Recently, the science and policy agenda on biodiversity moved to include ecosystem services assessments and it is recognised that for determining the effectiveness and progress of policy frameworks monitoring is crucial. Within European monitoring schemes, data is collected following different sampling protocols for a range of biodiversity or context related aspects; from EU-wide general land cover mapping to red list species within Annex I habitats. In this paper, we analysed field instructions of seven monitoring schemes on the extent to which they can provide data on the provision of ecosystem services and what additional information may be needed for future monitoring of ecosystem services. We compared seven monitoring schemes (i.e. CORINE Land Cover, Land Use Cover Area Survey (LUCAS), European Biodiversity Observation Network (EBONE), biodiversity monitoring on organic and low-input farming systems (BioBio), National Inventory of the Landscape of Sweden (NILS) and Pan-European Common Birds Monitoring (PECBM) and UK Butterfly monitoring (UK-BM)) by scoring the quality of recorded parameters and the adequacy of sampling protocols for ecosystem service monitoring. All the examined schemes were able to provide some parameters on ecosystem services, but the quality of the parameters on average did not exceed the level of qualitative data. Additionally, the divergence between the sampling designs of the schemes and the spatial characteristics of ecosystem services reduced the potential monitoring value of all schemes. Monitoring schemes including a range of sampling methods, scales and included the recording of data on habitats, such as EBONE, BioBio and NILS, provided the best data on the provision of ecosystem services. We conclude that improvement of the monitoring of ecosystem services is hindered by several knowledge gaps: (1) a robust definition and conceptual framework of ecosystem services; (2) the linkage between biodiversity and ecosystem services; and (3) the interpretation of monitoring data. In addition to ecosystem service monitoring, biodiversity monitoring unremittingly remains very important, at least to identify trade-offs between the management for services and the resulting biodiversity status.
