Dartmoor Area profile: Supporting documents Introduction National Character Areas map As part of Natural England’s responsibilities as set out in the Natural Environment 1 2 3 White Paper , Biodiversity 2020 and the European Landscape Convention , we are North revising profiles for England’s 159 National Character Areas (NCAs). These are areas East that share similar landscape characteristics, and which follow natural lines in the landscape rather than administrative boundaries, making them a good decision- Yorkshire making framework for the natural environment. & The North Humber NCA profiles are guidance documents which can help communities to inform their West decision-making about the places that they live in and care for. The information they contain will support the planning of conservation initiatives at a landscape East scale, inform the delivery of Nature Improvement Areas and encourage broader Midlands partnership working through Local Nature Partnerships. The profiles will also help West Midlands to inform choices about how land is managed and can change. East of England Each profile includes a description of the natural and cultural features that shape our landscapes, how the landscape has changed over time, the current key London drivers for ongoing change, and a broad analysis of each area’s characteristics and ecosystem services. Statements of Environmental Opportunity (SEOs) are South East suggested, which draw on this integrated information. The SEOs offer guidance South West on the critical issues, which could help to achieve sustainable growth and a more secure environmental future.

    Deserted Sites and Rabhit-Warrens on Dartmoor, Devon by CATHERINE D

    Deserted Sites and Rabhit-Warrens on Dartmoor, Devon By CATHERINE D. LINEHAN This paper summarizes the evidence for enclosures and homesteads on Dartmoor from the time if Domesday onward. Part I lists the known deserted sites, including those for which there is asyet no identified name or documentary evidence. A fuller description is given ofthe deserted sites in Okehampton Park;' of three sites in a rabbit-warren on Spitchwick Common in Widecombe-in-the-Moor; if a group of sites in Corn wood; and if Butterberry in Peter Tavy. Maps are given of these four special areas (FIGS. 52, 54, 56, 58), together with a distribution-map C!f sites on Dartmoor as a whole (FIG. 47), and sketch-plans ifa number if individual sites. I Part II contains a summary of the written evidence for rabbit-warrens on Dartmoor, anda list ifI6 sites which contain pillow-mounds. INTRODUCTION HE upland region of Dartmoor in Devon contains some II 1,000 acres (FIG. 46). Of this the Duchy of Cornwall owns about 29,000 acres of un­ T enclosed land, together with certain areas of enclosed land. The remainder, estimated at about 59,000 acres, consists of 'venville commons'­ land subject to certain rights by Scale of Miles local villages." o 5 10 20 30 40 Dartmoor has long been Scale of KJlometr~5 known and studied for its pre­ 20 40 60 historic remains and mining activities. Little interest, how­ ever, has been shown in its many deserted homesteads, or in the old rabbit-warrens with their pillow-mounds, known locally as 'burys' or 'buries'.

These plans expand the concept of former National Rivers Authority's Catchment Management Plans to encompass the wider range of responsibilities of the Agency. This plan sets out the Agency's vision for realising the potential of the local environment and will be used as a principle tool by the Agency at a local and regional level in planning and delivering environmental improvements. This document is inter-related with the Tamar Estuaries Consultative Forum's Tamar Estuaries Management Plan. The latter concentrates specifically on Plymouth Sound and the estuaries of the Rivers Plym, Tamar, Tavy and Lynher, and is concerned with social, economic and environmental improvements to the estuarine catchment. An important stage in the production of both plans is a period of public consultation. We are keen to draw on the expertise and interest of the local communities and for them to have a say in the development of Agency plans and work programmes.

The Heaths have always held a special place in our hearts and minds. Until the late 1800s the Commoners were tenant farmers on the Estate who exercised their rights to graze animals and collect wood, heather and gorse. As the demands for recreation and space for exercise increased, and the use for agriculture declined, my great grandfather, the 21st Baron Clinton, signed a deed in 1930 to bring the whole area under the 1925 Law of Property Act, giving the public rights of “Air and Exercise.” My family and I are delighted that this special landscape, the ‘spine’ of the East Devon Estate, has been recognised as a National Nature Reserve.
