In the last 30 years, islands and fenced exclosures free of introduced predators (collectively, havens) have become an increasingly used option for protecting Australian mammals imperiled by predation by introduced cats (Felis catus) and foxes (Vulpes vulpes). However, Australia's network of havens is not expanding in a manner that maximizes representation of all predator‐susceptible taxa, because of continued emphasis on already‐represented taxa. Future additions to the haven network will improve representation of mammals most efficiently if they fill gaps in under‐represented predator‐susceptible taxa, particularly rodents. A systematic approach to expansion could protect at least one population of every Australian predator‐susceptible threatened mammal taxon by the addition of 12 new havens to the current network. Were the current haven network to be doubled in number in a systematic manner, it could protect three populations of every Australian predator‐susceptible threatened mammal taxon.

系统的规划可以迅速缩小澳大利亚哺乳动物避风港的保护缺口

在过去的30年中，没有外来掠食者（统称为避难所）的岛屿和围栏已成为保护受引进猫（Felis catus）和狐狸（Vulpes vulpes）的掠食行为危害的澳大利亚哺乳动物的一种越来越多的选择。）。但是，澳大利亚的避风港网络并没有以最大限度扩大所有捕食者易感类群的代表性的方式扩展，因为继续强调已经存在的类群。如果它们弥补了代表性不足的捕食者易感类群（尤其是啮齿类动物）中的空白，那么将来向避风港网络中添加的动物将最有效地提高哺乳动物的代表性。通过在当前网络中添加12个新的避风港，一种系统的扩展方法可以保护每个澳大利亚掠食性易感威胁哺乳动物分类群的至少一个种群。如果当前的避风港网络数量以系统的方式增加一倍，它可以保护每个澳大利亚掠食性易感威胁哺乳动物分类群的三个种群。
