Download full pdf synopsis: FW3J
Potamogeton natans is the only constant of this quite variable aquatic community and is usually a modest dominant. Occasionally found floating beside the pondweed are patches of Lemna minor or pads of Nymphaea alba. In an emergent element, Equisetum fluviatile and Phragmites australis are both frequent while Menyanthes trifoliata, Hippuris vulgaris, Mentha aquatica, Eleocharis palustris and Apium nodiflorum occur less often.
This community occurs in mesotrophic, fairly base-rich waters in lakes, lagoons and turloughs.
No sub-communities are currently described.
This community is closely related to the FW3A Nymphaea alba – Phragmites australis aquatic community, but can be differentiated on the contrasting frequencies and abundancies of Potamogeton natans and Nymphaea alba.
This is species-poor aquatic community. Samples have been recorded from lagoons which correspondent with the priority EU HD Annex I habitat 1150 Lagoons*. Samples from turlough basins correspond to priority habitat 3180 Turloughs*.
This is an unmanaged community. The main threat would appear to be eutrophication.
