Miscellaneous observations

warty = red elderberry shreddy = silver maple (broad, often diagonal), ironwood (narrower strips, vertical), white elm (a little) plates peeling off at edges = sugar maple, red maple purplish brown with white horizontal lenticels = Japanese lilac evergreen with purplish hue = hemlock narrow, high intersecting ridges with broader valleys = Siberian elm and other elm broader ridges intersecting, yellow brown bark = eastern cottonwood diamonds, esp at base = ashes white, nonshredding, black triangles beneath branches = European birch white bandaged tree = trembling aspen, poplar rocky mountains with yellow lichen in valleys = black walnut dark peeling birch-like = European buckthorn orange, especially higher up on branches = Scotch pine harlequin black and white plaques = Ponderosa pine spongy ridges = hackberry pinstripe = younger Norway maple bronze = flowering crabapple cracking and shredding even on small trees = flowering crabapple cracking in young trees = honey-locust beige bark with paler unattractive striae = Manitoba maple old elephant lumpy warty skin = Manitoba maple - big older trees dark, smooth and even but with small darker areas and "claw-scratches" of pale = purpleleaf sandcherry (Cis)

Observed types of bark

Linear strips of bark, loosening at sides or top and bottom Silver maple = loosens somewhat at top and bottom; often light grey Red maple = can be identical; maybe strips are somewhat shorter Sugar maple = more irregular and loosens from the sides Slippery elm = can look very similar to either; strips seem thinner and flatter. Look for more typical elm basket-weave diagonal strips near base, sometimes present Corduroy bark Eastern cottonwood = mature trees heavily furrowed well up into tree Oak = elevations are flattened somewhat; continues well up into tree Linden = looks more like slit with knife in many cases Norway maple = more pinstriped than curderoy Willow E-mail error reports.
