I see you have consulted with Reforesting Scotland. Could I ask you to speak with them about their 1000 Huts campaign A small number of such wooden huts in among newly planted woodland could provide an extra annual income whilst offering people a chance to get close to nature. The requirements are a source of drinking water and some form of basic access track nearby. RS's requirements are landlords who are open to new thinking about their land!
Oh - and you are very Welcome! It is fantastic to see a local estate being bought by someone with a genuine understanding of ecological issues, rather than just another rich guy who wants to shoot things.
