Liste hiérarchisée et descriptifs des habitats d'intérêt communautaire de la directive "Habitats"

Description

Beech forests with Ilex, growing on acid soils, of the plain to montane levels under humid Atlantic climate. The acid substrate corresponds to alterations of acid rocks or to silt with flints more or less degraded or, to old alluvial deposits. The soils are of acid brown type, leaching or with an evolution towards podsol type. The humus is of moder to dysmoder type. These beech forests present different varieties:
a) subatlantic beech-oak forests of the plains and hill levels with Ilex aquifolium
b) hyper-Atlantic beech-oak forests of the plains and hill levels with Ilex and Taxus, rich in epiphytes
c) pure beech forests or acidophilous beech-fir forests of the montane level, with Ilex aquifolium in the field layer.

Remarques

Oak may dominate in some of these forests due to the coppice-with-standards regime of the past centuries. If the intensity of the management decreases beech and also Ilex often regenerate spontaneously.
