The Department of Conservation's efforts to cull Auckland Island pigs are being labelled a crime against humanity by the Rare Breeds Conservation Society. The pesky porcines are killing native plants, insects and seabirds - but they're also the only completely virus-free pig species, which scient

Successes and failures of rat eradications on tropical islands: a comparative review of eight recent projects

Rat eradication is a highly effective tool for conserving biodiversity, but one that requires considerable planning eff ort, a high level of precision during implementation and carries no guarantee of success. Overall, rates of success are generally high but lower for tropical islands where most biodiversity is at risk. We completed a qualitative comparative review on four successful and four unsuccessful tropical rat eradication projects to better understand the factors influencing the success of tropical rat eradications and shed light on how the risk of future failures can be minimised.

Dietary shift of an invasive predator: rats, seasbirds and sea turtles

The two most fundamental pieces of information necessary to begin developing ecological studies and conservation strategies for reptiles (or any organisms) are identifying the species and knowing what a species does in its natural habitat.

Archipelago-wide island restoration in the Galapagos Islands: Reducing costs of invaisve mammal eradication programs and reinvasion risk

Invasive alien mammals are the major driver of biodiversity loss and ecosystem degradation on islands. Over the past three decades, invasive mammal eradication from islands has become one of society's most powerful tools for preventing extinction of insular endemics and restoring insular ecosystems. As practitioners tackle larger islands for restoration, three factors will heavily influence success and outcomes: the degree of local support, the ability to mitigate for non-target impacts, and the ability to eradicate non-native species more cost-effectively.

Scaling down (cliffs) to meet the challenge: the Shiants’ black rat eradication

A successful ground-based eradication of black rats (Rattus rattus) was undertaken on the remote, uninhabited Shiant Isles of north-west Scotland over winter (14 October–28 March) 2015–16. The rat eradication was carried out as part of the Shiants Seabird Recovery Project, which aims to secure long-term breeding habitat for protected seabirds and to attract European storm petrels and Manx shearwaters to nest on the Shiants.

Terminal evaluation of UN Environment project: Prevention, control and management on invasive alien species in the Pacific island.

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 world’s important biodiversity hotspots, with high numbers of endemic species that are particularly vulnerable to extinction due to their limited habitat and isolation.

Invasion by the red-vented bulbul: an overview of recent studies in New Caledonia

New Caledonia is a tropical archipelago of the South Pacific Ocean, and is one of the 36 world biodiversity hotspots. However, its unique biodiversity is increasingly threatened by habitat fragmentation and introductions of invasive alien species. Among these invaders, the red-vented bulbul (Pycnonotus cafer) is currently expanding towards the north of the main island. This passerine features in the IUCN-ISSG list of the 100 worst invasive species of the world because of impacts caused by its diet.
