The seagrass Posidonia oceanica is extensively monitored in Mediterranean coastal waters and is an ideal candidate for an eco-regional assessment of the coastal ecosystem. The aim of this study is to evaluate the potential of P. oceanica as eco-regional indicator for its assessment at the scale of Mediterranean basin. For this purpose, regional and national P. oceanica monitoring programmes are identified, and their data and metadata are collected and compared in terms of objectives, strategies, sampling designs and sampling methods. The analysis identifies a number of issues concerning data quality, reliability and comparability. In particular, the adoption of different sampling designs and methods may introduce relevant errors when comparing data. The results of this study stress the necessity of carefully planning monitoring programmes. Moreover, it highlights that the adoption of a number of common tools would facilitate all Mediterranean monitoring activities and allows an optimisation of management efforts at an eco-regional scale.
地中海沿海海域广泛监测海草波西多尼亚海草，它是进行沿海生态系统生态区域评估的理想候选物种。本研究旨在评估海草波西多尼亚海草作为生态区域指标的潜力，以便在地中海盆地范围内对其进行评估。为此，确定了区域和国家的波西多尼亚海草监测计划，并收集和比较其数据和元数据，重点是目标、策略、采样设计和采样方法。分析确定了数据质量、可靠性和可比性方面的一些问题。特别是，在比较数据时，采用不同的采样设计和方法可能会引入相关误差。本研究的结果强调了仔细规划监测计划的必要性。此外，它还强调采用一些共同的工具将有助于所有地中海监测活动，并允许在生态区域范围内优化管理工作。
