetation map generated as part of the project Only the portions of remaining intact vegetation (ie not transformed by agriculture or development, as per the ‘remnants of natural vegetation’ GIS layer) were included as special habitats.
2. The locations of wetlands are based on data from two sources:
1. the WCNCB ‘sensitive wetlands’ GIS layer and
2. a GIS layer of wetlands compiled by the C.A.P.E. Freshwater component (1999), based on digitised 1:50 000 topographic mapsheets (Surveys & Mapping). No metadata was available for this layer.
Dams were removed from these layers, and the ‘type’ of wetland called ‘erosion’ was also removed. Once the data layers had been combined and cleaned, the result was checked against the 1:50 000 topographic mapsheets to verify that no major wetland features had been excluded.
