A field trial was conducted investigating the single season growth response of 1+0 PSB Engelmann spruce (Picea engelmannii Parry ex Engelm.) and lodgepole pine (Pinus contorta Dougl. ex Loud.) seedlings planted into two different soil thermal regimes at three high-elevation locations spanning km in the Engelmann Spruce-Subalpine Fir.
Its associates are the mountain climbers of the tree kingdom, Engelmann spruce, Lyall larch, limber pine, alpine fir, foxtail pine, Rocky Mountain juniper, knobcone pine, and western juniper. Its dark green needles, stout and rigid, are from one and one-half to two and one-half inches long. ASB members receive the SOUTHEASTERN BIOLOGY as part of their membership dues.

The white pine weevil, Pissodes strobi Peck, is a pest of young spruce, plantations in British Columbia which seriously hampers forest regeneration.
Weevils kill year old spruce leaders resulting in growth reductions and poor stem form. As accumulated heat is required for completion of the weevil's life cycle, a degree-day based hazard rating system for the weevil could be. Two main groups within Cornus are red-line dogwoods, with showy bracts below the flowers and red fruit, and blue-line dogwoods, without bracts and blue or white fruit.
Some authorities have made the dwarf red-line dogwoods into a separate genus called Chamaepericlymenum Hill (other names given this genus include Mesomora, Cornella, and. clearcutting: In Nova Scotia, a clearcut is now defined as a forest harvest where less than 60% of the area is sufficiently occupied with trees taller than meters with links to [Clearcut Definition] [Clearcut FAQs] providing more details.
