Habitat and floraEdit

The woods of the region are one of the most important areas of woodland conservation in the United Kingdom, being semi-natural woodland, and run continuously along the Lower Wye Gorge (which is also notified as an SSSI).[1]

There is a rich mixture of tree types and rare and local species are present. Bigsweir Woods are sited on Devonian Old Red Sandstone and quartz conglomerate. This produces acid soil. The wood is dominated by Sessile Oak but includes some Beech, Small-leaved Lime and Birch. Hazel, Beech, Small-leaved Lime also make up an understorey with Rowan and Holly. Ground flora includes Bramble, Bracken, Ivy, Dog's Mercury and Bilberry.[1]

Local herbs include Forester's Woodrush (Luzula forsteri), Bitter Vetch, Alder Buckthorn and Wood Fescue (Festuca altissima). There are carpets of Bluebell. The site supports a significant range of ferns.[1]
