Description

Description A biological site, Fairy Glen is a deep rocky gorge on the Afon Conwy selected for its well developed fern and lichen assemblage. Lichens include Sticta dufourii which is abundant on rocks and is associated with the rare Sticta canariensis; Lobaria pulmonaria is common and is associated with L. laetevirens and L. amplissima, both of which are local species. The humid conditions in the gorge are ideal for a rich fern and moss community. Soft shield fern Polystichum setiferum, hart's tongue fern Asplenium scolopendrium and the nationally rare liverwort, Porella arboris-vitae occur. The woodland contains a diverse vascular plant community. The gorge itself has much wych elm Ulmus glabra, sessile oak Quercus petraeea ash Fraxinus excelsior, small leaved lime Tilia cordata and sycamore Acer pseudoplatanus associated with a moderately base rich flora in places including dog's mercury Mercurialis perennis, wood anemone Anemone nemorosa, bluebell Hyacinthoides non-scripta, ramsons Allium ursinum and early purple orchid Orchis mascula. Large areas of more acidic woodland are domlinated by sessile oak Q. petraea and downy birch Betula pubescens with a ground flora of heather Calluna vulgaris and bilberry Vaccinium myrtillus. Numerous streams run into the gorge beneath alder Alnus glutinosa and contain herb rich flushes including such species as hemlock water dropwort Oenanthe crocata and globeflower Trollius europaeus. Parts of the wood have had beech Fagus sylvatica and conifers planted. Breeding birds include dipper, pied flycatcher, redstart, wood warbler and buzzard. Otters have been reported. Invertebrates include the very scarce alder leaf beetle Plagiosterna aenea and pearl bordered fritillary Clossiana euphrosyne and snails including the local Zenobiella subrufescens and Balea perversa. Remarks: Within the Snowdonia National Park. Partly owned by the National Trust and the Forestry Commission.
