OSPAR & EcApRHA project approach

Ex: BH1/3 common habitat MSR II (Macoma balthica sandy shallow habitat) Ecological stakes: Application of selection criteria including risk-based approach through BH3/4 and BH1 for biological characteristics Sorry, no VMS yet available at relevant resolution in France. Many thanks to UK for this theoritical illustration of a case study versus physical pressure (sub-type= abrasion ; activity = fishing bottom trawling) = BH3

Assessment scales: 1=predominant habitats (EUNIS 3)= BH3+4

Validation/calibration assessment area of state/pressure relationship Assessment scales: 2=elementary habitats (EUNIS 4-5)= BH2+1

• types. Scale and spatial pattern may vary from meters (stake, beach) to kilometres (bay, gulf),

depending of the type of pressure and habitat distribution and pattern. Monitoring frequencies must be adapted to the ecological and disturbance (pressure) characteristics.
