Abstract Global changes, from habitat loss and invasive species to anthropogenic climate change, have initiated the sixth great mass extinction event in Earth's history. As species become threatened and vanish, so too do the broader ecosystems and myriad benefits to human well-being that depend upon biodiversity. Bringing an end to global biodiversity loss requires that limited available resources be guided to those regions that need it most. The biodiversity hotspots do this based on the conservation planning principles of irreplaceability and vulnerability.
Williamson and Sabath (1982) have demonstrated a significant relationship between modern population size and environment by examining atoll area and rainfall in the Marshall Islands. The present work seeks to extend that argument into prehistory by examining the relationship of ancient habitation sites and size of aroid pit agricultural systems to atoll land area and rainfall regime along the 1,500-3,500 mm precipitation gradient in the Marshall Islands.
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.

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.
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 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
The need for a Pacific Biodiversity Information Forum to provide a venue and support for biodiversity information needs in the Pacific Basin was established during the GBIF (Global Biodiversity Information Facility) meeting on Maui in May of 2002. Interested parties met again during the October 2003 GBIF meeting in Tsukuba, Japan and reaffirmed the need and began to draw up a governing structure for PBIF and identify specific biodiversity needs in the Pacific Basin that can be addressed through projects.

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 aim of this consultancy is to prepare a broad analysis of legal and institutional options for the establishment and management of Conservation Areas in fourteen independent Pacific Island countries. The full terms of reference for the consultancy are annexed at Appendix 1.

The botany of four small, relatively undisturbed tuff cone islands off the east coast of Upolu, Western Samoa, is examined. During a series of visits to the islands, the vegetation was studied in nine sample plots, and a checklist of the 260 species comprising the flora was compiled. Six types of native vegetation are recognized, one of which (Diospyros coastal forest) appears to be unique to tuff cone islands. Casual observations were made on the avifauna and turtle
species, and the ecological significance of the islands is discussed.
Since 1987, I have assisted the Cook Islands Conservation/Environment Service and, more recently, the Takitumu Conservation Area Project and the Avifauna Conservation Programme of the South Pacific Regional Environment Programme (SPREP) to plan and implement a recovery programme for the kakerori, a critically endangered forest bird endemic to Rarotonga. In 1989, the kakerori was one of the 10 rarest birds in the world, and classified as 'critically endangered' (Collar et al. 1994) with a population of just 29 birds. I calculated
