Q531 Beds of large Carex species
Description
Communities dominated by a few tussock-forming species. The main community in our ecoregion occurs in places periodically submersed by fast-flowing, mostly oligotrophic waters, with soils poor in fine sediments and rich in boulders, occurring mostly as fringes of riverine alder forests.

- Galio broteriani-Caricetum reuterianae
Relations with other habitat types
The most widespread variant is referable to EUNIS Level VI unit Q53126 [“Brotero sedge beds"]. Q51x is interpretable as an analogue in more eutrophic places with finer sediments, associated to T111 instead of T121.
