Black Bear Damage In Virginia, Michael R. Vaughan, Patrick F. Scanlon, Sue Evelyn P. Mersmann, Dennis D. Martin
Wildlife Damage Management Conference
We examined records of black bear damage in Virginia on Shenandoah National Park, (SNP) (1979-1988) and non-Park lands (1973-1988). Mean annual damage was $5,470 on non-Park lands and $1,217 on the Park. Corn and beehives accounted for 79 percent and personal property for 72 percent of the economic loss on non-Park and Park lands respectively. Young males were responsible for most damage on non-Park lands while adults of both sexes caused most damage on SNP. Over 70 percent of bear damage incidents in the state occurred either on the Park or on land immediately adjacent to the Park. Moving bears …
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
Wildlife Damage Management Conference
Habitat use and food habits of wild turkeys (Meleagris gallopavo) 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 …
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
Wildlife Damage Management Conference
In a 0.2 ha flight pen, group 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 47%. 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 …
Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn
Controlling Roosting Starlings In Industrial Facilities By Baiting, Bernice U. Constantin, James F. Glahn
Wildlife Damage Management Conference
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 CompleteR (1% DRC-1339 treated poultry pellets diluted 1:9 with untreated poultry pellets) was used in preroosting congregating areas adjacent to the roost. In 1988-89 Starlicide CompleteR and DRC-1339 treated bread were used in bait containers placed in the roosting structure. Although 90 lbs of Starlicide CompleteR was consumed during 1987-88, bait consumption was sporadic and no appreciable change in the …
Wildlife Disease Concerns In Animal Damage Control, Sarah Shapiro Hurley
Wildlife Disease Concerns In Animal Damage Control, Sarah Shapiro Hurley
Wildlife Damage Management Conference
There are many facets to the topic of wildlife disease concerns in animal damage control, but the area that I have chosen to discuss is that of zoonotic disease - diseases which are transmissible in nature between humans and other animals. The list of zoonoses is extensive and in the time available only a few can be reviewed.
Florida's Nuisance Alligator Control Program, Michael L. Jennings, Allan R. Woodward, Dennis N. David
Florida's Nuisance Alligator Control Program, Michael L. Jennings, Allan R. Woodward, Dennis N. David
Wildlife Damage Management Conference
The recovery of alligators from centuries of exploitation, coupled with a burgeoning human population in Florida has resulted in an increasing number of problem animals and alligator attacks. In response to this problem, the Florida Game and Fresh Water Fish Commission implemented a nuisance alligator control program in 1978. A mean of 2513 nuisance alligators per year was harvested during the period 1978 to 1988. The number of alligator complaints, nuisance alligators harvested, and alligator attacks increased significantly over the period (P=0.0003, P=0.0001, and P=0.04). The value of alligator meat remained stable at about $5.00/pound over the same period, while …
Fertility Control As A Tool For Regulation Of Wildlife Populations, U. S. Seal
Fertility Control As A Tool For Regulation Of Wildlife Populations, U. S. Seal
Wildlife Damage Management Conference
Biological control of reproduction and fertility is a normal part of the life history of all organisms. Control mechanisms allow timing of reproduction with respect to age, time of day, season, and other periodic environmental events. Further modulation can occur with variations in temperature, rainfall, nutrition, and health status. Interactions with other members of the species, ranging from pherohormonal stimulation of estrus to social delay of puberty and breeding to infanticide, provide further constraints upon fertility and recruitment. All of these processes ultimately act through molecular neuroendocrine mechanisms that are under genetic control and are subject to natural selection and …
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
Wildlife Damage Management Conference
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 1.0% 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 …
Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa Jr., James E. Forbes
Coyote Depredation Control In New York - An Integrated Approach, Thomas N. Tomsa Jr., James E. Forbes
Wildlife Damage Management Conference
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 …
Extent And Nature Of Deer Damage To Commercial Nurseries In New York, Roger W. Sayre, Daniel J. Decker
Extent And Nature Of Deer Damage To Commercial Nurseries In New York, Roger W. Sayre, Daniel J. Decker
Wildlife Damage Management Conference
We surveyed nursery producers in New York to determine the extent, nature and economic impact of deer damage to their operations, and to assess their attitudes towards deer. Seventy-three percent of the producers experienced deer damage to their crops in 1988. Average costs for replacement were nearly $6,000 per grower for those reporting damage estimates (and over $8,000 if 1 extreme value was included). Statewide damage estimates ranged from $500,000 to $1.2 million (depending on assumptions). Forty-six percent used damage control, which cost an average of about $2,000 per grower. More than 80% of the producers were classified as "nonaccepting" …

Demonstration Electric Fences To Control Black Bear Damage To Apiaries In New York State, Janet L. Sillings, Thomas N. Tomsa Jr., James E. Forbes
Wildlife Damage Management Conference
The New York State black bear (Ursus americanus) population, approximately 4,000 animals (Clarke 1977), causes damage to apiaries in the catskill, Adirondack, and Southern Tier regions of the state. During 1987, 1988, and 1989, USDA Animal Damage Control (ADC) administered a program in New York to control bear damage to apiaries. Control activities were carried out pursuant to a Cooperative Agreement between ADC and the New York State Department of Agriculture and Markets, and were supported by matching Federal-State contributions. Program objectives were beekeeper education aimed at preventing bear damage and for the construction of demonstration temporary electric …
