Site Description: The location is a moderately exposed fucoid dominated shore with boulders in the upper shore and sandstone platforms in the mid and lower. It is situated adjacent to Black Rock (a small offshore rock outcrop which is more exposed than the site as it has a distinct patellobarnacle/Hydropunctaria maura (orginally recorded as Verrucaria maura zonation). The upper shore has limestone and basalt boulders. These were probably placed to form a foundation for the embankment of the A2 road, which backs the shore. This has concrete and stone walls, the former of which has drainage pipes providing a freshwater influence near the transect site. The boulders of the upper shore are on top of shingle and coarse sand. The middle shore consists of smooth sandstone platforms which have crevices and wide shallow rock pools. A few boulders lie on the top. The lower shore below the step in the bottom of the platform consists of gullies and couloirs, eroded into the sandstone, which have numerous sandstone and basalt boulders. The lowermost zone, laminarians, was only surveyed superficially due to the tide having a higher low tide than predicted.
