- Northern Tree Habitats - Geophysical Institute
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
- 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
- Tropical Fossils in Alaska - Geophysical Institute
In contrast, the equatorial and tropical rain forests may contain as many as 3000 different species in an area no larger than one square mile Trees of the rain forest tend to have smooth bark, broad evergreen leaves and heavily buttressed roots--all suitable characteristics for a climate where water and sunshine are plentiful all year round
- 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
- 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
- The largest black spruce in Alaska | Geophysical Institute
The tallest trees are not always the winners of The Big Tree Challenge; foresters score trees on height, circumference and the spread of a tree’s crown The black spruce on the UAF campus is taller than the state record western paper birch, a 67-footer near Haines, and Alaska’s tallest balsam poplar, a 60-foot tree on the Kuskokwim River

- Orange trees in the Alaska Range | Geophysical Institute
While wandering middle Alaska this summer, I noticed orange spruce trees along the entire length of the Denali Highway, from Paxson to Cantwell In what looked like a dendrological case of frostbite, tips of every branch were afflicted with something The real show happened when the wind blew: An entire valley glowed apricot
