Abstract
We studied the influence of different livestock grazing intensities and habitat types on small mammals inthe Knersvlakte, South Africa. The Knersvlakte belongs to the Succulent Karoo Biome, a biodiversityhotspot. We placed a total of 22 plots in areas of two grazing intensities (moderate and intensive) andtwo major habitat types (quartz fields and loamy soils). On these plots, we carried out small-mammal livetrapping (90 traps during four nights) and estimated the cover of different vegetation layers. In total, 140small mammal individuals from ten species were caught during 7920 trap nights. All species occurred onloamy soils, but only four in quartz fields. The small-mammal community on intensively-grazed plotswas a subset of that on moderately-grazed plots. The most abundant species on loamy soils wereMacroscelides proboscideus and Rhabdomys pumilio and in quartz fields M. proboscideus and Gerbilluruspaeba. Generalised linear models revealed that habitat type had the strongest influence on abundanceand diversity of small mammals. Vegetation cover mainly had indirect influences, via the habitat type, onabundance, diversity and the body condition of small mammals. Overall, the intensities of livestockgrazing showed no effect on abundance and diversity.
