Biofuel Feedstocks: The Risk Of Future Invasions, Joseph M. Ditomaso, Jacob N. Barney, Allison M. Fox Nov 2007

Biofuel Feedstocks: The Risk Of Future Invasions, Joseph M. Ditomaso, Jacob N. Barney, Allison M. Fox

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

In an effort to decrease greenhouse gas emissions, expand domestic energy production, and maintain economic growth, public and private investments are being used to pursue dedicated feedstock crops for biofuel production. Unlike food crops grown for grain-based ethanol (e.g., corn), which require high inputs of fertilizers and pesticides and typically are grown on prime agricultural land, proposed lignocellulose-based energy crops (e.g., switchgrass) typically have a neutral or negative carbon budget, require relatively few economic or environmental inputs, and can be cultivated on marginal, lower-productivity land. Thus, a rapidly growing industry related to crop selection, cultivar improvement, and conversion technilogies is …

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 …

Cooperation And Coordination Are Invasive Species: Important For Effective Management Of Invasive Weeds, U.S. Government Accountability Office

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

Invasive weeds, native or nonnative plant species, cause harm to natural areas such as rangelands or wildlife habitat and economic impacts due to lost productivity of these areas. While the federal investment in combating invasive species is substantial most has been concentrated on agricultural lands, not on natural areas. In this report, GAO describes (1) the entities that address invasive weeds in natural areas and the funding sources they use; (2) federal, state, and local weed management officials’ views on the barriers to weed management; and (3) their opinions about how additional resources for weed management could be distributed. GAO …

Utah Wolf Management Plan, Utah Division Of Wildlife Resources Publication #: 05-17, The Utah Division Of Wildlife Resources, The Utah Wolf Working Group

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

This plan will guide management of wolves in Utah during an interim period from delisting until 2015, or until it is determined that wolves have established1 in Utah, or assumptions of the plan (political, social, biological, or legal) change. During this interim period, arriving wolves will be studied to determine where they are most likely to settle without conflict.

The goal of this plan is to manage, study, and conserve wolves moving into Utah while avoiding conflicts with the wildlife management objectives of the Ute Indian Tribe; preventing livestock depredation; and protecting the investment made in wildlife in Utah.

Big Sagebrush Response To One-Way And Two-Way Chaining In Southeastern Utah, John A. Fairchild, James N. Davis, Jack D. Brotherson, Usda Forest Service

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

A decadent, mixed stand of Wyoming big sagebrush, Artemisia tridentata wyomingensis, and mountain big sagebrush, Artemisia tridentata vaseyana, located north of Cisco, Utah, was subjected to one-way and two-way chaining treatments in November 1987. The effect of the treatments on plant community characteristics and shrub vigor was documented over a 3-year period. Stand density was reduced 60 percent on sites chained two ways and 43 percent on sites chained over once. Shrubs on one-way chained sites produced more leader growth in 1989 and 1990 than those on untreated sites or sites chained two ways. Browse production on one-way chained sites …

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

The Utah Natural Heritage Program (UNHP) assimilates and synthesizes information concerning rare species for use in land management and species conservation applications. This information is maintained in the UNHP database and includes both species-level information—e.g., assessments of species conservation status from a statewide perspective—and population-level information, which includes GIS coverages for species of high conservational interest. Beginning in 1996 an effort to develop information in the UNHP database for animal species was funded by the Utah Reclamation, Mitigation, and Conservation Commission under authority of the Central Utah Project Completion Act. Initial efforts focused on assigning conservation priority ranks. Several factors—comprising …

Status Of White-Tailed And Gunison's Prairie Dogs, Craig Knowles Nov 2002

Status Of White-Tailed And Gunison's Prairie Dogs, Craig Knowles

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

The status of the white-tailed and Gunnison's prairie dogs was investigated by conducting telephone interviews with agency people knowledgeable about these species within their area of jurisdiction. Available literature on prairie dog taxonomy, and life history and ecology was also reviewed. The white-tailed and Gunnison's prairie dogs are considered distinct species with no recognized subspecies. Both species are colonial, hibernate during the winter, and occur in shrub-grassland and grassland habitats in the Intermountain West. Density of white-tailed prairie dogs within colonies (2-5 prairie dogs per acre) is typically less than densities of Gunnison’s prairie dogs within colonies (5-10 prairie dogs …

The Invasion Of Western Waters By Non-Native Species: Threats To The West, Western Regional Panel On Aquatic Nuisance Species Sep 2001

The Invasion Of Western Waters By Non-Native Species: Threats To The West, Western Regional Panel On Aquatic Nuisance Species

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

The waters of western North America are being transformed by invasive aquatic plants, fish, and other animals from around the world. These plants and animals, which have been introduced both intentionally and accidentally by humans, can irrevocably alter our native ecosystems. While they may be harmless in their own waters, once brought into a new ecosystem where their native predators do not exist, they can harm native species by eating their food, preying on them, transmitting diseases to which the natives have no defenses, or (like many invasive aquatic plants) simply outgrowing them. Not all non-native species cause serious problems, …

Western Rangeland Noxious Weeds: Collecting, Sharing And Using Information, U.S. Department Of The Interior, Usda, Charles Valentine Riley Memorial Foundation

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

Western rangeland weeds such as yellow starthistle, leafy spurge, Canada thistle and Russian knapweed are causing tremendous losses to agricultural industries including both crop and livestock production. Concurrently, many public lands managed by federal agencies are being steadily invaded. As a result, these lands held in the public trust are experiencing reductions in commodity yields, recreational opportunities, biodiversity and ecosystem function. Consequently, every state in the West has noxious weed management programs that endeavor to enhance the financial and technical resources available for weed management and to assist in coordination across the diverse public and private land ownership mosaic common …


Selenium Poisoning Of Wildlife And Western Agriculture: Cause And Effect, N. E. Korte Feb 2000

Selenium Poisoning Of Wildlife And Western Agriculture: Cause And Effect, N. E. Korte

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

This project examined the hypothesis that selenium contamination is not the principal cause of the decline of endemic fish species in the Upper Colorado Basin. Activities employed to test this hypothesis included a reconnaissance of locations altered by recent road construction, a reinterpretation of available literature regarding selenium toxicity, and the interpretation of unpublished data obtained from the Upper Colorado Basin Fish Recovery Program. The project demonstrates that most of the evidence implicating selenium is circumstantial. Specifically, this research demonstrates that neither the historical record nor the technical literature consistently supports the emphasis given selenium toxicity. For example, many locations …

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

Across the United States, wildlife habitat has been substantially changed as human populations expand and land is used for human needs. These human uses and needs often compete with wildlife which increases the potential for conflicting human/wildlife interactions. In addition, segments of the public strive for protection for all wildlife; this protection can create localized conflicts between human and wildlife activities.


The Identification, Distribution, Impacts, Biology And Management Of Noxious Rangeland Weeds, Roger L. Sheley Oct 1994

The Identification, Distribution, Impacts, Biology And Management Of Noxious Rangeland Weeds, Roger L. Sheley

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

This document provides a discussion of the biology and management of exotic rangeland weeds which are a threat to native ecosystems of the western United States. Chapter 1 describes a generalized approach for managing noxious weed infested rangeland, while Chapter 2 focuses on preventing noxious weed invasion. In some cases, noxious weeds readily invade riparian areas, and because of the sensitive nature of these ecosystems Chapter 3 is devoted to riparian weed management. The following 13 chapters describe the identification, origin, history, distribution, potential invasion, impacts, biology and ecology, and management of specific noxious rangeland weeds.

Four species of prairie dogs are native to the plains and plateaus of the western United States. The most abundant and widely distributed of these is the blacktailed prairie dog, (Cynomys ludovicianus). This species has been a frequent topic of discussion at previous Great Plains Wildlife Damage Control workshops. Black-tailed prairie dog ecology and management was the topic of a panel discussion held at the Fifth Great Plains Wildlife Damage Control Workshop, in Lincoln, Nebraska (Timm and Johnson 1982) and the theme topic at the Eighth Great Plains Wildlife Damage Control Workshop in Rapid City, South Dakota (Uresk et al. …
