Determining the ecological value of seagrass (Zostera marina) meadows at Porth Dinllaen for tourism development and stakeholder management

SEACAMS contact: Richard Unsworth 

 The small harbour of Porth Dinllaen is owned by the National Trust and it has responsibility for the management of boat moorings in the inner harbour. These boat moorings here have been found to be causing the degradation and fragmentation of the shallow water seagrass meadow, negatively affecting the integrity of the Pen Llŷn a’r Sarnau Special Area of Conservation. Other impacts such as persistent use of anchors in the seagrass, and low tide use of vehicles on the seagrass are also of concern.

This applied research project is providing Waterline, Llŷn Adventures and the National Trust with site specific information about the ecosystem service role of the seagrass meadow at Porth Dinllaen. Information on the local rocky shore will also be collected. This information will provide information for the potential development of programmes aimed at attracting tourists to utilise the seagrass meadow for snorkelling and to visit the rocky shore to see the interesting fauna.  The information will also contribute to the stakeholder engagement (fishermen, boat owners etc) process that aims to change mooring and anchoring practice at Porth Dinllaen, improving its environmental management.
