They provide a means of protecting significant areas of natural habitat, while still allowing land-uses such as grazing, mining and tourism to take place in accordance with strict guidelines laid down in a management plan. Chowilla Regional Reserve was proclaimed in 1993. The National Parks and Wildlife Act 1972 requires a report to be prepared for each Regional Reserve at intervals of no more than ten years and prescribes the assessment criteria to be used. This report for Chowilla Regional Reserve addresses the criteria required by the Act and provides recommendations on the future management of the land. The International Union for the Conservation of Nature (IUCN) recognises a multiple-use category of reserve which they have defined as ‘areas containing predominantly unmodified natural systems, managed to ensure long term protection and maintenance of biological diversity, while providing at the same time sustainable flow of natural products and services to meet community needs’. Regional Reserves conform to that definition. In economic terms, whilst some benefits of continued resource use on Chowilla Regional Reserve have accrued to the pastoral lessees, the contribution to the State’s economy has been minimal. The impacts on landscape and cultural features have been low to moderate and can be directly ascribed to the pastoral activities on the Reserve. At times, the impact on natural resources has been high due to the combined affects of pastoral production and large populations of kangaroos, feral and pest animals. There is room to improve the management of both the pastoral activities and total grazing management in the Reserve to achieve better environmental outcomes. The introduction of the Regional Reserve concept was an important step in a continuing process that has resulted in conservation becoming accepted as a legitimate consideration for natural resource management and utilisation over large areas of the arid-zone in South Australia. Regional Reserves provide an opportunity to learn and understand how best to integrate conservation and resource utilisation in an ecologically sustainable manner. The Review of Chowilla Regional Reserve indicates that there are still areas for improvement in this regard and offers a challenge for all involved. I look forward to a successful outcome for the sustainable management of this reserve in the future. In accordance with the provisions of Section 34A (5) of the National Parks and Wildlife Act 1972, I have much pleasure in presenting this report on the use and management of Chowilla Regional Reserve to Parliament.
