A Pacific information brief from the Pacific Invasives Partnership (a working group of the Roundtable for Nature Conservation in the Pacific Islands)
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.
This study describes the biodiversity values of Malden Island, and assesses the potential benefits, feasibility and costs of removing key invasive species.
This NISSAP has been developed to identify invasive species and priority actions to address their threats on the environment, economy and livelihood of people.

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 Pacific region has benefited from a number of regional and national programmes to both assess the impacts of climate change on biodiversity and develop programmes to adapt to climate change. Such programmes are critical considering that the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) 1/ states that the Pacific region has already experienced temperature increases of as much as 1°C since 1910.
Climate change is a major threat to global biodiversity. From the tropics to the Poles, the worlds 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 Convention on Biological Diversity has been adopted by many countries, resulting in the development of national biodiversity strategies. This illustrates the international recognition of the importance of protecting ecosystems. However, ecosystems still face many threats, some of them growing and spreading so rapidly as to cause irreversible deterioration in many countries and areas.

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
Marine invasive species have received much less attention than terrestrial species worldwide. In the Pacific, the marine environment provides us with a significant part of our diet and income. Marine Managed Areas focus on protecting these important resources for livelihood purposes, biodiversity and ecosystem function, tourism and many other benefits. Although invasive species management is more difficult in the marine environment, it is not something we can neglect, and the efforts we put in need to increase. This guide seeks to provide some options for this management.
The biodiversity of the Solomon Islands, in general, is in good health. Low human population density, uninhabited islands, difficulties to access and use natural resources, and customary and legal protection, in various ways, can help explain this. Threats to the countrys biodiversity are mainly localized and vary across islands, biomes, ecosystems, corridors and taxonomy. In recent years habitat destruction and overexploitation of wildlife has had enormous pressure on all types of biomes.
Global biodiversity loss is disproportionately rapid on islands, where invasive species are a major driver of extinctions. To inform conservation planning aimed at preventing extinctions, we identify the distribution and biogeographic patterns of highly threatened terrestrial vertebrates (classified by the International Union for Conservation of Nature) and invasive vertebrates on ~465,000 islands worldwide by conducting a comprehensive literature review and interviews with more than 500 experts.
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.
