Problem Definition-Baseline

Common mynas have been introduced (often as biocontrol for insects) or colonised many islands in the Pacific. They are one cause of decline in some native bird species such as endemic kingfishers, and are a pest when they damage fruit and compete for food to put out for domestic animals.

Although it is now widely acknowledged that economic analysis and the use of economic instruments are key to dealing with the problems associated with biological invasions, there remains little guidance as to how economic approaches and tools should be applied in practice. Invasive species have many unique and unusual characteristics which set them apart from other environmental and land use issues, meaning that analysis does not lend itself easily to conventional economic models.

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 Prevention and Management of Invasive Species: Forging Cooperation throughout the Austral Pacific

Invasive alien species (IAS) threaten human livelihoods and biodiversity globally. Increasing globalization facilitates IAS arrival, and environmental changes, including climate change, facilitate IAS establishment. Here we provide the first global, spatial analysis of the terrestrial threat from IAS in light of twenty-first century globalization and environmental change, and evaluate national capacities to prevent and manage species invasions. We find that one-sixth of the global land surface is highly vulnerable to invasion, including substantial areas in
