The world is facing a biodiversity crisis. Nowhere is that more apparent than on oceanic islands where invasive species are a major threat for island biodiversity. Rats are one of the most detrimental of these and have been the target of numerous eradication programmes; a well-established conservation tool for island systems.
The impacts of house mice (Mus musculus), one of four invasive rodent species in New Zealand, are only clearly revealed on islands and fenced sanctuaries without rats and other invasive predators which suppress mouse populations, influence their behaviour, and confound their impacts. When the sole invasive mammal on islands, mice can reach high densities and influence ecosystems in similar ways to rats.
Following the incursion of rats (Rattus rattus) on Taukihepa (Big South Cape Island; 93.9 km²) off southern New Zealand in 1963, and the subsequent extirpation of several endemic species, the New Zealand Wildlife Service realised that, contrary to general belief at the time, introduced predators do not reach a natural balance with native species and that a safe breeding habitat for an increasing number of at risk species was urgently needed.
Rat eradication is a highly effective tool for conserving biodiversity, but one that requires considerable planning eff ort, a high level of precision during implementation and carries no guarantee of success. Overall, rates of success are generally high but lower for tropical islands where most biodiversity is at risk. We completed a qualitative comparative review on four successful and four unsuccessful tropical rat eradication projects to better understand the factors influencing the success of tropical rat eradications and shed light on how the risk of future failures can be minimised.
The Baja California Pacifc Islands, Mexico, are globally important breeding sites for 22 seabird species and subspecies. In the past, several populations were extirpated or reduced due to invasive mammals, human disturbance, and contaminants. Over the past two decades, we have removed invasive predators and, for the last decade, we have been implementing a Seabird Restoration Programme on eight groups of islands: Coronado, Todos Santos, San Martín, San Jerónimo, San Benito, Natividad, San Roque, and Asunción.
Considerable bene?ts can be achieved for indigenous biodiversity when invasive vertebrates are removed from islands. In New Zealand, two logistically challenging eradications were undertaken, one to remove cats (Felis catus) and the other Paci?c rats (Rattus exulans) from Te Hauturu-o-Toi/Little Barrier Island (Hauturu). Here we document the short- and long-term impacts of these interventions on the biodiversity of Hauturu. We also assess the extent to which predicted outcomes were re?ected in the measured responses for a wide range of species.

The main objective of the expedition was to compare as large a series of islands of different climatic conditions, ages and geological origins as possible. This necessitated short visits to each selected island. The structure and components of the ecosystem under study were the focus of attention, while their functioning was considered to be of secondary importance.

In September 1991 the Government of the Marshall Islands requested assistance in compiling a bibliography of material relating to fisheries and marine resources of the Marshall Islands. After discussions between the staff of the Marshall Islands Marine Resources Authority and the Fisheries Programme of the South Pacific Commission, it was decided that a search for appropriate documents would take place in Majuro, Guam, Tokyo, Honolulu and Suva during September, October and November 1991.

Assessments of the general condition, stocking, composition, and growth of mangroves on the islands of Pohnpei and Yap and at one area on Kosrae were undertaken at the request of these states. Methods used included: reconnaissance on foot, by air and by boat; use of 1976 aerial photographs; remeasurement of forest inventory plots installed by the US Forest Service in 1983; and installation of new inventory plots, examination of public records, and reviews of published data (Pohnpei).
The Regional Seas Programme was initiated by the United Nations Environment Programme (UNEP) in 1974 in response to the selection of the oceans as a priority area by the UNEP Governing Council. It is a global programme implemented through regional
components under the guidance of the Oceans and Coastal Areas Programme Activity Centre at UNEP headquarters in Nairobi.
Each regional action plan is formulated by the Governments concerned to respond to the needs of the region for a comprehensive approach to controlling both the consequences
The tropical seas are liberally sprinkled with coral islands.
Many of them are associated with continents and large continental islands, in relatively shallow water, rising from continental shelves. Many, also, are in deep water - atolls, barrier reef islets round high islands, almost atolls', tops of drowned karsts, and a few moderately elevated atolls. These last are among the most fascinating of all, scientifically.

Pesticides as covered in the project include acaricides,
biological pesticides (bacteria, viruses), defoliants,
dessicants, fumigants, fungicides, herbicides, insecticides,
molluscicides, nematicides, rodenticides and synergists.
Pesticides included are those used in plant protection, in
animal health (products for external use only), in human
health programmes and for urban pest control.
There is a high level of uncertainty with the specific estimation of pollutant loads. A large body of work has
been completed that provided qualitative and quantitative data; however, the noting of data gaps and inherent uncertainties of the methods used have qualified much of the quantitative data. Much of the data are based on rapid assessment methods that utilise generic loading rates, assumed waste flow composition, typical production methods, local production rates. Unfortunately, production rate data are inconsistently available and are difficult to verify.
Recognising the problems of information management and the use of data as a resource many countries of the SPC region have expressed the desire for some form of integrated network to handle information and data relating to the resources and
environment of the Region. Accordingly SPREP commissioned this review of the current situaiton with regard to handling, storage and evaluation of such data in the countries of the region.

Multilateral Environmental Agreements (MEAs) are a subset of the universe of international agreements. What distinguishes them from other agreements is their focus on environmental issues, their creation of binding international law, and their inclusion of multiple countries. Over the years, many MEAs have been negotiated and agreed at the international and regional levels. Some have a few Parties; some have almost global participation.
This report presents the results of a twelve day survey expedition (5 to 16 December, 2004) and represents the first ever systematic effort to document the marine biodiversity of the Great Sea Reef (GSR), locally known as Cakaulevu, to the north of Vanua Levu in the Fiji Archipelago. 23 sites were surveyed over 6 major habitat types: outer barrier reefs, back barrier reefs, channels, mangrove island fringing reefs, rocky island fringing reef and submerged patch reefs.

The Pacific islands are uniquely vulnerable to a variety of unpredictable events - natural disasters, including potential climate change impact, as well as health emergencies. The region is made up of mainly very small countries with poor socio-economic development. These and other contextual factors result in unique challenges in building systems, skills and experience necessary to maintain and promote a well functioning national society.
