Aspen In A Changing Climate, S.C. Zoltai, T. Singh, M.J. Apps
Aspen In A Changing Climate, S.C. Zoltai, T. Singh, M.J. Apps
Aspen Bibliography
In western Canada, aspen attains its best growth potential in the boreal zone under the present climatic conditions. The anticipated climate change within the next century, caused by anthropogenic actions, would result in a warmer climate and precipitation patterns similar to the present. Comparable conditions existed in western Canada during the mid-Holocene warm-dry period (about 6000 years ago), when grasslands and aspen parklands occurred far north of their present extent. The anticipated climate change would cause increased drought conditions in the south and a longer growing season in the north. Under such conditions aspen is expected to respond with generally …

Approximately 2.8 million ha of woodlands dominated by quaking aspen (Populus tremuloides Michx.) are scattered throughout the Western United States (Green and Van Hooser 1983).

The Impact Of Aspen Harvesting On Site Productivity, David H. Alban
The Impact Of Aspen Harvesting On Site Productivity, David H. Alban
Aspen Bibliography
Aspen management can affect site productivity in two major ways: First, aspen accumulates large amounts of nutrients (especially Ca) in its biomass. Harvesting removes these nutrients from the site and, in the long run, site quality will decline if these nutrients are not replenished. Second, the harvesting operation itself can cause site quality loss through soil physical disturbance or through accelerated soil organic matter decomposition and nutrient leaching losses. Our understanding of the processes controlling site productivity is very weak, therefore our ability to predict the consequences of management activities on site productivity is very limited. Current research will help …

Fungi Associated With Sprout Mortality In Aspen Clearcuts In Colorado And Arizona, W.R. Jacobi, W.D. Shepperd
Fungi Associated With Sprout Mortality In Aspen Clearcuts In Colorado And Arizona, W.R. Jacobi, W.D. Shepperd
Aspen Bibliography
Four aspen stands with greater than 90% sprout mortality in Colorado and one in Arizona were evaluated for fungal pathogens. There 4- to 5-year-old sprouts had rapidly expanding cankers moving from the terminal to the ground line. Roots of sampled sprouts showed no damage and root diseases were not found. Fruiting structures of Cytospora chrysosperma were consistently found on dying stems, while those of Dothiora polyspora were occasionally found. The same organisms were isolated from the margins of advancing cankers. Pathogenicity tests using greenhouse-grown aspen trees indicated C. chrysosperma caused rapidly expanding cankers similar to those observed on the aspen …

Mixed Conifer And Aspen Regeneration In Small Clearcuts Within A Partially Harvested Arizona Mixed Conifer Forest, P.F. Ffolliott, G.J. Gottfried
Aspen Bibliography
Southwestern mixed conifer forests are found on high-elevation sites, generally above 8,000 feet, throughout Arizona, New Mexico, and southwestern Colorado.
