澳大利亚研究人员在2019-20年黑夏大火后对桉树林进行了调查。1那场大火烧毁了澳大利亚东部约700万公顷的桉树林。1研究发现，不同环境条件下的桉树林表现出明显差异：生长在湿润肥沃土壤中的大型老树受灾最严重，而干旱贫瘠土壤地区的森林韧性更强，损失相对较少。1
澳大利亚已知有800多个桉树物种。1研究表明，在气候范围干旱边缘生长的某些物种面临更高风险，其中Eucalyptus dalrympleana和Eucalyptus radiata在气候范围干旱端出现了更高的死亡率。1气候变化可能导致类似的干旱条件变得更加频繁，威胁这些物种的长期生存能力。1
Australian researchers investigating eucalypt forests following the catastrophic 2019-20 Black Summer bushfires have identified stark differences in fire vulnerability across species and growing conditions. The fires destroyed approximately 7 million hectares of eucalypt forest in eastern Australia 1, yet recovery patterns reveal a troubling picture for certain tree populations as climate pressures intensify.
The research found that large, mature trees growing in moist, fertile soils suffered disproportionate losses compared to forests in drier, nutrient-poor regions, which demonstrated greater resilience 1. Among Australia's more than 800 known eucalypt species 1, certain varieties face heightened risk. Species such as Eucalyptus dalrympleana and Eucalyptus radiata, which occur at the arid margins of their climate ranges, exhibited elevated mortality rates 1. As climate change may make such conditions more frequent, some eucalypt populations may struggle to survive the intensifying fire regimes they will encounter 1.
