The understory vegetation associated with maple can be quite different from that in adjacent conifer forests. To ensure a supply of maple seedlings, arrangements must first be made for collection of seed and for production of seedlings at a qualified nursery. Control of competing vegetation should improve on the low rates of establishment and slow growth observed for maple in the presence of dense understory vegetation. Survival, age and height distributions, and stocking of bigleaf maple (Acermacrophyllum Pursh) seedlings were studied in 1- to 250-year-old Douglas-fir (Pseudotsugamenziesii (Mirb.) With even-aged mixtures or short (less than 10 years) delays in bigleaf maple establishment, maple sawtimber can be harvested at the same time as associated conifers.

Bigleaf maple is second to red alder among native hardwood species in abundance and in commercial importance in the Pacific Northwest. Elevation Bigleaf maple usually grows at low to middle elevations (near sea level to 3000 ft) in the central part of its range. R.M. Because this species tends to establish in patches or clumps, it may be sensible to manage bigleaf maple in monospecific patches in mixture with other trees. Old or damaged trees commonly have serious defects caused by wood-rotting fungi, which invade through stem and branch wounds. Erect or Spreading and requires ample growing space. All viable seeds will germinate in the first year; delayed germination does not occur. The species is monoecious (individual flowers are either male or female, but both sexes can be found on … Stand Management Diameter growth of bigleaf maple is very responsive to increased growing space. With careful color selection, the straight-grained wood can be stained to resemble cherry. The trunk diverges into numerous long, thick vertical limbs. Tree Characteristics. Canadian Journal of Forest Research 20:259-266. The growth rings on the end grain are not very distinct; on the radial and tangential surfaces, however, the growth rings (diffuse porous) and are moderately small to medium in size. (50 to 1170 mm) during the growing season. The outstanding performance of bigleaf maple cultivated in nurseries and back yards indicates great potential for management of seedlings in the field. Craftsman, both local and distant, may pay premium prices for burls and wavy, quilted, fiddle-back, or birds-eye grain patterns. P. 33-40 in Silvics of North America, Volume 2, Hardwoods. It grows to be up to 35 meters tall, but more commonly 15-20 meters tall. Lumber is graded with the special NHLA rules for bigleaf maple; grades include Selects and Better, No. 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. A dense canopy of bigleaf maple will also suppress competing understory vegetation, reducing the need for other vegetation management treatments. Seeds ripen early in September and October, and are dispersed by the wind from October through January. NADKARNI, N.M. 1984 Biomass and mineral capital of epiphytes in an Acer macrophyllum community of temperate moist coniferous forest, Olympic Peninsula, Washington State.
