  • 100% met the minimum threshold for oyster density (15 oyster per m2 over 30% of the reef area), and 98% met the higher, ideal target density (50 oysters per m2 over 30% of the reef area)
  • 100% met other biological and structural metrics:
    • Multiple year class – Presence of multiple year classes on the reef, as defined by oysters in at least two of the following size classes: market (>76 mm); small (40-75 mm); spat (<40 mm)
