Abstract

Feral cats are known to drive numerous extinctions of endemic species on islands. Predation by feral cats also currently threatens many species listed as critically endangered. Island faunas that have evolved in the absence of mammalian predators are particularly susceptible to cat predation. Dirk Hartog Island is no exception as cats have caused the local extinction of its once high vertebrate diversity. A programme to reconstruct the native fauna on the island necessitated feral cat eradication. In this paper we outline the strategy, removal techniques and monitoring methods used in this successful eradication of feral cats. Globally, the Dirk Hartog project has become the largest successful island feral cat eradication campaign attempted to date.

西澳大利亚州德克·哈托格岛上的野猫根除

摘要

众所周知，野猫会导致岛屿上许多地方性物种灭绝。野猫的捕食目前还威胁着许多被列为极度濒危的物种。在没有哺乳动物捕食者的情况下进化的岛屿动物特别容易受到猫的捕食。德克·哈托格岛也不例外，因为猫已经使它曾经高度脊椎动物的多样性在当地灭绝。重建岛上原生动物的计划需要消灭野猫。在本文中，我们概述了成功消除野猫的策略，清除技术和监测方法。在全球范围内，德克·哈托格（Dirk Hartog）项目已成为迄今为止最大规模的成功消除岛上野猫行动。
