While invasive species eradications are at the forefront of biodiversity conservation, ant eradication failures are common. We reviewed ant eradications worldwide to assess the practice and identify knowledge gaps and challenges. We documented 316 eradication campaigns targeting 11 species, with most occurring in Australia covering small areas (b10 ha). Yellow crazy ant was targeted most frequently, while the bigheaded ant has been eradicated most often. Of the eradications with known outcomes, 144 campaigns were successful, totaling approximately 9500 ha, of which 8300 ha were from a single campaign that has since been partially re-invaded. Three active ingredients, often in combination, are most commonly used: fipronil, hydramethylnon, and juvenile hormone mimics. Active ingredient, bait, and method varied considerablywith respect to species targeted,which made assessing factors of eradication success challenging. We did, however, detect effects by active ingredient, number of treatments, and method on eradication success. Implementation costs increased with treatment area, and median costs were high compared to invasive mammal eradications. Ant eradications are in a phase of increased research and development, and a logical next step for practitioners is to develop best practices. A number of research themes that seek to integrate natural history with eradication strategies and methodologies would improve the ability to eradicate ants: increasing natural history and taxonomic knowledge, increasing the efficacy of active ingredients and baits, minimizing and mitigating non-target risks, developing better tools to declare eradication success, and developing alternative eradication methodologies. Invasive ant eradications are rapidly increasing in both size and frequency, and we envisage that eradicating invasive ants will increase in focus in coming decades given the increasing dispersal and subsequent impacts.

NESSC Quarterly Meeting No. 5, Thursday 25 August, 2016

Final report for Samoa's 2015 national water and sanitation baseline survey, on methods, results and outcomes.

Before you leave Samoa, stop and think... Could you be breaking wildlife laws? Souvenirs and handicrafts can sometimes include plant and animal products that are protected under the Convention on International Trade of Endangered Species of Wild Fauna and Flora (CITES).

Samoa is home to many threatened species including corals, marine turtles, whales, dolphins and more. The survival of these species is further endangered by the global trade in plants, animals and products that may be made from them.

Samoa's National Environmental Capacity Strategy (NECS) is drawn on the assessment and analysis of priority thematic and cross-cutting capacity needs. These needs have identified priority actions for capacity development and opportunities to promote synergies across the 3 Conventions which are highlighted as project profiles in the NECS. Strategies to implement these project profiles including means of monitoring and evaluation of outcomes are also highlighted in the NECS.

Protecting a species is an aspect of conservation which many organizations and individuals have put effort into so that the balance within the ecosystem can be maintained. Protection implement when factors of threats have been identify. Factors of pressure or predatory that may lead to competition and results in extinction. These are the sequence our world works since the beginning

The community based conservation (CBC)paradigm predicts that sustainable biodiversity can only be achieved if local people perceive benefits from conservation. Through interviews, the situation in Samoa portrays that the CBC of mangroves was received with apprehension because the mangrove biodiversity was more significant than sustaining the livelihood of the local communities. In contrast, Iriomote Island residents were able to achieve maximum socio-economic benefits but to the extent that they were over commercializing the mangrove ecosystem. More research is imperative to find out how biodiversity conservation can be married with sustainable development objectives to sustain the local communities' livelihood.
