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.
PNG is endowed with rich natural resources and culture and is known as one of the cultural and mega biodiversity hotspots globally. Located on the eastern part of the island of New Guinea, PNG contains roughly 1 percent of the global landmass, with four major islands and over 600 islands and atolls. PNG also has one of the diverse reef system in the world and has a total of 3.12 square kilometers of economic exclusive zone (EEZ) of marine territory. Over 840 spoken languages exist and spoken by over 1000 different tribes.
It is desirable that all citizens of Papua New Guinea (PNG), wherever they live, have access to potable water and an appropriate standard of sewerage collection and treatment. Unfortunately, PNG‘s rugged geography makes that difficult, if not impossible, to achieve. Most of PNG‘s people live in rural areas (with over 85% of the population depending on semi-subsistence agriculture) and lack access to safe drinking water or sanitation. Apart from the cities of Port Moresby and Lae, urban areas are mostly small towns with fewer than 1,000 households.

This dataset contains all spatial data that is related to the Tonga volcanic eruption. Maps produced are derived from credible data source such as UNOSTAT and UNITAR.
The WASH Baseline Survey is an initiative of the Water and Sanitation Sector which aims to:
1. Gain a better understanding of the water and sanitation situation nationally; and
2. Collect information about Knowledge, Attitude and Practices of the population regarding water use, sanitation status and hygiene behaviour.
Cyclone Evan hit Samoa in December 2012 and caused immense damage and significant losses. This comprehensive assessment estimates those damages and losses, and identifies the needs of the affected population.
In this report, the value of durable physical assets across all economic and social sectors destroyed by Evan (referred to as damage) is estimated at SAT 235.7 million, equivalent to US$103.3 million.
Solomon Islands is composed of almost 1000 islands and has the second longest coastline and the second largest Exclusive Economic Zone (EEZ) in the Pacific. These physical characteristics and the unique society and culture of the population are the basis of the fundamental relationship that Solomon Islanders have with the ocean. The Marine Atlas for the Solomon Islands compiles over a hundred datasets from countless data providers and for the first time makes marine and coastal information accessible and usable as data layers and as raw data.
The Tonga State of the Environment 2018 report has been developed to answer three key questions related
to the environment of Tonga, and is based on seven thematic areas:
• What is the current condition of the Tongan environment?
• What are the risks the Tongan environment faces and what measures have been put forward to minimise them? This could provide lessons for Tonga.
• Where is the environment of Tonga headed based on the assessed thematic areas?

This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey.
The dataset is included the Digital Atlas of Micronesia, module Pohnpei, by Island Research & Education Initiative (iREi), in collaboration with Water and Environmental Research Institute of the Western Pacific (WERI) University of Guam and partial funding from United States Geological Survey (USGS), under WRRI 104-B Program, project # 2016GU302B.
This dataset the extent of coral reefs around Pohnpei. The data layer shown here is a subset of Pohnpei base layer. The original data, so-called Digital Line Graphs (DLSs), were created by U.S. Geological Survey (USGS) for the 1:25,000-scale topographic maps (2001). The shoreline was modified by by University of Guam (UOG) (2017) based on 2016 Worldview-3 satellite imagery from Digital Globe. The dataset was slightly shifted and also updated (mainly around Kolonia and its vicinity).
