management actions

In June/July 2002 the eradication of Pacific rats from Maninita Island in the Vava'u group of the Kingdom of Tonga was attempted using Brodifacoum pellets in bait stations. In December 2002, Maninita was revisited and rat trapping carried out to determine if rats were present. While no rats were caught and none were seen, further monitoring in June 2003 is recommended before the island is declared "rat free '.

In 1989, the kakerori (Pomarea dimidiata) was one of the 10 rarest birds in the world with a declining population of just 29 individuals living in forested hill country in the Takitumu Conservation Area (TCA) of south-eastern Rarotonga, Cook Islands. Following 12 years of rat poisoning, the population had increased to 255 birds in August 2001. The programme then shifted from ‘species recovery’ to ‘sustainable management’ of the Rarotonga population at 250 to 300 birds. The rat poisoning effort was reduced, and an ‘insurance’ population was established on Atiu.

Protected areas are a key component of any global conservation strategy. tourism provides a crucial and unique way of fostering visitors' connection with protected area values, making it a potentially positive force for conservation. Visitor experiences can be transformative. Tourism and visitor management in protected areas: Guidelines for sustainability. Tourism for an individual's personal growth and well-being, while instilling an increased sense of stewardship and support for protected area values

Australia can’t afford to allow in any more insect colonists like red imported fire ants, electric ants, browsing ants, yellow crazy ants, Argentine ants, African big-headed ants, Asian honeybees, large earth bumblebees and German wasps. These invaders are costing both the Australian environment and economy dearly. Hundreds of millions of dollars are being spent on Australia-wide eradications of red fire ants, electric ants and browsing ants because of their potential for devastating harm to wildlife and impacts on people.

The small uninhabited island of Monuriki (40.4 ha) in western Fiji is of national and international conservation concern for its several protected species. Exotic invasive species and a Category 5 cyclone have exacerbated conservation challenges. The cooperation of local, national, and international stakeholders continues to be crucial in restoration of the island’s native ?ora and fauna. This summary presents a timeline of restoration efforts and current status of the recovery programme for Monuriki.

Considerable bene?ts can be achieved for indigenous biodiversity when invasive vertebrates are removed from islands. In New Zealand, two logistically challenging eradications were undertaken, one to remove cats (Felis catus) and the other Paci?c rats (Rattus exulans) from Te Hauturu-o-Toi/Little Barrier Island (Hauturu). Here we document the short- and long-term impacts of these interventions on the biodiversity of Hauturu. We also assess the extent to which predicted outcomes were re?ected in the measured responses for a wide range of species.

Suite à la soutenance de thèse effectuée en juillet 2018 à l’Université de Massey, le manuscrit de Martin Thibault, intitulé « Le bulbul à ventre rouge (Pycnonotus cafer): dynamique d’invasion et impacts écologiques d’un oiseau introduit en Nouvelle Calédonie. Invasive alien species are a major cause of biodiversity loss globally, especially on islands where high species richness and levels of endemism accentuate their impacts.
