Download full pdf synopsis: DU1A



This duneland community is dominated by Elytrigia juncea which initially occurs as colonising patches on the sand but can later form dense, glaucous expanses. Other species are at best occasional. Honckenya peploides and Salsola kali are the most frequent strandline species to be encountered. Ammophila arenaria can form patches where this community merges into marram duneland.


This is a colonising community of sandy shorelines, where accretion of sand around Elymus juncea leads to the formation of embryonic dunes, usually less than one metre high.



No sub-communities are described.

Conservation value

This community corresponds to EU HD Annex I habitat 2110 Embryonic dunes. It is very species-poor.



Embryonic dunes are unstable habitats and part of the dynamic duneland system. They may be naturally removed by storms and high tides. Anthropogenic impacts including recreation and modification of the coastline.
