Effects of Storage, Planting Date, and Shelter on Engelmann Spruce Containerized Seedlings in the Central Rockies
Western Journal of Applied Forestry
Containerized Engelmann spruce (Picea engelmannii) seedlings were treated with different nursery storage methods, planting dates, and amounts of overstory shelter after planting. Third-year survival of seedlings stored in refrigeration did not differ from that of seedlings maintained in a lathhouse prior to planting. Survival of seedlings planted in mid-June was about 70% compared to 48% for seedlings planted in late July. Survival was only 52% within strip shelterwood units and more than 72% in the more protected environment of uniform shelterwood units. Seedlings within strip shelterwood units were slightly taller after 3 years than those under a uniform shelterwood.
