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.

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 ...
Tropical Fossils in Alaska - Geophysical Institute
20 Nov 2024 at 2:22am
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

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.
Feltleaf willows: Alaska?s most abundant tree

The range of the feltleaf willow, probably the most numerous tree in Alaska. From Alaska Trees and Shrubs by Les Viereck and Elbert L. Little, Jr.
The majesty and mystery of Alaska yellow cedar

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.

These exotic trees ? some now 70 feet tall ? are a nice legacy for the men who planted shin-high seedlings years before Woodward last visited the plot in 1981. Les Viereck, a renowned ecologist who wrote Alaska Trees and Shrubs, died in 2008.
Southcentral Alaska: a Natural Experiment in Plant Succession
24 Nov 2024 at 6:49am
About 9,100 years ago, white and black spruce trees made it to Southcentral. Ager said the winged seeds of both tree species probably blew down through mountain passes from the unglaciated Interior. Once white and black spruce made it through the Alaska Range, the trees migrated southward at a rate of eight-tenths of a kilometer per year.
Witches' Broom - Geophysical Institute
23 Nov 2024 at 12:55pm
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.
