Thanks both
Torbjörn, I had in mind native species, which are fashionable in Scotland. Eg what we call Scots Pine (not sure what you call it – Swedish Pine?!), birch and oak, which all grow well in the area.
Muz, the 100 x 100 m block is just for the students to use (I hope) in the pilot study. But thank you for the rough costing – very helpful info. Glad to hear that we might make money, but I am now 61 so it may be my children and nephews and nieces who will benefit!
Best, Patrick
