Coed Nant-y-Merddyn-uchaf is of special
interest for its area of mixed deciduous woodland developed on the
steep western valley side of the Afon Aled. The woodland
communities found here are dominated by a mixture of broadleaved
trees and shrubs including sessile oak, birch, ash, wych elm and
hazel.
