The Kammarieb Private Reserve measures roughly 1 500 ha and is located about 35km west of the town of Philippolis in the Free State Province.  On its western side Kammarieb borders on the Vanderkloof Dam - the second largest dam in South Africa.  The Vanderkloof Dam is situated on the Orange River which forms the border with the Northern Cape Province.

Topography of the area ranges from rolling hills and ridges to valleys and dales with altitude ranging from 1410 m to 1230 m.

Kammarieb Private Reserve is situated in the Great Karoo with annual precipitation ranging between 200 mm (in the West) and 400 mm (in the East).  Lying on the eastern rim of the Great Karoo annual rainfall on Kammarieb is closer to 400 mm.  Rainfall statistics indicate that 3 out of 10 years will experience substantial above normal precipitation (+20% of average) whereas 2 out of 10 years will experience substantial below normal precipitation (-20% of average).  The rainy season runs from October to April with January, February and March the wettest months.  Of significance is that on average only 12 days per annum will experience precipitation of more than 10 mm and only 2 days more than 30 mm.

Average annual temperature is 18.9 ‘C with an average maximum in January of 34 ‘C and an average minimum in June of 4.6‘C.

Geologically the area consists mainly of dolerite hills and ridges (intrusive rock formations) with valleys and dales characterised by grey or red-brown mudstone and shale of the Beaufort Group.

The region that Kammarieb is situated in has been labelled by Acocks (1953) as False Upper Karoo veld type and later by Hoffman (1996) as the Eastern Mixed Nama Karoo veld type.  This area represents an ecotone between the Nama Karoo in the west and the grass veld biome in the east and north.  Only 1% of this veld type is currently protected in reserves. 

Vegetation on Kammarieb has been classified and mapped into 6 main communities.  This was done in order to better understand and determine the grasing and browsing capacity of the area and as a management tool.  Each of these communities has a unique grasing/browsing profile and some may represent specific habitat for selected animals.
