Bunny ByrD Each station report suggests a recommended Challenge carrying capacity over summer (November to April) Channel for range condition as seen at the time of survey. This Cole Flood figure is calculated on a land system by land system Frederick basis by determining from traverse data, the Horsehoe proportion of vegetation in good, fair and poor Jimba condition and applying stocking rates (see Table 1.2) Liver to each condition level. Millex Mongolia The actual stocking rates suggested in Table 1.2 are Outcamp Sandiman derived as much as possible from empirical data on Sherwood vegetation and animal production, obtained during Tindalarra long-term grazing trials (e.g. Watson and Holm 1990, Trillbar Holm 1991), which have been conducted in the region Violet and elsewhere in the arid shrublands of Western Wiluna Yanganoo Australia. For poorer pastoral potential classes of land systems, for which there is no experimental evidence, 353 T we have drawn on experience from leases on which Table 1.2. Recommended over summer grazing management has evidently achieved long­ carrying capacities for land systems of each term resource conservation, as indicated through class of pastoral potential, at three levels of range monitoring and records of animal productivity vegetation condition (e.g. Morrissey and O'Connor 1988).
