Renosterveld Ecosystem Status (Conservation_status_dd.shp)
CAPE Lowlands Renosterveld Natural Vegetation Remnants – Conservation status. This data layer shows ecosytem status for vegetation types occurring in the Cape Lowlands Renosterveld planning domain (see separate infosheet for planning domain). Ecosystem status indicates whether a particular vegetation type is ‘critically endangered’, ‘endangered’, ‘vulnerable’ or ‘least threatened’. These categories are based on biodiversity targets (calculated for the National Spatial Biodiversity
Assessment, NSBA, 2004) and on the extent (% area) of natural vegetation remaining for that particular vegetation type.

- Statement
-
The conservation status of all vegetation types was established across South Africa as a whole, as part of the National Spatial Biodiversity Assessment, 2004.
For each vegetation type in the 2004 NBI ‘SA Vegmap Beta04’ version:
1. conservation targets were calculated using best available science (targets indicate how much of that vegetation type needs to be conserved)
2. the extent (percentage area) of remaining natural vegetation within each vegtype was calculated using the National Land Cover, 1996. Remaining natural vegetation refers to those areas that have not been transformed through cultivation, urban development etc.
3. Conservation status for each vegetation type was assigned as follows:
If % remaining area of vegetation < the target, then vegtype is critically endangered
If % remaining area of vegetation < 60% of original extent, then vegtype is endangered
If % remaining area of vegetation < 80% of original extent, then vegtype is vulnerable
If % remaining area of vegetation > 80% of original extent, then vegtype is least threatened.
