Drought during the first growing season following outplanting and damage by rodents and snow during the 2nd year were the principle causes of mortality in a test of containerized Engelmann spruce (Piceaengelmannii Parry) planting stock. Stem caliper at planting is an important indicator of 1st- and 2nd-year survival. The increased survival of seedlings with large initial caliper reflect improved root regeneration and decreased susceptibility to bending and breaking by snow.
