The plant, animal and fire factors are outlined which have contributed to changes in the biota, with specific examples taken from the chenopod shrublands, semi-arid woodlands and subalpine grasslands. Overall there has been a decrease in perennial herbs and an increase in annual herbaceous, inedible woody plants and soil erosion. Few plant species have been lost entirely, but there has been widespread local disappearance of mammals. A continuation of restoration is anticipated over the next 200 years. Pastoral activities will remain dominant and become established as a sustainable land use, with the further development of the conservation ethic among landholders, improved monitoring of vegetation change and further research into management. The development of joint management plans for sensitive areas and the completion of the reserves network are other avenues for improvement.
