Classification des habitats EUNIS 2022

Descriptif de l'habitat

Usually dominated by the tightly tussocky Nardus stricta, this grassland is characteristic of nutrient-poor, acidic soils, sometimes seasonally wet, on siliceous substrates through the entire lowlands and submontane belts of temperate Europe, though optimally developed in the cooler and rainier climate of the Atlantic region. Other grasses may share dominance, but the associated flora is generally rather species-poor and related to the type and intensity of grazing.
