  1. Chesapeake Bay Oyster Metrics TEAM reportSTEPHANIE reynolds WESTBY Presentation to Maryland Oyster Advisory Commission May 18, 2011

  2. Oyster Metrics Team: Context • Executive Order 13508: Strategy for Protecting and Restoring the Chesapeake Bay Watershed • Oyster Outcome: • Restore native oyster habitats • and populations • in 20 tributaries by 2025 • Oyster Metrics Team convened by Chesapeake Bay Program Sustainable Fisheries GIT • Goal was defined; • Team was convened by GIT to clarify goal and establish common metrics

  3. Oyster Metrics Team: Charge • Develop common Bay-wide restoration goals, success metrics and monitoring and assessment protocols for the purpose of tracking toward the EO strategy outcome (reef-level and tributary-level) • For sanctuary reefs only • Minimum suite of metrics that should be measured across all sanctuary reefs • Should in no way be seen as limiting additional monitoring and research activity. • As always: adaptive.

  4. Oyster Metrics Team: Charge • Membership: • NOAA (Stephanie Westby) • MD DNR (Eric Weissberger) • VMRC (Jim Wesson) • PRFC ( AC Carpenter) • U.S. Army Corps (Angie Sowers) • VIMS (Mark Luckenbach) • UMCES (Ken Paynter) • Consulting scientists • Science-driven consensus process among the primary governmental agencies involved in oyster restoration in the Bay

  5. Oyster Metrics Team: Approach Reef Level: Trib Level: Ultimate goals of restoration: How it functions over time Functional goals Functional goals Operational goals Operational goals Practical goals: What you plan for; put in the water

  6. Oyster Metrics Team: Goals & Metrics Reef Level: • Stable or increasing spatial extent, reef height and shell budget • Oyster density: • Target: Mean density of 50 oysters/m2 and • 50 grams dry weight /m2 • containing at least two year classes • covering at least 30% of the reef area • Minimum Threshold: Mean density of 15 oysters/m2 and 15 grams dry weight /m2 • containing at least two year classes • covering at least 30% of the reef area

  7. Oyster Metrics Team: Goals & Metrics Trib Level: • Restore, to the reef-level goals, 50 -100% of currently restorable oyster habitat. • Recommend that this be pursued in tributaries for which currently restorable bottom minimally meets the ACOE targets related to the percent of historical bottom (min. of 8% of Yates/ Baylor ground) • Trib size: recommend TNC ‘creek’ and ‘small tributary’ size classifications. • (Recommendation- not a goal)
