Bigleaf maple seedling establishment and early growth in Douglas-fir forests. To maintain moderate crowding, stands should not be opened too much initially. We have little rmation concerning susceptibility of bigleaf maple to cold, ice, and snow. Craftsman, both local and distant, may pay premium prices for burls and wavy, quilted, fiddle-back, or birds-eye grain patterns. Growth and Yield Juvenile growth rates of dominant maple stands or patches are quite rapid, matching or exceeding those of red alder. Learn how Bigleaf can help you ensure resilient and reliable application performance, no matter where you are on your Cloud journey. Burns and B.H. The leaves are simple, opposite, and very large between fifteen to thirty centimeters wide and almost as long (Farrar 1995). Although much of the wood is straight-grained, some highly figured wood that includes wavy, quilted, fiddle-back or birds-eye grain patterns is also produced. As with other fine-grain, hardwoods, surface scratching associated with sanding (swirls and cross-grain) can be a problem, although not to the same degree as with the hard maples. While it is not as strong as the eastern hard maples, it performs better in most tests than the soft maples. Skip to main content.us Hello, Sign in. BIGLEAF MAPLE, OREGON MAPLE. The understory vegetation associated with maple can be quite different from that in adjacent conifer forests. It grows best on deep, well-drained soils with abundant moisture, conditions that occur most commonly on river terraces, flood plains, and seepage areas. The tree likes Sun to half-shade at the location and the soil should be all permeable soils, floodplains, tolerates soil lacking in … Thinning and vegetation management may be needed to maintain adequate space for the growth of bigleaf maple. Herbaceous associates include maidenhair fern, western swordfern, ladyfern, red woodsorrel, false lily-of-the-valley, prince’s-pine, spreading sweetroot, and twinflower. Yields of about 4500 ft3 per acre were estimated for 70-year-old stands of pure bigleaf maple in British Columbia. I used a paired plot design to evaluate the influence of mature bigleaf maple on the growth and G��-߱~)�.�. Although some forest nurseries are producing bigleaf maple on a trial basis, commercial supplies of maple seedlings are not consistently available. Roundheaded borers often damage the wood of dead and dying trees. See Appendix 1, Table 3, for average mechanical properties for small clear specimens. Powderpost beetles (Ptilinus basalis) may rapidly infest dead trees or lumber that is improperly stored. Survival, age and height distributions, and stocking of bigleaf maple (Acer macrophyllum) seedlings were studied in 1- to 250-yr-old Douglas fir (Pseudotsuga menziesii) stands in western Oregon to identify the stages in stand development in which bigleaf maple is most likely to establish successfully from seed. It originally comes from Western North America. The Bigleaf maple is botanically called Acer macrophyllum. Management may greatly improve the quality of stems from sprouts of bigleaf maple. FRIED, J.S., J.C. TAPPEINER II, and D.E. Bigleaf maple appears to be somewhat tolerant of wet conditions, as indicated by its shallow, spreading root system and its common presence in wet areas. Old or damaged trees commonly have serious defects caused by wood-rotting fungi, which invade through stem and branch wounds. The greatest abundance of bigleaf maple is in the foothills of the Cascade and Coast ranges. Average temperatures range from a minimum of 28°F (January) to a maximum of 81°F(July). Bigleaf maple will establish and grow on a wide variety of sites, including relatively harsh, dry areas in southwestern Oregon; however, growth and stem form may be poor. about the bigleaf maple dieback issue, has raised awareness of another pathogen affecting bigleaf maple in California. Root pathogens (Armillaria spp.) Insects and Diseases Young, undamaged trees are generally free of serious disease or decay. The Tree is a deciduous tree, it will be up to 30 - 40 m (99 - 131 ft) high. Erect or Spreading and requires ample growing space. Unlike the standard NHLA grading rules, these grasdes are generally based on the best face of the piece.

Call us at 1 315 4971058. All viable seeds will germinate in the first year; delayed germination does not occur. Bigleaf maple is second to red alder among native hardwood species in abundance and in commercial importance in the Pacific Northwest. To maintain stem quality in plantations, seedlings may need to be protected from deer, planted in high densities, and correctively pruned. Drying and Shrinkage Under properly controlled conditions, bigleaf maple can be successfully kiln-dried in a short time with a minimum of degrade.

In their natural habitat, bigleaf maples are found most commonly in the forest or on forested slopes. 1 Common or Better green lumber from bigleaf maple logs (80 percent and 58 percent for grade 1 and 2 logs, respectively) that is quite good compared to other hardwoods (Appendix 1, Table 2). These values are the same as those of black cherry, and are better than those of red alder (radial 4.2 percent, tangential 7.3 percent) and Oregon white oak (radial 4.4 percent, tangential 9.0 percent). It is native to western North America, mostly near the Pacific coast, from southernmost Alaska south to … It usually grows from near the Pacific Ocean to a maximum of 186 miles inland. The foliage and young stems of bigleaf maple are preferred browse for elk and deer, and these animals often use saplings for rubbing antlers. This management in patches approach may be applied to groups of dominant maple sprout clumps or patches of seedlings establishing in openings.
