    "name": "Intertidal Monitoring of Muddy Gravel, Sediments and Rocky Shore in Pen Llyn a'r Sarnau Special Area of Conservation (SAC) 2008",
    "description": "Pen Llyn a'r Sarnau Special Area of Conservation (SAC) is designated for five Annex 1 habitats and four subsidiary ones. The major features of intertidal interest are Estuaries and their constituent mudflats, sandflats and reefs, Large shallow inlets and bays with intertidal Zostera beds, populations of the shingle dwelling amphipod Pectenogammarus, piddocks in clay and lower shore boulder communities and Reefs, particularly biogenic reefs of Sabellaria alveolata. Specific areas of interest for are the intertidal sediments and rocky areas in the Glaslyn and Dwyryd Estuaries. There were two purposes for this data capture. The first was related to sediments. Sediment data was collected to test monitoring methodology, establish sites for long term monitoring and collect baseline and reference data. The second was related to the Data collected on the rocky shore to establish sand levels at key rocky areas - Port Meirion, Ynys Gifftan and Cei Ballast.",
