Yields From 18-Year-Old Aspen Via Total Tree Harvesting, M. K. Benson, D. W. Einspahr Jun 1972

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 year after cutting averaged 37,000 aspen stands per acre and 2.6 feet in height.

The Influence Of Atmospheric Dust And Foliar Leachates On The Chemical Quality Of Throughfall In Northern Utah, Dennis R. Parent May 1972

The Influence Of Atmospheric Dust And Foliar Leachates On The Chemical Quality Of Throughfall In Northern Utah, Dennis R. Parent

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the summer of 1971 a research project was carried out in an attempt to determine the influence of dust and leachates on rainfall quality. Open precipitation collectors, collectors under polyethylene screens, collectors under Douglas-fir (Pseudotsuga menziesii) and juniper (Juniperus scopulorum), and leaf analyses were used to determine the relative effects of these two processes by which chemicals are incorporated into the rainwater. All samples were analyzed for sodium (Na+), calcium (Ca++), magnesium (Mg++), potassium (K+), and available phosphorus. Under the trees, sodium concentrations increased as much as …

Forest Fuel Accumulation -- A Growing Problem, Marvin Dodge Jan 1972

Forest Fuel Accumulation -- A Growing Problem, Marvin Dodge

The Bark Beetles, Fuels, and Fire Bibliography

Discusses the problem caused by accumulation of forest fuels in the wild-land forests of the western USA under the policy of total fire protection pursued there for many years, and emphasizes the need to find economical and practical ways of reducing fuel hazards in these forests, especially by means of prescribed burning under conditions in which low-intensity fires can be achieved.

Management For Deer, John D. Byelich, Jack L. Cook, Ralph I. Blouch Jan 1972

Management For Deer, John D. Byelich, Jack L. Cook, Ralph I. Blouch

Aspen Bibliography

Deer in the Lake States are declining. Early stages of second growth forest following the logging era favored deer. Aging and successional changes toward more tolerant types are causing range deterioration. Aspen is the major deer-producing forest type. Commercial harvest of aspen improved deer range, but not enough is taking place to reverse the downward trend of deer or to save the type from conversion. Additional efforts to cut of otherwise treat aspen stands specifically for deer have been of token size. Michigan has earmarked a deer license increase for range improvement and is now embarked on a large scale …

Stemflow In A Multi-Storied Aspen Community, J.R. Clements Jan 1972

Stemflow In A Multi-Storied Aspen Community, J.R. Clements

Aspen Bibliography

This report presents results of a stemflow study in a 5-year-old, dense, sucker stand of largetooth aspen [Populus grandidentata Michx.]. The purposes of this study were to determine the relation of stemflow volume per tree to gross rain per storm, to determine the proportion of gross rain reaching the ground as stemflow, and to derive an equation to predict rain equivalent of stemflow from gross rain for use in other studies of water relations of this sucker stand.

Guide To The Identification Of Poplar Cultivars On The Prairies, K. J. Roller, D. H. Thibault, V. Hildahl

Aspen Bibliography

This paper provides those who work with poplars in the prairies region of Canada with an easy-to-use leaf and twig key and detailed morphological descriptions of the more commonly planted cultivars. Recommendations for their use, notes on growth, natural pruning, susceptibility to insects and diseases, and tolerance to climatic extremes are also provided.


Aspen Minnesota's No. 1 Tree, George Rossman, Bob Rossman, Allen Rossman Jan 1972

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.

Simulation Of The Daily Growth Of An Aspen Population From The Measured Co2-Exchange Rates Of The Components, G.C. Bate, D.T. Canvin Jan 1972

Simulation Of The Daily Growth Of An Aspen Population From The Measured Co2-Exchange Rates Of The Components, G.C. Bate, D.T. Canvin

Aspen Bibliography

The daily total CO2-exchange of an aspen population (32 trees) was measured using a growth chamber gas analysis system which had been shown to measure accurately the actual carbon gain of the population. The CO2-exchange rates of the components (e.g. roots, stems, leaves) were measured in the light and dark and these rates were used to calculate the total CO2-exchange of the population using a computer model. The carbon gain during the photoperiod was underestimated by 25% in the simulation while the carbon loss during the nyctoperiod was overestimated 100% by the simulation.

Effect Of An Aspen Clearcutting On Water Yield And Quality In Northern Minnesota, Elon S. Verry Jan 1972

Effect Of An Aspen Clearcutting On Water Yield And Quality In Northern Minnesota, Elon S. Verry

Aspen Bibliography

The impact of different forest types on streamflow or groundwater recharge must be considered in evaluating multiple-use alternatives. The impact of species conversion on streamflow has been directly measured at the Coweeta Experimental Watersheds in North Carolina. However, the use of net precipitation1 data, with appropriate cautions, provides a practical basis for estimating water yield differences between forest types where long-term streamflow comparisons are not available.
