Seagrass is the only marine flowering plant found subtidally in the UK and seagrass beds are considered of National Importance. In 2012 Seasearch volunteers undertook a one day survey to verify the presence of seagrass beds at Rhoscolyn, Anglesey, North Wales. Following the successful Seasearch search for seagrass, CCW undertook a snorkel survey to establish the size of the larger bed to the west of the bay. 1. Confirm the presence of seagrass beds at Rhoscolyn. 2. Note estimates of density and depth of live seagrass in different parts of the bed 3. Make note of any unusual features of the seagrass bed.

Lineage

Data is captured by using Seasearch volunteer divers. Countryside Council for Wales staff followed up the initial Seasearch survey with a snorkel visit and using GPS to map the western bed May 2012. Prior to 2002 there were reports of seagrass washed up at Borthwen Bay near Rhoscolyn. In 2003 Seasearch attempted to locate the bed, occasional shoots were recorded. An annual Seasearch skills refresher day was carried out on April 14th, 2012, to confirm the presence and location of a Borthwen seagrass bed and associated species.
Additional Information

A mini-report was written to summarise the findings: "Greenhalgh and Morris (2012). Seagrass beds of Borthwen Bay Rhoscolyn Anglesey 2012. Seasearch Report". Available online at Seasearch website.
