Cattle distribution data from GPS collars, and spatial patterns of defoliation and pasture productivity are being used to compare the effectiveness of reducing paddock size to that of installing additional water points in large paddocks, to spread grazing pressure more evenly across the landscape. Uneven grazing distribution is a common problem in extensive savanna rangelands, causing poor overall forage utilisation, localised areas of very heavy use, and rendering many grazing management practices ineffective. Achieving more even landscape use is seen as an integral part of sustainably increasing livestock production. Early results indicate that smaller paddocks are more effective in achieving greater use of the landscape as a whole. However, within smaller paddocks, preferred areas remain the focus of much grazing activity, highlighting the need for additional ways of minimising these grazing impacts.
