Note that reforestation up here is a different game than in places like California (read: "warmer locations more amicable to life"). Species that survive here mostly already existed and trees grow very, very slowly. For the most part, we'll welcome anything that will survive, and turns out (big surprise) that our existing species are the best at surviving here. An exception (as in, a newly introduced potentially invasive species) is the Californian Poplar, which was imported in the 40s, but that isn't really used much for reforestation anymore. There are notable examples of invasive species in the non-tree category though, the Lupine probably being the most controversial. It's been used to reclaim and create soil in sandy areas and in only a few decades since being imported, the blue of the flowering lupine absolutely dominates some areas. I think it's pretty, but it's aggressive as all hell.
