Battling Invasive Species Session

Island and Ocean Ecosystems, BRB

Available Online

PRISMSS

Invasive species are a key issue for biodiversity and ecosystem resilience in the Pacific. This session will take you on a journey through the Pacific with 28 Invasive Species Battler’s, experts and donors. We will update you on the current state of invasive species in the Pacific, some of their impacts, some challenges and some solutions.

Biological invasions are a global phenomenon that threatens biodiversity, and few, if any, ecosystems are free from alien species. The outcome of human-mediated introductions is affected by the invasiveness of species and invasibility of ecosystems, but research has primarily focused on defining, characterizing and identifying invasive species; ecosystem invasibility has received much less attention. A prerequisite for characterizing invasibility is the ability to compare levels of invasion across ecosystems. In this paper, we aim to identify the best way to quantify the level of invasion by nonnative animals and plants by reviewing the advantages and disadvantages of different metrics. We explore how interpretation and choice of these measures can depend on the objective of a study or management intervention. Based on our review, we recommend two invasion indices and illustrate their use by applying them to two case studies. Relative alien species richness and relative alien species abundance indicate the contribution that alien species make to a community. They are easy to measure, can be applied to various taxa, are independent of scale and are comparable across regions and ecosystems, and historical data are often available. The relationship between relative alien richness and abundance can indicate the presence of dominant alien species and the trajectory of invasion over time and can highlight ecosystems and sites that are heavily invaded or especially susceptible to invasion. Splitting species into functional groups and examining invasion patterns of transformer species may be particularly instructive for gauging effects of alien invasion on ecosystem structure and function. Establishing standard, transparent ways to define and quantify invasion level will facilitate meaningful comparisons among studies, ecosystem types and regions. It is essential for progress in ecology and will help guide ecosystem restoration and management.

Thomas, Peter.

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 worlds 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 countrys 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.

Multilateral environmental agreement negotiator's handbook : Pacific region

Clark, Peteru

Taylor, Prue

The first and second editions of the Handbook, on which this Pacific version is substantially based, were prepared as a practical introduction to negotiating or working on Mulitlateral Environmental Agreements (MEAs). They were prepared for people with little or no technical background in negotiations.They were also intended to function as a key reference tool for experienced negotiators. As a result the subject matter is developed at a relatively broad level. However, technical information and language was retained and used in context, with understanding facilitated by a comprehensive glossary prepared by UNEP. This new handbook preserves these key aspects but has enhanced the accessiblity of information and, were appropriate, used examples and material of particular relevance to the Pacific Region

Towards establishing a Melanesia bio-security & invasive species advisory committee

Available Online

The purpose of this report is to provide an overview of the various frameworks and initiatives that exist in the Pacific Island Countries and Territories (PICTs) with regards to invasive species management and how they could be utilised towards the development of a coordinated mechanism by the countries in the Melanesian region in addressing biosecurity and invasive species concerns. The terms of reference for this report can be seen in Annex 1. The benefits from a coordinated region may include enhanced economic opportunities and safeguarding the unique ecological systems and species diversity for the wellbeing of the Melanesian people. The PICTs are one of the best organised and well-coordinated regions in the world in terms of environmental management. Comprising thousands of islands, atolls and islets, the Pacific Islands are categorised in many different ways including the three sub-regions of Melanesia, Micronesia and Polynesia (generally in reference to the size and cultural context of the islands and people).
