Pacific island nations are already experiencing the effects of a changing climate. Cyclones and severe flooding have hit Yap, Niue and Fiji recently. Air temperature, the number of cyclones and sea level are all predicted to rise, and changes in rainfall are also predicted across the Pacific (1). Forces driving climate change are beyond the control of island nations. Pacific islands, while constituting 0.12 per cent of the world’s population, release only 0.003 per cent of the world’s carbon dioxide from fuel combustion (2) .

This review was prepared by the Pacific Invasives Initiative (PII) on request from the Pacific Invasives Partnership (PIP). It was undertaken to examine the invasive species management components within the National Biodiversity Strategy and Action Plans of twelve Pacific island countries (PICs): Cook Islands, Fiji, Federated States of Micronesia, Kiribati, Marshall Islands, Niue, Palau, Papua New Guinea, Samoa, Solomon Islands, Tonga and Vanuatu.

The Cook Islands Ministry of Agriculture seeks approval for the release of the plan pathogen Puccinia xanthii Schw. (Pucciniales: Pucciniaceae) into Rarotonga for biological control (biocontrol) of the introduced plant cockleburr Xanthium pungens Wallr. (syn. Xanthium strumarium; Xanthium occidentale Bertol.) (Asterales: Asteraceae).

Invasive mammal eradications are a proven, effective method of restoring damaged ecosystems and preserving biodiversity. On most tropical oceanic islands indigenous land crabs compete with targeted alien species for bait and interfere with traps and detection devices. Current eradication practices are inherited from successful termperate or subantarctic campaigns, yet we do not possess trued and tried methods for managing land crab interference.

Biodiversity on marine islands is characterized by unique biogeographic. phylogenetic and functional characteristics. Island hold a disproportionate amount of the world's biodiversity, and they have also experienced a disproportionate loss of it.

A persistent problem in weed biocontrol is how to reliably predict whether a plant that supports development in laboratory host-specificity testing will be utilized in field conditions, and this is undoubtedly preventing releases of safe and effective agents.
