The Convention on Biological Diversity (CBD) emphasises the role of biodiversity in delivering benefits essential for all people and, as a result, seeks to safeguard all life-forms. The indices that are used to measure progress towards international conservation and sustainability goals, however, focus solely on the 'native' component of biodiversity. A subset of non-native species can cause undesirable economic, social, or biological effects. But non-native species also contribute to regional biodiversity (species richness and biotic interactions) and ecosystem services. In some regions and cities, non-native species make up more than half of all species. Currently, the contributions of these species to biodiversity and ecosystem services are overlooked. Here, I argue that biodiversity and sustainability indices should include all species. This is not only consistent with definitions of biodiversity but also will promote the idea that long-term, sustainable, human well-being is intricately tied to benefits derived from nature.
《生物多样性公约》（CBD）强调了生物多样性在为所有人提供必要利益方面的作用，因此，它力求保护所有生命形式。然而，用于衡量国际保护和可持续性目标进展的指标仅关注生物多样性的“本地”组成部分。非本地物种的一个子集可能会造成不良的经济、社会或生物影响。但是，非本地物种也有助于区域生物多样性（物种丰富度和生物相互作用）和生态系统服务。在一些地区和城市，非本地物种占所有物种的一半以上。目前，这些物种对生物多样性和生态系统服务的贡献被忽视了。在这里，我认为生物多样性和可持续性指数应包括所有物种。这不仅与生物多样性的定义一致，而且还将促进这样一种观念，即长期、可持续的人类福祉与从自然中获得的利益密切相关。
