N2 - We assessed the sensitivity of harbour seal (Phoca vitulina), grey seal (Halichoerus grypus), and harbour porpoise (Phocoena phocoena) populations to offshore wind farms in Danish waters. Sensitivity was defined as the relative abundance of a species, multiplied by the consequence of constructing a wind farm in a given area, where we considered consequences across both construction and operation of the wind farms. Consequences were assessed based on published studies and expert knowledge. The division of the resulting sensitivity maps into areas where sensitivity is highest, medium and lowest also corresponds to areas where offshore wind farms are expected to have relatively high or low impacts on the population.
