This project addresses the problem of the absence of a comprehensive pest risk management system that combines economic and scientific analyses into a single decisionmaking framework As such the main objective of this project is to develop a comprehensive framework and modeling system, integrating the biological profile of a pest species with economic information, to evaluate potential damages from pest invasion and the impact of alternative management decisions. A key output of the project is the development of userfriendly pest risk software that will integrate the information required of pest risk assessment into a standardized tool that can be used by policy makers/operational managers. Among other things, the software offers guidance over choice of key management options, especially those that require significant private participation.
