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.
Botanical Significance Noted for lichen and habitat interest. Bovey Valley, Walkham Valley, Whiddon Deer Park, Wistman's Wood, Buckland-in-the-Moor, Dendles Wood -Rare and threatened lichen within the sites selected include: Fuscopannaria sampaiana (IR), Leptogium burgessii (IR, Aii), L. cochleatum ( VU, IR), L. saturninum (VU, IR), Parmeliella testacea (IR) and Polychidium dendriscum (VU, IR). Additional vascular plant interest as identified through BSBI consultation: Dartmoor is a nationally important area with populations of many nationally scarce and rare species. In addition to those listed below many other species have locally important populations within the boundary of the NP: Vaccinium oxycoccos, V. vitis-idea, Botrychium lunaria, Carex curta, Huperzia selago, Lycopodiella clavatum, Hymenophyllum tunbridgense, etc Anagallis minima, Asplenium obovatum, Asplenium septentrionale, Carex Montana, Chamaemelum nobile, Cuscuta epithymum, Drosera anglica, Erica ciliaris, Euphrasia anglica, Euphrasia vigursii, Hymenophyllum wilsonii, Hypericum linariifolium, Hypericum undulatum, Lotus subbiflorus, Ludwigia palustris, Lycopodiella inundata, Melittis melissophyllum, Neottia nidus-avis, Orobanche artemisiae-campestris, Platanthera bifolia, Platanthera chlorantha, Potentilla argentea, Radiola linoides, Scleranthus annuus, Sibthorpia europaea, Teesdalia nudicaulis, Viola lacteal, Wahlenbergia hederacea
General Habitat Description Dartmoor is the largest and highest upland in southern Britain. It hosts a considerable variety of habitats and is of international importance for its blanket bogs, upland heaths and upland oakwoods. Additional vascular plant interest: Heath, mire, woodland and granite outcrops. Semi-improved agricultural land
Conservation Issues At Whiddon Deer Park the subsequent management of grazing and tree pollarding has resulted in sites supporting a large number of old, well-lit trees that are particularly suitable for many epiphytic lichen species.
