Scotch pine (Pinus sylvestris, also frequently called Scots pine) is an introduced species in the North Country; it is native to Europe and northern Asia. It is easily identified by its bark, which is smooth or scaly and bright yellow or orange on the branches and upper trunk; and by its needles, which are shorter than those of red or white pine, grow in clusters of 2, and are twisted (unfortunately, I do not have a good picture of the needles at this time). I've also included pictures of the species' cones and buds.
