Replacement of woodlands and native perennial grasslands with introduced annual pasture species has contributed to an increase in salinity, soil acidification and soil erosion. The establishment and improved management of deep-rooted perennial pastures on agricultural land is a long standing practice to assist in the control many forms of land degradation. These practices are widely recommended in catchment management plans as strategies to reduce the rise of groundwater tables and to reduce the rate of soil acidification. Perennial pasture resowing rates and top-dressing of perennial pastures were selected as indicators of the extent of adoption of sustainable pasture management practices.
