Porthdinllaen Seagrass Project

Porthdinllaen is a part of a marine conservation area called Pen Llŷn a’r Sarnau (PLAS) Special Area of Conservation (SAC) .  This area extends from Nefyn on the north coast of the Llŷn to Clarach, about a mile north of Aberystwyth.  This area has been chosen as a SAC because of the marine habitats and wildlife that it supports, including reefs, estuaries, grey seals and bottlenose dolphins.  Seagrass is an important component of the SAC and is one of the reasons this area is so special.  The seagrass bed in Porthdinllaen is one of the largest and the densest in North Wales with recent surveys estimating it to cover an area the size of 46 football pitches.

The seagrass in Porthdinllaen is part of the intertidal mudflats and sandflats feature of the PLAS SAC.  This feature is in unfavourable condition.  One reason is the effect of anchoring and mooring on the seagrass in Porthdinllaen.


The aim of this project is to develop and implement management options that will improve the condition of the seagrass whilst allowing the existing use of the bay to continue.  The aim is to develop and implement these management options in full partnership with stakeholders.
