Principal Investigator (PI): Dan Rosenberg (Alaska Department of Fish & Game)

Managing Agency: ADFG

Assisting Personnel: Mike Petrula

Research Location: Prince William Sound

Restoration Category: Monitoring

Injured Resources Addressed: Harlequin Ducks

Abstract: Harlequin duck populations have not recovered from injuries sustained from the oil spill. Proposed surveys are designed to assess the extent of recovery of ducks inhabiting oiled areas and determine if low reproductive success has resulted in changes in population structure and productivity that may limit recovery. Shoreline boat surveys will be used to compare population age and sex structure, distribution, abundance, and productivity between oiled and unoiled areas in Prince William Sound in late-winter, spring, and late-summer. Changes in population size, structure, and production in oiled and unoiled areas within and between years will be compared. Continued population monitoring and brood surveys will allow us to assess trends and suggest factors limiting recovery.
