Castle Island Point, Strangford Lough.

[Site list for year 1986]

Survey number: 555 Event number: 19860522/21 Date: 1986-05-22 GPS: 54.46300,-5.62700. Depth: 3.5 to 0.2 m. [ View map ]

Site Description: The transect site lies at the low tide boulder causeway between the northern tip of Castle Island and Darragh Island. The upper shore is a typical silt covered Ascophyllum dominated boulder and stone shore for this area, but the boulder causeway on the lower shore allows a more extensive development of the Fucus serratus zone than is usual, and a wider exposure of Laminaria. The supralittoral is composed of small pebbles and stones on a bed of clay, with Salicornia growing between the pebbles. (Gibbula magus may sometimes be found here intertidally - personal communication from Dr. Pat Boaden).
