Frost Damage In Poplar On The Prairies, Harry Zalasky Jan 1976

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. …


Aspen Forest After Harvest, Norbert V. Debyle Jan 1976

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.

Aspen Potential - A Land Manager's Viewpoint, Bruce B. Hronek Jan 1976

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.

Perspective On Particleboards From Populus Spp., Robert L. Geimer Jan 1976

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.

Problems And Opportunities Associated With Aspen Logging Systems, Wendell H. Groff Jan 1976

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 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 …


Aspen Mortality In Rocky Mountain Campgrounds, Thomas E. Hinds Jan 1976

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.

Aspen Resource In The Southwest, Darrell W. Crawford Jan 1976

Aspen Resource In The Southwest, Darrell W. Crawford

Aspen Bibliography

There is a relatively large source of unused aspen in the Southwest. If markets can be developed, there are challenging opportunities to utilize more of this fiber. Most aspen in the Southwest is classified in the marginal component because of steep slopes, accessibility and low market values. To meet the logging constraints of this component is a real challenge to prospective purchasers. However, commercial opportunities are feasible on the Carson, Santa Fe, Apache and Kaibab National Forests.
