Site description Situated 65 km south-west of Pofadder, this site consists of five farms; Bitterputs (107 and 110) (29,555 ha), Bitterputs 111 (3,224 ha), Bosluis (5,101 ha), Kanaip (6,175 ha) and Oorstoot (1,485 ha). Bitterputs (107 and 110) forms the central portion of the IBA and consist mainly of flat gravel-plains with a red dune system that runs from north to south in the central and western portion of the property. Coarse, pale red sandy soils and red dunes form the southern portion of the fossil Koa river valley. Towards the east, sandy plains comprising perennial desert grassland and granitic gravel-plains occur.

The koppies hold shrubs, e.g. Adenolobus and Rhus, especially on the mid-slopes and peaks, while the cobble-strewn bases are often covered with melkboom Euphorbia. The drainage lines support taller woody vegetation, such as Euclea, Ozoroa, Acacia and Tamarix shrubs. The gravel-plains are covered with a variety of sparse dwarf shrubs.
