Want to restore oyster reefs? Find a site where they don't wash away or become buried under the sand

Phys · · 484 words · By Royal Netherlands Institute

New research indicates that restoring oyster reefs in temperate marginal seas, such as the North Sea, requires considering short-term physical disturbances like sediment burial and strong currents. Scientists found that oysters kept above the seabed survived well in experiments, whereas those on the soft seabed were vulnerable to dislodgement or burial. The study advises that restoration planning must adopt a risk-informed strategy based on these physical dynamics.
