Info-graphic poster on the identified invasive species in the country
Four islands of the Aleipata group: Fanuatapu islet; Namua island, Nu’ulua, and Nu’utele.The aim of the surveys was to survey the status of IAS on these four islands with a special focus on rats, YCA, pigs and weeds, and with a focus on the two larger islands, Nu’utele and Nu’ulua.
The Palmerston rat eradication program ran from August-September 2023. NZ Department of Conservation's Emmanuel Oyston, field team leader of the eradication, sent weekly updates on their progress - their updates are available here.
A team from Manaaki Whenua Landcare Research travelled to Rarotonga during July/August 2023 to carry out monitoring of biocontrols released in previous years. The team used drones to conduct monitoring surveillance for the invasive African Tulip tree species, using LiDAR and other imagery techniques.
This newsletter also provides an update on the control of the biocontrols.
This dataset holds three reports on invasive species in Micronesia. . The objectives were three-fold: * To identify species on the islands that are presently causing problems * To identify species that, even though they are not presently a major problem, could spread to other islands where they are not present, potentially causing problems * To look for invasive species known to cause problems in ecosystems similar to the islands visited.
The Jungle myna (Acridotheres fuscus) was first recorded in Upolu in 1965, followed by the Common myna (Acridotheres tristis) in 1988 (Watling, 2001). It is believed they were introduced to control livestock ticks and unexpectedly became an invasive species; over the past two decades their populations have increased dramatically.
This document provides information regarding issues surrounding the myna: why mynas are a problem and what methods are currently been implemented to control and/or eradicate mynas from cities, islands, and countries.

Late is an isolated and uninhabited island located about 55 km WSW of the island of Vava’u, in the Kingdom of Tonga. The biological integrity of Late is threatened by invasive Pacific rats that were historically introduced to the island. This report assesses the feasibility of restoring Late through the removal of invasive rats, and describes options, recommendations, and challenges to realizing a successful project.
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.
Island ecosystems have proven to be particularly sensitive to
human disturbances (Bourne 1975; Byrne 1980; Jarvis 1979). This was first noted by Charles Darwin in the explanation of his theory of natural selection (Byrne 1980). Since then, qualities of insular species have been examined by various authors in an attempt to understand the basis for island vulnerability.

A Workshop on Regional Action to Combat Invasive Alien Species on Islands to Preserve Biodiversity and Adapt to Climate Change highlighted successes, deepened connections within regions and facilitated the exchange of experiences across regions.While discussions outlined significant obstacles to invasive alien species management2 on islands, they also showcased how targeted successes have led to major gains for conservation and development.Collaboration across developmental and environmental sectors and sustained support are critical to success in this field.Exciting new initiatives are dev
Ecosystem services are the benefits people obtain from ecosystems, such as clean air, fresh water, and the pollination of crops. The aim of this literature review was to find empirical data illustrating the ways in which conservation land and conservation management activities affect ecosystem services. The widely-held belief that natural ecosystemssuch as those found on conservation land in New Zealandprovide a range of ecosystem services is generally supported by the literature.
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.
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.
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.
