Big Wood

Big Wood lies tucked away and is not especially prominent in this locally well-wooded disturbed landscape of old mines and quarries. Occupying ground gently sloping down to the north; it is free draining into the underlying limestone. Limestone outcrops are scattered throughout the site and there are remains of lead mining activity, numerous spoil heaps and a number of shafts, across the site. The woodland extends beyond the Trust's boundary to the north and a large disused quarry lies immediately adjacent and forms part of the eastern boundary. This semi-natural ancient woodland consists of relatively uniform mature Oak and Ash, with Wych elm and Cherry and scattered exotics, especially Sycamore which has colonised the disturbed ground. It has a rich shrub layer comprised of Hazel, Holly, Hawthorn, Beech and some Sallow and Yew, with Ash and Sycamore regeneration. It has a diverse a limestone woodland ground flora. The woodlands are of likely importance to small mammals, particularly rodents. The North Wales Wildlife Trust has included the site in a local dormouse survey, these being a European Protected Species, and has erected a number of boxes. A small area of open ground exists (Cpt 1b) which is predominately calcareous grassland/tall herb vegetation in a triangle of land between the track and adjacent properties which adds to the habitat diversity. A badger sett is also present. Key features at the site are: - Ancient semi-natural woodland NVC community W8 Upland mixed Ashwood. Of likely value for small mammals, badgers and rodents, in particular dormice, the site is included in a North Wales Wildlife dormouse project. - Informal public access- the site is moderately well used by local residents following the creation of a circular path.
