Trees are one of the dominant features of our existence on earth and play a fundamental role in the environment. This book aims to give the reader an overview and understanding of trees. Subject areas covered include ecology and conservation, tree anatomy and evolution, pathology, silviculture, propagation and surgery. Balsam poplar × black cottonwood hybrids have been reported in Alaska, British Columbia, and Alberta [28,49,57,73]. Hybrids with members of the Aigeiros section are also observed. Eastern cottonwood (P. deltoides var. occidentalis) × black cottonwood hybrids have been reported near Flathead Lake, Montana.
YNP maintains radio collars in all wolf packs within the park. Wolf Project staff monitor population dispersal, distribu-tion, reproduction, mortality, and predation on ungulates. Monitoring and management activities for the first two years of the project are documented in The Yellowstone Wolf Project, Biennial Report – Subsequent. Breton Island, lynx were found to be common over much of the island prior to bobcat colonization. Concurrent with the colonization of the island by bobcats, lynx densities declined and their presence on the island became restricted to the highlands, the one area where bobcats did not become established.

Picea glauca, the white spruce, is a species of spruce native to the northern temperate and boreal forests in North America. Picea glauca was originally native from central Alaska all through the east, across southern/central Canada to the Avalon Peninsula in Newfoundland.
It now has become naturalized southward into the far northern United States border states like Montana, Minnesota Family: Pinaceae.
Radial distribution of white spruce regeneration in mature aspen stands surrounding isolated spruce seed trees in two regions, Lac La Biche (open bars) and Whitecourt (hatched bars). In interior Alaska, where white spruce seed is their primary food, red squirrels harvested between 10% and 69% of cones during a "medium" cone production year.
One red squirrel may cache up to 16, cones per year. In mixedwood forest in Alberta, red squirrels harvested % ± % of the cone crop over a 3 year period.
In interior Alaska, the quantity of black spruce seed dispersed over 70 postfire days in a burned-over stand was times greater than that dispersed in an adjacent unburned stand.
How quickly cones open and release seed is apparently related to fire temperatures: High. Given the recent evidence for climate warming and permafrost degradation, the distribution of white spruce is expected to expand, but the transition from black to white spruce may be dispersal.
The stand initiation stage decisively influences future forest structure and composition, particularly in the boreal forest which is a stand replacement disturbance driven system. In boreal Alaska, the conventional forest management paradigm has focused on the production of large-dimension timber, particularly white spruce (Picea glauca).Cited by: 3.
Pinaceae -- Pine family Hans Nienstaedt and John C. Zasada White spruce (Picea glauca), also known as Canadian spruce, skunk spruce, cat spruce, Black Hills spruce, western white spruce, Alberta white spruce, and Porsild spruce, is adapted to a wide range of edaphic and climatic conditions of the Northern Coniferous Forest.
In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most elizrosshubbell.com some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height.
In wider definitions, the taller palms, tree ferns, bananas, and bamboos are also trees. fire in low-lying black spruce types. Tall blueberry willow seeded onto clearcut and burned white spruce floodplain forests in interior Alaska. Burning on these sites exposed much mineral soil, which provided excellent seedbeds for the invading willow.

Larch has also been used in herbal medicine; see Bach flower remedies and Arabinogalactan for details. In Central Europe larch is viewed as one of the best wood materials for the building of residences.
