Revising Harvest Protocols for Sandy & Clackamas Coho Populations

Revising harvest management guidelines for Sandy & Clackamas coho populations considering new data. This project aims to establish appropriate harvesting levels in relation to recovery targets with a focus on weaker populations. The goal is to propose revised harvest strategies for PFMC review and adoption by October 2013.

Presentation Transcript

  1. Background • Historic data sets are really only available for Sandy and Clackamas. • Current harvest management uses these populations as drivers, but we know that the Clackamas in particular is one of the healthier populations we have. • Conservative harvest rates implemented due to uncertainty in how Sandy/Clackamas relate to other LCR populations.

  2. Reinitiate consultation on the current LCR • coho harvest BiOp • What new info is available for LCR pops. • Full seeding levels • What levels are appropriate • Relationship to target abundances in Recovery Plan • Develop for other populations • Propose revised harvest matrix • Account for weaker strata/populations (similar to OCN) • Add coastal strata (Or/Wa), Washington Cascades • Includes risk assessment

  3. Completed or Mostly Completed • Data for Oregon and Washington completed. • Productivity parameters updated. • Derived estimates of “full-seeding” for populations. • Constructed revised PVA model structure.

  4. Next Steps • Conduct risk assessments. • Test various harvest matrix and structures. (Rinse and repeat) • Prepare final proposal and submit to NOAA. • Goal is final review/adoption by PFMC in October 2013.
