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.

Situated between Fiji to the west and Samoa to the northeast, the Kingdom of Tonga (referred
to as Tonga) is comprised of 171 scattered islands of which less than 50 are inhabited. The islands are
mainly composed of limestone formed from uplifted coral. Current critical environmental concerns have
arisen due to deforestation; damage to coral reefs and the introduction and spread of invasive alien
species. Anthropogenic pressure has resulted in extensive modification of all ecosystems on the

On 20 November 2006 the Biological Diversity Advisory Committee (BDAC), whose role it was to advise the then Australian Government Minister for the Environment and Heritage, held a one day workshop in Canberra on climate change and invasive species’ impacts on biodiversity. Eight talks were given, followed by a session of free discussion. Most attendees were experts from government departments, universities, the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and cooperative research centres (CRCs).

This report examines the role of the ecosystem services in reducing the vulnerability of the people of the Pacific Islands to climate change. Specifically, it describes the decision-making frameworks and the current state of knowledge of specific ecosystem-service/development relationships that are relevant to EbA.

Natural disasters such as hurricanes, cyclones, and tropical depressions cause average annual direct losses of US$284 million in the Pacific. With a combined population of fewer than 10 million people, annual losses are the highest in the world on a per-capita basis. Extreme weather events such as heavy rainfall are closely linked to climate change, suggesting that Pacific Island nations face increasing risk of disasters such as flooding and landslides. Proactive management through infrastructure development, social solutions, and/or ecosystem-based adaptation can mitigate these risks.

The “Invasive Species Battler” series has been developed to share what we have learned about common invasive species issues in the region. They are not intended to cover each issue in depth but to provide information and case-studies that can assist you to make a decision about what to do next or where to go for further information.

Climate change is expected to cause extinctions when native plants and animals are prevented from migrating out of their hotter or drier habitats to more suitable climates. But for many species a more

Climate change is a major threat to global biodiversity. From the tropics to the Poles, the world’s ecosystems are all under pressure. A study published in the scientific journal Nature posited that 15 to 37% of terrestrial animal and plant species could be at risk of extinction because of human-induced impacts on climate (Thomas et al., 2004). Scattered across the four corners of the Earth, European Union overseas entities, are home to a biological diversity that is as rich as it is vulnerable.

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.

Fondee en 1948, l’Union internationale pour la conservation de la nature rassemble des Etats, des organismes gouvernementaux et un large eventail d’organisations non gouvernementales au sein d’une alliance unique : plus de 1000 membres dans 147 pays. L’UICN regroupe egalement un reseau de plus de 10 000 experts benevoles qui apportent leurs connaissances a travers six commissions specialisees. Le secretariat de l’UICN est compose d’un siege mondial en Suisse et de 62 bureaux regionaux et nationaux.

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

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.

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.
