Continental-scale shellfish reef restoration in Australia

Shellfish reef ecosystems in Australia have been greatly depleted. Building on earlier trials, a continent-scale restoration initiative was underway by 2019 to restore 30% of their former distribution. Integral elements of building and progressing this ecoscape-scale restoration program are outlined and challenges discussed. Documenting pathways and challenges to large-scale restoration informs global commitments to see 30% of degraded ecosystems under effective restoration by 2030.
