1 Coho Reintroduction in the Upper Columbia: Using Adaptive Management to Achieve Success Fisheries Resource Management Yakama Nation

2 Long Term Vision For Coho Reintroduction “To re-establish naturally spawning coho populations in mid and upper Columbia tributaries to biologically sustainable levels, which provides significant harvest in most years”

3

4 Upper Columbia Tributaries Historical Abundance (Mullan 1983) –Wenatchee: 6,000-7,000 –Entiat: 9,000-13,000 –Methow: 23,000-31,000 Coho Salmon Methow River 1910, Mullan (1992)

5 Project Undertaking: An Uphill Battle Challenges and limitations Identify evaluations needed to study interactions with endemic and sensitive species

6 6 Feasibility Study Goals 1.To determine if a local broodstock could be developed from lower Columbia River stocks 2.Initiate natural production 3.Answer critical uncertainties regarding species interactions.

7 Broodstock Development The Development of a Local Broodstock Wenatchee Basin (Brood Year) 1997: LCR 2000: MCR 1 st Generation 2003: MCR 2 nd Generation 2006: MCR 3 rd Generation 2009: MCR 4 th Generation 1998: LCR 2001: MCR 1 st Generation 2004: MCR 2 nd Generation 2007: MCR 3 rd Generation 2010: MCR 4 th Generation 1999: LCR 2002: LCR & MCR 2005: MCR 1 st & 2 nd Generation 2008: MCR 2 nd & 3 rd Generation 2011: MCR 3th & 4 th Generation

8 Broodstock Development The Development of a Local Broodstock Methow Basin (Brood Year) 1998: LCR 2001: LCR 2004: MCR 1 st Generation 2007: MCR 2 nd Generation 2010: MCR 3 rd Generation 1999: LCR 2002: LCR 2005: MCR 1 st Generation 2008: MCR 2 nd Generation 2011: MCR 3 rd Generation 2000: LCR 2003: LCR & MCR 2006: MCR 1 st & 2 nd Generation 2009: MCR 2 nd & 3 rd Generation

9 Natural Production Wenatchee River Basin 2000-2002 Creating 1 st generation MCR broods 2003-2005 Creating 2 nd generation MCR broods 2006-2008 Creating 3 rd generation MCR broods 2009-2011 Creating 4 th generation MCR broods

10 Natural Production Methow River Basin 2001-2006 Creating 1 st generation MCR broods 2007-2009 Creating 2 nd generation MCR broods 2010-2011 Creating 3 rd generation MCR broods

11 Natural Production Smolt to Adult Return Rates

12 Feasibility Phase Species Interactions Predation Redd superimposition Residualism Competition

13 Feasibility Phase Next Step Create a comprehensive long-term plan for coho reintroduction –Progress brood development towards “preferred habitats” Modeling to determine estimate capacity –Focus on decreasing domestication while increasing population fitness Target PNI > 0.5

14 Proposed Phased Approach An adaptive management strategy to reintroduction Broodstock Development Phases Natural Production Phases

15 Project Performance Indicators Species interactions Adaptability to local conditions Monitoring and Evaluation

16 Program’s Future Several studies being implemented: –Monitor natural origin juvenile freshwater performance Productivity Distribution –Study the rate of divergence between LCR vs MCR Allele frequency over time Phenotypic adaptation –Adult outplant study Relative reproductive success –Measuring phenotypic attributes of upper basin adults at a lower trap facility –Parental Crosses Measure progeny’s adult return rates based on mating schemes

17 Key Milestones March 2010: Final Master Plan completed March 2012: Completed the Final Environmental Impact Statement (FEIS) July 2012: Received a Record of Decision (RoD) from BPA Fall 2012: Revising Biological Assessments (BAs) with USFWS/NMFS to initiate Section 7 consultations Fall 2013: Begin Natural Production Implementation Phase (NPIP) in the Methow subbasin

18 Project Benefits Provide increased cultural and socio-economic value to the region Opportunity to study the local adaptation process and at what rate it can occur Supplying marine nutrients at the onset of winter Increase abundance of a keystone species within ecological communities
