Henderson island, a World Heritage Site in the Pitcairn group, south-central Pacific Ocean, has often been thought to have a pristine vegetation. Our archaeological investigations and field observations in 1991-1992, supported by recent observations in
1997, suggest the occurrence of former areas of Polynesian cultivation near to the North and East Beaches, and indicate that about 17 non-native vascular plant taxa have occurred.
The study of dispersal processes of small mammals, and especially of rodents, has a wide range of applications and until recent years there were few publications discussing the
colonisation of 'oceanic' islands by small mammals (cf. Crowell, 1986; Diamond, 1987; Hanski, 1986;Heany, 1986; Lomolino, 1986).
The Tokelau Islands consist of three atolls (Atafu, Nukunonu and Fakaofo) approximately 500 km north of Western Samoa. Their numerous islets are formed mainly of coral sand and rubble with no standing freshwater. Sixty-one plant species have been recorded, 13 of these being introduced and 10 being adventives. There are three vegetation zones, the beach, the beach-crest, and the interior coconut/fern zone with the physiognomy of a humid tropical forest. Marine invertebrates have not been studied.

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.

The Kingdom of Tonga requested assistance from the US Department of Agriculture. Forest Service,Institute of Pacific Islands Forestry, to conduct a survey of invasive plant species of
environmental concern, similar to surveys previously conducted in Micronesia. American Samoa and Niue. The survey was carried out from 5-20 July 2001. The islands of Tongatapu. Eua,
A Workshop on Regional Action to Combat Invasive Alien Species on Islands to Preserve Biodiversity and Adapt to Climate Change highlighted successes, deepened connections within regions and facilitated the exchange of experiences across regions.While discussions outlined significant obstacles to invasive alien species management2 on islands, they also showcased how targeted successes have led to major gains for conservation and development.Collaboration across developmental and environmental sectors and sustained support are critical to success in this field.Exciting new initiatives are dev
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.
