PBPTW: Ecosystem status (Cape Agulhas Municipality)
Ecosystem status indicates whether a particular vegetation type is ‘critically endangered’, ‘endangered’, ‘vulnerable’ or ‘least threatened’. These categories are based on conservation targets (calculated for the National Spatial Biodiversity Assessment, SANBI 2004) and on the extent of natural vegetation remaining (% of original area) for that particular vegetation type. This data layer shows ecosystem status for the remaining natural habitat in the Cape Agulhas Municipality (and 2km beyond its boundary).

- Statement
-
The ecosystem 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 SANBI SA vegmap Beta04 version:
1. Conservation targets were calculated using best available science (to 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. Ecosystem status for each vegetation type was assigned as follows:
If % area of vegetation remaining < the target, then vegtype is critically endangered
If % area of vegetation remaining < 60% of original extent, then vegtype is endangered
If % area of vegetation remaining < 80% of original extent, then vegtype is vulnerable
If % area of vegetation remaining > 80% of original extent, then vegtype is least threatened.
