人们对欧洲森林生物多样性枯竭和减少的关切促使人们广泛努力改进管理做法。为了衡量这些行动是否成功，对森林生态系统进行适当监测至关重要。多物种指标经常用于评估生物多样性状况及其对已实施管理的反应，但缺乏普遍适用的客观物种选择方法。在这里，我们使用一个基于生态位的方法，以粗略量化物种的资源利用为基础，客观地选择物种纳入泛欧森林鸟类指标。我们确定了实现全面资源覆盖所需的最低物种数量和最敏感物种的组合，并探索了与包含不同物种数量的指标相关的两个关键特征（敏感性和冗余度）之间的权衡。我们将我们的指标与根据专家意见选择的现有森林鸟类指标进行比较，并表明它更能代表更广泛的社区。我们还提出了区域和森林类型具体监测的替代指标，并表明物种的选择可以对指标产生重大影响，并由此预测它所代表的生物多样性的状态。此外，通过比较从目前监测的物种和整个森林鸟类群落中提取的指标集，我们确定了目前监测计划覆盖范围的差距。我们认为，采用这种基于生态位的物种选择框架有助于客观地制定多物种指标，并有很好的潜力扩展到一系列生境和类群。
Concern that European forest biodiversity is depleted and declining has provoked widespread efforts to improve management practices. To gauge the success of these actions, appropriate monitoring of forest ecosystems is paramount. Multi-species indicators are frequently used to assess the state of biodiversity and its response to implemented management, but generally applicable and objective methodologies for species' selection are lacking. Here we use a niche-based approach, underpinned by coarse quantification of species' resource use, to objectively select species for inclusion in a pan-European forest bird indicator. We identify both the minimum number of species required to deliver full resource coverage and the most sensitive species' combination, and explore the trade-off between two key characteristics, sensitivity and redundancy, associated with indicators comprising different numbers of species. We compare our indicator to an existing forest bird indicator selected on the basis of expert opinion and show it is more representative of the wider community. We also present alternative indicators for regional and forest type specific monitoring and show that species' choice can have a significant impact on the indicator and consequent projections about the state of the biodiversity it represents. Furthermore, by comparing indicator sets drawn from currently monitored species and the full forest bird community, we identify gaps in the coverage of the current monitoring scheme. We believe that adopting this niche-based framework for species' selection supports the objective development of multi-species indicators and that it has good potential to be extended to a range of habitats and taxa.
