Description: Coed y Bwl is an ancient Ash woodland situated on the northwest side of the Alun Valley and overlies the Carboniferous limestone.
The wood was dominated by Elm at the southern end, grading into Ash and Sycamore towards the north, with an understorey of Field Maple. Since the decline of the Elm due to Dutch Elm disease the southern end of the reserve has been clear felled, and replanted with Ash, Common Lime and Wild Cherry.
The reserve is best known as a Wild Daffodil (2-3) wood, with these flowers dominating the field layer on the southern part of the wood in early spring together with Wood Anemone (3-5), whilst on the northern slopes Bluebell (4-6) predominate.
The wood supports a range of woodland birds including Great Spotted Woodpecker, Nuthatch, Treecreeper, Blue Tit, Coal Tit, Marsh Tit and Great Tit, augmented in the summer months by Willow Warbler, Blackcap and Chiffchaff. Birds of prey include Buzzard, Sparrowhawk and Kestrel. Tawny Owls are also resident.
Mammals include Badger, Fox, Stoat, Hedgehog, Long-tailed Field Mouse, Bank Vole, Grey Squirrel and Mole.
