The village also has a disused quarry which has become colonised by many interesting plants, moths and butterflies, including the dingy skipper and white-letter hairstreak: a small colony of the silver-studded blue, introduced from Prees Heath in the 1970s, may now have died out. The quarry was originally opened in 1927 to provide materials for the construction of the Mersey Tunnel; quarrying ceased in 1971 when the were allowed to regenerate naturally. The area was designated a SSSI in 1989 and were purchased in 1990 by the North Wales Wildlife Trust as a nature reserve.
