The Doon of May is a conifer plantation associated with an Iron Age hill fort in Dumfries and Galloway, south-west Scotland. Located around 14 kilometres (8.7 mi) west of Wigtown on the Machars peninsula, it is in the parish of Mochrum in the traditional county of Wigtownshire. The plantation was purchased from the Forestry Commission by the Tinne Beag Workers’ Co-operative in 1999 and since then the co-operative has been managing the woodland for sustainable use of both timber and non-timber forest products, while increasing biodiversity and restoring native vegetation types where possible.
