Please note 1970s photographs added for comparison as I am very concerned about the erosion of this sector of Blackdown, see also Richard Webb Beacon Batch 2000.
Once cut this erodes down rapidly and persistently and while it was burned in either the 1976 or 1978 moorland fires, Sheila Ross (Soil Science) University of Bristol (1982) has seen the results. Len Curtis had the same problems for Exmoor 1982 1983 as National Parks Officer. This photograph by John Thorn appears to indicate motorbike or four wheel vehicle passage and wash.
