The remaining 27 056 ha is state-owned land. The Kammanassie Nature Reserve is situated between the coordinates 33°33’50”S and 33°37’10”S and 22°27’29”E and 23°01’55”E

There are 37 mammal species recorded for the Kammanassie Nature Reserve. A number of small antelope species occur on the reserve

Cape Mountain Zebra (Equus zebra zebra; CMZ) is the only known mammal species of special concern on the Kammanassie Nature Reserve

The region has been identified as one of the world’s hottest hotspots of biodiversity

The Mission of the GI is to take ownership of the sustainable utilisation of the unique biodiversity of the area by ensuring global recognition through partnerships, continuous awareness and responsible decision making for the benefit of all people, now and in the future.

In the Kammanassie Nature Reserve, the smaller indigenous species are known to occur in most rivers around the Kammanassie Mountain, including the Vermaaks, Marnewicks, Buffelsklip, Mill and Wilge Rivers and these rivers are thus of critical concern for the conservation of these species.

Furthermore, the Swartberg and Kammanassie Mountain Ranges are identified as National Strategic Water Source Areas. These mountain catchments provide good quality water for the agricultural sector in the rural areas and the urban areas of Prince Albert, Zoar, De Rust, Klaarstroom, Ladismith, Calitzdorp, Vanwyksdorp, Oudtshoorn and Uniondale.
