Emergency Rabid Skunk Control In Montana, Kenneth Seyler, Carter Niemeyer

Vertebrate Pest Conference Proceedings: 6th (1974)

A maximum of 500 strychnine eggs were placed in designated skunk habitat within a three mile radius where rabid skunks were diagnosed as an emergency control method to reduce or prevent the spread of rabies in striped skunk (Mephitis mephitis) populations in Northeastern Montana. The effects of strychnine on skunk and other non-target species populations were evaluated. When placed in primary skunk habitat, the toxicant eggs were selective in removing striped skunks. Scent post surveys indicated that skunk populations were reduced, while non-target species populations remained stable or increased in control areas. The effects of the toxicant egg …

Trapping: A Continuous Integral Part Of A Rodent Control Programme, H.R. Shuyler, R.F. Sun Jr.

Vertebrate Pest Conference Proceedings: 6th (1974)

Trapping is usually considered a rodent control technique of minor importance. Due to the economic situation in the Dumaguete, Philippines program from which this report is drawn, regular trapping was a biological necessity. Four species of rodents and a shrew were of concern. A continuing daily trapping program was developed from a field study of trap bait acceptability. Trap baits were reused every 23 days. Alternate baits were selected. Trap usage techniques were designed to optimize the results. Trap-bait shyness and trap shyness effects were observed but were not a major problem.

Animal Damage Control Research–"Are Present Priorities Based On Actual Need?", Richard N. Smith

Vertebrate Pest Conference Proceedings: 6th (1974)

Priorities regarding Bureau of Sport Fisheries and Wildlife vertebrate damage control research are in most cases based on actual need. Need is influenced by economic, political, legislative, and biological incentives. These incentives affect private industry, state and local governments, academia, and the federal government but in different ways. The Bureau of Sport Fisheries and Wildlife has 24 percent of its wildlife research budget invested in vertebrate damage control research. Its programs deal with predators, birds, and small mammals and research programs are problem oriented. Priorities are generally developed within the organization and are usually determined by biological need.

Experiments With Sounds In Repelling Mammals, John L. Stewart

Vertebrate Pest Conference Proceedings: 6th (1974)

Since its introduction for use in repelling birds , a number of people have found that Av-Alarm is effective for control of certain mammals. This includes not only those familiar to North Americans (deer, elk , coyotes), but also various less familiar species, even anthropoids (baboons) and bats. A number of example cases are described. A concept theory is presented in order to explain why certain sounds are more effective than others, and why sounds originally meant for bird control are also effective with mammals. The theory helps to predict untested situations , and also suggests when complex repelling sounds …

A Safe Approach To Natural Home Ranges, As Applied To The Solution Of Edge Effect Subjects, Using Capture-Recapture Data In Vole Populations, Ryo Tanaka

Vertebrate Pest Conference Proceedings: 6th (1974)

Capture-recapture work was performed in 1970 and 1971 with Microtus montebelli seeking to disclose the edge effect subjects. For the purpose, in principle, it is needful for us to approach the reality of home range in size and shape. As the result of these studies, it has been established that the method using observed range length and width is highly available for searching after natural ranges and that the natural range of the voles (Microtus and Clethrionomys) is ordinarily on the order of 0.05 for females and of 0.10 for males in acres and generally oblong in shape such as …

Recent Changes In Federal Bird Control, Gene H. Wilson

Vertebrate Pest Conference Proceedings: 6th (1974)

Probably the most significant changes in U. S. Fish and Wildlife Service legislation that might have an effect on those engaged in animal control work would have to do with the Migratory Bird Treaty Act, the Fish and Wildlife Act of 1956 recently amended, and one piece of proposed legislation which I'll mention at closing.

In March 1972, an amendment to our treaty with Mexico became effective. And more recent, the Fish and Wildlife Act of 1956 had a section added to it having to do with airborne hunting.

About two years ago, the amendment to the Mexican treaty added …

Rabies Vector Control In Alberta, J.B. Gurba

Vertebrate Pest Conference Proceedings: 6th (1974)

Following the last serious outbreak of rabies in 1952-57, the province of Alberta remained virtually free of the disease for 13 years. In 1970 a sudden increase occurred with 16 cases in various species. The Alberta Central Rabies Control Committee was reactivated to cope with the situation. Pre-immunization of high risk personnel and domestic pets was initiated along with supportive research to monitor infection rates in various species. Vector control programs were established to stop the spread of rabies by known wildlife vectors, particularly skunks (Mephitis mephitis) which had brought rabies across the great plains to the Alberta-Saskatchewan …

Feral Hogs-Boon Or Burden, Daniel C. Pattern

Vertebrate Pest Conference Proceedings: 6th (1974)

Feral hogs (Sus scrofa L. ) have long been considered a pest by most land managers because of the potential range and pasture damage that can result from their feeding habits. In recent years however, second only to deer, feral hogs have become the most sought after big game animal in California. Their great reproductive capacity coupled with the ruggedness of their preferred habitat has allowed the California State Fish and Game Department to set liberal seasons and bag limits. The freedom to work within the states liberal framework has prompted some private land managers to look at controlled …

Feral Burros And Wildlife, Richard A. Weaver

Vertebrate Pest Conference Proceedings: 6th (1974)

Feral burro have caused devastating damage to the vegetation and soil which has resulted in a deterioration of the entire biota. Wildlife numbers have declined where there is competition with burro for food, water or space.

The Department of Fish and Game made a burro survey in conjunction with bighorn investigations. There are an estimated 3,400 free-roaming wild burro in California. They are found in 7 of the 14 bighorn study areas and have caused problems in each of these areas.

Modelling For Research On Chemical Control Of Mammals In New Zealand, C.L. Batcheler, J. Bell

Vertebrate Pest Conference Proceedings: 6th (1974)

Development of predictive formulae or qualitative statements about the probable outcome of control campaigns entails knowledge of bait quality and distribution, behavior, vagaries of weather at the time of the control campaign, and other factors which govern the probability that the target animals will accept bait.

This paper collates experience in recognizing, estimating and using some of these variables for predicting the outcome of large-scale poisoning, and discusses possible approaches to the solution of some hard-core problems.

Rabbit Behavior Research In Australia And Its Relevance In Control Operations, B.V. Fennessy

Vertebrate Pest Conference Proceedings: 6th (1974)

Research in Australia on the behavior of wild rabbits has provided a basis for improvements in the tactics and strategy of control.

As the warren is a central focus for growth and survival of a population, a program for effective control or eradication should a i m at making the warren unavailable to rabbits.

Enclosure studies of behavior suggested that poisoning would be much more effective when carried out in the non-breeding season. This has been confirmed in field trials.

The behavioral importance of the odor-producing inguinal , submandibular, and anal glands is emphasized. It is suggested that further studies …

The Role Of W.H.O. In The Study And Control Of Rodent-Borne Disease, N.G. Gratz

Vertebrate Pest Conference Proceedings: 6th (1974)

While little information is available on the distribution and incidence of most of the diseases with rodent reservoirs, many of them are known to be widespread and may have considerable public health importance in some of the foci in which they are found. The World Health Organization is carrying out investigations on the epidemiology of several diseases with rodent reservoirs and on the biology and ecology of the rodent reservoir species themselves. These investigations are being carried out both at WHO research u n i t s and with collaborating laboratories. Based on the ecological information the organization is attempting …

The Detection Of Exotic Vertebrate Pests In California, Michael O. Keffer

Vertebrate Pest Conference Proceedings: 6th (1974)

Numerous exotic vertebrates are imported into California each year for use in scientific research, zoological gardens, the commercial pet trade, and private collections. Certain of these imported species are known within their native range to depredate agricultural commodities, compete with other species of wildlife , and facilitate the spread of. diseases detrimental to humans or other animals.

The California Department of Food and Agriculture, in cooperation with other governmental agencies and conservation-oriented societies, is active in the exclusion, detection, and eradication of these detrimental species. Exclusion procedures include inspections of air cargo, truck, and postal terminals in addition to private …

The Role Of F.A.O. In Vertebrate Pest Problems, H.R. Shuyler

Vertebrate Pest Conference Proceedings: 6th (1974)

Since 1947, when FAO began its involvement in vertebrate pest problems, its role has gradually expanded. Through short-term Consultants, Experts, Regional and Headquarters Officers, it advises Member Countries about vertebrate pest control needs and opportunities, fulfills requests for assistance suggesting needed modifications, and guides and reports on assistance rendered. Assistance may involve one or more international specialists for a few weeks up to national and regional projects of several years' duration. In cooperation with WHO it sponsors meetings of specialists, develops rodenticide specifications for international commerce, and has published rodent bibliographies covering 1950 to 1969.

Seasonal Changes In Water Quality And Primary Productivity In Doe Valley Lake, Edmond J. Bacon, Stuart E. Neff

KWRRI Research Reports

Primary productivity and water quality were studied in Doe Valley Lake, a 147-hectare impoundment on Doe Run, a spring-fed stream in Meade County, Kentucky, from 13 June 1969 to 31 July 1972. Doe Valley Lake is monomictic during most winter seasons, but it is dimictic during more severe winters because of its morphometry and location on the borderline climatic region for dimictic lakes (37° N latitude). Oxygen depletion in the hypolimnion is severe, and anaerobic conditions usually prevail by late June. A hypolimnetic areal deficit of 0.038 mg/cm²/day was calculated. Supersaturation of oxygen in the epilimnion was common, …

Pheasant Management Recommendations, William L. Baxter

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Information on the life history and ecology of the ring-necked pheasant was collected on two, nine-square-mile study areas in Clay County, Nebraska, from 1954 through 1964. The study was designed to provide basic data that would allow scientifically based management decisions to be made for the maintenance and enhancement of ring-neck populations.

Findings indicate certain steps should be taken to improve pheasant populations on state-owned or controlled lands, as well as recommendations to improve habitat for pheasant populations on land not controlled by the Game Commission, These secondary proposals have statewide ramifications and offer potential for significantly improving pheasant populations …

Effects Of Mosquito Control Chemicals On Aquatic Fauna, J. L. Lancaster Jr., M. V. Meisch

Arkansas Water Resources Center Technical Reports

No mosquito abatement districts have ever been organized in Arkansas. Mosquito control efforts have been largely adulticiding operations by either aerial application or ground thermal fogging machines. Practically no chemical applications have been directed at the larval stage in residual water in ditches and depressions from which adult populations arise. Some larviciding with ethyl parathion has been done in ricefields. Although the treatment is very effective in mosquito reduction, voluntary treatment has not been completely successful. Because relatively little insecticide has been used as a larvicide in Arkansas, it was possible to evaluate the effect of recommended larvicides on non-target …

Environmental Evaluation Report On The Big Mulberry Creek Basin In Franklin, Madison, Newton, Johnson And Crawford Counties, Arkansas, Edward E. Dale Jr.

Arkansas Water Resources Center Technical Reports

The environmental evaluation report which follows is based on information supplied by the Corps of Engineers, Little Rock District, available literature, field observations made during the summer of 1972, and results of research now in progress on natural features of the Big Mulberry Basin. Since most major dams, levees, and flood retarding structures now in existence in the Ozarks have been constructed since about 1940, opportunities to make long term studies of their effects have been limited. Also, the natural vegetation, fauna, and archeology of the Big Mulberry Basin have not been extensively investigated, but available sources provide enough information …

Fisheries Report No 15 - The Western Rock Lobster Fishery 1972 - 1973, G. R. Morgan, E H. Barker

Fisheries Research Reports

The fishery for the western rock lobster* is one of the most important single fisheries in Australia and an important export earner for the State. The fishery is governed by a complex set of regulations which have been reviewed by Bowen (1971) and which are designed to limit the total effort to acceptable levels and to enforce a legal minimum size. It is thus important to constantly monitor the state of the fishery both to ensure that the effort is remaining within the accepted limits and that the regulations are adequately performing their function of maintaining reasonably stable catches. Inherent …
