A pilot has already begun in Falmouth the place buoys have been positioned in three key areas to guard over 20 hectares of seagrass meadows, equal to twenty soccer pitches.

An area boat consumer engagement marketing campaign has additionally begun and bottom line bio-diversity measurement has been performed with assist from e-DNA evaluation specialists.

The second mission website is already lined up in Torbay the place an extra 50 hectares are deliberate for defense. That is being supported by a variety of business and supply companions.
