Northern Tree Habitats - Geophysical Institute
11 Jan 2025 at 7:11am
However, after seven growing seasons in Fairbanks, trees from the most northern homelands of the Dezadeash, Carmacks and Mayo areas of the Yukon are among the tallest, and the early starters from the south are now ranked at the bottom; although some of the trees from the Ft. Nelson area of British Columbia have maintained their relatively fast ...
Cottonwood and Balsam Poplar - Geophysical Institute
12 Jan 2025 at 10:30am
The Klukwan giant holds the national record for black cottonwood diameter. Its nearest rival, a tree near Salem, Oregon, does hold the national height record. The Klukwan giant belies the belief that trees tend to get smaller the farther north one goes. Both balsam poplar and cottonwood have value for fuel wood, pulp and lumber.
Burls - Geophysical Institute
16 Jan 2025 at 7:48am
Trees with burls seem to be found in a cluster; if one tree in an area has burls, it is likely that other trees around it has them too. This clumping is suggestive of leafhoppers or aphids transmitting the disease, but no conclusive evidence of this is known yet. Burls weaken trees but do not kill them.
More on Why Tree Trunks Spiral - Geophysical Institute

Granted, not all trees exhibit the same twist, but the majority of them do. The phenomenon can be likened to the claim that water will always spiral out of a drain in a counter-clockwise direction in the northern hemisphere. It is well known that you can make it spiral out in either direction, if you give it a little shove first.

Spruce trees planted on the islands by the Russians in 1805 are doing just fine and reseeding themselves naturally, although the total tree population hardly amounts to a forest. In recent years, trees have been planted at military bases along the chain, and the State is now shipping out seedlings for reforestation projects all over Alaska.
Black Spruce - Geophysical Institute
11 Jan 2025 at 6:38pm
Black spruce are the climax trees on cold, poorly drained soils in Alaska and Yukon. They rarely exceed 45 feet (15 meters) in height or 9 inches (23 centimeters) in diameter. In a typical stand, the diameter of most trees is less than 5 inches, and growth is very slow. Half the trees in a 30-year-old stand may be less that 2 inches in diameter.
Feltleaf willows: Alaska?s most abundant tree

Tree line changes on the Kenai Peninsula | Geophysical Institute
13 Jan 2025 at 2:39pm
The changes in Kenai Peninsula trees might be due to the milder weather the peninsula, along with most of Alaska, has experienced since about 1977, when ocean-surface temperatures in the North Pacific warmed. Climatologists with the Alaska Climate Research Center report that the Homer area warmed 4.2 degrees Fahrenheit on average from 1949 to 2007.
The majesty and mystery of Alaska yellow cedar
12 Jan 2025 at 11:02pm
These trees, which can live longer than 1,000 years, grow on the rainy coast from the Oregon/California border through British Columbia and as far north as Prince William Sound. The giants have in many areas died in large numbers, puzzling scientists who later came up with a non-intuitive theory of what killed them.
Witches' Broom - Geophysical Institute
14 Jan 2025 at 2:24pm
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.
