| Summary: | The data file associated with Figure 1b provides population data from the Kattegat-Skagerack harbour seal (Phoca vitulina). Historical data are reconstructed based on bounty statistics (1). Data from 1970 are based on systematic annual surveys (2,3,4). Projections beyond 2023 are hypothetical illustrations of potential population developments inspired by a population projection model (3). 1 Heide-Jørgensen, M.-P., and Härkönen, T. J. (1988).
