Basin-scale distribution of harbour porpoises in the Baltic Sea provides basis for effective conservation actions
Knowledge on spatial and seasonal distribution of species is crucial when designing protected areas and implementing management actions. The Baltic Proper harbour porpoise (Phocoena phocoena) population is critically endangered, and its distribution is virtually unknown. Here, we used passive acoust...

During the reproductive season, two main areas of high probability of porpoise detection were identified.
