This data set has been developed by assimilating spatial data from Scottish Natural Heritage. The whole country has not yet been surveyed and as a result the data set only displays known wetlands. The wetland inventory database comprises a number of fields that include the main WFD95 wetland type, the original habitat survey information and whether the wetland polygon is within a statutory designated site. The wetland typology (WFD95) is used as the main identifying field for each polygon in the inventory database.
