8%的陆地面积被划为“生物多样性重点区域”（KBAs）。由于这些区域是根据估计存在的所有陆地物种的2%建立的，我们问如果我们用地球上所有的物种来确定额外的KBAs会发生什么。我们利用来自64,110种动植物的数据，在全球范围内探讨了这个问题，以确定在当前标准下有多少地区可以成为KBAs。我们发现，根据空间分辨率的不同，世界陆地面积的26%到68%可以被归类为KBAs。随着评估物种的增加，潜在生物多样性多样性区的总面积急剧增加，这表明如果包括所有物种，几乎所有的陆地表面最终都可以满足成为生物多样性多样性区的生物学要求。此外，密钥管理机构缺乏数据驱动的排名系统，因此假设所有密钥管理机构都同样值得保护。KBAs旨在成为具有生物重要性和可管理的地区，但目前的方法在很大程度上回避了生物组成部分。我们紧急呼吁在KBA方法或替代方法中制定更严格的标准，以确定生物健壮地区的优先次序，帮助确保以证据为基础的投资，并支持实现新的全球生物多样性框架下的目标。
Eight percent of all land surface has been designated as “Key Biodiversity Areas” (KBAs). Since these areas were established based on only two percent of all terrestrial species estimated to exist, we ask what would happen if we used all species on Earth to identify additional KBAs. We explore this question at a global scale by using data from 64,110 species of animals and plants to identify how many areas could qualify as KBAs under current criteria. We find that between 26% and 68% of the world’s terrestrial areas can be classified as KBAs, depending on the spatial resolution. The total area from potential KBAs increases drastically as more species are assessed, suggesting that if all species were included, virtually all land surface could eventually meet the biological requirements for becoming a KBA. In addition, KBAs lack a data-driven ranking system, thus assuming that all KBAs are equally worthy protection. KBAs are intended to be areas which are both of biological importance and manageable but the current approach largely sidesteps the biological component. We make an urgent call for stricter criteria in the KBA methodology or alternative methodologies that allow for biologically robust area prioritization, help secure evidence-based investments, and support progress towards the targets under the new Global Biodiversity Framework.
