| Definition | The biotope is characterised by the silt/scour-tolerant species Flustra foliacea. It is characteristic of the large bedrock terraces along the Northumberland coast which are generally fairly species-poor compared to similar situations on the west coasts which have more sponges, hydroids and bryozoans. Thuiaria thuja is often present, as are patches of Sabellaria spinulosa (see also Sspi). With increased turbidity, species-richness is lower, although the abundance of Flustra foliacea remains high. Similar assemblages occur on mixed substrata although these tend to be dominated by ephemeral hydroids (see Flu.SerHyd and SNemAdia). Other similar biotope include those dominated by ascidians (As), also characteristic of slight scour and turbidity, although they usually occur in different regions of the country tending to the west/Irish Sea. In increased tides, but more shelter, a similar biotope dominated by Flustra and a variety of sponges such as Haliclona oculata and Halichondria panicea occurs (Flu.Hocu). | |
