The clean boats, clean ports framework is a Pacific Regional Invasive Species Management Support Service (PRISMSS) Protect our Islands (POI) initiative to enable countries to better secure international entry ports that are gateways to priority domestic destinations. This Battler Series publication supports the prevention of the spread of invasive species among islands within countries. The document outlines a flexible framework that recognises the diverse situations in Pacific island countries and territories and that capitalises on existing strengths, while highlighting achievable and aspirational targets. This publication is part of a collection of Battler guides on preventing the spread of invasive species in the Pacific region.

While eradication projects on large islands require substantial funding and a high level of technical and logistical support, projects on small islands are much simpler and can achieve success with much less funding and outside assistance. The Pacific has thousands of such islands that can contribute to significant biodiversity outcomes. The purpose of this guide is to assist the practitioner in removing invasive rodents from small islands (less than 20 hectares) where access to all parts of the island is possible. These guidelines are designed to be used in conjunction with the resource 'Use anticoagulant rodent bait safely'. Thanks to our partner Island Conservation, who drafted this guide following the successful removal of rodents on Motutapu and Malinoa islands in the Kingdom of Tonga.

Anticoagulant rodenticides are an important tool for managing rodents by increasing the chances of success and lowering the resources required. This guide was developed to assist non-specialists in gaining a better understanding of the risks, costs, and benefits of using anticoagulant rodenticides. Everyone has a role to play in ensuring that rodenticides are used responsibly and that the risk of negative impacts to people and the environment is minimised. Failure to do so could result in the loss of support for the use of these useful tools.

The presence of invasive species generally leads to negative impacts, some perhaps irreversible, and the economic costs from the impacts and their management can be substantial and long-lasting. Efforts to understand the extent of damages caused by invasive species are slowly gaining momentum globally; however, in many countries, efforts are only beginning. This guide will assist Pacific island practitioners to use the costs that result from invasive species incursions to gain support to fund prevention, management, restoration, research and outreach. SPREP thanks James Stanford, Aaron Buncle, and Jarrod Troutbeck, who advised the development of this guide.

The invasive battler has a difficult job. Many of the management solutions for invasive species require a broad base of information to determine the best way to approach an issue and determine if the approach is feasible. Likely questions a battler will face are: what is that species? How did it get here and where will it go next? Is it a risk to our environment or other important national asset? Where else is this species found and what did they do about it? This guide was developed to assist the invasive species battler in accessing information to answer these questions and decide about management action.|SPREP thanks Shyama Pagad from the Invasive Species Specialist Group (ISSG) for drafting this guide. The ISSG performs a vital role in storing and making available invasive species data for the Pacific.

Experience shows that you can get rid of myna while their population is small, but once the population becomes widespread, ongoing management will be required if the impacts of myna are to be reduced. This guide offers solutions and advice on how to decide what to do if myna are an issue in your country and was prepared by David Butler and Bill Nagle, who have assisted Pacific countries with myna solutions for both goals of eradication and control.

Dealing with invasive species is a huge job. Invasive species are everyone's responsibility, but people can only help if they are aware and know what they can change to make a difference. This guide is designed to support your creation of cost-effective communications campaigns to reduce the impact of invasive species in Pacific Island nations. Thanks to Steve Menzies and the Pasifika Collective for assisting with the design of the campaign, assisting and advising SPREP through the process, and preparing the draft text for this guide. In January 2015, the Invasive Species team from (SPREP) began a targeted public campaign to stop the spread of the little fire ant across the Pacific. This guide uses examples from the "Stop the Little Fire Ant!" campaign to highlight the key steps needed to develop and implement an effective strategy.

National or Territory Invasive Species Strategies and Action Plans (NISSAP) are a critical document to ensure invasive species management is coordinated within a country or territory and that the different sectors involved with invasive species management are working together toward the same goals. NISSAP are essential to show political will for managing invasive species and are looked upon favourably by funding bodies.

Marine invasive species have received much less attention than terrestrial species worldwide. In the Pacific, the marine environment provides us with a significant part of our diet and income. Marine Managed Areas focus on protecting these important resources for livelihood purposes, biodiversity and ecosystem function, tourism and many other benefits. Although invasive species management is more difficult in the marine environment, it is not something we can neglect, and the efforts we put in need to increase. This guide seeks to provide some options for this management. Special thanks to Anne Haas, who completed an internship with the SPREP Invasive Species Programme from Yale University in 2015, for completing the literature review and creating the text for this guide.

Graphs use spatial arrangement on the page or screen to convey numerical information: they are often easier to interpret than repetitive numbers or complex tables. The assumption seems to be made that creating good graphs is easy and natural: yet many bad or sub-optimal graphs encountered in the literature disprove this. We aim to help you to produce good graphs, and to avoid falling into traps that common computer software packages seem to encourage. A scientific culture is one where good graphs, and innovative and specialised approaches, are valued. Hence we explain some relevant psychology behind the interpretation of graphs. We then review a variety of graph formats, including some less common ones. Their appropriate uses are explained, and suggestions are given for improving the visual impact of the message behind the data while reducing the distraction of non-essential graphical elements. We argue against the use of pie charts and most three- dimensional graphs, prefer horizontal to most vertical bar charts, and recommend using box plots and multipanel graphs for illustrating the distribution of complex data. The focus of this publication is on preparing graphs for written communications, but most principles apply equally to graphs used in oral presentations. The appendices illustrate how to create better graphs by manipulating some of the awkward default settings of Microsoft Excel ( 2002 version) and illustrate the S-PLUS programming language (both programs are currently available on the computer network of the New Zealand Department of Conservation).
