Afin de protéger la biodiversité terrestre et marine et de préserver les conditions de vie de la population Wallisienne, il est proposé d’enlever les vertébrés envahissants des îlots situés dans le lagon de Wallis. Dans cette optique, le personnel d'Island Conservation a travaillé conjointement avec celui du Service Territorial de l’Environnement de Wallis et Futuna au cours des mois de Septembre et Octobre 2019 pour entamer le travail de consultation et mieux comprendre les conditions nécessaires à la réussite d’un tel projet. Un panel de vertébrés introduits comprenant des rats, des chats et des cochons est présent sur l’ensemble des îlots du lagon de Wallis, sauf un. Ces espèces constituent une menace permanente pour les plantes et les animaux indigènes des îles et perturbent les processus écosystémiques responsables de la régénération des forêts indigènes et du bon état de santé des récifs. Différentes consultations avec les parties prenantes majeures ont été entreprises et tous les îlots ont été visités et expertisés. Aucun obstacle insurmontable au retrait des espèces envahissantes n'a été identifié et leur éradication est considérée comme réalisable. Une partie des îlots pourrait être traitée manuellement depuis le sol, tandis que les îlots présentant une topographie plus complexe nécessiteraient l'utilisation d’un moyen aérien de type drone pour épandre les appâts contenant le raticide. Préalablement au retrait des rats et des chats, les cochons devront être retirés des îlots où ils sont présents (stratégie présentée au sein de ce document). Des consultations plus approfondies sont essentielles pour fédérer un soutien du public au projet et pouvoir identifier les obstacles à résoudre avant de procéder à l'éradication. Les îlots de Wallis sont régulièrement visités et utilisés par la population. Par conséquent, d’importants efforts et un soutien de la part de la communauté Wallisienne seront nécessaires pour empêcher des réinvasions et assurer la pérennité des bénéfices du projet. Ce projet représente une véritable opportunité pour Wallis de protéger ses ressources naturelles et de développer sa capacité à gérer les problèmes liés aux espèces envahissantes.
Apolima Island Rat Eradication Feasibility Assessment

This report assesses the feasibility of eradicating rats from Apolima – a 115ha island inhabited by approximately 80 people, located in the Apolima Straight between the two main islands of Samoa. The Department of Conservation led the assessment, in collaboration with Samoa’s Ministry of Natural Resources and Environment, the South Pacific Regional Environment Programme, and the Apolima Island community. Rats have been eradicated from similar sized tropical islands with equally challenging terrain, but the steep slopes and cliffs on Apolima require poison bait to be applied from the air to succeed. This method of broadcast baiting is the logical method for the rest of the island in combination with more careful placement of bait around the village area.

The sea occupies three quarters of the area on the earth and provides various kinds of resources to mankind in the form of minerals, food, medicines and even energy. Seabed exploitation specifically with recovery of the resources that are found on the seabed, in the form of solids, liquids and gases. The resources are abundant, nevertheless the recovery process from the seabed, poses various challenges to mankind.
Ecological and socioeconomic impacts of invasive alien species in island ecosystems.

Minimizing the impact of invasive alien species (IAS) on islands and elsewhere requires researchers to provide cogent information on the environmental and socioeconomic consequences of IAS to the public and policy makers. Unfortunately, this information has not been readily available owing to a paucity of scientific research and the failure of the scientific community to make their findings readily available to decision makers. This review explores the vulnerability of islands to biological invasion, reports on environmental and socioeconomic impacts of IAS on islands and provides guidance and information on technical resources that can help minimize the effects of IAS in island ecosystems. This assessment is intended to provide a holistic perspective on island-IAS dynamics, enable biologists and social scientists to identify information gaps that warrant further research and serve as a primer for policy makers seeking to minimize the impact of IAS on island systems. Case studies have been selected to reflect the most scientifically-reliable information on the impacts of IAS on islands. Sufficient evidence has emerged to conclude that IAS are the most significant drivers of population declines and species extinctions in island ecosystems worldwide. Clearly, IAS can also have significant socioeconomic impacts directly (for example human health) and indirectly through their effects on ecosystem goods and services. These impacts are manifest at all ecological levels and affect the poorest, as well as richest, island nations. The measures needed to prevent and minimize the impacts of IAS on island ecosystems are generally known. However, many island nations and territories lack the scientific and technical information, infrastructure and human and financial resources necessary to adequately address the problems caused by IAS. Because every nation is an exporter and importer of goods and services, every nation is also a facilitator and victim of the invasion of alien species. Wealthy nations therefore need to help raise the capacity of island nations and territories to minimize the spread and impact of IAS.

This report was prepared as one of the outputs of the GEF PAS project “Prevention, eradication and control of invasive alien species in the Pacific islands” funded by the Global Environment Facility (GEF), implemented by the United Nations Environment Programme (UNEP) and executed by Secretariat of the Pacific Regional Environment Programme (SPREP) in partnership with the Department of Agriculture, Forestry and Fisheries of Niue (DAFF). It was designed to contribute to two activities in Niue’s programme within this project: 1. Develop and establish long term monitoring and GIS for areas with important native biodiversity that may be impacted by invasives. Huvalu Conservation Area, which is the subject of a project within the Regional Forestry and Protected Areas Management Project (FPAM), was identified as the key area for survey. 2. Conduct a pilot feasibility study for ten priority weed or vertebrate eradication targets.
