Implications of Demographic Uncertainty for Harvest Management of North American Sea Ducks

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

Sea Duck Joint Venture Implementation Plan 201 5 - 201 7

PRIORITIES 2015–2017 Priorities set out in this Implementation Plan are designed to help meet the SDJV mission,
which is to “...promote the conservation of all North American sea ducks through partnerships by providing greater
knowledge and understanding for effective management.”
The 2014-2018strategic plan reflects a significant shift in focus for the SDJV, from a broad-based science program
to a more focused program intended to provide information most needed by managers to make informed

Sea Duck Joint Venture Strategic Communications Plan 2015-2019

The mission of the Sea Duck Joint Venture(SDJV)is to promote the conservation of North American sea ducks through partnerships by providing greater knowledge
and understanding for effective management. SDJV focuses on the 15 species of North American sea ducks on their coastal water habitat for migration and wintering as well as boreal forest and tundra habitat for nesting. Since the JV’s founding in 1998, the four pillars of its work have included science, communications, funding, and conservation.

Population Ecology of Pacific Common Eiders on the Yukon Kuskokwim Delta, Alaska

Knowledge of ecological factors that influence birth, death, immigration, and emigration provide
insight into natural selection and population dynamics. Populations of Pacific common eiders
(Somateria mollissima v-nigrum) on the Yukon-Kuskokwim Delta (YKD) in western Alaska declined by
50-90% from 1957 to 1992 and then stabilized at reduced numbers from the early 1990’s to the
present. This study investigates the primary underlying processes affecting population dynamics of
