维多利亚州政府隐瞒超过12个月的一份报告显示，该州考拉种群面临严重的健康危机。1 由阿瑟·赖拉研究所与主要大学科学家联合完成的报告于2025年6月完成，本周三才被公开。1 根据调查，维多利亚州考拉种群数量为217,000至224,800只，远低于之前估计的460,000只。1
健康评估揭示了广泛存在的疾病问题。1 研究人员对68只考拉进行的评估中，29只（占43%）因健康状况不佳而被安乐死。1 被安乐死的考拉更可能患有毛发状况差、牙齿疾病和尿路感染等疾病，其中绝大多数尿路感染由衣原体引起。1 整体而言，37%的维多利亚州考拉存在牙齿疾病。1 报告作者、野生动物兽医莱安妮·威克表示："我们在维多利亚州的考拉种群中面临危机，因为我们有非常令人担忧的健康和福利水平。"1
此外，考拉的栖息地状况也令人担忧。1 23%的维多利亚州考拉种群现在生活在蓝桉树种植园中，这些地区的考拉密度远高于本地森林。1 为应对这一局面，环境部长杰克琳·赛姆斯宣布投入260万澳元用于考拉保护和栖息地修复工作。1
A report completed in June 2025 but withheld by the Victorian government for over twelve months has exposed severe health deterioration and a dramatically lower population count among the state's koalas than previously believed 1. The survey, conducted by the Arthur Rylah Institute for Environmental Research in collaboration with leading university scientists, estimates Victoria's koala population at between 217,000 and 224,800 individuals 1—less than half the previously estimated 460,000 1.
Health assessments of 68 koalas revealed widespread disease and suffering across the population 1. Twenty-nine of these animals, representing 43 percent, were euthanized due to poor welfare conditions 1. Tooth disease affects 37 percent of Victoria's koalas, while those euthanized showed markedly higher rates of poor fur condition, dental disease, and urinary tract infections, predominantly caused by chlamydia 1. The situation is compounded by habitat pressures: 23 percent of the state's koala population now lives in blue gum plantations, where population density significantly exceeds that found in native forests 1.
The Victorian government announced the funding allocation on Wednesday, committing 2.6 million Australian dollars to koala protection and habitat restoration 1. Leanne Wicks, a wildlife veterinarian and report author, characterized the findings starkly: "We are facing a crisis in Victoria's koala population because we have very concerning health and welfare levels" 1.
