This dataset contains the results from a National Vegetation Classification (NVC) survey used as a basis for community definition in the saltmarsh habitats of the Dee and Clwyd Estuaries. The purpose of this dataset was to provide systematic descriptions at the plant community level of saltmarsh and associated habitats in the Dee and Clwyd estuaries. The objective was to provide an essential basis for monitoring, facilitate management planning and improve our ability to evaluate development proposals.
