Tilio-Acerion forests of slopes, screes and ravines

Liste hiérarchisée et descriptifs des Habitats d'Intérêt Communautaire (HIC) de la directive "Habitats-Faune-Flore"

Définition EUR 28

Mixed forests of secondary species (Acer pseudoplatanus, Fraxinus excelsior, Ulmus glabra, Tilia cordata) of coarse scree, abrupt rocky slopes or coarse colluvions of slopes, particularly on calcareous, but also on siliceous, substrates (Tilio-Acerion Klika 55). A distinction can be made between one grouping which is typical of cool and humid environments (hygroscopic and shade tolerant forests), generally dominated by the sycamore maple (Acer pseudoplatanus) - sub-alliance Lunario-Acerenion, and another which is typical of dry, warm screes (xerothermophile forests), generally dominated by limes (Tilia cordata, T. platyphyllos) - sub-alliance Tilio-Acerenion.
The habitat types belonging to the Carpinion should not be included here.

Remarques

Slight changes in the conditions of the substrate (especially ‘consolidated' substrate) or humidity produce a transition towards beech forests (Cephalanthero-Fagenion, Luzulo-Fagenion) or towards thermophile oak forests.
