Cottonwood and Balsam Poplar - Geophysical Institute
18 Nov 2024 at 8:25pm
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.
Feltleaf willows: Alaska?s most abundant tree

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 ...

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.
Tropical Fossils in Alaska - Geophysical Institute

Paleobotanist Jack A. Wolfe of the United States Geological Survey at Menlo Park, California, has found a number of tropical rain forest fossils along the eastern Gulf of Alaska. These include several kinds of palms, Burmese lacquer trees, mangroves and trees of the type that now produce nutmeg and Macassar oil.

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.
Burls - Geophysical Institute
14 Nov 2024 at 12:52pm
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.
Tree line changes on the Kenai Peninsula | Geophysical Institute
8 Nov 2024 at 5:13am
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.

Gregory and Wilson found that trees in both areas formed the same number of tracheids but that the white spruce in Alaska produced most of these cells in about one-half as much time as it took the trees in Massachusetts. In other words, the cambium in Alaskan trees was producing tracheids at a rate twice that of the Massachusetts trees.
Trees as Earthquake Fault Indicators - Geophysical Institute
13 Nov 2024 at 9:35pm
Trees along faults often are killed by drowning because the faults tend to collect normal drainage water. In some instances, there are widespread tree kills caused by general subsidence. Killed by sinking caused in the great 1964 Alaskan earthquake, firmly stark forests of dead trees stand guard around the shore of upper Turnagain Arm, near ...
