Rattus rattus, or black rats, are rampaging through Tuvalu's atolls and gnawing through the country's chief export crop - coconuts.

The Little Fire Ant may be small but it has a very long scientific name - Wasmannia auropunctata. It is about 1.5 mm with a light to golden brown colour. Its home is Central and South America but it has travelled far to the Pacific islands and now lives in eight of our island countries - French Polynesia, Guam, Hawaii, New Caledonia, Papua New Guinea, Solomon Islands, Vanuatu and Wallis and Futuna.

The Pacific is biologically unique, as its isolated islands provide ideal conditions for the evolution of new species. Thus, Pacific islands have high numbers of "endemic"species - species that are restricted to only one or a few islands and found nowhere else in the world.

Invasive alien species represent an insidious and pervasive threat to the environmental, economic and human well-being of the Pacific islands. Pacific island ecosystems make up one of the world’s important biodiversity hotspots, with high numbers of endemic species that are particularly vulnerable to extinction due to their limited habitat and isolation.

The aim of this toolkit is to provide a clear, user-friendly guide to the application of economic approaches and tools to invasive species. It addresses the issues associated with identifying the factors which cause the spread of invasives, incorporating consideration of invasive species into economic planning and

It may be possible to tell that a species is likely to be invasive, for example because it has been a problem elsewhere. However it will be difficult to say with certainty that a
