Guide

The importance of natural resources to the economy of the Pacific island region cannot be overstated. Island communities have unsurprisingly relied heavily on ocean resources for sustenance and economic activities, such as fishing and transport. Land-based resources are also vital at subsistence level, and are providing increasing development opportunities, for example through forestry and mineral mining.

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.

Early Detection and Rapid Response (EDRR) systems are the first line of defence against invasive species once they have penetrated national or inter-island biosecurity systems. For these systems to be effective, a plan is required to coordinate the responsible agencies and ensure both the systems and equipment to address the detected species are in place prior to the response. Several countries have developed these plans recently, which are available on the Battler Resource Base. SPREP thanks James Stanford, who drafted the text for 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?

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.

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.

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.

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.
