Robertson Karoo is a semi-aridvegetation type, restricted to sections of theBreede River Valley,Western Cape Province,South Africa. It is a subtype ofSucculent Karoo (geographically an extension of the "Little Karoo") and is characterised by the dominance of succulent plant species, and by several endemic plants and animals.

Location and extent

[edit]

This vegetation type occurs in several large patches within theBreede River Valley, in theWestern Cape Province ofSouth Africa. It occurs in the area between Worcester in the north-west, Ashton in the east, and the Riviersonderend mountains in the south.

Landscape and climate

[edit]

Robertson Karoo typically consists of low hills and flats covered in small succulent vegetation, usually growing on rocky shale-based soils. The climate is semi-arid due to the region lying in the rainshadow of the large mountain ranges to the south-west, but the rainfall does tend to occur mainly in winter.

This vegetation type has a large number of endemic species and several endemic genera.^[1]
