This project assessed the condition of intertidal soft sediment estuarine habitats: 626-Distribution of mudflats and sandflats communities; 627-extent; 628-Sediment character : particle size, penetrability, OC, redox; 629-Community composition : community quality through survey of species composition (presence of typical species); 630-632-Extent and variety (range of types) of the mudflats and sandflats communities (for each of the 3 sub-features).

Closing statement
A total of 9 littoral mudflat and sandflat sediment biotopes were identified throughout the Severn Estuary SAC and SPA during the course of the study, and their subsequent extent and distribution was mapped using GIS. The macrofaunal communities within two of the biotopes were found to vary geographically, depending on their distance from the head of the estuary.
