Working together with local communities, government management agencies, and conservation organizations, we select islands that have the greatest potential for preventing the extinction of globally threatened species. Among other benefits, the restoration project is is expected to prevent seven additional extinctions over the next 20 years and to permit four species to be returned to the island after having previously been lost due to predation by invasive rats and mice. The recently released Public Environment Report (PER) for the Lord Howe Island rodent eradication calculates that the net social benefit from implementing the plan is $141M over 30 years.

Keep uρ the great works guys I’ve included you guys to my own blogroll. The island wide strategic Weed Eradication Program commenced in 2004, building on earlier years of ad-hoc control effort. The program’s significant outcomes have been recognised through the IUCN Conservation Outlook which in 2017 scored the Lord Howe Island Group’s outlook as good, primarily due to the success of projects that have, are being and are planned to be implemented to restore and protect the islands unique World Heritage values. To achieve this, the consultants commissioned by the Board compared the likely economics outcomes from two scenarios—the island ecosystem with and without invasive rodents—over a 30-year period.

A unique and endangered palm-forest ecosystem would be restored to health and other World Heritage values maintained. The team work at a diversity of sites that are at different stages of restoration, as well as a range of vegetation communities from highly degraded sites requiring reconstruction methods to high conservation value vegetation requiring assisted regeneration methods. Techniques & methodology At least 68 species are the focus for eradication (Fig 1), with 10 main invasive species having colonised extensive areas of the settlement and the PPP, posing a serious threat to island habitats. Weeds are prioritised for eradication following a Weed Risk Assessment and are typically species that are at low density, are localised and/or are limited to gardens, and species with known weed characteristics (e.g. This loss will be more than compensated for by the temporary workforce in any case.
