Pohnpei and their outer islands are very vulnerable to the introduction of Coconut Rhinoceros Beetle (CRB) because the CRB is present in Guam, Palau, Hawaii and South Pacific. Pohnpei is located near Guam, Palau and Hawaii and there is regular traffic by air and sea. For this reason it is very important that Pohnpei has a good Emergency Response Plan (ERP) in place not only for control/eradication but also for prevention and spread to other islands.

This paper examines how optimal prevention and control policies depend on the economic and biological characteristics of a randomly introduced biological invasion where the objective is to minimise the expected social costs from prevention, control, and invasion damages. The results characterise how optimal prevention and control policies vary with the initial invasion size, the invasion growth rate, and the probability distribution of introductions.

The Pacific islands have an extremely rich maritime heritage. The islands themselves were first populated by what are arguably the greatest mariners in human history. In pie-European times the Pacific islandersnavigated wooden canoes held together with coconut fibre across thousands of miles of open ocean, with
