Biodiversity common indicators

The common indicators agreed by OSPAR for assessing the status of biodiversity in the North-East Atlantic cover marine mammals, seabirds, fish communities, seafloor habitats, pelagic habitats, non-indigenous species and food webs.

The biodiversity common indicators contributed assessments of the status biodiversity in the North-East Atlantic to the OSPAR Intermediate Assessment 2017. The assessments are published in the OSPAR Assessment Portal.

The indicators are based on information from monitoring programmes described in the Coordinated Environment Monitoring Programme (CEMP). The programmes are described in the Appendices to the CEMP Agreement. Detailed descriptions, including method descriptions for the indicator calculations, are included in the CEMP Guideline Agreements.
