Thomas, Peter.

2017
Invasive alien species represent an insidious and pervasive threat to the environmental, economic and human well-being of the Pacific islands. Pacific island ecosystems make up one of the world’s important biodiversity hotspots, with high numbers of endemic species that are particularly vulnerable to extinction due to their limited habitat and isolation.|This book is intended to serve as a practical guide, calling attention to the need to link emergencies, disasters and development, not only in policy statements, but in practical ways. The book identifies physical and social factors and processes determining disaster vulnerability and offers the reader a range of vulnerability-reduction options in development and disaster mitigation. The book covers the main relief and response technologies for a range of natural and technological disasters, and deals with community participation, health education, training and other social aspects relevant to the protection of health and the environment in emergencies and disasters.|The UNEP/GEF Prevention, Control and Management of Invasive Alien Species in the Pacific Islands project also known as the IAS project, commenced on 12 September 2012 and was due for completion on 30 September 2016, following an extension of one year. The project was designed to provide support to Pacific Island countries in their national efforts to implement the Guidelines for Invasive Species Management in the Pacific – a Pacific Strategy for managing pest, weeds and other invasive species (Tye 2009) which were developed and adopted as the regional strategic framework for invasive species management in 2009. Ten Pacific Island countries originally participated in the IAS project, these being the Cook Islands, Federated States of Micronesia, Kiribati, Marshall Islands, Niue, Palau, Papua New Guinea, Samoa, Tonga and Vanuatu. These were reduced to nine countries with the withdrawal of Papua New Guinea following the Mid-Term Review due to issues related to the country’s readiness to engage with the project. The project was therefore, responsible for delivering of support to a culturally, geographically and economic diverse set of Small Island Developing States (SIDS) spread across the vast geographical scope of the Pacific Ocean. The project was implemented by the UN Environment as the Implementing Agency (IA) and Executed by the Secretariat of the Pacific Regional Environment Programme (SPREP) as the Executing Agency (EA). In-country sub projects and activities were facilitated by National Project Coordinators and overseen by national Invasive Species Coordinating Committees. Its goal "to conserve ecosystems, species and genetic diversity in the Pacific region" is broad and aspirational and is backed by the Objective "to reduce the environmental economic and human health impacts of invasive alien species in both terrestrial and marine habitats in the Pacific region". The Project consisted of 5 core components: Building foundations for sustainable Invasive Alien Species (IAS) management by generating awareness and support, building institution and human capacity and strengthening legislation, policy and protocols. Defining problems, prioritisation and decision making by improving baseline information on IAS distribution and status, establishing systems to assess risk and prioritise action and developing or utilising effective management techniques. Taking management action through improved bio-security and border protection, direct management action through eradication and application of best practice methods and restoring ecosystems after IAS management. Undertaking effective monitoring and evaluation of the project.| Establishing effective and efficient project management and governance. This Terminal Project Evaluation is undertaken by the Evaluation Office of the UN Environment in order to assess the effectiveness of the project and its likely future impact on the state of IAS management in the region and its likely impact on invasive species and the environmental health of the participating countries. Further, the report aims to discern lessons and offers recommendations which may help improve the development and implementation of similar multi-country projects in the future both in the Pacific region and globally.

2008
The eradication of the seven remaining animal pest species remaining on Rangitoto and Motutapu was announced by the Prime Minister and Minister of Conservation in June 2006. With stoats, cats, hedgehogs, rabbits, mice and two species of rats spread across an area of 3842ha, the proposed project is the most challenging and complex island pest eradication the Department of Conservation (DOC) has ever attempted. To better understand the scale and complexity of the project, a feasibility study was undertaken. This study considered the ecological, economic and social context of the project to allow an informed decision to be made on whether or not to commit resources to further eradication planning. This document outlines the findings of the feasibility study and concludes that while a number of contingencies exist within the project, the proposed eradication is not only feasible, but has many significant benefits. No single precedent exists on which this project can be modelled and information from a wide range of sources has been required. Previous eradication and control programmes have been reviewed in conjunction with what is known about the behaviour and biology of the target species. In some cases, where information has not been available and could not be inferred, trials have been undertaken. The document has been reviewed by a number of experts both within New Zealand and overseas including DOC’s Island Eradication Advisory Group. Consultation has also been undertaken with all of the islands’ key stakeholders and communities of interest. Comments from all of these parties have been reflected in the report. Rangitoto is an iconic Scenic Reserve located just 9km from downtown Auckland City. The island is internationally significant both for its ecology and geology and is an extremely popular visitor destination served by regular ferry services. Motutapu, a Recreation Reserve, is connected to and positioned immediately to the east of Rangitoto. The island, currently managed as a pastoral farm, is noted for its extensive archaeological record but retains a diverse range of habitat types and is the focus of a community-led restoration programme. In addressing the question, ‘can it be done?’ particular attention has been paid to mice, ship rats, hedgehogs and rabbits as eradication of these species on the scale of Rangitoto and Motutapu has never been attempted. Preventing reinvasion on such highly accessible and intensively visited islands is also an enormous undertaking. It is accepted, that of all the target species, mice present the greatest risk of failure. However, while a number of mouse eradications around the world have failed, all ten attempts on islands beyond the swimming range of mice that have followed current Departmental best practice have been successful, providing confidence in the method. Rangitoto and Motutapu are a significant step up from previous operations in terms of scale but are also the logical next step to apply current techniques. Despite the unprecedented elements within the project, it is considered that the key dependencies on which eradication success relies can be met for the species targeted. Preventing reinvasion is perhaps the most important consideration of the feasibility study and the one that will ultimately determine the fate of the project. Achieving an adequate level of protection for the islands hinges heavily on changing the behaviour of all 100,000 visitors that arrive on an annual basis. Without this any investments made in removing pests will be wasted. Bringing these changes about appears possible but is contingent on a number of commitments and actions that must be put in place by both DOC and its key partners. The feasibility study also addresses what the project will take to complete and attempts to identify as many of the planning issues as possible to enable the project to be properly sized. It explores the techniques that must be used, the resources that will be required and the timeframe over which they need to be deployed. While this eradication project is the most challenging and complex to be undertaken by DOC, it also presents a significant opportunity to improve our current understanding of eradication theory and practice. If successful, the project offers outstanding benefits for conservation. The recovery of locally and nationally endangered species, the creation of a stepping stone for wildlife movement between the Hauraki Gulf and the Auckland isthmus, the potential for advocacy and education, and increased recreation and economic opportunities are just some of the likely gains. The study has shown that this project is feasible, but also that there are many significant reasons why it should proceed.

Le chat haret est l’un des prédateurs invasifs les plus dommageables pour la biodiversité insulaire. Sa présence est associée à une perte de biodiversité sur l’ensemble des îles sur lesquelles il est établi, et où il constitue une menace pour de nombreuses espèces de vertébrés souvent endémiques et menacés. En Nouvelle-Calédoniedes populations de chats harets sont présentes dans tous les milieux et habitats et l’étude de son écologie et de ses impacts sur la faune ont fait l’objet de ce travail de thèse. L’analyse du régime alimentaire sur 14 sites d’études représentatifs des 4 habitats majeurs a révélé un régime très diversifié et une forte prédation sur les vertébrés natifs et notamment sur le groupe des scinques, des roussettes et des pétrels. Parmi les 44 espèces de vertébrés retrouvées dans le régime alimentaire de ce prédateur invasif, la plupart sont endémiques et 20 sont listées comme menacées sur la liste rouge mondiale de l’UICN. Le suivi des déplacements d’une dizaine d’individus équipés de colliers GPS au niveau d’une presqu’île de la côte ouest abritant une importante colonie d’oiseaux marins, a permis de mettre en évidence de grands domaines vitaux pour les mâles, des domaines vitaux petits pour les femelles et des patrons de déplacements importants liés aux différentes étapes du cycle reproducteur des oiseaux marins. Ces éléments, couplés aux analyses de régime alimentaire suggèrent une prédation à la fois sur les adultes reproducteurs mais également sur les jeunes oiseaux proches de l’envol, et ceci à une large échelle géographique puisque certains des chats harets concernés avaient le coeur de leur domaine vital situé à plus de 3km de la colonie. Une opération expérimentale de contrôle d’une population de chats harets a été conduite sur cette presqu’île et a montré une faible durabilité des effets de la suppression des individus sur les densités observées et une rapide recolonisation du site. Les résultats de ce travail plaident pour la mise en place de mesures de limitation des impacts occasionnés et permettent en particulier de cibler les habitats de maquis et forêt humide comme prioritaires en matière de limitation des abondances. Ces travaux nous éclairent également sur l’emprise spatiale et l’intensité des futures mesures de contrôle à conduire dans le contexte d’îles de grande superficie et fortement envahies.
