This core indicator evaluates the status of the marine environment based on the reproductive status of seals in the Baltic Sea. Quantitative thresholds are used to evaluate if core indicators status is Achieve, Fail or Not assessed. Good status is achieved when the annual reproductive rate (i.e. pregnancy/birth rate) is at least 90% for five years and older (harbour seals) and six years and older (grey and ringed seals).
Currently, a full status evaluation has only been carried out for the grey seal based on Finish and Swedish data. The indicator is applicable for all species of seals and marine mammals that occur in the Baltic Sea, however the amount of data have so far been insufficient for an evaluation of other marine mammal species.
This dataset displays the result of the indicator in HELCOM Assessment Scale 1 (Whole Baltic).
