Swineley Point, Belfast Lough.
Survey number: 555 Event number: 19860528/21 Date: 1986-05-28 GPS: 54.66700,-5.70600. Depth: 3.5 to 0.2 m. [ View map ]
Site Description: The site is situated on an exposed shore of fissured rock ridges which are nearly totally dominated by patellobarnacle community. The hard mud stone has many fissures which form crevices and couloirs throughout the shore. The orientation of the ridges forms sheltered areas in which pools and couloirs occur. In the upper shore, Pelvetia and Fucus spiralis tend to form zones in those areas. Pools, couloirs and gullies which are stone filled occur between the ridges throughout the shore. Encrusting corallines tend to be common in all rock pools at all shore heights. The shore had a Mastocarpus zone at the bottoms of the ridges with a sublittoral fringe of laminarians. The shore had a small saltmarsh intrusion and was backed by grass slopes and trees. A stream flows onto the shore to the east of the transect onto a small boulder bay which is more sheltered. Ulva (originally recorded as Enteromorpha) and Pelvetia/Fucus spiralis dominate the gulley formed, but it was too far away to have any effect on the transect.
