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).

Esthetics And Landscaping In Aspen: Ecology And Management In The Western United States, Craig W. Johnson, Thomas C. Brown, Michael L. Timmons
Aspen Bibliography
Aspen is valued for its scenic beauty. One indication of this is the trips to the "high country" that many forest visitors make to view the autumn color changes (fig. 1). Another is the frequency with which aspen is planted in urban and suburban areas. Subjective generalizations about the esthetic uses of aspen, although reasonable, provide only rough guidance for management of scenic quality. They can not be used to compare the relative beauty of different scenes, or to determine how much scenic beauty changes as the physical characteristics of the scene change, either naturally or as the result of …

Progeny Testing Of Native Aspens And Their Hybrids For Biomass Production In Michigan, G.L. Reighard, J.W. Hanover
Progeny Testing Of Native Aspens And Their Hybrids For Biomass Production In Michigan, G.L. Reighard, J.W. Hanover
Aspen Bibliography
Anaspen progeny test consisting of 206 families of trembling aspen (Populus tremuloides), bigtooth apsen (P. grandidentata), and their hybrids (P. Xsmithii and P. Xrouleauiana) was planted on five Michigan sites and evaluated after two growing seasons. Growth performance of trembling aspen families when compared with all aspen taxa was above average and increased with the latitude of the plantation site. Backcrosses of trembling aspen males to white poplar-bigtooth aspen (P. Xrouleauiana) females produced the fastest growing families at all Lower Peninsula plantations. Most hybrid aspen (P. Xsmithii) families had growth rates below the planation …

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

Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Clone Expansion And Competition Between Quaking And Bigtooth Aspen Suckers After Clearcutting, Donald A. Perala
Aspen Bibliography
The ability of quaking and bigtooth aspens (Populus tremuloids Michx., P. grandidentata Michx.) to vegetatively regenerate dense stands of root sprouts (suckers) is well documented (Brinkman and Roe 1975). Tens of thousands of suckers per hectare are commonly produced when stands are killed by fire or removed by clearcutting.
Cryptosphaeria Canker And Libertella Decay Of Aspen, Thomas E. Hinds
Cryptosphaeria Canker And Libertella Decay Of Aspen, Thomas E. Hinds
Aspen Bibliography
A recently discovered, widely distributed canker disease of aspen and other poplars throughout the Rocky Mountain region is described. Inoculations with ascospore and conidial isolates of Cryptosphaeria populina show the fungus is capable of causing branch, sprout, and sapling mortality, trunk cankers, and the discoloration and decay of aspen stems previously associated with its imperfect stage, Libertella sp. The greatest average canker elongation 50 mo after September inoculations was 33.5 cm with sapwood decay and discoloration extending to 401 cm. The fungus caused an average weight loss of 13.5% in bark, 27.0% in sapwood, and 19.1% in heartwood blocks. Incidence …

Estimating Plant Biomass For Undergrowth Species Of Northeastern Minnesota Forest Communities, L.F. Ohmann, D.F. Grigal, L.L. Rogers
Estimating Plant Biomass For Undergrowth Species Of Northeastern Minnesota Forest Communities, L.F. Ohmann, D.F. Grigal, L.L. Rogers
Aspen Bibliography
Knowledge of the plant biomass comprising a forest community is important to many aspects of multiple-use management. Direct measurement of biomass, however, is expensive and time-consuming to under-take each time biomass information would be useful. Fortunately, other measurements that can be made in the field less expensively or more easily can be used for estimating biomass.
