Efficacy Of Aluminum Phosphide For Black-Tailed Prairie Dog And Yellow-Faced Pocket Gopher Control, P. Rodger Moline, Stephen Demarais
Efficacy Of Aluminum Phosphide For Black-Tailed Prairie Dog And Yellow-Faced Pocket Gopher Control, P. Rodger Moline, Stephen Demarais
Great Plains Wildlife Damage Control Workshop Proceedings
The efficacy of aluminum phosphide was tested on a total of 300 active black-tailed prairie dog (Cynomys ludovicianus) mounds and 68 active yellow-faced pocket gopher (Pappogeomys castanops) tunnels during June-August, 1986 on the southern Great Plains in Lubbock County, Texas. Efficacy of aluminum phosphide was higher than controls (P < 0.001) for both species. Efficacy was higher for black-tailed prairie dogs (94.7 - 96.0%) than for pocket gophers (61.5 - 85.7%). Soil porosity and moisture appeared to influence efficacy for yellow—faced pocket gophers.
Current And Future Status Of Rodenticides And Predacides, Steve Palmateer
Current And Future Status Of Rodenticides And Predacides, Steve Palmateer
Great Plains Wildlife Damage Control Workshop Proceedings
I appreciate the opportunity to convey the current and future status of rodenticides and predacides at this workshop. According to the computer, the Agency has 2,888 products classified as vertebrate control agents. The Federal Insecticide, Fungicide, and Rodenticide Act tends to clump all vertebrate pesticides as rodenticides. This includes fish toxicants such as TFM; bird toxicants and repellents such as Starlicide and Avitrol; dog repellents such as lemongrass oil; bat toxicants and repellents such as naphthalene; commensal rodent toxicants such as warfarin, diphacinone, bromadiolone, brodifacoum, and red squill; field use rodenticides for many species (e.g., prairie dogs, ground squirrels) using …
Involving The Public In Prairie Dog Management On The Nebraska National Forest, George Probasco
Involving The Public In Prairie Dog Management On The Nebraska National Forest, George Probasco
Great Plains Wildlife Damage Control Workshop Proceedings
Scoping is the formal name for a process designed to identify public issues and incorporate public values into the decision making process for management of public lands. Scoping ensures that a public agency, in this case the Nebraska National Forest, will identify important issues and develop alternative management strategies for projects in full public view. Scoping has specific and fairly limited objectives: (a) to identify the affected public and agency concerns; (b) to facilitate an efficient analysis of the environmental impacts; (c) to define the issues and alternatives that will be examined in detail; and (d) to make sure that …
Fencing Methods To Control Big Game Damage To Stored Crops In Wyoming, John F. Schneidmiller
Fencing Methods To Control Big Game Damage To Stored Crops In Wyoming, John F. Schneidmiller
Great Plains Wildlife Damage Control Workshop Proceedings
Fighting damage to stored crops by big game animals is both costly and time consuming. Fencing methods are the most suitable means to prevent big game damage to stored crops. Experimentation in fencing methods is ongoing to find the best and most cost effective solution to this problem.
Small Mammals: Pests Or Vital Components Of The Ecosystem, Carolyn Hull Sieg
Small Mammals: Pests Or Vital Components Of The Ecosystem, Carolyn Hull Sieg
Great Plains Wildlife Damage Control Workshop Proceedings
Small mammals regarded as "pests" should not be viewed separately from other components in the ecosystem. Small mammals have significant influences on vegetation and soils, exert predatory pressure on other animals, and provide food for predators. Future management efforts should include consideration of these diverse influences.
Predator Management To Increase Duck Nest Success, Harold A. Doty, Anthony J. Rondeau
Predator Management To Increase Duck Nest Success, Harold A. Doty, Anthony J. Rondeau
Great Plains Wildlife Damage Control Workshop Proceedings
Operational programs of seasonal predator management to increase duck production may be economically feasible. Mammalian predators of nesting ducks and their eggs were reduced in numbers on selected areas of west central Minnesota during the nesting seasons 1982-86. Where predators were removed, nest success averaged 30% while nest success on nearby untreated habitat was 10%.
Why Do Possums Survive Aerial Poisoning Operations?, D. R. Morgan, C. L. Batcheler, J. A. Peters
Why Do Possums Survive Aerial Poisoning Operations?, D. R. Morgan, C. L. Batcheler, J. A. Peters
Vertebrate Pest Conference Proceedings: 12th (1986)
Major causes of failure of aerial poisoning operations against possums identified were: sublethal toxic loading, undersize sublethal baits, nonlearned behavioral aversion to 1080, and failure to encounter bait. Dislike of bait was not a major cause of failure. Progress has been made towards solving these problems, but failure to encounter bait remains a likely major reason for possums surviving aerial poisoning. Improvements in the aerial sowing of bait are essential if the full benefit of this progress is to be realized.
Plagues Of The House Mouse In South Eastern Australia, Glen Saunders
Plagues Of The House Mouse In South Eastern Australia, Glen Saunders
Vertebrate Pest Conference Proceedings: 12th (1986)
Plagues of the house mouse (Mus musculus) occur at irregular intervals throughout the agricultural regions of south-eastern Australia. This paper discusses these phenomena in terms of their impact on agricultural production, previous attempts to reduce damage and levels of infestation, and associated environmental implications. Consideration is also given to the accurate prediction of mouse plagues and the control strategies which need to be in place if effective management is to become a reality.

Tao How? Asian Religions And The Problem Of Environmental Degradation, Philip Novak
Tao How? Asian Religions And The Problem Of Environmental Degradation, Philip Novak
Collected Faculty and Staff Scholarship
"Twenty-five years ago, Huston Smith wrote an article called Tao Now 1 to enlist the help of traditional Chinese attitudes toward nature in expanding the West's environmental awareness. If my interrogative betrays a greater diffidence than his imperative, it is only because China, the land of the Tao, lacks an enviable environmental record. Sadly, it seems that the existence of noble cultural ideals regarding the environment, in India as well as China, have not been a sufficient gurantee of good stewardship." ~ from the article
Seepage Interceptor Drains And Topsoil Salinity, T R. Negus
Seepage Interceptor Drains And Topsoil Salinity, T R. Negus
Journal of the Department of Agriculture, Western Australia, Series 4
The Department of Agriculture established 121 trials in its Narrogin advisory district starting in 1972 to measure the effect of bulldozer and grader built seepage interceptor banks and drains on the topsoil salinity of the land downslope of them.
After 14 years of moniterin, there was no evidence that seepage interceptor drains and banks reduced the top soil salinity on 10 of the 11 sites in the Pingelly, Brookton and Wickepin Shires.

Licensing Of The U. S. Maritime Personnel: The International Impacts, Warren G. Schneeweis
Marine Affairs Theses and Major Papers
This paper examines the international and Federal efforts to enhance safety at sea and the protection of the marine environment through the development of standards to improve the training and strengthen the professional qualifications of seafarers. Special regard is made to the International Convention on Standards of Training, Certification and Watchkeeping for Seafarers, 1978, signed by the United States in 1979, and to the proposed amendments to the Federal regulations for licensing U. S. maritime personnel which will bring the U. S. licensing scheme in general conformance with that Convention. This research should lessen resistance to U. S. ratification of …
Broadacre Pest Control After Ddt, P J. Michael
Broadacre Pest Control After Ddt, P J. Michael
Journal of the Department of Agriculture, Western Australia, Series 4
DDT may no longer be applied to broadacre crops grown in Western Australia. It is being replaced by other more effective chemicals and with new methods of pest control. DDT was the most effective chemical for the control of several major broadacre pests in this State and farmers may well wonder why this change was necessary and how they will manage without DDT.
Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar
Forest Conservation In Nepal: Encouraging Women's Participation, Augusta Molnar
Poverty, Gender, and Youth
This issue of SEEDS focuses on ways in which women have been involved in a government forest conservation and restoration program in Nepal. As is common with many large-scale projects with a general impact, women were not a direct focus of the project's original design. As activities got underway, however, both the Nepali staff and their expatriate colleagues quickly realized that the direct involvement of women was crucial to the success of the project's participatory strategy. Over the initial five years, 1980 to 1985, a number of approaches to addressing women's needs and generating their active participation were tried. The …
Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter
Dust Elimination From Outdoor Feedlots For Sheep, D J. Carter
Journal of the Department of Agriculture, Western Australia, Series 4
The humble woodchip, widwly used as a soil mulch in Western Australian gardens, is set tto take a new role as a dust inhibito in assembly yards used to hold live sheep for export.
Research by the Department of Agriculture's Soil Conservation Service Branch has shown that, of the materials tested, woodchips were the most effective in preventing dust being generated. Wind speeds had to approach a "near gale" before dust developedfrom the protected soil.
The use of woodchips, therefore, provides a practical alternative to stabalising the soil and preventing an environmental problem associated with one of the State's valuable …
An Assessment And Comparison Of Hazardous Waste Management Hessen, Frg And Ontario, Canada, Elaine F. Collis
An Assessment And Comparison Of Hazardous Waste Management Hessen, Frg And Ontario, Canada, Elaine F. Collis
Theses and Dissertations (Comprehensive)
Hazardous waste management has recently become an issue of great concern for governments in industrialized countries. In spite of this, no one country has established a successful framework which guarantees the safe handling and disposal of hazardous wastes. The ideal system would generate no hazardous wastes in the first place but this, of course, is wishful thinking for highly industrialized societies. The next best or “preferred” solution is a system which emphasized reduction and recycling of hazardous wastes. The existing waste management systems in the world today, however, almost exclusively emphasize treatment and disposal. This thesis assesses the hazardous waste …
