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).

Trail cameras are a key monitoring tool for determining target and non-target bait-take during rodent removal operations: evidence from Desecheo Island rat eradication

Efforts to remove invasive rodents (e.g. Rattus spp. and Mus musculus) from islands often use toxicant-laced baits containing the anticoagulants brodifacoum or diphacinone. Rodenticide baits are generally delivered through aerial- or hand-broadcast, or in bait stations. These baits are not rodent-species and are subject to non-target consumption or secondary exposure (e.g. an individual preying upon another individual that has consumed bait). During rodenticide applications, it is generally unknown which animals are visiting and consuming bait; and to quantify this, we recommend using trail cameras (e.g. Reconyx motion-activated infra-red) positioned to monitor individual bait pellets. To demonstrate the importance and effectiveness of using trail cameras during such operations, we report results of target (Rattus rattus, black rat) and non-target (native land crab, lizard, insect) bait-interactions after an aerial-broadcast of Brodifacoum-25D Conservation to eradicate rats from Desecheo Island, Puerto Rico. During the ?rst ?ve days following bait application, trail cameras (n = 15) revealed that there were 40 incidences of animals contacting bait pellets: 50% rat, 32% hermit crab, 13% Ameiva lizard, and 5% insect. Trail cameras provide temporal and spatial information regarding the e?ectiveness of rodent removal, and the last rat pictured by trail cameras on Desecheo was six days after bait application began. Trail cameras revealed 30 incidences of animals contacting bait pellets 620 days after bait application began: 47% hermit crab, 37% Ameiva lizard, 13% insect, and 3% black crab. Despite viewing ~69,000 images from trail cameras, lizards were never pictured consuming bait on Desecheo; therefore, any brodifacoum exposure to Desecheo lizards likely occurred via secondary pathways (e.g. consumption of contaminated insects). Scaling up, we estimate that > 75% of the total bait distributed on Desecheo was not consumed by rats. Trail cameras help inform the hazards of rodenticide use and can be easily incorporated into rodent removal operations.

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
