OSPAR & EcApRHA project approach Assessment scales: - PowerPoint PPT Presentation

OSPAR & EcApRHA project approach Assessment scales: 1=predominant habitats (EUNIS 3)= BH3+4 Ecological stakes: Application of selection criteria Sensitivity/vulnerability matrices including risk-based approach Pres A Pres B Pres C Pres X through Hab 1 BH3/4 and Hab 2 NA BH1 for Hab N biological characteristics Ex: BH1/3 common habitat MSR II ( Macoma balthica sandy shallow habitat) Ground-truthing (state <-> pressure) versus physical pressure (sub-type= abrasion ; activity = fishing bottom trawling) = BH3 =BH2 Sorry, no VMS yet available at relevant resolution in France. Many thanks to UK for this theoritical illustration of a case study

Validation/calibration assessment area of state/pressure relationship Assessment scales: 2=elementary habitats (EUNIS 4-5)= BH2+1 Fig.2: Theoretical principle of an assessment/monitoring area, for specific pressure and habitat 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.

3: feedback to sensitivity characteristics of habitat vs pressure type/intensities Ecological stakes: Application of selection criteria Sensitivity/vulnerability matrices including risk-based approach Pres A Pres B Pres C Pres X through Hab 1 BH3/4 and Hab 2 NA BH1 for Max = L Hab N biological characteristics Ex: BH1/3 common habitat MSR II ( Macoma balthica sandy shallow habitat) versus physical pressure (sub-type= abrasion ; activity = fishing bottom trawling) = BH3 =BH2 Déviation from actual référence state
