Chapel Island Causeway, Strangford Lough.

[Site list for year 1986]

Survey number: 555 Event number: 19860603/21 Date: 1986-06-03 GPS: 54.38300,-5.59500. Depth: 3.5 to 0.2 m. [ View map ]

Site Description: The western causeway is composed of an Ascophyllum dominated boulder shore on its outer side, facing the lough (with areas of muddy gravel), and of a more sedimentary substrate, mainly pebbles and muddy gravel, on its inner side facing the large tidal pool. The sedimentary areas were covered in a layer of Ulva (originally recorded as Enteromorpha) and brown algae. The transect was taken across the outer Strangford Lough side of the causeway, and a general species collection made from the tidal pool. There is a narrow strip of fringing saltmarsh above the transect, and zones 1 + 2 are fairly wide at the transect site. No Laminaria revealed.
