Caer Drewyn, Clwydian Range and Dee Valley AONB

Heather and Hillforts

Heather and Hillforts are two of the most striking features of the Clwydian Range and Llantysilio Mountain.

The distinct purple heather moorland that carpets the Clwydian uplands contributes to creating its outstanding beauty and is a valuable habitat for wildlife as well as providing grazing for sheep. The upland moorland contains a patchwork of heather, bilberry, gorse and bracken, a habitat that is of European importance. It is home to a special community of upland breeding birds such as the rare black grouse, the red grouse, hen harrier, ring ouzel, whinchat and wheatear.

The landscape holds the footprint of past communities and cultures. Dominating the skyline is the exceptional chain of 2,500 year old Iron Age Hillforts, one of the highest concentrations of such in Europe. The Heather and Hillforts of the Clwydian Range form the basis of a major heritage project in the area. The project aims to conserve and restore the natural and historic heritage of the area whilst encouraging greater understanding and enjoyment of these uplands amongst residents and visitors alike. The combination of the natural and historic heritage of the Clwydian Range and Llanttysilio Mountain create a truly unique landscape greatly valued for its beauty, wildlife and archaeology, which remains to be discovered by many.
