Site description Situated 15 km north-east of Delareyville, these two pans, along with Klippan, are in a closed basin at 1,350 m. Barberspan is a large (6 × 4 km), permanent, shallow (max. depth 11 m), alkaline lake, which has its own small catchment of 30 km². It is the largest of a series of pans in the fossil bed of the Paleo-Harts river. The lake is fed by the Harts river and is situated in open flat grassland that can be described as a great undulating plain, much of which is cultivated for summer crops, such as maize, sunflowers and groundnuts. The nearby Leeupan is connected to Barberspan via a narrow channel. Leeupan is saline, shallow, and is subject to considerable fluctuations in water-level, drying up in most winters. This often results in conditions that are favourable for some wetland species but adverse for others.

The marginal vegetation is comprised primarily of rushes and sedges, especially Juncus and Cyperus. Aquatic vegetation is dominated by Potamogeton. Located at the ecotone of three biomes, the terrestrial vegetation consists of dry sandy highveld grassland, with Karoo invaders, and clumps of well-developed Kalahari thornveld (thickets of Acacia, Rhus and Diospyros) scattered throughout.
