Kearney, Outer Ards.
Survey number: 555 Event number: 19850628/21 Date: 1985-06-28 GPS: 54.38700,-5.45800. Depth: 3.5 to 0.2 m. [ View map ]
Site Description: The location consists of moderately exposed highly fissured rock ridges which have a highly convoluted shoreline. Some small gravel/sand inlets are occasional amongst the ridges. The transect site is formed of three masses of ridged rock, one on the uppermost shore, one on the mid and one on the lower. The exposure to wave action is variable up the transect depending on the shelter afforded by the ridges. The biota of the site has a good algal diversity especially on the lower shore although only a fair faunal one. The site is dominated by a large patellobarnacle zone on the face of the middle ridge block with a lower shore having Fucus serratus and Laminaria digitata. The uppermost which is more sheltered by the ridges has extensive zones of Fucus spiralis and Pelvetia. Between the upper ridged block and the middle one a stone filled gulley is present. This is more sheltered and contains an area of Ascophyllum and Fucus vesiculosus. This area also contains a large deep rock pool with a good algal diversity. The patellobarnacle mid shore almost merits 'exposed' as overhangs and pools have been eroded from the rock. The supralittoral has a large diverse belt of lichens.
