Book excerpt: This study examines factors affecting natural restocking of small openings created by partial harvesting of high elevation (> 1500 m) Engelmann spruce (Picea engelmannii Parry ex Engelm.)-subalpine fir (Abies lasiocarpa [Hook.] Nutt.) stands in east-central British Columbia, Canada. We examined the effects of opening size (0.03, 0.13, and 1.0 ha), seedbed, and seed supply on density of post-logging regeneration for 10 years post-harvest. The effect of opening size on growth release of advance regeneration was also examined. Both seed production and seedbed limited densities of post-logging seedlings. Densities of subalpine fir and Engelmann spruce post-logging regeneration remained low at two sites where seedfall was low. Seedbed scarification significantly increased seedling densities where seed rain was high. In the absence of scarification, abundant seed production had little effect on post-logging seedling densities. Increased height and basal diameter growth of advance regeneration following logging was greater on 1.0-ha than 0.13-ha and 0.03-ha openings. This study demonstrates that post-logging natural regeneration in combination with advance regeneration can restock small openings in partially harvested stands where there is an adequate distribution of mineral soil seedbed and logging or site preparation coincide with or shortly precede a year of abundant seed production.

Book excerpt: This field guide was prepared to provide the planted with the techniques needed to establish Engelmann spruce seedlings successfully. Planting principles are discussed in detail in USDA Forest Service Research Paper RM-89, 'Planting Engelmann spruce, ' which emphasizes the relationship between the physiological and silvicultural requirements of spruces and the environmental conditions to which seedlings are exposed.
