Graig Wood is a Site of Special Scientific Interest (SSSI), noted for its biological characteristics, in Monmouthshire, south east Wales. [1] It forms part of the wider Hael Woods complex.
The 14.3-hectare (35-acre) SSSI, notified in 1981, is located within the community of Trellech United, on the banks of the River Wye, 3 miles (4.8 km) south-east of the town of Monmouth. It is 0.5 miles (0.80 km) north of another SSSI, Lower Hael Wood. [2] [3]
The wood is jointly owned and managed by Gwent Wildlife Trust and the Forestry Commission. [4]
As with other woodland in the Wye Valley Area of Outstanding Natural Beauty, Graig Wood contains many local and rare tree species. The predominant species within the wood are ash ( Fraxinus excelsior ) and wych elm ( Ulmus glabra ), although other species present include black alder ( Alnus glutinosa ), common beech ( Fagus sylvatica ) and small-leaved lime ( Tilia cordata ). [1]
The stream banks and old buildings within the wood are home to rich bryophyte colonies. Hart's-tongue fern ( Asplenium scolopendrium ) and snowdrops ( Galanthus ) also grow on the site. [1] [5]
