Foreword The Improvement Programme for England’s Natura 2000 sites (IPENS), supported by European Union LIFE+ funding, is a new strategic approach to managing England’s Natura 2000 sites. It is enabling Natural England, the Environment Agency, and other key partners to plan what, how, where and when they will target their efforts on Natura 2000 sites and areas surrounding them. As part of the IPENS programme, we are identifying gaps in our knowledge and, where possible, addressing these through a range of evidence projects. The project findings are being used to help develop our Theme Plans and Site Improvement Plans. This report is one of the evidence project studies we commissioned. There is a long history of the use of fire as a management tool within the UK uplands and it is supposed that early hunters and farmers used burning to promote fresh growth for the management of prey animals and domesticated livestock. In the last 200 years, fire in the form of rotational burning has mainly been associated with livestock grazing and the management of grouse for shooting. Increasingly, in the English uplands, the emphasis upon burning has been for the management of heather by the grouse shooting industry and in England, this is pronounced in the Pennines, North York Moors and Bowland Fells. Rotational burning is subject to the guidance set out in the Heather and Grass Burning Code which has been through several revisions over time. Many upland areas in England are designated under domestic and international nature conservation legislation designed to protect their nature conservation interest. As a result, rotational burning is an activity that will often require consent from the statutory nature conservation agency for England (Natural England) and payments are also made through agri-environment schemes so that burning is carried out in ways that are intended to ensure environmental benefits. Until recently, we did not have the technical capability for monitoring rotational burning but a method has now been developed that makes this possible. This project has allowed the development of GIS products that can be used to implement a programme of monitoring of rotational burning. This report has two objectives. The first is to provide a summary of the history of rotational burning in the English uplands going back 60 – 70 years. This is to help provide historical context from data on the intensity and scale of rotational burning since World War 2 which can then be compared with rotational burning as is currently practiced. The second objective is to interpret the GIS products from the work and place them in a form that can be readily understood by the non-specialist reader.
