An Ancient Woodland Site of 506 hectares (1214 acres) approximately half of this area is conifer, mainly Norway Spruce and Douglas Fir.
The remainder of the wood comprises broad-leaved trees, largely Oak and Beech.
The woods are noted for their show of spring flowers, in particular the Wild Daffodils.
The whole area is home to a variety of plants and animals, both common and rare. Particularly rich in fauna and flora are the Nature reserves within the woods, namely the SSSI and ASNW (Ancient Semi-natural Woodland).
