Environmental Considerations For The Proposed Goldfields Gas Pipeline Route Through Wanjarri Nature Reserve, H J. Pringle

Resource management technical reports

Provides a broad description of the biophysical environment on Wanjarri Nature Reserve, discusses land management hazards, assesses and suggests an alternative alignment for the proposed Goldfields Gas Pipeline and briefly discusses environmental monitoring.From a purely environmental perspective the optimal alignment for the proposed Goldfields Gas Pipeline might be to the east of the mulga plains, in the spinifex for most of the way, and west of the sand ridge field near the track down to South Bore.

Fage Determination Of Tropospheric Ho And Ho₂, Linda Acha George, Thomas M. Hard, Robert J. O'Brien

Environmental Science and Management Faculty Publications and Presentations

FAGE (fluorescence assay with gas expansion) was developed as a sensitive technique for the detection of low-concentration free radicals in the atmosphere. The application of FAGE to tropospheric hydroxyl (H0) and hydroperoxyl (H0₂) radicals has yielded calibrated measurements of both species in both clean air and highly polluted urban air. For HO calibration, a continuously stirred tank reactor provides a uniform external HO concentration, which can be measured by gas chromatography of an HO-reactive hydrocarbon. The aerodynamics of the air-sampling process has been modeled computationally, with results that agree with empirical observations of the effects of nozzle diameter on HO …

Predator Politics In Texas, Bill Sims

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The coyote (Canis latrans) is certainly one of the most destructive predators affecting the livestock industry, particularly sheep and goats. In fact, title of this session is very appropriate, because when you talk about “politics”, coyotes seem to have more politicians working for them than any other animal.

Predator Politics: Personal Thoughts And Perceptions, Milo J. Shult

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

My career as an extension wildlife specialist and a university administrator has allowed me to monitor both the public and private sectors' perspectives on coyotes (Canis latrans) and their associated management policies. Selected experiences described herein illustrate the problems (current and future) that characterize emotionally-charged conflicts like those typified by coyote control efforts.

Coyotes: A Matter Of Perspective, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Predators and predator management in general are always controversial topics. As with most controversies, both ends of an emotional continuum vie for the attention of the nonvocal, uncommitted majority. To provide unbiased information on the controversy surrounding coyotes (Canis latrans) in Texas, the Texas Agricultural Extension Service produced a 23-minute video in 1991. The video addresses both "sides" of the coyote "coin" while providing factual biological information on the topic. The video has been quite popular, and has received both state and national awards.

Coyotes In The Southwest: Foreword, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Long before the recent clamor over endangered species, predators and their management were controversial The coyote (Canis latrans) is often at the center of such debates. Cursed by some, revered by others, respected by all, the coyote is an icon of the Southwest.

The Livestock Protection Collar For Removing Depredating Coyotes: A Search For Perfect Justice?, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Lethal control techniques for controlling coyotes (Canis latrans) are often maligned as a means for resolving coyote depredations on domestic livestock. With the exception of the Livestock Protection Collar (LPC), lethal control methods (e.g., foot-hold traps and neck snares) lack the ability to specifically remove those coyotes actually preying upon livestock. The LPC capitalizes on attack behavior of coyotes to remove offending individuals. Although currently registered for use in 5 states, LPCs have been used routinely only in Texas. Success with LPCS involves an understanding of coyote behavior and proper targeting of collared livestock. LPCs have been used …

Historical Perspective On Coyote Control Methods In Texas, Robert L. Phillips, Gary L. Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

A variety of control methods used over an 80-year period (1915-1995) contributed to the effective and successful coyote (Canis latrans) damage management program that exists in Texas today. Traps, toxicants, shooting, denning, and dogs were important during the early years of the Texas Animal Damage Control Service (TADCS) program. Aerial hunting and snares evolved as important control tools following the ban on strychnine and Compound 1080 in 1972. The livestock protection collar (LPC) has received increased use in recent years and has been useful in resolving difficult depredation problems. ADC policy along with changing state and federal regulations …

Public Attitudes Toward Predators In Texas, Douglas Reiter, Mark W. Brunson, Robert H. Schmidt

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

A national survey of public attitudes to ward wildlife damage management provided the opportunity to extract a data set from Texas respondents on predator management Texas respondents were generally more supportive of predator control for livestock protection than the rest of the U S., although the overall trends were similar. Lethal technologies scored low on a humaneness scale.

The Re-Establishment Of The Coyote In The Edwards Plateau Of Texas, Gary Lee Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

In the early 1900s organized predator control was initiated to remove coyotes (Canis latrans) and wolves (C. lupus and C. rufus) from the sheep and goat producing areas of Texas. Operations were begun in the Edwards Plateau, the largest area of sheep concentration. By the 1920s, many of the inner Edwards Plateau counties were considered to be almost free of coyotes and wolves In the 1950s coyotes and wolves were extirpated from most of the Edwards Plateau After a coyote population irruption in the early 1960s, coyotes began to re-establish themselves on the periphery of the …

Sheep And Goat Losses In Relation To Coyote Damage Management In Texas, Gary Lee Nunley

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The average reported sheep and goat loss to coyotes (Canis latrans) in 1992 on those properties worked by the cooperative animal damage control program were relatively low. Sheep and goat losses were not evenly distributed among the producers. Geographical distribution of the losses reflected a positive relationship between relative coyote density and livestock losses. The sheep and goat industry is adversely affected by the cumulative losses of those producers suffering high levels of predation.

Coyotes In The Rolling Plains Of Texas, Wyman P. Meinzer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Coyotes (Canis latrans) in the Rolling Plains region of Texas have experienced several factors in the last 40 years that may have possibly influenced population dynamics and feeding niche. The 3 most important changes were (a) the demand for coyote pelts during the 1970s, (b) a region-wide growth of the stocker cattle industry and (c) the increasing incidence of sarcoptic mange. The availability of stocker cattle carcasses may be providing a source of dependable food during a previously stressful period, thus inflating coyote survival and abundance superficially relative to traditional cow/calf ranching areas Sarcoptic mange has been present …

Immunocontraception As A Tool For Controlling Reproduction In Coyotes, Lowell A. Miller

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The development of immunocontraception as a tool for population management of coyotes (Canis latrans) and reduction of coyote predation may provide an environmentally safer alternative to pesticides. Because they are proteins, immunocontraceptive vaccines do not persist in the environment or bioaccumulate in the food chain. The National Wildlife Research Center (NWRC) will examine the effects (immunological, hormonal and behavioral) of treating penned coyotes with 2 immunocontraceptive vaccines: porcine zona pellucida (PZP) and gonadotropin releasing hormone (GnRH). Initial studies will be conducted using traditional subcutaneous injections; however, the goal IS to develop an orally-deliverable immunocontraceptive vaccine as an alternative …

Managing For Coyotes To Enhance Waterfowl Production: An Alternative Perspective, Terry A. Messmer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The Prairie Pothole Region (PPR) of North America produces about half of the continent's duck population. Predation on hens, young, and eggs severely impacts duck production In the region decreasing fall flights. Recent studies conducted in the region suggest that management efforts to increase duck production need to consider both habitat and predator effects. Research indicates that managing on the landscape level to protect coyotes in sufficient numbers to exclude red foxes should be encouraged in PPR areas suitable for duck production and where the risks of damage to domestic livestock and other wildlife species are minimal.

The Coyote In Southwestern Folklore, Wyman P. Meinzer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Perhaps one of the first mentions of the coyote (Canis latrans) by Anglos in early-day journalism was from Mask Twain's notes during his travels through the plains frontier in the early- to mid-19th century. Touring the frontier region before its inevitable subjugation to ranching and farming, Twain wrote of the coyote and its larger more infamous cousin, the wolf(C. lupus), In words which left no doubt to the reader the popular sentiments for such predators of the day Although derogatory in some respects, Twain did concede respect for Canis latrans and made mention of the tricks …

Coyotes In The Southwest: Dedication To Samuel L. Beasom, Dale Rollins

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

This symposium is dedicated to the life, achievements and memory of Samuel L. Beasom. From the first time that I considered trying to assemble this symposium, Sam Beasom was on my list of key people to include. Sam's professional contributions and his dry wit would surely play a pivotal role in a conference on coyotes in the Southwest, especially one to be conducted in Texas. I never dreamed then that his contributions, and subsequent recognition, would be presented posthumously here today.

Photographing Coyotes, Wyman P. Meinzer

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

Wildlife photography has become an increasingly popular hobby over the last 10 years. Coyotes (Canis latrans) are among the more difficult animals to photograph under natural field conditions (i.e., in the "wild"). For studying and photographing coyotes behaving routinely, I recommend the use of a "draw station" (i.e., cow carcass) and a blind that will all low relatively close inspection of coyote interactions.

Disease And Coyotes In Texas, Danny B. Pence

Coyotes in the Southwest: A Compendium of Our Knowledge (Symposium Proceedings, 1995)

The coyote (Canis latrans) population in southern Texas has a recurring group of 3 common helminthes and several peripheral species of lesser importance. Although recurrent group analyses have not been applied to other macro- or microparasite communities, there are certain infectious agents with high prevalences that could form recurrent groups, and that are potentially important in tams of impacting host population (ie , coyote) abundance. While the current rabies epizootic involving coyotes in southern Texas is of public health concern, it probably will not have a major impact on the coyote population. Most likely, the net effect of …

Hot Topic: Implications of FERC Order No. 636 for the Natural Gas Industry.

After one year of natural gas pipeline deregulation, what impact has Order No. 636, issued by the Federal Energy Regulatory Commission in 1992, had on the natural gas industry - specifically, pipeline and local distribution companies? What additional changes might occur? Elisabeth Pendley, of KN Energy and the NRLC 1995 El Paso Natural Gas Law Fellow, will discuss the dramatic changes to the natural gas industry caused by FERC Order No. 636.

Foraging Behaviors Of Snowy Egrets (Egretta Thula) And Yellow-Crowned Night-Herons (Nyctanassa Violacea) In South Louisiana, D. Tommy King, Dwight Leblanc

United States Department of Agriculture Wildlife Services: Staff Publications

We report two previously undescribed foraging techniques used by Snowy Egrets (Egretta thula) and Yellow-crowned Night-Herons (Nyctanassa violacea) to catch crawfish (Procambarus spp.). Snowy Egrets were selecting crawfish that had recently molted their shells and Yellow-crowned Sight-Herons were targeting crawfish that were emerging from their burrows. These observations were conducted on commercial crawfish ponds near Catahoula, LA, USA.

Federal Commodity Programs And Returns To Irrigation In The West, Marcel P. Aillery, Economic Research Service, Natural Resources And Environment Division

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

This report examines the impact of Federal commodity programs on returns to irrigation in the western United States. Returns to irrigation are defined as average returns to land, management, fixed capital, and water (above variable water cost), net of returns to dryland crop alternatives. Commodity market returns and program revenues per unit of applied irrigation water are estimated by field crop and subregion. Two representative study years - 1984 and 1987 - highlight the effect of differing commodity prices and program support levels under extreme market conditions. Aggregate returns to irrigation in western field-crop production were fairly constant over the …

A Decision Model For Environmental Assessment Of Process Waste Products, Kyle F. Byard

Theses and Dissertations

Environmental managers must compare the potential impacts of waste products when deciding upon courses of action. The estimation and comparison of these impacts is a subjective process, and few methods of comprehensive, quantitative comparison of waste products currently exist. The intent of this study is to develop a decision methodology to evaluate the environmental impacts of waste products and to score them for comparison. The method will follow established system design principles and incorporate significant characteristics of the waste material. Scores derived to represent the environmental impacts of materials will then he analyzed employing statistical and probabilistic methods to assess …
