CCW commissioned survey contributes to an NVC Saltmarsh survey collation (see 'part of' field). Survey was carried out in three discrete periods: July 1990, July - August 1993 and August 1994 - areas of the site were re-visited, so it is not possible to ascribe a specific date to individual community polygons, most quadrat recording cards indicated a specific date, and this has been retained in the data.
