The understanding of ecosystem services is essential to support sustainable use and preservation of ecosystems. Coralligenous habitats, main contributors of the Mediterranean marine biodiversity, are yet understudied in term of services provided. This study presents an original small-scale approach to investigate the services provided by coralligenous habitats of a French study area consisting of two marine sites (Marseille and Port-Cros sites) in order to cover two contrasted anthropogenic pressure despite the small-scale. Our results are based on the opinions of 43 experts who ranked 15 services in terms of existence and level of importance for human well-being: supporting ecological functions were considered the most important, then provisioning and cultural services. Regulating services were considered uncertain due to a lack of knowledge. The small-scale approach highlighted a need for a referential frame to determine the existence of services (e.g. geographical and temporal scales, benefits and beneficiaries levels).
对生态系统服务的理解对于支持生态系统的可持续利用和保护至关重要。珊瑚礁生境是地中海海洋生物多样性的主要贡献者，但就其所提供的服务而言，研究还很不足。本研究提出了一种原始的小规模方法，以调查法国两个海洋地点（马赛和科克港地点）的珊瑚礁生境所提供的服务，以覆盖尽管规模较小但存在的两种截然不同的人为压力。我们的结果基于 43 位专家的意见，他们根据存在和对人类福祉的重要性对 15 项服务进行了排名：支持生态功能被认为是最重要的，其次是供应和文化服务。由于知识的缺乏，调节服务被认为是不确定的。小规模方法强调需要参考框架来确定服务的存在（例如地理和时间尺度、利益和受益人的水平）。
