Species can be both native and alien to a given administrative region. Here we present the first consolidated inventory of these 'native-alien populations' for South Africa, and provide an overview of the data it contains. To gather data, literature searches were performed and experts were consulted both directly and via an on-line survey. Putative native-alien populations were then scored based on a newly developed protocol. The final inventory contains information on 77 native species from 49 families across nine classes that have formed 132 native-alien populations across the terrestrial, freshwater, and marine environments. The phenomenon is rare when compared to the prevalence of related phenomena, such as alien species introduced from other countries (2033 alien species in South Africa), but is under-reported. However, they pose a specific problem for regulators and managers and their importance will likely increase with global change. These data will be integrated with an existing alien species list and, we hope, will provide a useful foundation to address the issue. We encourage those working on biodiversity to contribute more records.
物种既可以是特定行政区域的本地种，也可以是外来种。在这里，我们首次汇总了南非的这些“本地-外来种群”清单，并概述了其中包含的数据。为了收集数据，我们进行了文献检索，并直接或通过在线调查咨询了专家。然后，根据新制定的方案对假定的本地-外来种群进行评分。最终的清单包含了来自 49 个科的 77 个本地物种的信息，这些物种分布在 9 个纲中，形成了 132 个本地-外来种群，分布在陆地、淡水和海洋环境中。与从其他国家引入的外来物种（南非有 2033 种外来物种）等相关现象相比，这种现象较为罕见，但报告的却很少。然而，它们给监管者和管理者带来了一个特殊的问题，随着全球变化，它们的重要性可能会增加。这些数据将与现有的外来物种清单整合，希望为解决这一问题提供有用的基础。我们鼓励从事生物多样性研究的人员提供更多的记录。
