The Yealm - Pacific oyster survey

South Devon Estuaries volunteer survey of feral Pacific oyster populations

It’s difficult to be positive about Invasive Non-Native Species (INNS) and especially with marine INNS, it is nearly all about prevention rather than cure. And necessarily, with many unknowns, we have to take a precautionary approach to how damaging INNS can be.

One INNS that is sometimes proving to be a particular nuisance when conditions are ‘right’ are feral Pacific oysters. On a few beaches around the Southwest, these oysters have settled on mass, completely smothering the beach with shells sharp enough to ribbon-cut the unwary.

Can you help

In partnership with Natural England, we are setting up a number of local volunteer groups to help us survey the populations and density of the feral Pacific oysters along the shores of our local estuaries in particular and are seeking more volunteers to help us.
