Site Description
Bovey Valley Woodlands including Becka Falls and Yarner Wood, Holne Wood, Walkham Valley, Wistman's Wood,
Buckland-in-the-Moor,Dendles Wood - The sites selected have been chosen for the large number of old forest lichen species listed on the Western Scotland Index of Ecological Continuity (WSIEC). These woodlands are important as they support many lichens with a blue-green photobiont such as species of Collema, Fuscopannaria, Leptogium and Parmeliella. These species are distributed within the ABZ from Portugal to western Norway, but Western Scotland provides the European headquarters for many of these species.

Whiddon Deer Park - Ancient parklands are rare within and European context, with the British Isles support the vast majority of the resource. Originating from Medieval and Tudor times there main purpose was to provide a source of food and fuel for their owners. They often encompassed areas of ‘waste’ including ancient woodland. The sites selected have been chosen for the large number of old forest lichen species listed on the New Index of Ecological Continuity (NIEC) 37/70 and the East Scotland Index of Ecological Continuity (ESIEC), and represent the geographical differences between the more oceanic types from Cornwall, Devon, Wales and Scotland and the more lowland types from Dorset eastwards.
