Also like willows, leaf buds contain salicin which is a powerful anti-inflamatory and pain-reducer. Black Cottonwood contains a large amount of rooting hormone, just like willows, so it is useful for plant propagation. Black cottonwood has low drought tolerance; it is flood-tolerant but a playful cub climbs around the cottonwood tree. It is fast growing and moderately long-lived. Picea glau­ca. It is a parent of fast-growing hybrid poplars such as P. trichocarpa x p. deltoides, which are being grown specifically for paper products and biofuels. Black Cottonwood can grow up to 45 ft. in the first 7 years and up to 200 ft. tall maximum at mature height. The bark comes from trees that have been dead for five to six years.

By Forest Jay Gauna Populus balsamifera ssp. Balsam poplar is a large tree with a narrow, open crown of upright branches and fragrant, resinous buds with a strong balsam odor. Paper Birch. P. trichocarpa has an extensive and aggressive root system, which can invade and damage drainage systems. The reason this is important is that trees tend to have a certain failure pattern that is common to them - in the cast of our native Black Cottonwood, it is that limbs break out in storms. Bruised leaves were also placed on cuts as an antiseptic. Seeds ripen late May to July.

Black Cottonwood is also a favorite nesting or perching tree for many bird species (Bald Eagle, owls, ospreys, hawks, hummingbirds, woodpeckers, etc.). Image courtesy Oregon State University Extension [14] These results may be important in resolving debate in evolutionary biology regarding somatic mutation (that evolution can occur within individuals, not solely among populations), with a variety of implications.[15]. Living trees are used as windbreaks. The variation within a specimen is as much as found between unrelated trees. Pistillate catkins at maturity are 8 to 20 cm long with rotund-ovate, tricarpellate subsessile fruits 5 to 8 mm long. The bark is grey and covered with lenticels, becoming thick and deeply fissured on old trees.

The roots are however invasive, and it can damage the foundations of buildings on shrinkable clay soils if planted nearby (Mitchel 1996). Trees Live Here. It is used for timber, and is notable as a model organism in plant biology. After logging operations, it sometimes regenerates naturally from rooting of partially buried fragments of branches or from stumps. • Grows well on moist fertile to dry sterile coarse soils that are flooded, i.e. It reaches from the Pacific Ocean to the Rocky Mountains. In large trees, the lower branches droop downwards. Names: Black Cottonwood is also known as Balsam Poplar. Use by wildlife: Streamside Black Cottonwoods create favorable fish habitat by providing stream bank stability, increasing nutrient availability by the shedding of leaves and twigs, and creating a shaded microclimate.
