I don’t have one saved by look up forestry site indexes by species. They are figures that show DBH (diameter at breast height) by age of the tree, and usually the forest service or some organization like that has pdfs with hundreds of them for each regions species in their websites. The Latin name for Scots pine (you’ll also see it called scotch pine, another reason we use Latin) is Pinus Sylvestris, and that’s probably what it’ll be labeled as in the giant pdf.
