Abstract

Megafires can have a devastating effect on koala populations. With climate change increasing habitat vulnerability to wildfires, understanding how to efficiently measure the impact of these events on koalas is essential. We analysed the relationship between the 2019-2020 megafires and the probability of koala occurrence in Mid North Coast NSW. We found that two on-field and one satellite-derived variables measuring fire severity equally explained koala occurrence. The probability of koala occurrence decreased with increasing fire severity. This supports the use of remote sensing imagery to efficiently monitor the impact of future fire events on koala populations in the region.

巨型火灾与考拉的出现：实地数据与卫星图像的比较分析

特大火灾会对考拉种群造成毁灭性影响。随着气候变化加剧了栖息地对野火的脆弱性，了解如何有效衡量这些事件对考拉的影响至关重要。我们分析了 2019-2020 年大火与新南威尔士州中北海岸考拉出现概率之间的关系。我们发现，测量火灾严重程度的两个现场变量和一个卫星衍生变量同样可以解释考拉的出现。考拉出现的概率随着火灾严重程度的增加而降低。这支持利用遥感图像有效监测未来火灾事件对该地区考拉种群的影响。

期刊介绍： Australian Mammalogy is a major journal for the publication of research in all branches of mammalogy. The journal’s emphasis is on studies relating to Australasian mammals, both native and introduced, and includes marine mammals in the Antarctic region. Subject areas include, but are not limited to: anatomy, behaviour, developmental biology, ecology, evolution, genetics, molecular biology, parasites and diseases of mammals, physiology, reproductive biology, systematics and taxonomy. Australian Mammalogy is for professional mammalogists, research scientists, resource managers, consulting ecologists, students and amateurs interested in any aspects of the biology and management of mammals. Australian Mammalogy began publication in 1972 and is published on behalf of the Australian Mammal Society.
