Ravine forest

Description (English)

Forests on steep slopes, frequently in ravines, where deep, well drained and fertile soils develop which allow trees such as Fraxinus excelsior, Acer pseudoplatanus, A. platanoides, Ulmus glabra and, Tilia platyphyllos and Tilia cordata to outcompete trees such as Fagus sylvatica and Quercus spp. The herb layer is dominated by luxuriant nitrophilous herbs such as Urtica diocia, Aegopodium podagraria and Impatiens noli-tangere, moisture-loving vernal plants like Allium ursinum and, on the typically base-rich soils, Mercurialis perennis, Geranium robertiamum, Brachypodium sylvaticum and Circaea lutetiana. In the southern part of its distribution thermophilous species such as Cotoneaster integerrimus, Sesleria caerulea, Athericum ramosum and Vincetoxicum hirundinaria appear.
