Project Description: In 2010, the Sea Duck Joint Venture (SDJV) identified the need for improved science support for harvest and habitat management of North American sea ducks. In order to prioritize monitoring and research needs in support of harvest management, we applied a Prescribed Take Level (PTL) framework to assess the influence of uncertainty about sea duck demographic parameters on comparisons of observed and allowable harvest estimates. We focused on 7 populations of North American sea ducks: the American subspecies of common eider (Somateria mollissima dresseri), the continental populations of long-tailed duck (Clangula hyemalis) and white-winged scoter (Melanitta fusca), and eastern and western populations of black (M. americana) and surf scoter (M. perspicillata).
