Athough Picea rubens
underwent a period of decline during the 19th and 20th centuries, the major part of that decline happened outside of the three generation time period used to assess past declines. Additionally, while it occupies a more limited range than the other northern spruces in North America, its extent of occurrence is still very extensive and far beyond the thresholds for a threatened category. There is no current indication of decline, and it is actually expanding again in many parts of its range. It is therefore assessed as Least Concern
