Cottonwood and Balsam Poplar | Geophysical Institute

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.

Northern Tree Habitats - Geophysical Institute

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 ...

Tree Rings and History | Geophysical Institute

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 ...

More on Why Tree Trunks Spiral | Geophysical Institute

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.

The secret life of red squirrels | Geophysical Institute

Stan Boutin has climbed more than 5,000 spruce trees in the last 30 years. He has often returned to the forest floor knowing if a ball of twigs and moss within the tree contained newborn red squirrel pups. Over the years, those squirrels have taught Boutin and his colleagues many things, including an apparent ability to predict the future.

The Kodiak Treeline | Geophysical Institute

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.

Trees as Earthquake Fault Indicators | Geophysical Institute

Then using tree ring dating methods, it may be possible to date earthquakes occurring before historical records were kept. The ability to identify and date very large earthquakes occurring within the past thousand years is important in establishing earthquake risk and for predicting future earthquakes.

Orange trees in the Alaska Range | Geophysical Institute

It was a tree disease known as spruce needle rust, which infects only the current year’s needles of white, black and Sitka spruce trees. The orange powder is composed of millions of tiny spores, which the rust fungus uses to reproduce.
