Download full pdf synopsis: SM3A
This is a community of typically fairly short vegetation dominated by Plantago maritima with the pink heads of Armeria maritima scattered throughout. The other constant species are Aster tripolium and Glaux maritima. Frequently growing with these plants are Triglochin maritimum, Festuca rubra and Juncus gerardii. Occasionally, some Puccinellia maritima, Cochlearia officinalis or Limonium humile can be spotted.
This is a middle marsh community that is occasionally inundated. Conditions are base-rich.
No sub-communities have been described for this community.
This community is sister to SM3B and quite similar. Here, however, Puccinellia maritima is only occasional and does not dominate. From most other saltmarsh communities, the abundance of Plantago maritima differentiates.
Almost all examples of this vegetation qualify as EU HD Annex I habitat 1330 Atlantic salt meadows. It is typically a species-poor community, but the species that are present 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.
