Assessment of the Harvest Potential for Sea Ducks Sea Duck Joint Venture, Harvest Management Subcommittee
Background: • In 2010, the Sea Duck Joint Venture canvassed the management community to determine priority information needs for decision-making. • Information to support harvest management decisions was considered to be the most important need.
Purpose of the SDJV Harvest Management Subcommittee: • Further engage with the sea duck harvest management community to determine specific information needed to support decision-making, • Determine what the SDJV research/monitoring programs can do to support those needs, and • Develop recommendations/action items to incorporate into the next SDJV Strategic Plan (2013-17) to support harvest mgmt. information needs.
Participants: • Scott Gilliland (CWS) • Grant Gilchrist (Envir. Canada) • Eric Reed (CWS) • Dan McAuley (USGS) • Brad Allen (ME) • Kelsey Sullivan (ME) • Jay Osenkowski (RI) • Chris Dwyer (FWS R5) SDJV, CTT Members • Paul Padding (FWS) • Ken Richkus (FWS) • Emily Silverman (FWS) • Mark Koneff (FWS) • Barb Avers (MI) • Jim Kelley (FWS) • Don Kraege (WA) • Bob Trost (FWS) • Steve Olson (FWS) • Eric Taylor (FWS R7)
Steps Identified: • Conduct an assessment of the harvest potential for 5 species of sea ducks (black, surf & white-winged scoters, long-tailed ducks and American common eiders) using Potential Biol. Removal • Compile existing demographic information for each species/geographic area • Where demographic information is lacking, obtain expert opinion and agreement on parameters to use in the assessment • Conduct the assessment and provide results for review, discussion and feedback at relevant meetings • Identify and prioritize information gaps for the SDJV to address in support of harvest management decision-making
Discussion Points/Questions: • What survey information should be used to determine Nmin for each species & geographic area?
Discussion Points/Questions: • What source(s) of information should be used to determine Nmin for each species & geographic area? • What sources of information should be used to estimate rmax for each species and geographic area?
Discussion Points/Questions: • Common eider banding has been occurring in the northern portion of the Atlantic Flyway for many years.
Discussion Points/Questions: • Geographic extent of certain populations (American COEI, breeding/wintering LTDU’s)
Proposed Next Steps: • Finish compiling demographic information for black, white-winged and surf scoters (Dec. 2012) • Form species groups that will review information for each of the 5 species and select parameter estimates (Dec. 2012) • Where demographic information is lacking, species groups will obtain expert opinion and agreement on parameters to use in the assessment (Jan. – Feb. 2013) • Conduct the PBR assessment and provide results for review and discussion at relevant flyway meetings (Feb. 2013)
Proposed Next Steps: • Identify and prioritize information needs for the SDJV research & monitoring subcommittee’s to address (Mar. - Jun. 2013) • Report back out to relevant flyways on progress, recommendations and plans for addressing information gaps by the SDJV (July 2013) • Use feedback to update and incorporate priority information needs into the SDJV Implementation Plan & proposal process (July-Aug. 2013) • Provide update on progress, direction, etc. at the next HMWG meeting (Nov. 2013)
