Utah Prairie Dog Habitat Evaluation Guide, Natural Resources Conservation Service, Environmental Defense

All U.S. Government Documents (Utah Regional Depository)

The Utah prairie dog (Cynomys parvidens) (UPD) is listed as a threatened species under the Endangered Species Act (ESA) and exists only in southwestern Utah. UPD numbers and range have declined dramatically since settlement of Utah because of conversion of rangeland to cropland, urban development, fire suppression, improper grazing, drought, and introduced sylvatic plague (Yersina pestis). As of this writing, approximately 75% of all Utah prairie dogs inhabit private lands. This fact highlights the need to encourage farmers and ranchers to manage UPD habitat on their property in order to move the species closer to recovery. This guide provides technical …

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).

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 …

How To Reseed Utah Range Lands, A. Perry Plummer, Richard M. Hurd, C. Kenneth Pearse

Aspen Bibliography

Additional low cost forage is urgently needed by Utah's range livestock industry. Seeding of depleted tracts in accordance with recently developed methods and principles will help supply this forage and is entirely feasible. Where the value of the increased forage will repay the cost of planting, careful reseeding of selected sites is fully justified.

The important part that reseeding can play in restoring ranges to their former capacity has been demonstrated. Although satisfactory results can be obtained on many sites during average or better years, much more study is needed to insure consistent success in abnormal years and to extend …
