Annex I habitats that are a primary reason for selection of this site

  • Alyn Valley Woods holds one of the largest continuous areas of Tilio-Acerion forest in Wales, and is one of three sites selected to represent the geographic range and variation of the habitat on the Carboniferous limestone of north Wales. The canopy is predominantly of ash Fraxinus excelsior and sycamore Acer pseudoplatanus, with an understorey and ground flora typical of Tilio-Acerion in the UK. Rare or distinctive species include herb Paris Paris quadrifolia, stinking hellebore Helleborus foetidus, green-flowered helleborine Epipactis phyllanthes, toothwort Lathraea squamaria and spurge laurel Daphne laureola. The site also holds the region’s largest population of wayfaring tree Viburnum lantana.
