In June/July 2002 an eradication programme to remove Pacific rats from Maninita Island in the Vava'u group of the Kingdom of Tonga was initiated. The techniques used were similar to those
used in successful rat eradications in New Zealand, in that Pestoff 20R pellets and a network of bait stations were used.
Conditions on the island were not what was expected, the forest having been adversely affected by cyclone Waka and subsequent defoliation by caterpillars, resulting in an open forest canopy. Rats were found to be present on the island in high numbers and were breeding.
Work is based around country visits by the network coordinator to support PILN teams to identify and take strategic action to manage their priority invasive species. The network is functioning by sharing awareness of successful activities being earned out by the teams, providing the mechanism for other teams to do the same, and actively encouraging them to do so.
Capacity building is linked to on-going invasive species projects and achieved through workshops and exchanges.

The Pacific Invasives Initiative (PII) is a sister partnership based at Auckland University which shares 6 partners with PILN. The goal of the PII is to contribute to conserving island biodiversity and enhancing the sustainability of island livelihoods by minimizing the spread and impacts of invasive species in the Pacific region. This is achieved by increasing support and developing capacity in the region for managing the impacts of these species.
For one of the species potentially at some risk of poisoning under the proposed rat eradication regime, the Friendly Ground Dove, Nuutele and Nuulua hold populations that are nationally significant. The complete loss of these populations would threaten the survival of the taxon in Samoa. Some authors consider the Samoan doves to be a separate race (Gallicolumba s. stairi) from those in Fiji and Tonga (Watling, 2001). Outside Samoa, the race is only found on the small island of Ofu,
1. During a recent survey around Upolu, Savaii and Nuutele the Yellow Crazy Ant was both observed and collected as samples in different locations.
2. The field survey reveals the extend distribution of the Yellow Crazy Ant through out Samoa.
3. 11 sites were visited in Savaii and 12 in Upolu and 1 in Nuutele; no survey was done on Nuulua due to weather conditions. On Upolu and Savaii the sites were located approximately 15km around the island.
One or two sites or stations fall inland.
The islands of Nu'utele and Nu'ulua have been identified as highly significant sites for conservation in Samoa. They hold large populations of species currently found nowhere else in the country' including threatened land-birds, seabirds and nesting
turtles. They also are the only offshore islands large enough and far enough offshore to be considered as refuges for several of the nation's species threatened on the larger islands by introduced mammalian pests. Such refuges have assumed greater
The restoration of the Islands of Nuutele and Nuulua is a priority of the Government of Samoa and the communities of Aleipata District. Planning is well advanced on a key element of this, the eradication of Pacific Rats (Rattus exulans) by aerial
spreading of toxic baits in mid-2006. The Friendly Ground Dove has been identified as a non-target species that may be at risk of taking the baits and one for which the Nuutele and Nuulua populations are significant. Several approaches for safeguarding
Since the early 1990s the Secretariat of the Pacific Regional Environment Programme (SPREP) has been promoting the use of environmental planning and assessment processes amongst its member countries and territories. SPREP's approach to environmental planning and assessment has been part of a global programme for improving environmental management and supporting sustainable development.
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.
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.

Pacific island countries are particularly vulnerable to the effects of invasive species. After habitat destruction or modification, invasive species are responsible for more species extinctions than any other cause. Further, the rate of extinction of native species has been higher oil islands than
anywhere else in the world. Invasive species have also degraded native ecosystems.

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.
This emphasizes that species recovery is conceptually different from extinction risk and reinforces the utility of the IUCN Green Status of Species to more fully understand species conservation status. Although extinction
Since Elton highlighted the problem of biological invasions, numerous studies have established their importance in the structural evolution of natural communities, in particular insular communities. Because of their isolation, islands are regarded as natural evolution laboratories which are characteristically very fragile once the boundary is disturbed. This fragility is illustrated by the high proportion of species extinctions observed in islands: since 1600, more than 75% of monitored disappearances have been registered in islands.

The extensive Pacific Islands region comprises around 30.000 islands scattered across the vast central Pacific Ocean. The island groups and sea areas are divided into 22 countries, with a total population of around 6 million people. The great majority of people live in relatively small and isolated coastal or rural village communities, and remain closely reliant on their local natural resources for subsistence and economic development.
Biodiversity conservation - that is, the conservation of plants and animals that make up the species richness of a country - is widely recognised as an issue of importance for the South Pacific as it is relevant to family livelihoods, culture and economic development as well as to the unique biological story that these islands possess. The biodiversity of the region is threatened by a broad range of causes including unsustainable logging and fishing, invasive species, pollution, soil erosion, fire, habitat conversion and agricultural run-off.
Ecosystem services are the benefits people obtain from ecosystems, such as clean air, fresh water, and the pollination of crops. The aim of this literature review was to find empirical data illustrating the ways in which conservation land and conservation management activities affect ecosystem services. The widely-held belief that natural ecosystemssuch as those found on conservation land in New Zealandprovide a range of ecosystem services is generally supported by the literature.
Life on Earth is disappearing fast and will continue to do so unless urgent action is taken. Well designed and effectively managed systems of protected areas are a vital tool for reducing biodiversity loss while delivering environmental goods and services that underpin sustainable development. There are currently over 130,000 protected areas worldwide, covering around 13.9 % of the Earths land surface and 5.9 % of the territorial marine surface. These areas represent a tremendous resource for conserving biodiversity and for protecting vital ecosystem services.
