The Seal and Sea Eagle subprogram (Table 4, #8.2.6) monitors marine top consumers as indicator species to assess harmful effects of environmental toxics. Hopefully, in the long run, the program will show that these species have natural reproduction, health, and population. At present the subprogram has no sampling network. In the Bothnian Bay, the Swedish Museum of Natural History (NRM) monitors grey seals, ringed seals, and European sea eagles. These observations will show the state and trends of population size, development, and health of seals and of reproduction, population size, and development of European sea eagles. The aim of early warning is to detect changes in reproduction, health, survival, and population trends that may result from changes in the marine environment.
