Harvest:

In some areas of North America recreational hunting of sea ducks is increasing, and sea ducks comprise a major component of subsistence harvest across the North. Current harvest surveys and studies do not adequately measure the harvest of sea ducks or allow assessment of harvest impacts on specific populations. Discussion topics in this workshop may include: (1) the historical and current extent of sea duck hunting (sport and subsistence); (2) methods to improve the accuracy and extent of harvest data collection; (3) assessment of harvest in the context of population models (e.g., K-select species, site fidelity, age-related effects); (4) management paradigms for diverse public uses; and (5) integrating management of subsistence and recreational harvests.

Satellite Telemetry:

Satellite telemetry has become a valuable tool in sea duck research to link populations in breeding and wintering areas, as well as to examine migration routes and chronology. The goal of this workshop will be to discuss (1) problems and advances in the technology, (2) integration of results, and (3) potential future research applications. Session speakers will provide examples of research results from different species on both coasts, summarize past and ongoing projects, compile a list of transmitter vendors and options, recommend techniques to optimize use of the Argos system, and discuss research applications and analyses.

Contaminants/Disease :

Although populations of several species of sea ducks have declined in recent years, little is known about the specific causes of these declines. Contaminants and diseases are two broad categories of factors that could have potential effects on sea duck populations. This workshop will address some of the current research on contaminants and disease and priorities for the future. Specific topics will include trace elements and metals, the effects of oil exposure, the potential for emerging diseases (such as West Nile Virus) to affect sea ducks, and concerns related to avian influenza.

Offshore and Nearshore Wind Facilities -- Seaduck Impacts:
(Workshop Powerpoint Presentations on Wind Turbines--New! Icon)

The impacts of near- and offshore "wind farms" are of growing concern in U.S. waters, the Great Lakes, and coastal areas as the Army Corps of Engineers currently has pending applications for more than 1,000 wind turbines in East Coast waters alone. Impacts range from direct mortality to habitat fragmentation and seaduck disturbance. This panel will review the status of European offshore studies, assess findings as they relate to potential impacts in U.S. waters, review trust agency responsibilities, discuss options for sharing information, and review partnerships with industry and their consultants.
