In the face of unprecedented global biodiversity loss, conservation planning must balance between refining and deepening knowledge versus acting on current information to preserve species and communities. Phylogenetic diversity (PD), a biodiversity measure that takes into account the evolutionary relationships between species, is arguably a more meaningful measure of biodiversity than species diversity, but cannot yet be applied to conservation planning for the majority of taxa for which phylogenetic trees have not yet been developed. Here, we investigate how the quality of data on the taxonomy and/or phylogeny of species affects the results of spatial conservation planning in terms of the representation of overall mammalian PD. The results show that the better the quality of the biodiversity data the better they can serve as a basis for conservation planning. However, decisions based on incomplete data are remarkably robust across different levels of degrading quality concerning the description of new species and the availability of phylogenetic information. Thus, given the level of urgency and the need for action, conservation planning can safely make use of the best available systematic data, limited as these data may be.
面对前所未有的全球生物多样性丧失，保护规划必须在完善和深化知识与利用现有信息保护物种和群落之间取得平衡。系统发育多样性（PD）是一种考虑物种之间进化关系的生物多样性衡量标准，可以说是比物种多样性更有意义的衡量标准，但对于大多数尚未建立系统发育树的分类群，它还不能应用于保护规划。在这里，我们研究了物种分类学和/或系统发育数据的质量如何影响空间保护规划的结果，具体表现为整体哺乳动物 PD 的代表性。结果表明，生物多样性数据的质量越好，它们就越能为保护规划提供更好的基础。然而，基于不完整数据做出的决策在描述新物种和提供系统发育信息的质量下降方面具有很强的稳健性。因此，鉴于紧迫性和行动的必要性，保护规划可以安全地利用现有的最佳系统数据，尽管这些数据可能有限。
