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

Restoring once abundant oyster reefs in temperate marginal seas such as the North Sea is a challenging task. New research by NIOZ marine ecologist Zhiyuan Zhao and colleagues shows that it is necessary to consider the short-term risk that introduced oysters will become buried by shifting sediment or will be dislodged by strong near-bed currents. For restoration success, these short-term physical disturbances can be more decisive than longer-term water-quality conditions. The results of pioneering experiments at 32 m depth, were published today in One Earth.
