- Statement
-
The ecosystem status of all vegetation types was established across South Africa as a whole, as part of the 2004 National Spatial Biodiversity Assessment (Driver et al., 2005).
For each vegetation type in the 2004 SANBI SA vegmap Beta04 version:
Ecosystem targets were calculated using best available science (targets indicate how much of that vegetation type needs to be conserved).
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.
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.
