Quality and Uncertainty Assessment of Wildlife Habitat with Fuzzy Sets

Abstract

A method of assessing the quality of wildlife habitat based on the judgment of experts is proposed. The method uses the concepts of fuzzy sets and systems. The proposed method can be applied to describe the wildlife habitat in an area where planned project activities will affect vegetative patterns. It permits the evaluation of small parts as well as of the whole of a project area. This method can also generate other information required in preparing environmental impact statements. The proposed method can easily be programmed on computers. The main advantages of this method are that it provides for incorporating judgment uncertainty into the decision and has the ability to show the uncertainty in the final outcome, i.e., quality of wildlife habitat.
