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

Définition EUR 28

Forests of hardwood trees of the major part of the river bed, liable to flooding during regular rising of water level or, of low areas liable to flooding following the raising of the water table. These forests develop on recent alluvial deposits. The soil may be well drained between inondations or remain wet. Following the hydric regime, the woody dominated species belong to Fraxinus, Ulmus or Quercus genus. The undergrowth is well developed.

Remarques

These forests form mosaics with pioneer or stable forests of soft wood trees, in low areas of the river bed; they may develop also from alluvial forests of hard wood trees. This habitat type often occurs in conjunction with alder-ash woodlands (44.3).
