This association of mesic meadows includes stands at higher altitudes, usually on more acidic and nutrient-poor soils than in the habitats of Pastinaco sativae-Arrhenatheretum elatioris. At higher altitudes, Arrhenatherum elatius becomes less abundant than in the warm lowlands and low-altitude colline landscapes, which results in the increase of relative proportion of the biomass of medium-tall grasses such as Agrostis capillaris, Festuca rubra agg. and Trisetum flavescens.
