  1. SAV Restoration Monitoring Bob Murphy Ecosystem Solutions Becky Thur Chesapeake Research Consortium, Freshwater SAV Partnership

  2. SAV Restoration Monitoring • Need: • More than ten agencies or organizations have been involved in SAV restoration projects baywide since 1997 • Restoration is not limited to one species or type of stock material within species • Restoration is not limited to one methodology • Lessons learned?

  3. SAV Restoration Monitoring What can we learn? • Variability in source materials • Adult plant-based restoration • Laboratory, nursery grown, and field collected -transplanted

  4. SAV Restoration Monitoring What can we learn? • Seed-based restoration • How is it working? • Synthesis of cost-effectiveness

  5. SAV Restoration Monitoring What can we learn? • Site selection • Model validation (MD DNR, Short et al. 2002, others) • Site suitability • Light requirements: Are they stringent enough? • Other physical constraints (wave energy, sediments, etc.)

  6. SAV Restoration Monitoring Why Now? • Department of Defense • Has provided funding for FY 2007 to assess restoration sites at 10 installations covering ~ 12 planting locations in TF, OH, MH, and PH regions of Bay • Potential funding renewal in FY 2008 (leveraging) • Interest from NOAA and ACOE for similar work

  7. SAV Restoration Monitoring What we need from the Workgroup now 1. Methodology Input – standardized metrics • Survival, areal coverage, number of shoots (Fonseca et al. 1998) • Density estimates vs original planting density • Spatial coverage of current bed vs planted • Sediment assessment (% organics, sand/silt ratio, etc.) • Water quality (salinity, DO, Temp, secchi, TSS) • Additional metrics?

  8. SAV Restoration Monitoring What we need from the Workgroup now 2. What are thresholds for “success” or “failure”? • Density compared to original planting • Spatial coverage vs pre-planting • Spatial coverage vs planted area • Presence/absence (is something better than nothing?) • Living resources (fish, invertebrate) colonization • Plant species diversity (in TF, OH, MH) • Consider temporal persistence

  9. SAV Restoration Monitoring What we need from the workgroup for the future of restoration monitoring • Expand to ALL Chesapeake sites (not just DoD) • 10 year historical sites? • Cooperation with active restoration programs • Database of all sites, all sizes • Funding • CBPO • NCBO • ACOE • Others
