How three tenacious reefs can help restore global oyster populations

Researchers at the University of Sydney have revealed how our oyster reefs can provide lessons on reef restoration projects. More than 85% of naturally occurring oyster reefs have been lost in recent decades due to disease, overharvesting, global warming and pollution. Three reefs that have maintained their oyster populations naturally are in New South Wales, Australia: Gamay (Botany Bay), Port Hacking and Crookhaven (on the Shoalhaven).
