There are approximately 35 species of spruce in the world. Picea mariana, or black spruce, is one of seven that are native to North America (north of Mexico). In comparison, China has sixteen native species.
Black spruce is distributed throughout Canada, Alaska and some northeastern US states, where it is typically a plant of wet organic soils (e.g., swamps and bogs) (distribution map).
I also note that the Plants for a Future database page on Picea mariana cites a reference stating that “The sawdust, the resin from the trunk and even the needles can cause dermatitis in some people.” I don’t think I ever received dermatitis from trees while walking through bogs in Manitoba, but I do recall a slight burning feeling on my forearms from the many light scratches I received from the sharp dead lower branches.
