Site Description: The transect site runs across the intertidal at the southern tip of St. John's Point, between the lighthouse and a newly constructed wall. The top of the transect is on a raised ridge outcrop on the upper shore, behind which lies fractured ridges and stones with scattered Pelvetia. Behind this in turn is a patchy salt marsh. Below the rock ridge outcrop the transect runs over rock ridges with boulders between the ridges and pools between the ridges. The upper shore is dominated by patellobarnacle with Nucella, and the lower shore by fucoids and Laminaria. The site is notable for a high diversity of animals, especially beneath boulders on the lower shore.
