Large populations of Pomatoceros triqueter and Enteromorpha linza are observed on stones further seawards, and the substrate supports Lanice conchilega, Arenicola marina, Nephytes hombergi and Ptercladia capillacea. A black layer occurs at ~15cm depth and the substrates' high organic content is due to much leaf-litter. The fauna become less diverse and rich downshore.

Pelvetia canaliculata, Enteromorpha linza, and small populations of Chondrus crispus, Cladophora rupestris, Lithothamnion/Lithophyllum, Corallina officinalis and the lichen Verrucaria maura are also present. Fauna observed include Semibalanus balanoides, Janua pagenstecheri, Pomatoceros triqueter, and high densities of the gastropods Gibbula umbilicalis, Littorina saxatilis, L.littoralis and Patella vulgata.

On the western margin of Skern is a grassy sward, cut by channels. This environment supports diatoms, but very limited macrofauna.
