Aspen Bibliography

Western wildlands are covered by a broad spectrum of vegetation zones, from dense forests to barren deserts.


Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch Jan 1988

Breeding Birds In Uncut Aspen And 6- To 10-Year-Old Clearcuts In Southwestern Colorado, V.E. Scott, G.L. Crouch

Aspen Bibliography

Numbers of breeding birds were estimated for various sizes and ages of clearcuts, for edge habitat created by the clearcuts, leave strips between clearcuts, and uncut aspen forest (controls). Total numbers of birds were not different among three size classes or five age classes of clearcuts. Total were lower on clearcuts than on edges but not different from controls or leave strips.

Response Of Breeding Birds To Commercial Clearcutting Of Aspen In Southwestern Colorado [Usa], V.E. Scott, G.L. Crouch Aug 1987

Response Of Breeding Birds To Commercial Clearcutting Of Aspen In Southwestern Colorado [Usa], V.E. Scott, G.L. Crouch

Aspen Bibliography

Breeding birds on an aspen forest in southwestern Colorado increased in species diversity after 25% of the timber sale area forest was clearcut in patches of 3 to 20 acres. Bird population density on the forest with clearcuts was not significantly different from that on an uncut forest. Of the 20 species evaluated, six were more and one was less abundant than on the uncut forest.


Aspen Sucker Damage And Defect In Colorado Clearcut Areas, Thomas E. Hinds, W.D. Shepperd Jan 1987

Aspen Sucker Damage And Defect In Colorado Clearcut Areas, Thomas E. Hinds, W.D. Shepperd

Aspen Bibliography

Substantial acreages of aspen in the Rocky Mountains are being regenerated by clearcutting; however, there is little information on the quality of the suckers that reestablish in these areas. Whether the new stands will be more or less defective than their predecessors is unknown.

Aspnorm: A Normal Diameter Distribution Growth And Yield Model For Aspen In The Central Rocky Mountains, H.T. Mowrer Jan 1986

Aspnorm: A Normal Diameter Distribution Growth And Yield Model For Aspen In The Central Rocky Mountains, H.T. Mowrer

Aspen Bibliography

Development of a normal diameter distribution growth and yield model for pure, even-aged, unthinned clones of aspen in the central Rocky Mountains is described, including testing for normality of diameter distributions, development of regression estimators for stand parameters, model validation, and model application.

Diseases In Aspen: Ecology And Management In The Western United States, Thomas E. Hinds Jan 1985

Diseases In Aspen: Ecology And Management In The Western United States, Thomas E. Hinds

Aspen Bibliography

Although many diseases attack aspen, relatively few kill or seriously injure living trees. The common leaf diseases, in general, are widely distributed throughout the range of aspen, whereas there are subtle differences in distribution between the important decay fungi, and apparently entirely different areas of distribution of major canker-causing organisms. However, there still are large gaps in knowledge of the disease organisms and their influence on natural and regenerated stands.


Wildlife In Aspen: Ecology And Management In The Western United States, Norbert V. Debyle Jan 1985

Wildlife In Aspen: Ecology And Management In The Western United States, Norbert V. Debyle

Aspen Bibliography

Aspen forests provide important habitat for many species of wildlife (Gullion 1977b), especially in the West (see the appendix to this chapter). In the coniferous forests of the interior West, aspen groves may be the only source of abundant forage; in the grasslands they may be the sole source of cover. A primary value of the aspen ecosystem in the West during the past century has been production of forage for both wildlife and domestic livestock (see the FORAGE chapter).

Natural genetic interchange and extensive colonization of aspen by seed strongly depends upon favorable climatic and microclimate conditions and upon human intervention.

Wood Resource In Aspen: Ecology And Management In The Western United States, J.R. Jones, N.V. Debyle, R.P. Winokur

Aspen Bibliography

Aspen has not been cut extensively in the West; in fact, it has been grossly underutilized. For example, as recently as 1975, the aspen harvest from National Forests in four Forest Service regions in the Rocky Mountain area was 7.64 million board feet.1 Additional minor volumes were cut on special-use permits for products such as fuel and corral poles. The total amount cut represented only 0.1% of the net volume available in these aspen forests.

Genetics And Variation In Aspen: Ecology And Management In The Western United States, J.R. Jones, N.V. Debyle Jan 1985

Genetics And Variation In Aspen: Ecology And Management In The Western United States, J.R. Jones, N.V. Debyle

Aspen Bibliography

The broad genotypic variability in quaking aspen (Populus tremuloides Michx.), that results in equally broad phenotypic variability among clones is important to the ecology and management of this species. This chapter considers principles of aspen genetics and variation. variation in aspen over its range, and local variation among clones. For a more detailed review of the genetics of qualung aspen, especially with wider geographic application and with emphasis on tree breeding, see Einspahr and Winton (1976).


Wood Utilization In Aspen: Ecology And Management In The Western United States, E.M. Wengert, D.M. Donelly, D.C. Markstrom, H.E. Worth Jan 1985

Wood Utilization In Aspen: Ecology And Management In The Western United States, E.M. Wengert, D.M. Donelly, D.C. Markstrom, H.E. Worth

Aspen Bibliography

In the past, markets for quaking aspen timber from the Rocky Mountains have been insufficient to support significant harvesting. This shortage of markets severely restrained the potential for aspen management. As a result, many stands protected from wildfire gradually reverted to conifers (see the VEGETATIVE REGENERATION and FIRE chapters).

The rotation, in forestry, is the planned number of years between formation of a crop or stand and its final harvest at a specified stage of maturity (Ford-Robertson 1971).
