A Hydrology Temperature Model For A Small Mountain Watershed, Charles Wilson Pettee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A small mountain watershed located in the Wasatch Mountains of North Central Utah is calibrated to a lumped, deterministic simulation model which is capable of predicting daily streamflow and stream temperature. The input information required is daily precipitation and maximum and minimum air temperatures.

In this study, the area of watershed modeling is reviewed in general and as it specifically applies to the study watershed.

The degree of correlation between observed data and predicted output is only mediocre. The model remains unverified for streamflow prediction and is poorly verified for stream temperature.

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.

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 …

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).

Understory Production Not Predictable From Aspen Basal Area Or Density, K.E. Severson, J.J. Kranz

Aspen Bibliography

Analysis of effects of aspen basal area and density on production of understory vegetation revealed no useful predictive relationships using the model log Y = a + bX. However, as the proportion of ponderosa pine basal area increased in aspen-pine stands, understory production declined in a predictable manner. Root biomass, total biomass, and/or growth rate of aspen may be more closely related to understory production than measures of aspen overstory.

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.

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.

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.
