Variable salinity clay and firm mud characterized by a turf of the polychaete Polydora ciliata. Polydora ciliata also occurs in high densities elsewhere - see MCR.Pol. (May be a specific feature of the Humber Estuary in these conditions). This biotope occurs only in very firm mud and clay and possibly submerged relict saltmarsh with a high detrital content. It is characterized, and can be separated from other biotopes, by a combination of the sediment characteristics and the very high density of Polydora ciliata. (Information taken from the Marine Biotope Classification for Britain and Ireland, Version 97.06: Connor et al., 1997a, b).
