Site Description: The intertidal region at this site takes the form of an igneous rock outcrop which sands 'fingers' of steep sided igneous rock out into the sea. There is a wide, flat relatively sheltered upper part of the outcrop which supports a dense growth of Fucus spiralis; otherwise the outcrop is exposed to heavy wave action. The intertidal is mainly dominated by limpets and barnacles. The gullies between the rock 'fingers' exhibit different degrees of exposure. In some, the lower shore is dominated by Laminaria, red algae and encrusting coralline algae; in others only by Alaria and encrusting coralline algae. There are boulders and cobbles on the floors of the gullies. The transect itself was taken down the steep side of one of the rock fingers. The upper part of the outcrop was flat, and contained a few rock pools. Boulders were present at the base of the transect.
