Type Variability And Succession In Rocky Mountain Aspen, Walter F. Mueggler

Aspen Bibliography

Most of the 6 million acres of aspen lands in the West occur in the Central Rocky Mountains. The ability of western aspen to occupy a wide diversity of sites, the great genetic diversity among clones, and the role of aspen as both a dominant successional and stable species severely complicate management. Such ecological and genetic diversity results in considerable variability in both resource production and potential response to management. Progress in classifying the ecological variability of aspen lands is slow; useful partitioning of genetic diversity is nil.

Kiln Drying Characteristics Of Studs From Rocky Mountain Aspen And Wisconsin Aspen, James C. Ward

Aspen Bibliography

Aspen studs, 7/4-inch thick, from Rocky Mountain and Wisconsin trees will dry to required moisture contents within similar periods of time under conventional and high temperature kiln schedules. Bacterial wetwood occurs in both Rocky Mountain and Wisconsin aspen and causes severe drying problems from wet pockets, collapse, honeycomb, and ring failure. Presorting green lumber is a suggested solution to the wetwood problem.

Aspen Mortality In Rocky Mountain Campgrounds, Thomas E. Hinds

Aspen Bibliography

Aspens die from canker disease infections as a result of mechanical injuries to the live bark inflicted by thoughtless campers. Dead trees usually are cut to reduce camper hazard. Aspen loss is related to campground age. A desirable aspen-type camp unit can be degraded to a treeless site of grass, forbs, and shrubs within 10 to 20 years. The management of aspen campgrounds must be altered if the resource is to be maintained.

Effects Of Clear-Cutting On Nutrient Losses In Aspen Forests On Three Soil Types In Michigan, Curtis J. Richardson, Jeffrey A. Lund

Aspen Bibliography

The effects of clear-cutting on NO^-₃, NH⁺₄, PO^3-₄, K⁺, Ca²⁺, Na⁺, Fe²⁺, and Mg²⁺ losses were evaluated in three 60-year-old aspen stands in northern lower Michigan.

Bird Populations Of Aspen Forests In Western North America, J.A. Douglas Flack

Aspen Bibliography

The patterning of populations of plants and animals is probably the result of selection over time of organisms according to their individual physiological tolerances, behavioral adaptations to an environmental complex, and geographical availability (Gleason 1926).

Preliminary Forest Habitat-Types Of Northwestern Utah And Adjacent Idaho, Jan A. Henderson, R.L. Mauk, D.L. Anderson, R. Ketchie, P. Lawton, S. Simon, R.H. Sperger, R.W. Young, A. Youngblood

Aspen Bibliography

Following pioneering work in northern Idaho and eastern Washington by Daubenmire 1952, 1968, and later in Montana, Idaho, Wyoming and Utah by Pfister et al., 1974, Steele et al., 1974, 1975, Cooper 1975, Reed 1969, Ream 1964, and Pfister 1972, work was begun to finish identifying and naming the forest habitat types of Utah. Preliminary work had been done by Pfister (1972) on the subalpine fir and engelmann spruce series. This current work covers all forest land in Utah and adjacent southern Idaho including that covered by Pfister.

Field work in northewestern Utah and adjacent Idaho began in …

Perspective On Particleboards From Populus Spp., Robert L. Geimer

Aspen Bibliography

Populus species particleboards have a high compression ratio resulting in high bending strength. Their low-porosity edges, advantageous in furniture manufacture, dictate close moisture content control in production.

Aspen roundwood is the primary raw material for composition structural sheathing. Populus utilization will likely increase as material sources expand and as new product develop.

Frost Damage In Poplar On The Prairies, Harry Zalasky

Aspen Bibliography

Frost cankers in poplar are freeze-killed areas of bark and wood around which woody calluses develop and form buris and frost ribs. Frost dieback is a freeze-killed segment of the stem at the base, tip, or mid-portion of a branch or leader. It may or may not enhance natural pruning or poplar branches depending on whether the basal parts are damaged or alive and able to form abscission layers. In addition to abscission, low temperature affects increment, growth patterns, and vigor of poplar. Tree become stunted from persistent leader dieback. Suckers, crooks, and sweeps also characterize many stands of poplar. …

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.

Aspen Potential - A Land Manager's Viewpoint, Bruce B. Hronek

Aspen Bibliography

From a land manager's viewpoint, the management of aspen has been lacking. However, the potentials of aspen as a viable and meaningful species that will contribute much to the forest environment and economics is both possible and practical.

Aspen Forest After Harvest, Norbert V. Debyle

Aspen Bibliography

Aspen is a unique forest tree with respect to regeneration. It produces abundant root suckers, up to 40,000 per acre are common, after clearcutting or fire removes the parent stand. The rapidly growing sucker stand competes well with other vegetation, but is susceptible to destruction by excessive ungulate browsing. Clearcut areas produce more streamflow and more growth on shrubs and herbaceous vegetation than does the uncut forest. The patchwork of age classes that results from even-age management optimizes wildlife habitat requirements for several desired species.
