Saltmarsh Features of the Severn Estuary 1998

Use of the National Vegetation Classification (NVC) as a basis for community definition in the saltmarsh habitats of the Severn Estuary. The purpose of this data capture was to provide a detailed NVC description of Severn Estuary saltmarsh and an account of distribution and NVC associations of several nationally scarce and one locally scarce species. The survey also provided a preliminary conservation assessment for the Severn Estuary potential Special Area of Conservation (pSAC) and line transects as baseline data for future remote sensing studies.
