Effects Of Free-Ranging Cats On Wildlife: A Progress Report, J.S. Coleman, S.A. Temple
Effects Of Free-Ranging Cats On Wildlife: A Progress Report, J.S. Coleman, S.A. Temple
Fourth Eastern Wildlife Damage Control Conference (1989)
We have embarked upon a three-year study to determine the density and distribution of free-ranging cats (Felis catus) and their effects on prey populations in rural Wisconsin. The effects of predation by free-ranging cats on wildlife populations are potentially great and have not been adequately accounted for in wildlife management programs. In rural Illinois there was an average of 5.6 free-ranging cats per farm (Warner 1985). If densities elsewhere are similar, then a state such as Wisconsin, with over 200,000 active and retired farms, could have over 1 million free-ranging cats on farms. In other studies (Bradt 1949, …
Farmer Attitudes Toward Wild Turkeys In Southwestern Wisconsin, Scott R. Craven
Farmer Attitudes Toward Wild Turkeys In Southwestern Wisconsin, Scott R. Craven
Fourth Eastern Wildlife Damage Control Conference (1989)
The reintroduction of the Wild Turkey (Meleagris gallopavo) represents one of the great success stories for Wisconsin wildlife management. Human settlement, habitat loss, and perhaps disease, combined to eliminate once-common turkeys from Wisconsin by 1900. Periodic attempts to restore a viable turkey population were unsuccessful with the exception of a small flock at Meadow Valley-Necedah in central Wisconsin. However in 197'6, the Wisconsin Department of Natural Resources (WDNR) began a new, well conceived cooperative project with the Missouri Department of Conservation. Under the agreement, Missouri received 3 wild Wisconsin ruffed grouse (Bonasa umbellus) in exchange for …

Economic Impact And Control Of Wading Birds At Arkansas Minnow Ponds, Michael D. Hoy, Jeffrey W. Jones, Albert E. Bivings
Economic Impact And Control Of Wading Birds At Arkansas Minnow Ponds, Michael D. Hoy, Jeffrey W. Jones, Albert E. Bivings
Fourth Eastern Wildlife Damage Control Conference (1989)
Esophageal/stomach contents of 172 little blue herons (Egretta caerulea), great egrets (Casmerodius albus), snowy egrets (Egretta thula), and great blue herons (Ardea herodias) were analyzed to estimate their consumption of golden shiners. Mean and maximum number of golden shiners consumed/bird, as well as the mean total length of golden shiners consumed by each wading bird species was determined. Loss estimates varied by wading bird species and ranged from $0.10 - $1.12/bird/feeding. Loss estimates reflect the severity of problems with wading birds on minnow ponds and the need to reduce losses by use …
Epa Update On Vertebrate Pesticides, William W. Jacobs
Epa Update On Vertebrate Pesticides, William W. Jacobs
Fourth Eastern Wildlife Damage Control Conference (1989)
The U.S. Environmental Protection Agency regulates pesticides under the authority of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). Vertebrate pesticides are subsumed under the heading "rodenticides” and, under FIFRA, are regulated similarly to other pesticides. Since its enactment in 1947, FIFRA has been amended many times (e.g., in 1959, 1964, 1972, 1978, and 1988.) These amendments generally have required progressively greater documentation of the effects of pesticides upon man, other nontarget species, and the environment prior to the issuance of full federal registration under Section 3 of FIFRA.
Survey Of Mississippi Catfish Farmers On Means, Effort, And Costs To Repel Fish-Eating Birds From Ponds, A.R. Stickley, K.J. Andrews
Survey Of Mississippi Catfish Farmers On Means, Effort, And Costs To Repel Fish-Eating Birds From Ponds, A.R. Stickley, K.J. Andrews
Fourth Eastern Wildlife Damage Control Conference (1989)
Eighty-seven percent of 281 Mississippi catfish farmers felt that fish-eating birds were enough of a problem to warrant harassment. Fanners estimated that they spent an average of 2.6 man-hours per day harassing birds at an average annual cost of $7400. Sixty percent of the farmers who harassed birds did so by driving around the ponds and firing at birds to repel them. Propane exploders and pyrotechnics were also used. Pyrotechnics were judged the most effective repellent technique. The cost of bird harassment according to these farmers is $2.1 million. The value of fish loss to cormorants alone is roughly estimated …
Farmland Habitat Use By Wild Turkeys In Wisconsin, R.G. Wright, R.N. Paisley, J.F. Kubisiak
Farmland Habitat Use By Wild Turkeys In Wisconsin, R.G. Wright, R.N. Paisley, J.F. Kubisiak
Fourth Eastern Wildlife Damage Control Conference (1989)
Habitat use and food habits of wild turkeys (Meleagris pallopavo) were studied during summer 1988-89 in southwestern Wisconsin in order to address growing concerns that turkeys cause considerable crop damage. Intensive telemetric monitoring in 1988 suggested that turkeys used crop fields (corn-alfalfa-oats) at a low rate compared to forest types. Brooded hens used forest habitats less and field habitats more than broodless hens and gobblers. Brooded hens appeared to use forest and crop field habitats less and non-crop fields (pasture and idle) more than expected. Broodless hens and gobblers appeared to use forest types and non-crop fields more …

The Usda-Aphis-Adc Program In The United States, Bobby R. Acord
Fourth Eastern Wildlife Damage Control Conference (1989)
The ADC program was transferred to the U.S. Department of Agriculture, Animal and Plant Health Inspection Service in 1986. Shortly after the transfer, the Secretary of Agriculture established the National Animal Damage Control Advisory Committee (NADCAC). Current and future issues facing ADC are discussed in the context of NADCAC recommendations.
A Review Of The Status Of Bird Management Products And Devices In The United States, Charles W. Areson
A Review Of The Status Of Bird Management Products And Devices In The United States, Charles W. Areson
Fourth Eastern Wildlife Damage Control Conference (1989)
Commercial urban /industrial structural pest bird control is approaching a time of crisis. Several long-standing toxicants that have been used as a major part of pest bird control programs are either suspended, at risk of suspension, or have had their production terminated by the manufacturer. "Environmental groups" are up in arms about the use and misuse of pesticides. Lawsuits have been filed to stop the use of some products, and political pressure has brought about reviews of some pesticide products on both the state and federal levels. EPA has seemed to have a "get tough" policy in its reregistration guidelines, …
Gis: A Tool For Analyzing And Managing Deer Damage To Crops, Glenn R. Dudderar, Jonathan B. Haufler, Scott R. Winterstein, Petrus Gunarso
Gis: A Tool For Analyzing And Managing Deer Damage To Crops, Glenn R. Dudderar, Jonathan B. Haufler, Scott R. Winterstein, Petrus Gunarso
Fourth Eastern Wildlife Damage Control Conference (1989)
A common problem of biologists and agriculturists trying to control white-tailed deer (Odocoileus virginianus) damage to crops is understanding the causes and alternative solutions to the damage over multi-county or state-wide areas. Deer damage a variety of crops in different ways at different times of the year. Crops damaged, types of damage, and damage severity are influenced by deer densities, distributions, movements and harvest, as well as field size and interspersion with surrounding land cover types and uses. The complexity of the interaction of these factors requires improved analysis if the most appropriate control methods are to be …
The Effectiveness Of Orco Mole Bait In Controlling Mole Damage, Dale K. Elshoff, Glenn R. Dudderar
The Effectiveness Of Orco Mole Bait In Controlling Mole Damage, Dale K. Elshoff, Glenn R. Dudderar
Fourth Eastern Wildlife Damage Control Conference (1989)
The tunneling damage caused by eastern moles (Scalopus aquaticus) and star-nosed moles (Condvlura cristata) is well known to professionals in lawn care, golf course maintenance, and turf grass production, as well as many private landowners. Present damage control methods, including trapping, gas and smoke fumigants, and insecticide applications have a wide variety of limitations and prove impractical in some situations. An easily applied mole damage control method is needed that professional and nonprofessional applicators can use in a variety of environmental and physical conditions. This study tested the effectiveness of Oreo Mole Bait, a chlorophacinone pellet …

Population Dynamics And Management Of Deer In Wisconsin, Keith R. Mccaffery
Population Dynamics And Management Of Deer In Wisconsin, Keith R. Mccaffery
Fourth Eastern Wildlife Damage Control Conference (1989)
Management of deer in Wisconsin is affected by a combination of biological and environmental factors. In the Northern Forest, winter severity dramatically affects annual survival and recruitment. However, deer density goals here are above "I" carrying capacity. Thus, minor errors in harvest management are in part compensated by herd responses. Deer in the farmland areas of the state are maintained at goals that for the most part are below "I" carrying capacity. Errors in harvest management are magnified in farmland because herd responses are not compensatory. Therefore, the harvest quotas for antlerless deer must be more precise in our farmland …
Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa, James E. Forbes
Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa, James E. Forbes
Fourth Eastern Wildlife Damage Control Conference (1989)
The New York State Cooperative Coyote Damage Control Program was established in late 1986 through a cooperative agreement between the New York State Department of Agriculture and Markets (NYSDAM) and USDA/ APHIS/ ADC in response to escalating complaints of coyote (Canis latrans) depredations on sheep from 1980-85. Ten counties with histories of and/or potential for coyote/livestock conflicts were identified and targeted for publicity and primary program emphasis. Program staff received 58 reports of coyote depredations on 182 sheep from 32 producers in the ten target counties and seven outlying counties from May 1987 through May 1989/ and verified 46 complaints …
Depredation Permits For Migratory Birds, Larry L. Hood
Depredation Permits For Migratory Birds, Larry L. Hood
Fourth Eastern Wildlife Damage Control Conference (1989)
All of the native species of birds in the United States are protected by either federal or state laws. Under the Migratory Bird Treaty Act, the federal government has formulated regulations that assist in controlling protected species that cause economic damage or health hazards. These regulations are in Subpoint D of Part 21, Title 50 Code of Federal Regulations, and may take the form of standing depredation orders or permits issued to kill those species that cause problems.
An Investigation Of Animal Damage Associated With Maple Syrup Production, J. Allan May, Dennis Slate
An Investigation Of Animal Damage Associated With Maple Syrup Production, J. Allan May, Dennis Slate
Fourth Eastern Wildlife Damage Control Conference (1989)
An increase in the use of plastic tubing systems to collect sap from sugar maples (Acer saccharum) has allowed syrup producers to boost production in recent years, but not without cost. Rodents gnawing on tubing, spouts, and fittings may cause damage in excess of $300,000 annually in Vermont, the largest maple producing state. Red squirrels (Tamiasciurus hudsonicus), gray squirrels (Sciurus carolinensis), and chipmunks (Tamias striatus) appear to be responsible for the majority of damage. Other species including flying squirrels (Glaucomvs sabrinus) , white-footed mice (Peromvscus leucopus), porcupines ( …
A Revolution In Bird Control, Michael Amir
A Revolution In Bird Control, Michael Amir
Fourth Eastern Wildlife Damage Control Conference (1989)
Bird control methods currently in use at airports are often effective for only a short period of time and are only designed to frighten birds on the ground. Air Birdstrike Prevention Inc. (ABP Inc.) has designed and developed a new approach. Remote controlled aircraft, equipped with airborne pyrotechnic devices,(U.S. and Canada Patent Pending), that flies after the birds, redirecting them out of the airport and reducing the bird population in the airport vicinity without harming the birds.
Preliminary Evaluation Of A Granular Trimethacarb Formulation For Deterring Grazing By American Coots, Michael L. Avery, Curtis Nelms, J. Russell Mason
Preliminary Evaluation Of A Granular Trimethacarb Formulation For Deterring Grazing By American Coots, Michael L. Avery, Curtis Nelms, J. Russell Mason
Fourth Eastern Wildlife Damage Control Conference (1989)
In a 0.2 ha flight pen, groups of 4 American coots were tested to determine if their grazing activity could be affected by application of a registered granular-trimethacarb insecticide. In the 3 days following treatment (3 kg/ha, a.i.), grazing activity in the treated portions of the 200 m2 experimental plots was reduced an average of 47X. Overall use of the treated areas followed a similar pattern but was less consistent among groups. The addition of methylpyrazine, a strong odorant, produced a strong initial suppression of grazing activity in the treated halves of the plots. However, subsequent rain and a change …

Fourth Eastern Wildlife Damage Control Conference (1989)
In addressing the role of private enterprise in wildlife damage control, I will not be bringing the final word or a comprehensively exhaustive report. Rather, I will be presenting some perspectives as the representative of a firm with extensive involvement with wildlife damage control as a business. My comments will be divided into why, what, how, and the future.
Persistence Of Tartrazine In Marking Sheep Wool, Richard J. Burns, Peter J. Savarie
Persistence Of Tartrazine In Marking Sheep Wool, Richard J. Burns, Peter J. Savarie
Fourth Eastern Wildlife Damage Control Conference (1989)
Tartrazine was examined as a possible replacement marker for rhodamine B in the Livestock Protection Collar. Test solutions were formulated in six combinations; tartrazine at 0.5% and 1.07. concentrations, with and without compound 1080, and with and without nigrosin black. Each solution was examined for persistence of color in the laboratory and when applied to the wool of dried sheep hide. Hide pieces were allowed to weather naturally or were sprinkled to simulate rain. Tartrazine alone was also tested at concentrations of 0.5% and 1.0% on the necks of sheep. Over a 3—month period, no fading was noted in the …

Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn
Fourth Eastern Wildlife Damage Control Conference (1989)
During the winters of 1987-88 and 1988-89 a study was conducted to evaluate the potential of DRC-1339 baiting for controlling roosting European Starlings (Sturnus vulgarus) at Tennessee Eastman Company's chemical manufacturing plant in Kingsport, Tennessee. In 1987-88 Starlicide Complete® (1 %, DRC-1339 treated poultry pellets diluted 1:9 with untreated poultry pellets) was used in pre-roosting congregating areas adjacent to the roost. In 1988-89 Starlicide Complete® and DRC-1339 treated bread were used in bait containers placed in the roosting structure. Although 90 lbs of Starlicide Complete® was consumed during 1987-88, bait consumption was sporadic and no appreciable change in …
Wildlife Damage To Crops: Perceptions Of Agricultural And Wildlife Professionals In 1957 And 1987, Michael R. Conover, Daniel J. Decker
Wildlife Damage To Crops: Perceptions Of Agricultural And Wildlife Professionals In 1957 And 1987, Michael R. Conover, Daniel J. Decker
Fourth Eastern Wildlife Damage Control Conference (1989)
We surveyed state wildlife agencies, state agricultural departments, Wildlife Extension Specialists, U.S.D.A. Animal Damage Control agents, and state Farm Bureau officials to develop a national perspective of wildlife damage to agricultural crops in the U.S. A broad concensus existed that wildlife damage was a major problem, although groups often differed in their perceptions of the seriousness of specific problems. The complexity of the wildlife damage problem was apparent in that 27 different wildlife species were cited as causing the greatest problem to a state's farmers. Nevertheless, 38-80% of the respondents from every group surveyed stated that deer were their worst …
Beaver And Beaver Dam Removal In Wisconsin Trout Streams, Larry Dickerson
Beaver And Beaver Dam Removal In Wisconsin Trout Streams, Larry Dickerson
Fourth Eastern Wildlife Damage Control Conference (1989)
Beaver (Castor canadensis) dam building activities create many long-term affects on stream ecosystems. Beaver dams may negatively influence trout fisheries by creating physical barriers to spawning areas, increasing sediment retention, and increasing water temperatures. The U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) Animal Damage Control (ADC) program in Wisconsin, entered into cooperative agreements with the Wisconsin Department of Natural Resources (WDNR) and the U.S. Forest Service (USFS) on the Nicolet National Forest from June through September, 1988, to remove beaver and beaver dams from priority classed trout streams. Four hundred and eight beaver …

Laughing Gulls At Jfk Airport: Safety Hazard Or Wildlife Resource?, R.A. Dolbeer, M. Chevalier, P.P. Woronecki, E.B. Butler
Fourth Eastern Wildlife Damage Control Conference (1989)
John F. Kennedy International Airport is adjacent to Jamaica Bay Wildlife Refuge administered by the National Park Service. In 1979, 15 pairs of laughing gulls (Larus atricilla) nested on the refuge, the first recolonization of Long Island by this species since the gulls' disappearance from New York around 1900. The colony, with nests as close as 0.4 km to 1 runway, has subsequently increased to about 3,000 pairs. From 1970 to 1978, only 1 laughing gull strike by an aircraft was recorded at JFK. From 1979 through August 1989, 800 strikes were recorded, including 179 in 1989, in …
A Fencing Technique To Reduce Raccoon Feeding Damage To Sugarcane Research Plots, Hugh P. Fanguy, Dwight Leblanc
A Fencing Technique To Reduce Raccoon Feeding Damage To Sugarcane Research Plots, Hugh P. Fanguy, Dwight Leblanc
Fourth Eastern Wildlife Damage Control Conference (1989)
Damage caused by the feeding of raccoons (Procvon lotor) on stalks of sugarcane (Saccharum sp.) has occurred for several years on the 200-acre U.S. Department of Agriculture, Agricultural Research Service (USDA-ARS) research farm located near Houma, Terrebonne Parish, Louisiana. Damage begins when sugarcane mature internodes begin to from in late June and early July, and continues until the completion of harvest in late December. Raccoons appear to prefer varieties having low fiber and/or high sugar content and can severely damage these varieties (personal observation). Depredation by these animals frequently result in loss of data as preferred varieties …

Wildlife Damage In Electric Substations In New York, Jody W. Enck
Wildlife Damage In Electric Substations In New York, Jody W. Enck
Fourth Eastern Wildlife Damage Control Conference (1989)
Wildlife managers have long been concerned with the damage wildlife can cause, especially to agricultural crops. However, one area which has received little research is the damage caused by wildlife to electric substations. Such research is needed because damage to electric substations increases operating costs of utilities and reduces reliability of service to customers. Six member utilities of the Empire State Electric Energy Research Corporation (ESEERCO) were surveyed to identify classes of substations experiencing animal-caused faults (i.e., short circuits), and to determine the impacts of those faults. Records of more than 200 animal-caused faults occurring from 1970-88 were examined. The …
Evaluation Of A Canada Goose Call-Activated Switch For Crop Damage Abatement, James W. Heinrich, Scott R. Craven
Evaluation Of A Canada Goose Call-Activated Switch For Crop Damage Abatement, James W. Heinrich, Scott R. Craven
Fourth Eastern Wildlife Damage Control Conference (1989)
Damage and nuisance problems caused by Canada geese (Branta canadensis) are difficult to control with current abatement technology. We tested the efficacy of a goose call-activated switch as a modification for propane exploders (gas cannons), using recorded Canada goose calls and live goose trials. We recorded a 30 m range for the switch and found that it was activated by a range of non-target sounds. The development of this device and the technology involved are discussed. The call-activated switch is not a useful tool in reducing Canada goose damage in crop fields. Canada geese frequently feed on agricultural …
Impact Of Wolves On White-Tailed Deer In North-Central Minnesota, Todd K. Fuller
Impact Of Wolves On White-Tailed Deer In North-Central Minnesota, Todd K. Fuller
Fourth Eastern Wildlife Damage Control Conference (1989)
Field studies conducted in north-central Minnesota during 1980-1986 suggest that wolves (Canis lupus) killed about 6% of the white-tailed deer (Odocoileus virginianus) population (including fawns). Given certain assumptions, simple equations can be used to estimate sustainable numbers of deer, wolves, and hunter harvest in an area.
Zinc Phosphide Rodenticide Reduces Cotton Rat Populations In Florida Sugarcane, Nicholas R. Holler, David G. Decker
Zinc Phosphide Rodenticide Reduces Cotton Rat Populations In Florida Sugarcane, Nicholas R. Holler, David G. Decker
Fourth Eastern Wildlife Damage Control Conference (1989)
Rodents cause extensive damage to sugarcane (Saccharum spp. hybrids) in southern Florida (Samol 1972). Losses have been estimated as high as $235/ha (Lefebvre et al. 1978). Cotton rats (Sigmodon hispidus) and roof rats (Rattus rattus) are responsible for most of the damage (Holler et al. 1981). In-field treatment is required for effective reduction of rat populations because of the distribution and restricted movement patterns of rats within fields (Lefebvre et al. 1985a). Zinc phosphide (2%) baits are the only rodenticide baits registered for in-field use in Florida sugarcane. A preliminary test of in-crop aerial application …
