Project Description: In 2010, the Sea Duck Joint Venture identified the need for improved science support for harvest and habitat management of North American sea ducks. 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 for seven populations of North American sea ducks.
