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.
Invasive species, particularly animals, are being eradicated from islands at ever more ambitious scales. In order to protect island biodiversity and the essential ecosystem functions that it provides, however, plant invasions should be given more management attention. While many advances have been made, plant eradication is inherently more difficult than animal eradication due to persistent seed banks, and eradication may not be possible for more extensive populations.
How do introduced species cause problems for biodiversity? What makes a species invasive? When humans introduce non-native species to a new environment, it can have disastrous impacts on native species and the entire ecosystem.

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.

Invasive species are the primary cause of extinction on islands (IUCN Red List 2020, SPREP 2016, SOCO 2017). Invasive species have been formally identified as a threat for 1,531 species in the Pacific islands region to date (IUCN Red List, 2020). Pacific leaders have established two core regional indicators for invasive species management. Efforts for invasive management are ongoing in almost all Pacific island countries and territories.

The Cook Islands signed the Convention on Biological Diversity at the Earth
Summit in 1992. As a Party to the Convention, the Cook Islands Government
committed itself and its people to conserve its biodiversity, to use it in a sustainable manner, and to share its benefits in an equitable manner. It also committed itself to control invasive species (the weeds and pest animals in natural ecosystems and agricultural systems), and to reduce the likelihood of future invasions.

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
nothing but the stars and their intimate knowledge of the sea to aid navigation. Today, this seafaring tradition is continued, with several island countries, such as Kiribati and Tuvalu, being suppliers of seamento the regional and global shipping fleet.
SPREP's direction in the Islands Ecosystems Programme reflects a
fundamental commitment to sustaining the livelihoods of island peoples today and tomorrow by supporting ecosystem management and species conservation. The Programme focuses on developing the capacities of the peoples of the Pacific islands to equip them to sustainable manage and conserve the terrestrial, coastal and marine ecosystems of their islands. The programme also focuses efforts to protect priority threatened species, and to protect Pacific island countries and terrttories (PICTs) from
On 6 January 2004. cyclone Heta devastated much of the South Pacific island nation of Niue. Extensive damage was done to forest, particularly of the north- western sector, with many trees up-rooted and others stripped of branches and foliage. This report details our findings from a survey of Niue's birds and rodents during 3-19 September 2004 and compares these with results from a similar survey in September 1994.
American Samoa is a group of oceanic islands, which lie about 3,680 km southwest of Hawaiíi and about 2,560 km from the northern tip of New Zealand. It is situated along 14 degrees latitude south of the equator. Its immediate neighbor is Samoa (formerly known as Western Samoa), an independent state 128 km to the west. The total land area of American Samoa is about 200 square kilometers, which is shared by five main islands, namely Tutuila, Tau, Ofu, Olosega, and Aunuu.
The biodiversity of the Pacific region is recognised as being globally significant. The Solomon Islands was recently included into the famous "Coral Triangle", the area of ocean considered to have the highest marine biodiversity in the world. This includes the waters of the Philippines, Indonesia and Papua New Guinea. The Solomon Islands Rainforest Ecoregion is recognised as "one of the world's great Centres of Plant Diversity"
The purpose of the National Invasive Species Strategy is to minimize the harmful effects of invasive species on the environment and society of Palau through coordination of efforts at all levels of Palauan society, and to facilitate cooperation with neighboring countries and the Pacific Islands region to prevent the movement of invasive species.
