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.

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?
The Dataset contains and will contain the following: • Updated text; • National R2R website or associated links; • Social media account names/handles – FB, Twitter, Instagram, Youtube etc; • Newsletters ; • Articles ; • Videos • Photographs • Resources – Concept/Technical Notes, Guides, Posters etc.
This is for R2R consultancy announcement

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.
The Economics of Fisheries and Aquaculture in the Coral Triangle (EFACT) is the first report of its kind that consolidates primary and secondary information on fisheries and aquaculture using a regional lens and analytical tools from economics. The EFACT is an output of the Asian Development Bank (ADB) technical assistance—Regional Cooperation on Knowledge Management, Policy, and Institutional Support to the Coral
Triangle Initiative (CTI).
