The TGB Osborn Vegetation Reserve, Koonamore, was established in 1925 to record the changes in vegetation of a chenopod shrubland as the land recovered from severe stocking pressure. Permanent quadrats, photopoints and transects have recorded changes over 83 years to the present. Sheep were removed from the reserve, but rabbits, though initially suppressed, were not controlled for the first 50 years, and numbers were high in several periods. For the last 30 years continuous rabbit control has kept their numbers verylow. There have been large changes in the vegetation in response to the changes in grazing pressure, and also rainfall events. ...
