Changes in salt-marsh vegetation

[First paragraph...]
The salt marshes on Scolt Head Island in Norfolk, Great Britain, were re-visited in August 1957 and remapped. These maps could be compared with maps prepared in 1932 and 1933. One portion, the western, of the island is in a state of steady growth and considerable changes have taken place in the marshes during the 25 years. Missel marsh, formerly a Scalicornietum striatae, with considerable bare areas, has been transformed into an Asteretum tripolii and plants of the next stage, the General Salt Marsh, are already invading the area. Very little bare ground now remains.
