  1. 1. Science, Service, Stewardship Nearshore Strategies NOAA RESTORATION CENTER NORTHWEST South Puget Sound Paul R. Cereghino October 2010
  2. 2. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Nearshore Strategies ►Nearshore systems are physically dynamic ►Critical processes operate at large scales ►Strategy responds to whole situation ►Social, Economic and Ecological
  3. 3. NOAA RESTORATION CENTER NORTHWEST Science, Service, Stewardship Nearshore Strategies ►Plan at the scale of physical systems ►Support quest for USACE Construction General ►Facilitate regional project comparisons ►Identify high value sites w/o projects ►Begin integrating protection and restoration PSNERP
  4. 4. NOAA RESTORATION CENTER NORTHWEST Overlapping ‘Sites’ – physiographic process domain River Deltas (2; Nisqually/Deschutes) Coastal Inlets (144; 16-33 High Potential) Barrier Embayment (179; 20-50 High Potential) Beaches (288; 1/3 of all Puget Sound) Science, Service, Stewardship Landform-Based Framework Watershed Influence? DriftCell Influence?
  5. 5. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Degradation Gradient Historic ►Dike and fill wetlands and embayments ►Stabilize eroding shorelines Ongoing ►Cut, scrape and pave watersheds ►Stabilize eroding shorelines ►Spread pollutants
  6. 6. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Degradation Gradient As degradation increases: ►Risk of a threshold change of state increases ►Reliability of restoration decreases, cost increases ►Opportunity for regaining lost services increases ►Strategy for protection or restoration changes Degradation
  7. 7. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Degradation Gradient Varies in character: ►Lost landform ►Shoreline modification ►Nearshore degradation ►Watershed degradation Requires different approach
  8. 8. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Potential Gradient as a site becomes larger, and more complex Quantity, Diversity, or Resilience of ecosystem services increases Potential High Low
  9. 9. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Gradient Analysis Potential Degradation

  17. 17. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST ► South Sound – a shallow mosaic of inlets and embayments – shortest beaches in PS ● Human scaled – stewardship? ► The largest hole – Deschutes/Indian/Moxlie ► Nisqually missing OT/TF component (historically 22.5 ha) Strategy Opportunity
  18. 18. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Strategy Opportunity ► 24 of 51 tentative Puget Sound high potential inlet protection sites ► 33% of the SS watershed flows into Inlet Sites compared to 13% sound-wide ► South Sound has lost 72 barrier embayments in 52 drift cells (typically small; mean of 289 m)
  19. 19. Science, Service, Stewardship NOAA RESTORATION CENTER NORTHWEST Strategy Opportunity ► (always more) Questions ● Sediment system management below scale of drift cell? ● Natural variation in inlet functions among sites? ● Spatial distribution effect on inlet functions? ● Inlet function sensitivity to varied degradation? ● Integration of SMP/regulatory as primary protection for restoration investments?
