As part of two major grazing trials in sub-tropical Queensland, runoff and soil movement were recorded at a detailed (m2) and landscape (ha) scale. The effect of grazing pressure on soil movement by its effect on vegetation, and hence runoff, was determined. A significant effect of stocking rate on soil movement occurred within a landscape, even during the worst drought on record. At one site spatial variation in hydrology and soil movement within the landscape was recorded, although this was not translated into total soil loss from the catchment. The effect of this source/sink movement within a landscape will have important consequences for the future stability of the landscape and the vegetation states that occur.
