Site Description: The location is situated in a large bay and is a mixture of sandstone platforms and boulders on mud and muddy sand. The bay is highly convoluted and has small muddy areas towards the landward sides. The boulder habitat consists of medium and small boulders which either congregate or are widely dispersed forming large areas of open mud or muddy sand. Much of this is covered with water forming huge 'pools' which appear rich for algae attached to boulders. The habitat is dominated by Ascophyllum on boulders and ridges but has other fucoid zones. The wet areas in the boulders have an abundance of Codium, filamentous reds, greens and browns, foliose reds and green algae. All became more abundant towards the lower shore. No laminarian zone occurred at the lower shore boulders. The platforms where the site was located consisted of sandstone platforms with boulders on top. The sides were steep and boulders and stones and muddy sand occurred towards the lower shore. Silt covered the platforms with a thin layer. Seals were seen to haul out.
