Following the incursion of rats (Rattus rattus) on Taukihepa (Big South Cape Island; 93.9 km²) off southern New Zealand in 1963, and the subsequent extirpation of several endemic species, the New Zealand Wildlife Service realised that, contrary to general belief at the time, introduced predators do not reach a natural balance with native species and that a safe breeding habitat for an increasing number of at risk species was urgently needed.
Rat eradication is a highly effective tool for conserving biodiversity, but one that requires considerable planning eff ort, a high level of precision during implementation and carries no guarantee of success. Overall, rates of success are generally high but lower for tropical islands where most biodiversity is at risk. We completed a qualitative comparative review on four successful and four unsuccessful tropical rat eradication projects to better understand the factors influencing the success of tropical rat eradications and shed light on how the risk of future failures can be minimised.
The Key Biodiversity Areas and Important Bird Areas (KBA's
& IBA's) approach is a simple, effective means of
implementing the protected areas elements of the Convention of Biological Diversity (CBD). KBAs and IBAs are places of
international importance for the conservation of biological diversity through protected areas and other governance mechanisms.

To date, there is no defined list of priority migratory species of concern (indicator species) at the regional level for the Pacific islands to direct efforts. The Regional Marine Species Action Plans (under revision; see below) and the regional CMS Memorandum of Understanding (2006) for cetaceans can be considered as part of regional level prioritisation. For birds, Bird Life’s Data zone includes a list of migratory species for each country in the region.
