§ Mr. Gordon PrenticeTo ask the Secretary of State for the Environment what estimate he has made of the length of dry stone walls that(a) have collapsed and (b) are in need of substantial repair (i) in the national parks and (ii) elsewhere in England and Wales. [20397]
§ Mr. AtkinsThe Secretary of State commissioned a comprehensive survey of countryside features in 1990—the countryside survey 1990. The survey included the length and condition of dry stone walls in Great Britain. The main results of the survey were published by the Department in 1993. There are an estimated 107,000 km of stone walls in England and Wales. This total includes walls which are derelict or collapsed. No further breakdown of the results, by condition of walls or designated areas, is currently available.
