MULTIPLE LAND USE — AN ESSENTIAL PART OF ENVIRONMENTAL PLANNING

Abstract

The Australian petroleum industry has been involved in environmental planning and has developed an awareness of multiple land use over the past twentyfive years, more particularly over the past decade. This is in accord with the World Conservation Strategy and the National Conservation Strategy for Australia upon which the Australian State and Territory conservation strategies are based.

As the term implies, multiple land use means a sharing of the land. The range of uses includes reserves, heritage areas, agriculture, urban and suburban development and mining. To achieve multiple land use requires the restoration of the environment to its pre-development state as quickly as possible so that both uses can be maintained. This requires that the new user assess the impact of his development well before it begins. This assessment is normally achieved through an Environmental Impact Statement (EIS) or Environmental Review and Management Plan (ERMP). Most operators are familiar with these requirements.

This paper deals primarily with the restoration of the existing environment. Restoration is achieved by preserving, to the greatest extent possible, the vegetation and topsoil which are stripped from the development area. As little stockpiling as possible is done and the topsoil, mixed with the broken down vegetation, is returned as quickly as possible. In this way the contained seed load and nutrient values are not lost and regeneration results.

Apart from the practical aspects there is a need for the workforce involved to understand what they are conserving and why they are conserving it. A delicate balance exists in nature wherein the surviving plants and animals are able to cope with natural disasters. Management plans must include the principle that the collective impact of a new development will at no time exceed the impact of natural catastrophes.
