Sprouting from roots also occurs. The rays are very fine and scarcely visible with a hand lens. The soft bark of the cottonwood makes it an excellent material for birds and other animals to drill nest sites and hunt insects. Thickened bark on lower portions of the trunk after 10-20 years affords better fire protection, and moist soil contributes to the survival of underground parts. Weight Black cottonwood weighs about 46 lb/ft3 when green and 24/ft3 at 12 percent moisture content (MC). Mechanized harvesting is quite suitable for typical plantations on agricultural lands (fiber farms). Hand Selected and shipped right to you! Bark: Light green, smooth on young trunks; on older trunks thick, gray, deeply furrowed with flat-topped ridges. Manual of Montana Vascular Plants. Some upland sites with deep, moist, and fertile soils are also productive for black cottonwood. Mixed-species Stands Black cottonwood must maintain a dominant crown position to survive and grow. It reaches from the Pacific Ocean to the Rocky Mountains. Open-grown trees develop deep crowns with large branches, often on single, massive stems. Maybe the bark could give some clues, but I don’t know much about bark and mainly have knowledge of the wood itself. The wood is also excellent for production of plywood. Research Contribution 8. Fast growing with dark gray bark. High yield hybrid poplar plantations in the Pacific Northwest. Successful plantings are established from unrooted cuttings of 1- to 2-year-old-wood that are 12 to 24 in. Fremont's cottonwood trees range from 12 to 35 meters in height, and trunk diameter ranges from 0.30 to 1.5 meters. Each capsule contains many minute seeds with long, white, cottony hairs. Sometimes, the roots can even damage the foundations of buildings by drying out the soil. Most of the remaining volume is evenly distributed between the other regions in Washington and the Northwest subregion of Oregon. Common Name: COTTONWOOD Habit: Tree.Stem: 40 m; young bark smooth, pale yellow-green to gray; older bark furrowed, brown to gray; twigs with swellings below leaf scars; winter bud generally resinous, scales > 3.Leaf: juvenile, adult, late-season leaves may differ in size, shape, hairiness; generally glabrous; blade 3--11 cm, elliptic to deltate, veins pinnate or +- palmate, tip generally elongate. I love carving cottonwood bark, and this bark is a joy to carve. Soils Black cottonwood grows best on deep alluvial soils with good aeration and abundant moisture. 1995. Lumber and veneer are often considered to be of relatively low quality and are used primarily for cores in plywood or interior furniture parts. Scarlet. It has been kiln dried, surfaced on two sides, and is ready to use! Populus section Aigeiros is a section of three species in the genus Populus, the poplars.Like some other species in the genus Populus, they are commonly known as cottonwoods.The species are native to North America, Europe, and western Asia. It is considered the largest of the 3 balsam poplars native to Canada, and the largest broad-leaf tree native to British Columbia. The bark used for carvings needs to come from dead trees. It often forms dark colored bark. R.M. Fungal diseases are a significant threat. (It should also be noted that Black Oak, despite it’s name, is not really any darker or different than plain old red oak.) In forest stands, cottonwoods develop narrow, cylindrical crowns and long clear boles. Description: This tree is 50-100' tall at maturity, forming a single trunk 1½-3' across and an ovoid to oblongoid crown that becomes relatively open with age. Much of the precipitation may fall as snow. The growth rings are inconspicuous, and are differentiated by a thin grouping of pores, which gradually increase in density at the end of the growth increment. The depth of the sequencing was about 7.5 x (meaning that each base pair was sequenced on average 7.5 times). Wind breakage is also common, and although their root systems are windfirm, erosion of river banks commonly topples trees. Height 30-45 m. The open crown is formed by ascending branches growing in whorls. Identified in winter by: its knobbly twigs, especially on older trees. The tree likes Sun to half-shade at the location and the soil should be sandy to loamy to strong loamy. Waxy green leaves that are spade-shaped. It grows on a variety Regeneration from Vegetative Sprouts Black cottonwood sprouts readily from stumps or from buried fragments of branches. 1993. cannot tolerate brackish water or stagnant pools.. Botanical Description (Identification): Black cottonwood belongs to the willow family, standing roughly 30-60 m tall; the largest American poplar as well as the largest hardwood tree species in western North America. Hibbs. Volume 2, Hardwoods. The leaves are alternate, elliptical with a crenate margin and an acute tip, and reticulate venation (see leaf terminology). A cottonwood in Willamette Mission State Park near Salem, Oregon, holds the national and world records. The Black Poplar is botanically called Populus nigra. Variation within the species: black cottonwood is most commonly and widely known as the distinct species Populus trichocarpa but is sometimes treated as Populus balsamifera var. Although it is tolerant of winter flooding, it requires adequate drainage during the growing season. Average service life of untreated cottonwood posts in ground contact is 4 to 5 years. Influence of soil water on the physiological and morphological components of plant water balance in Populus trichocarpa, Populus deltoides and their F1 hybrids. Black Cottonwood Populus Balsamfirus The poplar species are used around the world for their medicinal properties. HANLEY, and R.W. BRIT Press. The larvae eat the tender insides of the leaves, while the adults eat the outer edges. Last measured in April, 2008 this black cottonwood was found to be standing at 155 ft (47 m) tall, 29 ft (8.8 m) around, with 527 points. Black. Wood: Unimportant and seldom used. The sequence of P. trichocarpa is that of an individual female specimen "Nisqually-1", named after the Nisqually River in Washington in the United States, where the specimen was collected. Wet bottomlands of rivers and major streams frequently provide such conditions, particularly where bare soil has been exposed or new soil laid down. Download this Cottonwood Tree Bark photo now. Ecological Role Black cottonwood is a pioneer species specifically adapted to colonizing and dominating areas disturbed by floodwaters. These trees are also very important in maintaining the well-being of numerous wild animals, birds, and insects. trichocarpa (Torr. Tree Planters Notes 43(3):81-86. It grows up to elevations of 2100 m. P. trichocarpa has been one of the most successful introductions of trees to the otherwise almost treeless Faroe Islands. Cytospora canker (C. chrysosperma) is common in natural forests and may be a threat to regeneration from cuttings. Abundant seed crops are usually produced every year. Structure and pattern of variation in a 3-year field test. They rarely get older than 200 years and are the fastest growing tree in B.C. Chestnut. The leaves are 7–20 cm long with a glossy, dark green upper side and glaucous, light grey-green underside; larger leaves, up to 30 cm long, may be produced on stump sprouts and very vigorous young trees. Temperatures range from a maximum of 60 to 117°F to a minimum of -53 to 32°F. extensive stands on bottomlands of major streams and rivers at low elevations along the Pacific Coast, 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. The species was imported from Alaska to Iceland in 1944 and has since become one of the most widespread trees in the country. These scientific names are now considered synonymous with P. trichocarpa: Ewing, Susan. Deciduous male catkins are 0.8 to 1.2 in. … SWAN. Growth and Yield Height growth of black cottonwood often exceeds 5 ft per year for at least 10 years, and trees may reach diameters of 6 to 8 in. Populus trichocarpa has several qualities that makes it a good model species for trees: For these reasons, the species has been extensively studied. Regeneration also occurs from abcised shoots with green leaves, which root where they fall or are deposited by water. BLANKENHORN. Cottonwood Bark.
