Improving invasive ant eradication as a conservation tool : a review

Available Online

Hoffman, Benjamin ... et al.

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.

Will climate change impact the potential distribution of a native vine (Merremia peltata) which is behaving invasively in the Pacific region?

Kumar, Lalit

Taylor, Subhashni

Merremia peltata is a species with uncertain status in the island nations of the Pacific region. It has been designated introduced and invasive in some countries whereas it is considered native in others. Recent increase in its abundance across some island landscapes have led to calls for its designation as an invasive species of environmental concern with biological control being suggested as a control strategy. Climate change will add to the complications of managing this species since changes in climate will influence its range limits. In this study, we develop a process-oriented niche model of M. peltata using CLIMEX to investigate the impacts of climate change on its potential distribution. Information on the climatic requirements of M. peltata and its current geographic distribution were used to calibrate the model. The results indicate that under current climate, 273,132 km2 of the land area in the region is climatically unsuitable or marginal for M. peltata whereas 664,524 km2 is suitable to highly suitable. Under current climate, areas of climatic suitability for M. peltata were identified on the archipelagos of Fiji, Papua New Guinea, Solomon Islands and Vanuatu. By the end of the century, some archipelagos like Fiji, Hawaii, New Caledonia and Vanuatu will probably become more suitable while PNG and Solomon Islands become less suitable for M. peltata. The results can be used to inform biosecurity planning, management and conservation strategies on islands.

2017 Pacific Environment Forum : connecting the dots - environment, knowledge and governance

Available Online

The Pacific Environment Forum (PEF) is an initiative by the Secretariat to meet long standing member requests for a more informal setting to facilitate discussion amongst officials and other stakeholders on key environmental, technical and institutional issues. The PEF is held prior to the SPREP Meeting (SM) allowing for the outcomes to be tabled at the SM for its consideration. The PEF was held for the first time in 2011.

Guidelines on business and KBAs: managing risk to biodiversity

The KBA Partnership

These Guidelines on business and KBAs have been developed by the KBA Partners to support businesses in managing risk to biodiversity. They will be of use to business and certification scheme operators, financial institutions, civil society organisations, and public authorities. They are applicable to the businesses entire area of influence, as well as throughout the life cycle of the operation, from pre-feasibility to closure (and, where relevant, site rehabilitation). The Guidelines can also be integrated into responsible sourcing policies for goods and services, the production of which could have direct, indirect, and cumulative impacts on KBAs.

The National Environment Sector Plan (NESP) Samoa : 2017-2021

Available Online

The NESP 2017-2021 updates the NESP 2013-2016. It is based on the most recent State of the Environment assessment documented in 2013, lessons learned from the previous NESP and outcomes of the Sector SWOT Analysis which was conducted as part of the NESP review and update process. The NESP articulates the roadmap for the Environment Sector for the period 2017 - 2021. It outlines the sector's vision, goal and an achievable framework for action, in line with the Strategy for the Development of Samoa (SDS) 2016-2020, the sector policy and legislative framework and regional and international obligations. The framework consists of 4 long term outcomes under which 15 end of sector plan outcomes will be pursued.

Pacific aims to up influence in fight against climate change

Available Online

Nihmei, Salesa

The Pacific's environmental agency is looking to increase the region's input into climate change decisions made at a global level. SPREP is co-hosting a workshop in Samoa with the Australian scientific research body, the CSIRO, to develop a regional strategy for climate research. Considering the direct impact of a warming planet and a changing environment on Pacific countries, the region has had little input into climate change negotiations at the United Nations or Intergovernmental Panel. SPREP's meteorology and climate officer Salesa Nihmei says this workshop aims to change that. Mr Nihmei told Dominic Godfrey that key regional stakeholders are in Apia to work on a research strategy that will benefit the global fight against climate change.

Contribution of marine conservation agreements to biodiversity protection, fisheries management and sustainable financing in Fiji

Sykes, H.

The marine environment is a vital resource for Fiji's tourism, yet industry and community efforts to conserve and improve it have largely gone unrecognised, and are under-utilised in Fiji's tourism marketing. The Wildlife Conservation Society and Marine Ecology Consulting conducted a study between 16 March and 30 October 2017 to document the degree and scale to which Marine Conservation Agreements (MCAs) are being used in coastal waters in Fiji, and what contribution they are making to biodiversity conservation, fisheries management and sustainable financing. The study focuses on partnerships involving local communities with land-sea tenure rights and the tourism sector. It concentrates on the experiences and perceptions of the tourism sector, some of whom are local operators and resource owners. Documenting the motivations and opinions of the community resource owners was outside the scope of this study, and could usefully form the basis of a companion study to better understand their perceptions and commitment to the MCAs, and the direct and indirect benefits they receive.
