This project aims to evaluate the hypothesis that arboreal species are limited by the abundance of tree hollows, and that historical increases in the frequency of intense fires may be reducing hollow abundance. Northern Australia’s mammals are in severe decline, and arboreal species are among those that have fared worst. There is abundant anecdotal evidence that a decline in hollow abundance is the cause. Working with the Western Australian Department of Parks and Wildlife in the Kimberley, the last region on the Australian mainland with an intact mammal fauna, the project aims to explore management options for increasing the availability of hollow denning sites for arboreal mammals (e.g. fire management, artificial nest boxes), and evaluate the likely impact of such actions on mammal populations across northern Australia.

该项目旨在评估树栖物种受到树洞丰富度限制的假设，以及历史上激烈火灾频率的增加可能会减少空洞丰富度。澳大利亚北方的哺乳动物数量正在严重下降，树栖物种是其中最糟糕的。有大量的轶事证据表明，空心丰度的下降是原因。该项目与西澳大利亚州公园和野生动物部合作，在澳大利亚大陆上最后一个拥有完整哺乳动物区系的地区-金伯利开展工作，目的是探讨管理备选方案，以增加树栖哺乳动物中空栖息地的可用性（例如火灾管理、人工巢箱），并评估此类行动对澳大利亚北方各地哺乳动物种群的可能影响。
