Medio-European ravine forests

Description (English)

Atlantic and medio-European collinar and submontane forests of Fraxinus excelsior, Acer pseudoplatanus, Acer platanoides, Ulmus glabra, Tilia platyphyllos, Fagus sylvatica, Quercus robur, on unstable scree or colluvions of abrupt, shady and humid slopes, with abundant ferns, characterized by the presence of the ecological group of Asplenium scolopendrium, Mercurialis perennis. They are characteristic of the hills, mountains and plateaux associated with the Hercynian ranges, the Jura, the Northern Carpathians, the Alps, the hills of the Pannonic plain, within the range of the Fagion medio-europaeum. Sub-Atlantic forests of calcareous hills of the Paris Basin, of Burgundy, of the Plateau de Langres, somewhat intermediate between these formations and those of unit T1F5 are included, in view of their restriction to situations of cool microclimates without marked summer drought, in particular, north-facing slopes and the lack of thermophilous species characteristic of the Tilenion platiphylli.
