Invasive alien mammals are the major driver of biodiversity loss and ecosystem degradation on islands. Over the past three decades, invasive mammal eradication from islands has become one of society's most powerful tools for preventing extinction of insular endemics and restoring insular ecosystems. As practitioners tackle larger islands for restoration, three factors will heavily influence success and outcomes: the degree of local support, the ability to mitigate for non-target impacts, and the ability to eradicate non-native species more cost-effectively.

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

Barrow Island, north-west coast of Australia, is one of the world’s significant conservation areas, harboring marsupials that have become extinct or threatened on mainland Australia as well as a rich diversity of plants and animals, some endemic. Access to construct a Liquefied Natural Gas (LNG) plant, Australia’s largest infrastructure development, on the island was conditional on no non-indigenous species (NIS) becoming established. We developed a comprehensive biosecurity system to protect the island’s biodiversity.

The purpose of this report is to provide an overview of the various frameworks and initiatives that exist in the Pacific Island Countries and Territories (PICTs) with regards to invasive species management and how they could be utilised towards the development of a coordinated mechanism by the countries in the Melanesian region in addressing biosecurity and invasive species concerns. The terms of reference for this report can be seen in Annex 1.
