DESCRIPTION

Supplementary Table S1: The direct, global assessment of the condition of native oyster reefs from records of reef abundance and their harvest shows that in most of 144 bays in 40 ecoregions the condition of these ecosystems is poor overall . While individual oysters are still present in most places, records of historical (past 20 to ~130 years) and recent abundances show that reefs that were once common are now often rare or extinct as ecosystems. Oyster reefs are at <10% of prior abundance in most bays (70%) and ecoregions (63%). They are functionally extinct, in that they lack any significant ecosystem role with <1% of prior abundances remaining in many bays (37%) and ecoregions (28%), particularly in North America, Australia and Europe. Very few bays and ecoregions are rated in good condition (>50% of reefs remaining).
