Comparison Of Water Dynamics In Aspen And Conifer: Implications For Ecology Water Yield Augmentation, Eric Martin Lamalfa

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Differences in water dynamics between deciduous aspen (Populus tremuloides) and co-occurring evergreen conifer species in the Northern Rocky Mountains result from complex physical and biological interactions. A comprehensive evaluation of individual water transfer mechanisms was used to elucidate the relative importance of several components of the hydro logic cycles of aspen and conifer, and determine which water transfer mechanisms have potential to cause differences in net water yield.

Adjacent aspen and conifer stands were monitored to determine snow accumulation and ablation (snow survey), soil moisture recharge (capacitance probes), snowpack sublimation (sublimation pan), transpiration period (thermal dissipation probes), and …

Some Environmental Relationships Of Undergrowth Species In Aspen Communities Of The Intermountain West, W F. Mueggler

Aspen Bibliography

This analysis results from an opportunity to explore plant-environmental relationships from data collected for a different purpose. Origin of the data is a study designed to develop an aspen community-type classification for southern Idaho, western Wyoming, Utah, and Nevada which resulted in the publication "Aspen Community Types of the Intermountain Region" GTR INT-250 by W.F. Mueggler (1988).

Restoration Of Aspen In Different Stages Of Mortality In Southern Utah, Seth Ray Ohms

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Aspen clones of an aspen-dominated community in Southwestern Utah are declining, some having experienced high mortality coupled with in sufficient regeneration. The objectives of this study were to (I) determine if decadent, non-regenerating mature aspen stands could be regenerated through disturbance of the 111 auxin/cytokinin hormone relationship by clearcutting; (2) determine the extent of ungulate use of regenerating aspen ramets. Clearcuts were made in late summer of 2001 in 10 different clones that exhibited various levels of decline on a continuum from relatively healthy to extremely deteriorated. Nested wildlife/livestock exclosures were constructed in each clearcut plot, as well as in …

First-Year Postfire And Postharvest Soil Temperatures In Aspen And Conifer Stands, Michael C. Amacher, Amber D. Johnson, Debra E. Kutterer, Dale L. Bartos

Aspen Bibliography

Aspen (Populus tremuloides Michx.) stands are in decline throughout the Interior Western United States because of fire suppression, overbrowsing by domestic livestock and native ungulates, and forest succession. We measured summertime soil temperatures in stable aspen, decadent aspen, and mixed aspen/conifer stands; a mixed aspen/conifer clearcut; as mixed aspen/conifer forest that was burned in a lightning-caused fire; and a decadent aspen stand and mixed aspen/conifer stand that received prescribed burns. Soil temperature fluctuations and mean soil temperatures were greater in cut and burned areas than in untreated stands. In untreated stands, mean soil temperature increased in the order: mixed …

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.

Forest Insect And Disease Management : Aspen Mortality At The Maroon Lake Campground, David W. Johnson, Thomas E. Hinds

Aspen Bibliography

At the request of the White River National Forest, Dave Johnson, Plant Pathologist, FI&DM and Tom Hinds, Plant Pathologist, RMFRES, made an evaluation of aspen mortality in the Maroon Lake Campground, Aspen Ranger District during June 13 to 15, 1977. Previously, Hinds (1976) reported accelerated aspen loss in 17 campgrounds, including Maroon Lake, located throughout Colorado and New Mexico (Fig. 1).

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.

Ecological Aspects Of Air Pollution From An Iron Sintering Plant At Wawa, Ontario, A.G. Gordon, E. Gorham

Aspen Bibliography

At Wawa, in northern Ontario, vegetation has been damaged severely by sulphur dioxide pollution from an iron-sintering plant. Damage is mainly restricted to a narrow strip northeast from the sinter plant, since southwest winds are strongly predominant. It is traceable from the air for at least 20 mile in this direction and is estimated as severe within 11 miles and very severe within 5 miles. Within about 10 miles NE, from the sinter plant ground flora variety declines markedly, from about 20-40 species per 40 square meter quadrat beyond this distance to 0-1 species within 2 miles of the pollution …

The Aspens: Their Growth And Management, William Grant Weigle, Earl Hazeltine Frothingham

Aspen Bibliography

The aspens, or "popple," as they are often collectively termed, occupy a peculiar position in the forests of North America. Growing up rapidly and in great abundance over areas which have been deforested, usually by fire, they attain only a small size, produce a soft, weak wood, extremely valuable for a limited number of uses, and die at a relatively early age.
