Using decision analysis to manage endangered species populations.

Published

Journal Article

The 1st example weighs the merits of managing a species as a single larger population or as 2 smaller populations in habitats vulnerable to catastrophic storms. Probability of extinction is used to measure species security. The 2nd example analyses whether to translocate animals among small, isolated subpopulations to avoid inbreeding depression. It demonstrates the assessment of trade- offs between population security and financial cost. The 3rd example considers the capture of individuals from a wild population for captive propagation. It shows how subjective preferences can be estimated for outcomes such as survival of a species only in captivity. It examines the management recommendations of disputing parties for consistency with their subjective beliefs and philosophical values. These examples show that decision analysis provides a framework for 1) integrating scientific information with concerns for financial costs and public opinion; 2) examining effects of uncertainty, subjective information and values on management decisions; and 3) facilitating communication among management agencies and public interest groups. -from Author
