Quantification of mortality rates associated with displacement (QuMR): final report

•In this project we critically reviewed the displacement mortality rates used to determine the mortality of birds displaced by offshore windfarms in the UK. •After reviewing existing information on the displacement mortality rates, running an Expert Elicitation workshop to run elicit mortality rates and using SeabORD predictive model to simulate impacts of displacement and barrier effects, the project concludes: •That the displacement mortality rates generated via expert elicitation and SeabORD/emulation cannot be used within the Displacement Matrix tool currently used in many UK assessments, because of the differences in definition between the alternative approaches.
