Knowledge capture and transfer in rock art studies: Results of a questionnaire on rock art decay in Britain

Abstract

Several thousand prehistoric rock art sites are known in Britain, yet the degree of preservation of these engravings remains a poorly researched and undervalued aspect of the historic environment. Our lack of knowledge has severe implications for how we interpret the rock art sites and how we conserve and manage them. The ongoing ‘Fading Rock Art Landscapes’ project aims to address this gap in our knowledge by gathering information on the rate and nature of decay in prehistoric engravings. As part of the project, a questionnaire was distributed to a number of individuals who, for up to thirty years, have been visiting and recording rock art and who have a detailed knowledge of the sites, how they have changed over time and the types of threat to which they are exposed. In particular, the questionnaire aimed to capture individuals' perceptions of how three groups of agents (physical/chemical, animal, human) influenced the degradation of the engravings. The synthesized results reveal common perceptions of a duality in the rate and nature of decay, with a slow background level of erosion caused by physical and chemical agents, over which is superimposed a rapid, variable degradation from the impact of humans and animals.
