The conservancy covers the entire districts of De Aar, Philipstown and Hanover in the south-eastern portion of the Northern Cape Province. Although the land in the IBA is primarily used for grazing and agriculture, it includes the suburban towns of De Aar, Philipstown, Petrusville and Hanover. This huge area lies in the plains of the central Great Karoo, forming part of the South African plateau. The conservancy consists primarily of open-plain country, locally interrupted by dolerite hills and small mountain ranges which rise 200–300 m above the surrounding plateau, which varies from 1,100–1,400 m in altitude.
See Box and Table 3 for key species. This area holds vitally important populations of two globally threatened species, several biome-restricted species and important populations of other arid-zone birds. The lowland karroid plains are particularly good for Neotis ludwigii, Ardeotis kori, large numbers of Eupodotis vigorsii, Certhilauda albescens, Cercomela schlegelii, C. tractrac, C. sinuata, Emberiza impetuani and the recently recognized Certhilauda subcoronata. In the grassier areas, Eupodotis caerulescens are common. Circus maurus are occasionally seen quartering the plains, where huge numbers of Grus paradisea regularly congregate. Aquila rapax and Polemaetus bellicosus breed on the power lines in the area. The belts of riverine Acacia woodland support Phragmacia substriata, Sylvia layardi and Parus afer. Onychognathus nabouroup and Anthus crenatus occur in rocky gorges and kloofs. Other arid-zone species occurring within the conservancy are Melierax canorus, Batis pririt, Stenostira scita and Serinus albogularis. Falco naumanni have roosts throughout the area, including large roosts in the towns of De Aar, Hanover and Philipstown; they are frequently seen foraging in the conservancy in summer. Some of the dams are important roosts—during summer 1996/97, more than 850 Grus paradisea were counted on a dam in the area.
