Description

Description A biological site selected to represent a type of broadleaved woodland which is uncommon in North Wales. The woodland is situated in a steep sided stream valley at low altitude and with a low rainfall. The soils are predominantly of an acid nature with a tree canopy dominated by sessile oak Quercus petraea and sycamore Acer pseudoplatanus. Other tree species present include ash Fraxinus excelsior and wych elm Ulmus glabra. The woodland has a good structural diversity with a shrub layer consisting of holly Ilex aquifolium, rowan Sorbus aucuparia and hazel Corylus avellana. A number of dead elms are the result of dutch elm disease. Many trees have climbers such as ivy Hedera helix and honeysuckle Lonicera periclymenum. The ground flora is dominated by wood rush Luzula sylvatica and bramble Rubus fruticosus. Several species occur which reflect more basic, nutrient-rich soils including ramsons Allium ursinum, harts tongue fern Asplenium scolopendrium and wood avens Geum urbanum. Bluebells Hyacinthoides non-scripta are abundant, together with other woodland species such as giant fescue Schedonorus giganteus and dogs mercury Mercurialis perennis.
