The shore at Happisburgh is comprised of mobile sands and shingle, due to high rates of coastal erosion, artificial sea defences have been erected to protect the cliffs. The defences change the dynamics of the shore and provide a hard substrate for organisms to colonise.
The hard substrate of the wooden sea defences is characterised by lichen, barnacle, gastropod and seaweeds that comprise littoral fringe and sand scour tolerant communities.
The wooden sea defences provide a stable hard substrate in an otherwise mobile sand and shingle shore. Habitat classification: LR (Littoral rock) and LS.LSa.Sh (Shingle and gravel shores) EUNIS: A2.11.
Small periwinkles (M. neritoides) aggregate in wood crevices.
