Relations with other habitat types

Carex rostrata is actually a particularly frequent and conspicuous component, explaining the choice of this level IV EUNIS code. However, species like Menyanthes trifoliata, Comarum palustre, Carex diandra, C. limosa and Eriophorum vaginatum, whose dominance characterises several other EUNIS Q25 block, can become particularly abundant in some stands, to the point of suggesting the convenience of creating a new level IV regional umbrella unit.
