Vanderwoude, Casper... [et al.]

The little re ant, Wasmannia auropunctata, is a small ant native to Central and South America, which has been introduced into a third of the Paci c region's island groups. It is considered by invasive experts to be the greatest ant species threat within the Paci c islands region.

Guam invasive species management plan interim 2017-2019: interim

Available Online

The 2017-2019 Interim Guam Invasive Species Management Plan (GISMP) expresses the overarching goals and priorities of the Guam Invasive Species Council (GISC or Council). The Guam Invasive Species Act of 2011 (Public Law 31-43) established the Council as Guams lead entity in coordinating with local, regional, national, and international jurisdic¬tions in the fight against alien invasive species. Although the GISC is in its infancy stages of organization, it draws from the collective knowledge, past research, and progress of its members in establishing the Councils goals and priorities. Priorities and goals identified in this plan reflect current and near-term resources, member capabilities, and status of certain invasive species. Recommendations contained in the Regional Biosecurity Plan for Micronesia and Hawaii (RBP), the 2016-2018 National Inva¬sive Species Councils Management Plan, the Regional Invasive Species Council (RISC), and various stakeholders were considered in the development of this plan. The Council also considered developments under the purview of the Hawaii Invasive Species Council and its 2015-2020 HISC Strategic Plan.

In 2014, with support from the French Government, Wallis and Futuna informed SPREP of its intention to identify nationally significant wetlands for future designation as wetlands of international importance (Ramsar Sites) under the Convention on Wetlands (Ramsar, Iran, 1971).

Rat eradication in the Pitcairn Islands, South Pacific: a 25-year perspective

Island and Ocean Ecosystems, BRB

Available Online

Brooke, M.de L.

This essay offers a 25-year overview of eff orts to remove Pacific rats (Rattus exulans) from the four islands of the Pitcairn group. Following the 19911992 discovery that rats were severely reducing breeding success of gadfly petrels (Pterodroma spp.), Wildlife Management International proposed eradication. Eradication success was achieved using ground-based baiting on the small atolls of Ducie and Oeno in 1997, and there is now evidence of petrel recovery on Oeno, but two eradication attempts on inhabited Pitcairn (1997 and 1998) failed. By the early 2000s, the development of aerial baiting through the 1990s placed an eradication operation on the fourth island, Henderson, within reach. Preparatory fieldwork in 2009 allayed doubts in two key areas: the feasibility of maintaining a captive back-stop Henderson rail (Porzana atra) population, and bait uptake by crabs (Coenobita spp.). Royal Society for the Protection of Birds (RSPB) expertise secured the necessary funding of £1.5 million, and 75 tonnes of brodifacoum-containing bait were dropped in August 2011. Despite extensive mortality of free-living rails, the population, supplemented by released captive birds, returned to pre-operational levels in 23 years. Meanwhile those tending captive rails saw no rat sign before leaving Henderson in November 2011. Unfortunately, a rat was sighted in March 2012, and continuing rat presence confirmed in May 2012. Subsequently rat numbers have returned to pre-operational levels without any sign of population overshoot as observed on Pitcairn. Genetic analysis suggests around 80 rats, roughly 1 in 1,000, survived the bait drop. With no evidence of imperfect bait coverage or deficiencies in bait quality or brodifacoum resistance, it seems some animals chose not to eat bait. Choice tests on Henderson Island rats suggest some rats prefer natural foods over bait. This adverse situation may have been exacerbated because, in August 2011, natural fruits were more abundant than anticipated due to drought earlier in the year. To overcome rat preference for natural food, any second Henderson attempt might benefit from more attractive bait. Without such developments, a second attempt risks another failure. Hendersons biota will survive the delay.

Invasive ants as a biosecurity threat.

Available Online

Invasive ants are a diverse group of aggressive, competitive, dominating ant species that can rapidly establish and spread. Several ant species are amongst the most serious global invasive species. Their broad diets, nesting habits, ability to breed rapidly, high densitites and adaptibility to varied habitats make them excellent invaders. Agricultural economic, environmental and social wellbeing are threatened by these ants, many of which have been introduced to, and established in, many countries
