This book features an investigation into the theory and means by which "value" can be placed on the environment and included in conservation decision making. In essence, the authors demonstrate a contingent valuation method which can be applied to environmental "goods," endangered species, and the conundrums of biodiversity. As an example, this methodology is applied to the conservation of endangered species in the State of Victoria, Australia, and discusses the use of such values in the decision making process required under the Victorian Flora and Fauna Guarantee Act.
