No sub-communities are currently described.
Pobail chosúla
Zostera marina occurs infrequently in the SW1A Ruppia maritima/cirrhosa lagoon community, but there it is usually subordinate to the tasselweed.
Luach caomhnaithe
Zostera beds are used in Ireland as bioindicators of ecological quality status for purposes of reporting under the Water Framework Directive (see Wilkes et al. 2017). Species/1 m2 = 1.2, n = 6.
Bainistíocht
Intertidal Zostera beds can be impacted by vehicular traffic, for example that in involved in aquaculture. Eutrophication of coastal waters can lead to smothering of beds by opportunistic algal growth.
