Glen Devon main block was purchased in 1937, Glen Sherup in 1965 and Little Rigg (in three parts) around 1970.

The forests are situated in the heart of the Ochil Hills to the south of Auchterarder. Despite being relatively large blocks, stretching from valley floor to hill-top, they are mostly hidden from view in the folds of the hills - except when close to them, or from an elevated position.
