The mortality rate of harbor porpoises as a result of incidental bycatches is lower than the level at which the species is endangered, so that the viability of the species is guaranteed in the long term.

The long-term trend in the percentage of bycatched and stranded harbored porpoises is decreasing.

The 5 year running mean species density is not below the long-term mean annual population size for 5 consecutive years for at least half of the seabird populations.

Positive trend in the number of individuals of thornback ray Raja clavata.

Changes in breeding seabird abundance remain within target limits for 75% of the species monitored (OSPAR EcoQO 2012).

The 90th percentile of chlorophyll a concentration (calculated from March to October, averaged over 6 years) is less than 15 µg/l.

The spatial extent and distribution of the EUNIS level 3 habitats (sandy mud to mud, muddy sands to sands and coarse grained sediments), as well as that of gravel beds fluctuate - relative to the reference state as described in Initial Assessment - within a margin limited to the accuracy of the current distribution maps

The 5 year running mean species density is not below the long-term mean annual population size for 5 consecutive years for minimally half of the non-scavenging seabird species.

The 5 year running mean species density is not above the long-term mean annual population size for 5 consecutive years for minimally two of the scavenging seabird species.

For each of the scavenging seabirds species (Table 2.B), are the mean densities over 5 consecutive years not below the minimum defined by the Birds Directive favourable conservation status.

The yearly number of incidentally bycaught harbour porpoises Phocoena phocoena is less than 1,7 % of the best estimate of the population size.
