After decades of biodiversity loss and economic burden caused by the brown treesnake invasion on the Pacific island of Guam, relief hovers on the horizon. Previous work by USDA Wildlife Services (WS) and its National Wildlife Research Center (NWRC) demonstrated that brown treesnake numbers in forested habitats can be dramatically

Biological control of weeds in Vanuatu began in 1935, with the introduction of the tinged Teleonemia scrupulosa to control Lantana camara. To date, nine biological control agents have been intentionally introduced to control eight weed species. Seven of these agents have established on their respective hosts while an eighth, Zygogramma bicolorata, an agent for Parthenium hysterophorus has only recently been released and establishment is unlikely.

The main outcome of the project was the control or significant reduction of chromolaena in most provinces of PNG. Areas that were once monostands of chromolaena have been converted back into subsistence farms, and plantations in which chromolaena was the main understorey species are now clear of the weed. This outcome was the result of the primary outputs of the project: (a) knowledge of the extent of the chromolaena problem and its impact of the livelihoods of smallholders, (b) an understanding of effective biocontrol agents and (c) significant capacity built in biocontrol of weeds.

This document is to report on the work carried out to assess the status and the possibility of controlling beach burr (Cenchrus Echinatus) on the island of Pukapuka. This work was conducted by the National Environment Service and funded under the Regional Invasive species program.

The Island of Suwarrow and its surrounding waters was declared a National Park in 1978 under the Conservation Act 1975. The legal opinion sought in 2001 clarifies that Suwarrow is Crown Land. Today, Suwarrow is under the jurisdiction of the National Environment Service (NES) since 2003, for the primary purpose of conserving, preserving, protecting and managing the natural resources of Suwarrow.

This report outlines the work carried out to control Red Passionfruit (Passiflora Rubra) on the island of Mauke. Treatment methods used in controlling Red Passionfruit on Mauke, monitoring and analysis of data collected throughout the last 2 years were highlighted.

To enhance their conservation value, several hundred islands worldwide have been cleared of invasive alien rats, Rattus spp. One of the largest projects yet undertaken was on 43 km2 Henderson Island in the Pitcairn group, South Pacific, in August 2011. Following massive immediate mortality, a single R. exulans was observed in March 2012 and, subsequently, rat numbers have recovered. The survivors show no sign of resistance to the toxicant used, brodifacoum.

This plan covers the proposed operations to eradicate feral cats (Felis catus) from Malden Island, an uninhabited Wildlife Sanctuary within the southern Line Island group, part of the Republic of Kiribati.

A programme to eradicate two species of myna from Kiribati was carried out between November 2014 and November 2015 by staff of the Environment & Conservation Division, Ministry of Environment, Lands and Agricultural Development with funds through the regional GEF-PAS Invasives project coordinated by UNEP and SPREP, assisted by international consultant Dave Butler.
