降低生物多样性损失率的全球和区域目标带来了衡量自然状况及其变化方式的必要性。作为回应，已经制定了一些不同的生物多样性指标，这里我们考虑欧洲的鸟类数量指标。鸟类经常被用作生物多样性其他要素的替代品，因为它们是如此广为人知和被广泛研究，而不是因为它们作为环境指标的独特内在价值。然而，在某些情况下，在特定的规模下，鸟类种群的趋势与其他分类群的趋势相关，使其成为有价值的生物多样性指标，并提出适当的警告。在本文中，我们考察了英国和整个欧洲的两个案例研究，在这些案例中，开发了标题鸟类指标，即基于汇总统计的油鸟数量趋势，并将其用于向政策制定者提供信息和帮助。许多欧洲国家和欧洲联盟采用野生鸟类指标作为生物多样性和可持续发展的指标。在讨论中，我们回顾了以这种方式利用鸟类种群的优点和缺点，并展望了这项工作可能如何发展和扩大。
Global and regional targets to reduce the rate of biodiversity loss bring with them the need to measure the state of nature and how it is changing. A number of different biodiversity indicators have been developed in response and here we consider bird population indicators in Europe. Birds are often used as surrogates for other elements of biodiversity because they are so well known and well studied, and not for their unique intrinsic value as environmental indicators. Yet, in certain situations and at particular scales, trends in bird populations correlate with those of other taxa making them a valuable biodiversity indicator with appropriate caveats. In this paper, we look at two case studies, in the UK and Europe as a whole, where headline bird indicators, that is, summary statistics based oil bird population trends, have been developed and used to inform and assist policy makers. Wild bird indicators have been adopted by many European countries and by the European Union as indicators of biodiversity and of sustainable development. In the discussion, we review the strengths and weaknesses of using bird populations in this way, and look forward to how this work might be developed and expanded.
