Fásra
These are dense reed beds dominated by Phragmites australis which is joined only rarely by other tall swamp species such Typha latifolia and Sparganium erectum. Equisetum fluviatile frequently occurs in an understorey, where occasionally one may find Mentha aquatica, Menyanthes trifoliata or Agrostis stolonifera.
Éiceolaíocht
This swamp community is found in fairly basic and mildly eutrophic waters fringing lakes and lagoons.

No sub-communities are currently described.
Pobail chosúla
Phragmites is found, perhaps unsurprisingly, in most of the communities in the FW3 Phragmites australis – Cladium mariscus group. It seldom, however, dominates the vegetation as strongly as it does here in this community
Luach caomhnaithe
This is a swamp community of medium species richness (species/4 m2 = 6.9, n = 75). Stands of FW3E may occur fringing lagoons corresponding to the priority EU HD Annex I habitat 1150 Lagoons*.
Bainistíocht
These reeds beds maybe exploited locally on a small scale for reed harvesting. Threats to this community include eutrophication and drainage.
