Key words: biological diversity conservation tradeoff analysis, networks of protected areas


Much of modern nature conservation has been preoccupied with variations on the largely nineteenth century colonial notion of the national park. In this current period of tremendous rates of loss of habitat and biological resources, the pool of interventions available to the land use planner and manager must be expanded with underlying relationships and possibilities further explored. This paper outlines some of the tenets of the emerging theory of environmental planning for the conservation of biological diversity and considers the myriad of interventions available. Such measures are grouped into:

    1. protected area allocation;
    2. reserve management; and
    3. regulation of land use external to protected areas.

Three sets of tradeoffs emerge from the requirements for the maintenance of biological diversity in networks of protected habitats across districts and regions between:

    1. area of habitat protection and regulation;

    2. total area of protected habitat and relatively "natural" or intact condition of those ecosystems within reserve boundaries; and

    3. management within protected areas and regulation of land use outside of reserves.

Resulting conservation possibilities can vary between contexts. Alternative regimens of interventions for basic levels of biodiversity conservation reflect intrinsic biological and ecosystem constraints as well as more fluid historical, institutional and cultural factors. The highlighting of tradeoffs between habitat protection and expanded land use involves identification of threshholds that would support minimum levels of conservation of biological diversity. Identification of threshholds and constraints contributes to the development of more viable strategies for both conservation and economic development.
