Circles in the sand reveal boating damage to marine biodiversity

The findings of a study by Swansea and Cardiff University scientists highlights the need for boating activities along the UKs beautiful coastlines to be conducted in a more environmentally friendly manner.

Seagrass meadows are an important marine habitat in support of our fisheries and commonly reside in shallow sheltered embayments typical of the locations that provide an attractive option for mooring boats. Research led by scientists at Swansea University provides evidence for how swinging boat moorings have damaged seagrass meadows throughout the UK (and globally) and create lifeless halos within the seagrass. The creation of these halos devoid of seagrass fragments the meadow and reduces its support for important marine biodiversity.

The seagrass Zostera marina (known as eelgrass) is extensive across the northern hemisphere, forming critical fisheries habitat and creating efficient long-term stores of carbon in sediments. This is the first research to have quantified this impact on eelgrass.
