South West Archaeology Ltd. was engaged by the Historic Environment Officer for the Exmoor Mire Project to undertake a non-intrusive walkover survey of the proposed mire restoration area on Larkbarrow Farm, Exmoor (NGR: SS 8202 4290). The results of this walkover survey will help to mitigate the threats that the proposed drainage ditch blocking may pose to the historic environment. The survey also aimed to identify archaeological features which might require further mitigation work prior to the blocking of drainage ditches. In total, 104 features were recorded during this walkover survey, of which 94 were wholly unknown. These included mineral extraction works, holloways, hollows and pits, mounds, and a series of individual stones. Some of these monuments are worthy of further recording prior to any ditch blocking activity. The principal features, as plotted from LiDAR data, were shell holes derived from the use of the northern part of the site as a firing range during World War Two.
