Abstract
This paper considers alternative approaches to the evaluation of Nature conservation resources as part of the overall process of establishing Nature conservation priorities. The techniques available for evaluation are seen to differ in their ideological base and methodology, and in the relative importance which they attach to physical and ecological features. This lack of consistency means that existing techniques only represent a partial basis for determining conservation priorities. Furthermore, the assumptions on which evaluation techniques are based tend not to be stated explicitly and often appear not to have been substantiated. These inconsistencies are due in part to ambiguity concerning the objectives of conservation, in part to the lack of research into the relationship between human demands and the features of Nature conservation resources, and in part to uncertainty as to the position of evaluation in the conservation priority-setting process. A model of this process for setting conservation priorities is presented. It delimits ecological evaluation as an objective, value-free element in the priority-setting process—where ecological evaluation is seen to provide information which aids decision-makers in the more value-laden socio-economic elements of conservation priority-setting. The model implies that the objective and subjective elements in existing evaluation techniques are not sufficiently explicit to ensure consistency in decision-making.
