R1M2 Agrostis-Festuca grassland
Description
Mesophile acidophilous grasslands formed by species of Agrostis and Festuca, in association with other grasses such as Danthonia decumbens or Galium saxatile, interpretable as a lowland analogue of R43z and an acidophilous analogue of R1A3. They often occur in dynamic, grazing-mediated mosaics with shrublands of EUNIS level III block S33, as well as the less soil-eroded variants of S42.
