In this community, high, spiky tussocks of Juncus maritimus dominate and other species tend not to contribute much cover. Plantago maritima, Glaux maritima and Agrostis stolonifera are constant species, however. Armeria maritima is frequently found growing between the tussocks, as are Juncus gerardii and Aster tripolium. Occasional plants are Cochlearia officinalis, Festuca rubra, Triglochin maritimum and Leontodon autumnalis.



This is an upper marsh community that is infrequently inundated. Conditions are base-rich.



No sub-communities have been described for this community.


Similar communities

In community SM5A, Festuca rubra co-dominates with Juncus maritimus. From all other communities, this community vegetation is pretty distinct.


Conservation value

Almost all examples of this vegetation qualify as EU HD Annex I habitat 1410 Mediterranean salt meadows. It is typically a species-poor community, but many of the species that it supports are specialists.



The main threat to this saltmarsh community is probably grazing by livestock. Sea-level rises as a result of climate change could potentially have an impact, particularly in areas susceptible to coastal squeeze.
