Measurement of the ages of seedlings of balsam fir, red spruce, and white spruce 15 years after the first harvest of a two-cut shelterwood operation revealed that very few potential crop-tree seedlings in the sample occurred as advance regeneration in the original stand. Relationships among total height, age, and current growth of the samples are reported, as well as the variation in seedling age encountered.
