Background South America hosts some of the world’s most prominent biodiversity hotspots. Yet, Uruguay – a country where multiple major ecosystems converge – ranks amongst the countries with the lowest levels of available digital biodiversity data in the continent. Such prevalent data scarcity has significantly undermined our ability to progress towards evidence-based conservation actions – a critical limitation for a country with a strong focus on agricultural industries and only 1.3% of the land surface guarded by protected areas. Under today’s rapid biodiversity loss and environmental changes, the need for open-access biodiversity data is more pressing than ever before. To address this national issue, Biodiversidata – Uruguay’s first Consortium of Biodiversity Data – has recently emerged with the aim of assembling a constantly growing database for the biodiversity of this country. While the first phase of the project targeted vertebrate biodiversity, the second phase presented in this paper spans the biodiversity of plants. New information As part of the second phase of the Biodiversidata initiative, we present the first comprehensive open-access species-level database of the vascular plant diversity recorded in Uruguay to date (i.e. all species for which data are currently available and species presence has been confirmed). It contains 12,470 occurrence records from across 1,648 species and 160 families, which roughly represents 60% of the total recorded flora of Uruguay. The primary biodiversity data include extant native and introduced species from the lycophytes, ferns, gymnosperms and angiosperms groups. Records were collated from multiple sources, including data available in peer-reviewed scientific literature, institutional scientific collections and datasets contributed by members of the Biodiversidata initiative.

Biodiversidata：乌拉圭维管植物物种多样性的新数据集

背景 南美洲拥有一些世界上最著名的生物多样性热点。然而，乌拉圭——一个拥有多个主要生态系统的国家——是非洲大陆可用数字生物多样性数据水平最低的国家之一。这种普遍存在的数据稀缺性极大地削弱了我们在循证保护行动方面取得进展的能力——对于一个高度重视农业且只有 1.3% 的土地表面被保护区保护的国家来说，这是一个严重的限制。在当今生物多样性迅速丧失和环境变化迅速的情况下，对开放获取生物多样性数据的需求比以往任何时候都更加紧迫。为了解决这个国家问题，Biodiversidata——乌拉圭的第一个生物多样性数据联盟——最近出现，旨在为该国的生物多样性建立一个不断增长的数据库。虽然该项目的第一阶段针对脊椎动物的生物多样性，但本文介绍的第二阶段涵盖了植物的生物多样性。新信息 作为 Biodiversidata 倡议第二阶段的一部分，我们展示了迄今为止乌拉圭记录的第一个全面的开放获取的物种级维管植物多样性数据库（即，当前可获得数据且物种存在的所有物种确认的）。它包含来自 1,648 个物种和 160 个科的 12,470 个发生记录，大约占乌拉圭记录的植物群总数的 60%。主要的生物多样性数据包括来自石松植物、蕨类植物、裸子植物和被子植物群的现存本地和引进物种。记录来自多个来源，包括同行评审的科学文献中可用的数据、机构科学收藏和生物多样性倡议成员提供的数据集。完整的数据库可以在 Zenodo 存储库中访问：doi.org/10.5281/zenodo.3954406
