Core indicators for Biodiversity

Population growth rates, abundance and distribution of marine mammals

Pregnancy rates of marine mammalsNutritional status of sealsNumber of drowned mammals and waterbirds in fishing gears

What core indicators do we have?

Pre-core indicators for BiodiversityNumber of waterbirds being oiled annuallyLower depth distribution limit of macrophyte speciesCumulative impact on benthic habitatsExtent and distribution of benthic biotopes

CORESET II 2013-2015Strengthening the GES boundaries, harbour porpoise abundance, databaseMonitoring of offshore spp., coherence of monitoring methods, GES boundaries

Pelagic fish community

Improved co-operation, macrophyte team, offshore BQI, biotope indicators.

Validation of GES boundaries

Waiting for the port surveys!

Web-placed core indicator reports to be launched in the autumn

2013!
