European Nature Information System (EUNIS) habitat classification code: A1.235/B-MLR.RPid - Ceramium sp. and piddocks on eulittoral fossilized peat (Davies & Moss, 1998).
The biotope MLR.FserPid - Fucus serratus and piddocks on lower eulittoral soft rock, occurs in similar physical conditions, but the rocky substratum favours colonization by Fucus serratus rather than ephemeral seaweeds, such as Ulva and Enteromorpha spp.
