AbstractLand condition in northern Australia can be easily degraded by grazing or grazing in combination with drought. These areas require the use of grazing systems that allow persistence of native tussock grasses, and maintenance of soil condition. However, there is little information available on best level of utilization, or how plants and soils will respond to grazing and drought. This study examined effects of six different grazing regimes (based on timing and grazing intensity), applied over five (n=4) and 15 (n=2) years, on herbaceous vegetation (standing crop, basal area, size and spacing of grass tussocks) and soil properties (soil C, total N, total P, and soil-borne plant matter [roots and surface litter]) around grass tussocks in replicate (n=2) paddocks of eucalypt woodland in northern Queensland. Grass tussocks influenced soil C and total N at small (
