Cultivation of hybrid poplars (Populus trichocarpa x. P. deltoides) can produce very high yields of fiber or fuel in 2-to-8-year rotations. Cuttings were 4 to 5 feet long and from 0.5 to 1.5 inch diameter at their base. The wood and buds were burned down to charcoal and used as ceremonial incense. Without disturbance, cottonwood is replaced by other species on upland sites. Introduction to growing Black pepper from seed and cuttings. Cuttings root most readily if they are cut and planted in late fall through early spring, when dormant. HINCKLEY, and R.F. Brush material is used for certain slope bioengineering techniques and is usually 6-12 feet long with diameter not specified. Cottonwood and Willow Pole Planting Suggested Methodologies for Cottonwood Pole, Willow Whip, and Longstem Plantings This guide describes techniques for harvesting, storing, and planting various types of plant materials, including dormant cottonwood pole cuttings, willow whip cuttings, and longstem products. Availability varies over time. Let the pressed oil rest for an hour or so. Cottonwood is a well-known, common tree along rivers and streams throughout the West. Decay fungi are common; two species are noted for significant damage in British Columbia, Spongipellis delectans and Pholiota destruens. Considering its productivity, vegetative reproduction, and low risk of being affected by damaging agents, it is a suitable species for intensive management on flooded sites. It also colonizes disturbed upland sites with adequate moisture. Cruising and Harvesting Diameter at breast height and total height can be used with tables or equations to estimate total tree volumes in cubic feet and sawlog volume. Cottonwood favors moist, well-drained soil along waterways. KELLOGG, R.M., and E.P. Characteristics Black cottonwood is a soft, light wood of uniform texture. Certain species native to the Pacific Northwest will grow new plants from cut sections of branches planted into moist soil. The British Columbia Forest Service has identified site-quality classes for natural cottonwood. black cottonwood (Populus trichocarpa) was chosen as a model tree species for genomics research due to its small genome size, fast growth, high transformation frequency, simple vegetative propagation, and ease in tissue culture (Boerjan, 2005).

Green 4/4 lumber can be dried in 8 to 12 days, and air-dried material can be dried in 4 to 8 days. Cuttings are a mainstay for bioengineering techniques-techniques that incorporate live plant materials in engineering practices for stabilizing soil: live crib walls, brush mattresses, soil lifts, retaining walls, fascines, rip rap, and gabions. Many kinds of wildlife use the foliage, twigs, and buds for food, and the tree is planted for shade and in windbreaks and shelter­ belts. Cuttings are relatively inexpensive and simple to install-under the right conditions, they are easy and economical to plant. Interactions with Wildlife Because of its large size and relatively long life, black cottonwood is a superior wildlife tree in riparian areas. Salix sitchensis, Sitka willow: Good rooter, common on streams, Salix lucida (lasiandra), Pacific willow: Good rooter, common in wetlands and riparian zones, somewhat brittle and thus more difficult to pound, Salix scouleriana, Scouler willow: Drier sites and marine shores, roots slowly, often lower success rate than other willows, Salix hookeriana (piperi), Hooker willow: Occurs mainly within 5 miles of salt water, good rooter, Salix geyeriana, Geyer willow: Good rooter, Populus balsamifera, Black cottonwood: Good rooter, becomes a tall (>100') tree, Symphoricapos albus, Snowberry: low-growing shrub, tolerates dry soil and sun, good rooter, rhizomatous, excellent for erosion control, Cornus sericea, Red-osier dogwood: Inconsistent results, sometimes high success rate but other times much lower success rate than willows, Other species may be available upon request. Long cuttings of up to 10 ft have been used successfully in some cases; problems with inadequate rooting and poor stem form are common with long cuttings, however. The table below 2 provides a dry-kiln schedule appropriate for the indicated thicknesses.
