"Although PC2 values between Wonderkrater and Tswaing are therefore not translatable to absolute precipitation values, they nevertheless seem to reflect parallel moisture trends in both sequences, e.g., an early Holocene dry phase and a general upward trend during the middle and late Holocene (Fig. 3A). As previous estimates for Tswaing were largely intuitional (Scott, 1999a,b), this is the best pollen-based moisture index available now"

A Late Quaternary Pollen Record from the Transvaal Bushveld, South Africa
Abstract Pollen spectra from cores of organic spring deposits from the Transvaal provide evidence for the climatic evolution of the province during the last 35,000 yr B.P. or more. The past climatic phases are derived from palynological reconstructions of past vegetation types by comparison of fossil pollen data with modern surface pollen spectra from various localities. Evidence is provided for an early moist, cool phase with relatively mesic bushveld and expanded montane forest in the central Transvaal, followed by a drier period with drier bushveld which probably lasted until approximately 25,000 yr B.P. During the next phase, which at the latest ended about 11,000 yr B.P., the temperatures were probably 5°–6°C cooler than at present. At that time bushveld vegetation in the central Transvaal was replaced by open grassland with macchia elements. Climatic amelioration came and semiarid savanna returned to the plains, at first gradually and then developing into a warm Kalahari thornveld-type vegetation.
