Invasive species threaten many of Australia's unique flora and fauna. Our island ecosystems have evolved in the absence of mammalian predators, and are therefore particularly vulnerable. When both cats and rats invade an island, they can quickly decimate the populations of native species, particularly seabirds, and threaten them with extinction. Unfortunately, poorly planned eradication of these invasive species can destabilise the complex island ecosystems, further endangering the native species. The results of this project will help conservation managers to plan eradication strategies that cost-effectively eradicate populations of two introduced species, without threatening native wildlife.

入侵物种威胁着澳大利亚许多独特的动植物。我们的岛屿生态系统是在没有哺乳动物捕食者的情况下进化的，因此特别脆弱。当猫和老鼠入侵一个岛屿时，它们可以迅速摧毁当地物种的数量，尤其是海鸟，并使它们面临灭绝的威胁。不幸的是，计划不当的根除这些入侵物种会破坏复杂的岛屿生态系统的稳定，进一步危及本地物种。这个项目的结果将帮助保护管理者制定消灭策略，在不威胁本地野生动物的情况下，经济有效地消灭两种引进物种的种群。
