I understand we are primarily working to topography. At a detailed scale observations are being made about the likelihood of forest presence. Inthe Church Stowe scenario I have referred to the potential for willow/alder carr choking the smaller vallies and Marix Evans invokes the local boulder clay on a large scale to suggest it's poor agricultural quality may have left it un-cultivated for long perids hence the medival Whittlewood Forest. I think in the case of recent map one could suggest at site scale that steep north facing slopes with poor chalk soils may have been left uncleared, but I think that is all we can reasonably say.
