New bid to protect Bay's precious seagrass

Three brand new boat moorings designed to protect Tor Bay’s seagrass meadows have been installed at Fishcombe Cove - the first of their kind in Tor Bay.

Wild Planet Trust has installed the mooring buoys as part of the #SaveOurSeagrass campaign established in 2018. The campaign has been supported by Totnes-based underwater measuring instrument manufacturer, Valeport. Along with other funders, this support has also enabled a dedicated group of volunteer divers to monitor the Tor Bay seagrass beds to determine the best place for moorings and survey the health of our seagrass.

The meadows in Tor Bay are a vital nursery bed for young fish and home to both the UK seahorse species , the spiny and short-snouted seahorse. Shallow, sheltered coastal bays provide ideal conditions for the growth of seagrass meadows, but for this reason they are also attractive mooring and anchorage sites for boating communities.

Both boat anchors and traditional mooring systems have a detrimental impact on seagrass. Anchors pull up the seagrass roots and mooring chains move across the seabed with the changing tides and currents scouring the seabed of life, resulting in immense damage to the habitat.

Although the seagrass areas in Tor Bay are voluntary no-anchoring zones, Wild Planet Trust is actively looking to encourage water enthusiasts and boat users to respect the seagrass by not anchoring at the known seagrass locations and use these new permitted moorings.

“Anchoring in the wrong place damages the seagrass and threatens the wildlife that live amongst it,” said Dr Tracey Hamston, Conservation Officer at Wild Planet Trust.

The design of this new mooring system means damage to seagrass is prevented as the mooring chains are suspended above the seabed.
