OSPAR's Quality Status Report 2023 Friday Ocean Findings Week 10
The complex coastlines of the North-East Atlantic shape life beneath the waves. Altering the seabed around them and creating places for others to thrive, Week 10 of #FridayOceanFindings looks at the latest assessments for two of the habitats that are on OSPAR's list of threatened and/or declining habitats.

The status of the European flat oyster is still critical in the North-East Atlantic, although restoration efforts exist. Key pressures like fisheries, habitat damage, introduction and further distribution of non-indigenous species or diseases/pathogens still pose a significant threat to oyster beds.

Although measures are in place in some countries, Maerl beds continue to be threatened in the North-East Atlantic and are impacted by extraction, fishing, mariculture, dredging, climate change and the introduction of non-indigenous species.

These assessments are components of OSPAR’s Quality Status Report (QSR) 2023. The QSR will examine the current state of the marine environment and ecosystems, and the human activities benefiting from the marine environment and interacting with it.

We hope you enjoy these reports. Please do contact us with any comments at [email protected]
