Description parameter |
The incidental bycatch of harbour porpoises in the International North Sea was estimated at
5974 in 2020, significantly exceeding the threshold value (1622). |
The number of harbour porpoises in the North Sea appears to be increasing slightly. However, the differences in counts are not significant. Nevertheless, it is plausible that the population has not declined since 1994, which means that the good environmental status has been maintained for
criterion D1C2 concerning harbour porpoises. |
An estimated 41300 to 76800 harbor porpoises live in the Dutch part of the North Sea, based on summer counts, which means that the good environmental status has been maintained. Harbor porpoise presence varies throughout the year; in the Dutch North Sea, the highest numbers occur in early spring and lower numbers occur in summer. |
No significant changes have occurred in the geographical distribution of the harbour porpoise. The good environmental status has been maintained. |
The main pressures for marine mammals are known, but there is still little knowledge on precise and especially cumulative effects, causal relationships and ecological preconditions. For this reason, for harbour porpoises D1C5 Habitat condition has been assessed as 'unknown'. |
The incidental bycatch of gray seal meets the threshold value. |
Good environmental status with regard to population size has been maintained for Halichoerus grypus |
No significant changes have occurred in the geographical distribution of the Halichoerus grypus. The good environmental status has been maintained. |
The main pressures for marine mammals are known, but there is still little knowledge on precise and especially cumulative effects, causal relationships and ecological preconditions. For this reason, for grey seal D1C5 Habitat condition has been assessed as 'unknown'. |
Good environmental status with regard to population size has been maintained for Phoca vitulina. |
No significant changes have occurred in the geographical distribution of the Phoca vitulina. The good environmental status has been maintained. |
The main pressures for marine mammals are known, but there is still little knowledge on precise and especially cumulative effects, causal relationships and ecological preconditions. For this reason, for harbour seal D1C5 Habitat condition has been assessed as 'unknown'. |

The integrated assessment of seals is based on information on incidental by-catch (D1C1), population abundance (D1C2), pup production (D1C3) and distributional range (D1C4). Overall, grey seal and harbour seal show an upward trend during this planning period, leading to a positive assessment and good environmental status. It remains necessary to remain alert to the status of seals, however, given the sometimes sudden population trends in the past, and - in the case of the harbour seal - a flattening of the upward trend in the assessment period. There has even been a decline in population growth since 2021. |
