In 1998, Double and Outer Islands, off Spring Point, West Falkland, were acquired by Falklands Conservation3, and rat eradication started in 2000, covering these islands and two others, Top and Bottom Islands at Port William1. In total, rats have now been eradicated from 22 islands6. Of the remaining islands within the range, 162 are known to have no introduced land predators, 75 have confirmed rats and/or mice present and a further 553 have not been surveyed (most of them are small or tiny islands)7. Conservation Actions Proposed
Continue surveys to monitor population trends. Conduct ecological studies in order to understand the necessary conditions for the species's conservation4. Eradicate rats from selected small islands covered with mature tussock-grass to encourage recolonisation4,5.
