Porthdinllaen Seagrass Project Open Day


On 4th February the Nefyn Golf Club will be the venue for an open day on the Porthdinllaen Seagrass Project. Set up during 2012 as a partnership project between the Pen Llŷn a’r Sarnau Special Area of Conservation, the National Trust and other stakeholders, the project aims to investigate ways of protecting the important seagrass bed at Porthdinllaen without impacting on the current use of the area. The open day will be an opportunity for the project team to provide information and ensure that all interested parties understand the project and are comfortable with how it’s proceeding.


The seagrass bed at Porthdinllaen is one of the largest in North Wales and forms part of the Pen Llŷn a’r Sarnau Special Area of Conservation. Seagrass beds are an incredibly important habitat, not only do they support a wealth of biodiversity but they provide important benefits such as nursery areas for commercial fish species.  They also help to absorb carbon dioxide, produce oxygen, cycle nutrients and filter pollutants. At least 80% of the UK’s seagrass has been lost in the last century due to disease, poor water quality, coastal development and pollution amongst other factors and seagrass is now classified as nationally scarce.


Evidence suggests parts of the seagrass bed at Porthdinllaen are being degraded by mooring and anchoring activity and the project aims to investigate ways to prevent this degradation and enhance the quality of this important natural resource.


On the day there will be a drop in session between 3-5pm, light refreshments between 5-6pm, a presentation on the findings of the project so far at 6pm and then two workshops at 7pm. The workshops will be looking at possible adaptations that could be made to mooring systems at Porthdinllaen to limit their impact on the seagrass, and discussing potential development of a snorkel trail in the bay and the educational and economic opportunities this may provide. There is a warm welcome to all to any part of the day.
