1The occurrence of different species of seal (Phocidae) during the Holocene in north‐eastern Europe was influenced by a changing geological situation over the last 12 000 years, characterized by alternating freshwater, brackish and marine stages and by spatially and temporally limited opportunities for migration of marine species into the Baltic basin. The patterns of immigration by ringed sealPhoca hispida, harp sealPhoca groenlandica, grey sealHalichoerus grypusand harbour sealPhoca vitulinaare reviewed here in order to understand present distributions and population sizes. Furthermore, the future of their populations is analysed.2Phoca hispidaimmigrated into the Baltic basin during its brackish Yoldia Stage at the Late Glacial/Early Holocene boundary and has persisted in some disjunct populations until now. A second immigration followed at the beginning of the Littorina Transgression – which resulted in the present stage of the Baltic Sea, obviously caused by the strong cooling event that occurred 6200 calibrated14C years BC. Its present status is not threatened, but global warming will restrict suitable habitat.3Phoca groenlandicahad a mid‐Holocene intermezzo in the Baltic Sea. Its later disappearance was probably caused by hunting of subadult animals by humans.4Halichoerus grypusandPhoca vitulinaalso immigrated at the beginning of the present stage of the Baltic Sea. WhereasH. grypushas been common from this beginning point until modern times, the population ofP. vitulinapersisted at a low level for millennia. Only since the 18th century has its population increased and spread over the whole Baltic Sea.
