Biological invasions are responsible for substantial biodiversity declines as well as high economic losses to society and monetary expenditures associated with the management of these invasions^1,2. The InvaCost database has enabled the generation of a reliable, comprehensive, standardized and easily updatable synthesis of the monetary costs of biological invasions worldwide³. Here we found that the total reported costs of invasions reached a minimum of US$1.288 trillion (2017 US dollars) over the past few decades (1970–2017), with an annual mean cost of US$26.8 billion. Moreover, we estimate that the annual mean cost could reach US$162.7 billion in 2017. These costs remain strongly underestimated and do not show any sign of slowing down, exhibiting a consistent threefold increase per decade. We show that the documented costs are widely distributed and have strong gaps at regional and taxonomic scales, with damage costs being an order of magnitude higher than management expenditures. Research approaches that document the costs of biological invasions need to be further improved. Nonetheless, our findings call for the implementation of consistent management actions and international policy agreements that aim to reduce the burden of invasive alien species.

生物入侵是造成生物多样性大幅下降以及与管理这些入侵^1,2相关的社会和货币支出的高额经济损失的原因。InvaCost 数据库能够生成可靠、全面、标准化且易于更新的全球生物入侵货币成本综合³. 在这里，我们发现过去几十年（1970-2017 年）报告的入侵总成本至少达到 1.288 万亿美元（2017 美元），年平均成本为 268 亿美元。此外，我们估计 2017 年的年平均成本可能达到 1627 亿美元。这些成本仍然被严重低估，并且没有任何放缓的迹象，每十年持续增长三倍。我们表明，记录在案的成本分布广泛，在区域和分类尺度上存在很大差距，损害成本比管理支出高一个数量级。记录生物入侵成本的研究方法需要进一步改进。尽管如此，
