干旱、人为气候变化和现有的土地使用管理加剧了澳大利亚 2019-2020 年的特大火灾。在这里，结合遥感数据和物种分布模型，我们发现这些火灾燃烧了澳大利亚南部和东部 97,000 平方公里(2) 的植被，这些植被被认为是 832 种本土脊椎动物的栖息地。 70 个类群的大部分 (>30%) 栖息地受到影响；其中 21 种已被列为濒危物种。为了避免物种进一步减少，澳大利亚必须紧急重新评估受火灾影响的物种的灭绝脆弱性，并协助烧毁和未烧毁地区的种群恢复。人口恢复需要采取多管齐下的战略，旨在减轻当前和火灾引起的威胁，包括主动保护未烧毁的栖息地。
Australia's 2019-2020 mega-fires were exacerbated by drought, anthropogenic climate change and existing land-use management. Here, using a combination of remotely sensed data and species distribution models, we found these fires burnt similar to 97,000 km(2) of vegetation across southern and eastern Australia, which is considered habitat for 832 species of native vertebrate fauna. Seventy taxa had a substantial proportion (>30%) of habitat impacted; 21 of these were already listed as threatened with extinction. To avoid further species declines, Australia must urgently reassess the extinction vulnerability of fire-impacted species and assist the recovery of populations in both burnt and unburnt areas. Population recovery requires multipronged strategies aimed at ameliorating current and fire-induced threats, including proactively protecting unburnt habitats.
