The Mulga Land Biogeographic region represents a significant proportion of Australia's rangelandsand is a microcosm of the biodiversity and production related issues faced by rangeland managersworld wide.The Mulga Lands have undergone significant changes in relation to productivity andbiodiversity in the past 200 years. These ecosystems are serendipitous in nature, a phenomenon bestdescribed by state and transition models. Figure 1 diagrammatically represents the factors reported inthe literature as influencing system dynamics. This figure highlights that apart from social, economicand cultural factors, grazing pressure, climate (particularly rainfall) and woody shrub densities are themain drivers of historic vegetation change in the Mulga Lands. ...
