Here are some maps of Critical Biodiversity status for four of the municipalities falling within the Cape Action Plan for the Environment (C.A.P.E).  I worked as the cartographer assembling layers compiled by Gen Pence from various sources. 

As you will see two of the maps are still in the early draft form where I had included a suggestion of relief.  However this was seen to be confusing the interpretation of the key owing to the shadows altering the classification values.
The original shapefiles are available for download from the BGIS website.
