Indicators for status assessment of species, relevant to MSFD Biodiversity Descriptor
Identifying methods to set thresholds for the GES assessment
The inconsistency in the determination of the Good Environmental Status for species assessment under the first cycle of the EU’s Marine Strategy Framework Directive emerged a harmonisation exercise. This exercise was launched with the species’ identification of MSFD Descriptor’s 1 concern and the collection of the operational or developing indicators and methods for the status assessment and classification of marine species. The latter was materialised with this report, by collecting information from several sources including the Regional Sea Conventions and the relevant marine and environment EU policies. The methodological standards and the threshold setting processes can be harmonised at three levels, to achieve consistent GES determination for the species assessed under the MSFD: i) MSFD criteria; ii) species groups, and iii) spatial scale. The next step will be to further evaluate the operability and suitability of these indicators and methods, associate them with data availability and propose the best possible option for the status classification of species at those three levels.
