Assessing intra-seasonal land surface change and long term trends in the succulent Karoo biome using coarse resolution satellite and interpolated rainfall surfaces
The Succulent Karoo is a biodiversity hot spot situated along the west coast of southern Africa. While it is predominantly recognized as a west coast vegetation type its borders stretch as far east as Steytlerville in the Little Karoo. The area contains the largest number of endemic succulent …

Impacts of degradation on critically endangered Oudtshoorn Gannaveld
In the Succulent Karoo biome of South Africa vegetation degradation by overgrazing is a recognized threat to biodiversity. In the eastern Little Karoo region of the Western Cape Province, ostrich farming has degraded large areas of natural vegetation, particularly in the Gannaveld habitat of the …
