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.

Fitting statistical distributions to seaduck count data: Implications for survey design and abundance estimation

Determining appropriate statistical distributions for modeling animal count data is important for accurate estimation of abundance,distribution,and trends.In the case of
seaducks along the U.S.Atlantic coast,managers want to estimate local and regional abundance to detect and track population declines, to define

SDJV Implementation Plan 2011-2014

At the inception of the SDJV, the lack of understanding about population delineation was seen as one of the highest priority topics for future work; this priority was confirmed during a 2010 review of program direction. Identifying links among breeding, molting, staging, and wintering areas will help improve the design of monitoring surveys and interpretation of trends, and more effectively direct management actions.

Sea Duck Joint Venture Strategic Plan 2008-2012

The fifteen species of sea ducks (Tribe Mergini) are the most poorly understood group of waterfowl in North America. The most basic biological information is unknown for some species. Few species have reliable population indices or estimates of annual productivity, and much of our knowledge is based on a very few, localized studies. Also, current survey design is unable to accurately estimate sea duck harvest.

Recommendations for Establishing Population Objectives for Sea Ducks

No population objectives are listed for any sea duck population in the most recent (2004) update
or earlier versions of the Plan. The primary reason for lack of sea duck objectives is a lack of
reliable abundance estimates, confounded by inadequate knowledge of sea duck distribution for
some species.
Following a 2008 SDJV progress report to the NAWMP Plan Committee, the PC acknowledged
the need to establish population objectives for sea ducks and stated that this need should be
