Site Description: The location is situated within a small sheltered bay approx. 1 km wide. The area at the back of which is sand with some surface boulders and sides of boulders with the occasional rock ridge at the upper shore. The east headland of the bay is large rock ridges. The 'boulder' transect is situated on the eastern side of the bay. The transect site is mostly small and medium boulders on stones pebbles and sand. The upper shore had rock ridges which were smooth, but had crevices perpendicular to the shore. These ridges had many crevices and small rock pools with the occasional large deep rock pool. Below the ridges was a small area of shingle and large pebbles which had Ulothrix/Urospora turf. Below this was an extensive area of boulders and shallow rock pools with stones and sand in the bottom. The rockpools became fewer towards LW. At LW, boulders became fewer and the substrate became stony and pebbles. The biological zones were clearly defined with the shore tending to be dominated by fucoid/Ascophyllum. The shore backing was moorland, a golf course and farmland. The ridges of the upper shore had a prolific lichen flora.
