    "description": "The results of monitoring the extent and species richness of a distinct area of mixed sediment that lies east of Llanbedrog beach. The muddy gravel community is - IMX.VsenMtru (Venerupis senegalensis and Mya truncata in lower shore or infralittoral muddy gravel), and has a high biodiversity of epifauna, flora and infauna, due to the admixture of cobbles, pebbles, gravel, sand and mud. This provides many different habitat niches. The habitat is located within the Pen Llyn a'r Sarnau Special Area of Conservation (SAC) on the lower shore at Llanbedrog. In fully marine conditions on the lower shore, this habitat can be particularly species rich due to the complex nature of the substratum supporting a high diversity of infauna and epifauna, however many factors affect the habitat, physical disturbance, bait digging, organic enrichment, introduction of non-native species etc. The purpose of this data capture was to map the current extent of muddy gravel, define the character of the muddy gravel for in situ recognition, identify current known species composition and identify location for representative core sampling and Particle Size Analysis.",
