Site Description: The transect was taken across the largest Ascophyllum dominated sandstone ridge platform on the outer part of Granagh Bay, beside the Narrows. There was a tidal race between the transect site and on offshore island. The supralittoral above the transect contained rock ridges with a good lichen diversity below flat grass topped area, with some saltmarsh algae growing between the grass.
