Fraxinus - Sorbus aucuparia - Mercurialis perennis forests

English name: Ash - rowan - dog's mercury forests

Description (English)

Forests and woodland of Fraxinus excelsior, with some Ulmus glabra, Acer pseudoplatanus, Quercus petraea, Betula pubescens, Sorbus aucuparia and an understorey dominated by Corylus avellana, often accompanied by Crataegus monogyna or occasionally Crataegus laevigata, characteristic of submontane climates and moist soils on calcareous bedrocks of the northern and western British Isles, particularly in valley heads of the upland fringes, distributed in Ireland, Scotland, northern England, Wales and locally Devon. Ferns (Athyrium filix-femina, Dryopteris spp., Blechnum spicant), grasses (Brachypodium sylvaticum, Deschampsia cespitosa, Poa trivialis, Arrhenatherum elatius, Dactylis glomerata, Holcus lanatus, Holcus mollis, Agrostis capillaris, Anthoxanthum odoratum), Oxalis acetosella are abundant and characteristic in the field layer, often with Hyacinthoides non-scripta, Mercurialis perennis, tall herbs (Crepis paludosa, Crepis mollis, Filipendula ulmaria, Conopodium majus, Trollius europaeus) and an extensive and diverse bryophyte flora.
