生物多样性需要时间基线，以便衡量生物多样性随时间的变化，确定生物多样性养护目标，评价养护进展。有限的生物多样性信息被广泛认为是确定时间基线的一个主要障碍，尽管缺乏对此的全面定量评估。在这里，我们报告的时间基线，可以从欧洲的生物多样性监测计划，并比较那些重要的人为压力的上升。大多数生物多样性监测计划都是在20世纪末启动的，那时人类造成的压力已经达到目前的一半。因此，根据生物多样性监测数据确定时间基线会低估主要人为压力的全面影响。此外，分类群和组织水平之间的偏差提供了一个截断的生物多样性随着时间的推移。在设计管理战略和政策时，需要明确承认这些限制，因为它们严重限制了我们确定旨在恢复或扭转生物多样性损失的相关养护目标的能力。我们讨论了需要额外的研究工作超出标准的生物多样性监测重建主要人为压力的影响，并确定有意义的生物多样性的时间基线。
Temporal baselines are needed for biodiversity, in order for the change in biodiversity to be measured over time, the targets for biodiversity conservation to be defined and conservation progress to be evaluated. Limited biodiversity information is widely recognized as a major barrier for identifying temporal baselines, although a comprehensive quantitative assessment of this is lacking. Here, we report on the temporal baselines that could be drawn from biodiversity monitoring schemes in Europe and compare those with the rise of important anthropogenic pressures. Most biodiversity monitoring schemes were initiated late in the 20thcentury, well after anthropogenic pressures had already reached half of their current magnitude. Setting temporal baselines from biodiversity monitoring data would therefore underestimate the full range of impacts of major anthropogenic pressures. In addition, biases among taxa and organization levels provide a truncated picture of biodiversity over time. These limitations need to be explicitly acknowledged when designing management strategies and policies as they seriously constrain our ability to identify relevant conservation targets aimed at restoring or reversing biodiversity losses. We discuss the need for additional research efforts beyond standard biodiversity monitoring to reconstruct the impacts of major anthropogenic pressures and to identify meaningful temporal baselines for biodiversity.
