Hydrologic Recovery Of Aspen Clearcuts In Northwestern Alberta, R H. Swanson, R L. Rothwell
Hydrologic Recovery Of Aspen Clearcuts In Northwestern Alberta, R H. Swanson, R L. Rothwell
Aspen Bibliography
A 3-year study of evapotranspiration from aspen clearcuts 1 to 14 years of age indicated the following: (1) The annual evapotranspiration from 1- to 5-year-old clearcuts ranges from 0 to 143 mm less than a mature forest on the same site. Evapotranspiration is highly dependent upon the amount of precipitation. (2) These effects can vanish in as few as 2 years with low precipitation (300 mm) or persist for 40 to 45 years with high precipitation (600 mm). These results were confirmed by data from the Spring Creek experimental watershed. Simulated water yield increase from the harvested catchment averaged 16 …
Logging In Alaska's Boreal Forest: Creation Of Grasslands Or Enhancement Of Moose Habitat, William B. Collins, Charles C. Schwartz
Logging In Alaska's Boreal Forest: Creation Of Grasslands Or Enhancement Of Moose Habitat, William B. Collins, Charles C. Schwartz
Aspen Bibliography
Timber harvest in Alaska’s boreal forest can greatly enhance or severely reduce moose (Alces alces) habitat quality, depending on forest management objectives, timing and methods of harvest, and post-logging site preparation. Overstory removal associated with timely exposure of mineral soil favors establishment of early successional hardwoods important as moose browse. A combination of clear-cutting and soil scarification on mesic sites mimics fire, windfall, and fluvial erosion, important natural forces that drive regeneration of the boreal forest. When cut during dormancy, aspen (Populus tremuloides) and balsam poplar (P. balsamifera) Regenerate prolifically by root and stump …

Aspen Bibliography
Quaking aspen (Populus tremuloides Michx.) stands in Arizona, Colorado, New Mexico, Utah, and Wyoming (fig. 1) contain an estimated 7.1 billion bd ft of sawtimber (Green and Setzer 1974).
Problems And Opportunities Associated With Aspen Logging Systems, Wendell H. Groff
Problems And Opportunities Associated With Aspen Logging Systems, Wendell H. Groff
Aspen Bibliography
The opportunities in equipment selection, production ranges and specialization available to a logger producing volume from a coniferous species in many cases are not available to an aspen logger. The logger must identify the limiting factors and design a logging system accordingly.
Yields From 18-Year-Old Aspen Via Total Tree Harvesting, M.K. Benson, D.W. Einspahr
Yields From 18-Year-Old Aspen Via Total Tree Harvesting, M.K. Benson, D.W. Einspahr
Aspen Bibliography
Described are the results of harvesting the above-ground parts of an 18-year-old aspen stand and the observations made on the initial suckering of the new stand. The yields for the stand of 17.7 cunits per acre were greater than predicted yields of comparable material for the site at age 35. Suckering on the area the first area after cutting averaged 37,000 aspen stems per acre and 2.6 feet in height.

Aspen Minnesota's No. 1 Tree, George Rossman, Bob Rossman, Allen Rossman
Aspen Bibliography
For thousands of years after the last glaciers disappeared from northern Minnesota, the forces of nature worked to develop a magnificent forest of predominantly white and red pine. Stands of big pines covered more than 5 million acres.

Logging Methods And Peeling Of Aspen, T. Schantz-Hansen
Logging Methods And Peeling Of Aspen, T. Schantz-Hansen
Aspen Bibliography
The logging of forest products is influenced by many factors, including the size of the trees, density of the stand, the soundness of the trees, size of the area logged, topography and soil, weather conditions, the degree of utilization, the skill of the logger and the equipment used, the distance from market, etc. Each of these factors influences not only the method of logging but also the costs. The purpose of this paper is not to cover in detail the effect of each of these variations, but to deal with some of the major problems typical to logging aspen. Well …
