Interior alaskan forests have only six native tree species: white spruce, black spruce, quaking aspen, balsam poplar, larch (tamarack) and paper birch. northern canadian forests have all of those, plus jack pine, balsam fir and lodgepole pine. since northern canada and interior alaska share the same grueling climate and extremes of daylength, why are the canadian tree species absent from.

I eventually found a tree with a spiral lightning mark and it followed the spiral grain exactly. one tree, of course, proves nothing. "but why should the tree spiral? more speculation here: foliage tends to be thicker on the south side of the tree because of better sunlight. A tree near one of our campsites had a crack at its base through which we could pass the folded saw. yet the tree was still alive, with just one rope of cambium — the outer bark that transports water and nutrients — snaking up the trunk. a few of its blue green feathery leaves flagged from the top of what otherwise looked like a snag. A citizen friendly pocket sized book in kannada describes commonly found avenue trees, filling the paucity of such resources in the local language while also.

Witches' broom on spruce trees is caused by a rust disease (a kind of fungus disease). the rust lives on the spruce tree throughout the year. each spring, small yellow pustules appear on the new needles of the broom. a strong sweet odor, which is easily recognizable, usually accompanies the maturation of these pustules. Burls, spherical woody growths on the trunks of spruce, birch and other trees, are commonly found throughout wooded parts of alaska. A tree's age can be easily determined by counting its growth rings, as any boy or girl scout knows. annually, the tree adds new layers of wood which thicken during the growing season and thin during the winter. these annual growth rings are easily discernible (and countable) in cross sections of the tree's trunk. in good growing years, when sunlight and rainfall are plentiful, the growth rings. The most plentiful moose food in the state — and probably alaska’s most numerous tree — is the feltleaf willow, which was once called the alaska willow. as its name implies, the feltleaf sprouts canoe shaped green leaves that feel fuzzy on the underside.
