From 2010-2012 all known saltmarshes larger than 3ha were surveyed across the Scottish mainland and offshore islands, to compile the first detailed comprehensive national survey of this habitat in Scotland. All saltmarsh and brackish swamp was mapped using the National Vegetation Classification. All mapped areas were digitised to a 1:4,000 scale GIS database. The condition of each saltmarsh site visited was assessed. The primary aims of the Scottish Saltmarsh Survey (SSS) were to obtain information on the morphology, vegetation community structure and species found on saltmarsh sites above 3ha in area or 500m in linear extent.
The survey was a joint project between Scottish Natural Heritage (SNH) and the Scottish Environment Protection Agency (SEPA).The saltmarsh survey was tendered in 2009 and awarded to NatureBureau Ltd, who began work on the project in 2010.
