Betula alleghaniensis).
Some trees take on more refined, subtle shades, such as yellow birch (
Betula alleghaniensis) with its beautiful yellow foliage, or the common beech (Fagus sylvatica), which turns a glorious shade of copper.
Some trees take on more refined, subtle shades, such as yellow birch (

In this research, water-based and solvent-based coatings were applied to edge-glued panels of yellow birch (
Betula alleghaniensis Brit.).
Yellow birch,
Betula alleghaniensis, is one of some 60 species of birch from around the world, and grows in Canada, the Great Lakes region and New England, and as far south as North Carolina.
Moose used balsam fir, eastern hemlock, and red maple proportionally more than their availability, used sugar maple (Acer saccharum), yellow birch (
Betula alleghaniensis), and mountain ash (Sorbus americana) proportionally less than their availability, and used striped maple, beaked hazel (Corylus cornuta), and mountain maple (Acer spicatum) proportional to their availability.
The Birch Bottom-land is dominated by
Betula alleghaniensis and B.
With a greenhouse experiment we investigated these relationships by examining responses of growth, growth-related morphology, survival, and their interrelationships to a range of nitrogen (3.4 X [l0.sup.-9]-3.4 X [l0.sup.-3] mol/L N fertilizer solutions) and low light (0.6-7.3% of open sky) availabilities for young seedlings of 10 North American tree species that vary in observational shade tolerance rankings and seed size (Populus tremuloides, Betula papyrifera,
Betula alleghaniensis, Acer saccharum, Larix laricina, Pin us banksiana, Pinus resinosa, Pinus strobus, Picea mariana, and Abies balsamea).
The Tellico area was dominated by northern hardwoods (oak, Quercus spp.; hickory, Carya spp.; yellow popular, Liriodendron tulipifera; black cherry Prunus serotina; yellow birch,
Betula alleghaniensis; American beech, Fagus grandifolia; sugar maple, Acer saccharum; and mountain maple, A.
saccharum,
Betula alleghaniensis, Fraxinus americana, and Tsuga canadensis.
Upland areas are generally mixed hardwood forests with multiple tree species including American beech (Fagus grandifolia Ehrh.), sugar maple (Acer saccharum Marsh.), yellow birch (
Betula alleghaniensis Britton), red pine, eastern white pine, jack pine (Pinus banksiana Lamb.), black spruce (Picea mariana (Mill.) B.S.P.), and balsam fir (Abies balsamea (L.) Mill.) (USFWS, 2009).
