The Severn Estuary has long been regarded as a site of international natural heritage importance but managing the wide variety of significant wildlife interests against a background of increasing human pressures represents huge challenges for the UK statutory conservation agencies. The study aim was to provide a powerful management GIS tool to support decision making processes and allow rapid assessments of the effects of human activities on local intertidal ecological features. The project involved the construct a Geographical Information System (GIS) database populated with Phase I level intertidal biotope data for the entire Severn Estuary site (English side). The study aim was to provide a powerful management GIS tool to support decision making processes and allow rapid assessments of the effects of human activities on local intertidal ecological features. The objectives of the study are summarised below: - Conduct Phase I mapping field surveys to classify and map (at 1:5000 scale) intertidal biotopes along the English side of the Severn Estuary possible Special Area of Conservation (pSAC) including Bridgwater Bay Special Protection Area (SPA). - Present a consistent biotope dataset for intertidal areas throughout the site and to compliment similar previous mapping work of sub-tidal environments (Posford Duvivier) and saltmarshes (Dargie, 1998). - Construct a Geographical Information System (GIS) database present a report giving a descriptive account of the site, highlighting significant habitats and species, and providing an interpretation of observations. - Present a report giving a descriptive account of the site, highlighting significant habitats and species, and providing an interpretation of observations.

Biotope classification was based on the v97.06 system. It has been recognised that one of the most efficient methods of ecological data acquisition and dissemination is biotope mapping and the construction of biotope maps. Biotope mapping is a well-established survey technique enabling the rapid field collection of ecological data over very large areas, such as the Severn Estuary. Data drawn from the field surveys are presented as biotope maps which show the geographical extents and variety of habitats and their component species (biotopes) within a given area. In conjunction with expert opinion, biotope maps and accompanying survey reports can be used to assess the likely ecological effects of proposed activities and the possible consequences for nationally and internationally significant ecological features. Of particular note was the very extensive honeycomb worm, Sabellaria alveolata, reefs (classified as MLR.Salv), which is noted as scarce in the UK. In some places, this biotope dominated lower eulittoral and sub-littoral fringe rock and consolidated gravel/cobble substrata. Important locations for intertidal S. alveolata reefs included Wains Hill, Ladye Point, Anchor Head, English Stones, Steep Holm Island and Stert Flats in Bridgwater Bay. In comparison to other Sabellaria reef habitats within the UK, the associated fauna of Severn Estuary S. alveolata intertidal reef habitat is likely to be very impoverished due to the high sediment loading, high current speeds and related scouring effects.
