Angiosperm-dominated stands of vegetation, occurring on the extreme upper shore of sheltered coasts and periodically covered by high tides. The vegetation develops on a variety of sandy and muddy sediment types and may have admixtures of coarser material. The character of the saltmarsh communities is affected by height up the shore, resulting in a zonation pattern related to the degree or frequency of immersion in seawater. Saltmarsh vegetation is generally well studied; its classification is fully covered by the UK National Vegetation Classification, where 26 types are defined (Rodwell, 2000). Pioneer saltmarsh is represented by 8 of the 26 NVC communities recognised by Rodwell (2000) and are dominated by Spartina sp., Salicornia spp., Suaeda maritima, Aster spp. and Arthrocnemum perenne communities. (Information taken from the Marine Biotope Classification for Britain and Ireland, Version 97.06: Connor et al., 1997a, b).
The literature on saltmarsh habitats is extensive and it would be impossible to include all available information in this review. Therefore, the following review is based on more extensive reviews and texts to which the reader is directed for further information (Ranwell, 1972; Long & Mason, 1983; Adam, 1993; Packham & Willis; 1997; Rodwell, 2000).
