It is fast growing and moderately long-lived. Cottonwood is a well-known, common tree along rivers and streams throughout the West.Cultivation of hybrid poplars (Populus trichocarpa x. P. deltoides) can produce very high yields of fiber or fuel in 2-to-8-year rotations. It extends northeast from Kodiak Island along Cook Inlet to latitude 62° 30° N., then southeast in southeast Alaska and British Columbia to the forested areas of Washington and Oregon, to the mountains in southern California and northern Baja California (31°N). The sequencing was performed at the Joint Genome Institute using the shotgun method. The wood is also excellent for production of plywood.

P. trichocarpa is normally dioecious; male and female catkins are borne on separate trees. This tree, which grows rapidly, is typically found on the floodplains of rivers and streams, but is capable of growing on higher ground. In eastern Washington and other dry areas, it is restricted to protected Native. The depth of the sequencing was about 7.5 x (meaning that each base pair was sequenced on average 7.5 times). Bark: Smooth and gray on young trees. It grows on a variety They frequently climb trees to forage on fleshy fruits such as cherries (Prunus spp. Populus trichocarpa, the black cottonwood, western balsam-poplar or California poplar, is a deciduous broadleaf tree species native to western North America. It, however, is very good wildlife habitat and is very valuable for quick restoration along floodplains and other moist areas. It is also found inland, generally on the west side of the Rocky Mountains, in British Columbia, western Alberta, western Montana, and northern Idaho. Paper Birch. It is one of the largest of some 40 species of Populus and is the tallest, fastest-growing hardwood in the western United States. Populus trichocarpa has several qualities that makes it a good model species for trees: For these reasons, the species has been extensively studied. Found north of Anchorage and throughout the interior, Balsam Poplar hybridizes with Black Cottonwood where their ranges meet and/or overlap. Black Cottonwood                                 The Willow Family– Salicaceae, Populus balsamifera L. ssp. It can grow to 150’ (50m) or more and can live 200-300 years. Trichocarpa means with hairy fruits, referring to its fluffy seeds. Largest of all North American cottonwoods. Alder. The bark is rough and dark-colored, thus “black cottonwood”. An infusion of the bark was used for sore throats. Today Black Cottonwood is used for the interior layers of plywood and for paper products, especially high-grade book and magazine paper. Living trees are used as windbreaks. Description of Values. The variation within a specimen is as much as found between unrelated trees. Known also as balsam cottonwood, western balsam poplar, and California poplar, it grows primarily on moist sites west of the Rocky Mountains. Genome annotation was done primarily by the Joint Genome Institute, the Oak Ridge National Laboratory, the Umeå Plant Science Centre, and Genome Canada. Germination is epigeal (above ground). Variable nitrogen fixation in wild Populus. United States, WA, Mount Rainier National Park, Sunshine Point. 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. It is used for timber, and is notable as a model organism in plant biology. Names: Black Cottonwood is also known as Balsam Poplar. [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]. COTTONWOOD BARK CARVINGS David L. Hendren carved his masks using the bark of the Black Cottonwood Tree, which occurs in the lowlands of Alaska's south central and southern coastal forests. 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.
