Avoiding Controversies That Impede Wildlife Damage Control, B.W. O'Gara
Avoiding Controversies That Impede Wildlife Damage Control, B.W. O'Gara
Third Eastern Wildlife Damage Control Conference (1987)
Controversies regarding wildlife damage control often result from incorrect perceptions by the general public or conservation groups. Such controversies can usually be settled to most people's satisfaction by indisputable data. In the past, however, data were often lacking. The ban, by Executive order in 1972, of chemical toxicants for predator control on federal lands and by federal agencies is a good case in point. Indisputable data were not available concerning the level of predation. The only data were derived from questionnaires filled out by livestock producers; Government officials and the public simply would not accept such data as unbiased.

The Economic Impact Of Wildlife Damage On Hudson Valley Orchards, M. Phillips, C.G. Forshey, G.B. White, M.E. Richmond
The Economic Impact Of Wildlife Damage On Hudson Valley Orchards, M. Phillips, C.G. Forshey, G.B. White, M.E. Richmond
Third Eastern Wildlife Damage Control Conference (1987)
The impact of wildlife damage on the profitability of apple farming in New York's Hudson Valley was determined by vise of a Standard Net Present Value (NPV) analysis as a means to measure long-term impact. Data were gathered through questionnaire and interview of a stratified random sample of 39 growers that represented 17% of the regional growers. Data concerning species causing damage, extent of wildlife damage and types of controls used were combined with current and long-range costs including revenue lost through damage and control costs. Limitations of the analysis are discussed along with results that indicate an annual equivalent …
Deer Damage Control Preferences And Use Decisions Of New York Orchardists, K.G. Purdy, W.F. Siemer, G.A. Pomerantz, T.L. Brown
Deer Damage Control Preferences And Use Decisions Of New York Orchardists, K.G. Purdy, W.F. Siemer, G.A. Pomerantz, T.L. Brown
Third Eastern Wildlife Damage Control Conference (1987)
Previous studies in New York, the nation's second leading state in apple production, have contributed much to deer management decisions that give consideration to orchardists' concerns about crop damage. Little information, however, has been reported about orchardists' reasons for adopting or not adopting particular types of deer damage controls or their preference for various forms of possible damage control assistance. Two complementary studies, conducted in early 1987 by the Human Dimensions Research Unit, Department of Natural Resources, Cornell University, have addressed these information needs. A mail survey of orchardists in an important fruit-producing region of southeastern New York indicated that …
Rodenticide Use In Agricultural Crops, Terrell P. Salmon
Rodenticide Use In Agricultural Crops, Terrell P. Salmon
Third Eastern Wildlife Damage Control Conference (1987)
The in-crop use of pesticides is allowed only after establishment of a crop tolerance with supporting residue data for the crop. Residue data from different regions and pesticide application methods (hand treatment, aerial broadcast, etc.) are required. Most rodenticide uses have been considered as non-crop since they are generally applied in and around rodent burrows and runways. Because of this, rodenticides do not generally have tolerances or residue information for crop use. Recent inquiries by the Environmental Protection Agency (EPA), a review of current rodenticide labels, and new pesticide laws, suggest the need for reevaluating the question of in-crop use …
The Future Of Wildlife Damage Control In An Urban Environment, Gary J. San Julian
The Future Of Wildlife Damage Control In An Urban Environment, Gary J. San Julian
Third Eastern Wildlife Damage Control Conference (1987)
As the trend towards urbanization escalates, the United States is rapidly becoming a nation of non-farmers and suburban residents. Consequently, the conflicts between residents and wildlife species are increasing, while the interest in urban wildlife and backyard habitat is growing. These ' trends, coupled with changes in pesticide regulations, a shortage of trained professionals and relic legislation, create a complex and paradoxical situation for residents and professionals in the area of urban wildlife management. The future of wildlife in the urban environment will depend on our ability to convince and educate wildlife managers, citizens and legislators about the need for …
Nonpredatory Mammal Damage Research Needs, John L. Seubert
Nonpredatory Mammal Damage Research Needs, John L. Seubert
Third Eastern Wildlife Damage Control Conference (1987)
Nonpredatory mammal damage probably exceeds one-half billion dollars each year in the U.S., in spite of many techniques and programs for controlling such losses. Improved and new control methods are obviously needed. The task of ADC researchers has become increasingly demanding and complex, however. They must not only obtain information to satisfy recurring Environmental Protection Agency (EPA) data call-ins required to maintain and improve existing State and Federal rodenticide registrations, but must develop and register new damage control techniques and strategies. New methods must be highly efficacious, safe, cost effective, and present the lowest possible hazard to non-target species and …
Research Needs In Wildlife Damage Control, Dennis Slate
Research Needs In Wildlife Damage Control, Dennis Slate
Third Eastern Wildlife Damage Control Conference (1987)
This presentation provides a brief overview of wildlife damage-related research needs as they are perceived by Animal and Plant Health Inspection Service (APHIS), Animal Damage Control (ADC) State Directors in the Eastern ADC Region. There are 23 State Directors in the Eastern ADC Region who are responsible for managing operational and technical assistance animal damage programs in 31 states. Because of their collective experience with a variety of species and control techniques under various environmental circumstances, their input and insight should be valuable in helping those in the research community more clearly define wildlife damage-related research needs. State Directors responded …
Decontamination Of A Histoplasma Capsulatum-Infested Blackbird Roost: Use Of A Sprinkler System To Apply Formalin, A.R. Stickley Jr., J.R. Pruitt, C.E. Hume, T. Pass Ii, C.H. Gayle
Decontamination Of A Histoplasma Capsulatum-Infested Blackbird Roost: Use Of A Sprinkler System To Apply Formalin, A.R. Stickley Jr., J.R. Pruitt, C.E. Hume, T. Pass Ii, C.H. Gayle
Third Eastern Wildlife Damage Control Conference (1987)
When disturbed, blackbird/ starling roost sites can be sources of locally severe outbreaks of histoplasmosis; therefore decontamination with formalin is sometimes prudent. We describe the use of a $5000 sprinkler system for spraying formalin on a Histoplasma capsulatum-infested roost site. This system precludes direct worker involvement in the application of this hazardous chemical to the area. Analysis of soil samples collected and cultured both before and after formalin treatment confirmed the eradication of H. capsulatum from the 1.3 ha site. Cost was approximately $17,000 with sprinkler system provided at no charge.
Status Of Mesurol® As A Bird Repellent For Cherries And Other Fruit Crops, Mark E. Tobin, Richard A. Dolbeer
Status Of Mesurol® As A Bird Repellent For Cherries And Other Fruit Crops, Mark E. Tobin, Richard A. Dolbeer
Third Eastern Wildlife Damage Control Conference (1987)
A single application of Mesurol at 1.5 Ib (Al) /ac to ripening cherries reduced bird damage in a field test in the mid-Hudson Valley of New York, 1986. Treated trees averaged 8.9% damage compared to 17.5% damage for untreated trees. An average of 7.4 birds flew into treated blocks per 15-min count versus an average of 19.8 birds that flew into control blocks. These results support the various evaluations over the past 15 years of Mesurol as a bird repellent for fruit crops. The consensus of these tests is that Mesurol often provides an effective nonlethal means of reducing conflicts …
Bait Stations For Controlling Voles In Apple Orchards, Mark E. Tobin, Milo E. Richmond
Bait Stations For Controlling Voles In Apple Orchards, Mark E. Tobin, Milo E. Richmond
Third Eastern Wildlife Damage Control Conference (1987)
Bait stations made with polyvinylchloride (PVC) pipe were compared with hand-broadcast applications of rodenticides for achieving long-term control of pine and meadow vole populations (Microtus pinetorum and M. pennsylvanicus, respectively) in two apple orchards in the mid-Hudson Valley of New York. The stations were constructed of three pieces of 1.5-in diameter PVC tubing joined together in the shape of an inverted "T". Roofing shingles were placed over the entrances to some of the bait stations to encourage use by voles, while others were left uncovered. All stations were tied to trees, with no attempt to place them near …
Landowner Perceptions Of Beaver Damage And Control In Arkansas, T.B. Wigley, M.E. Garner
Landowner Perceptions Of Beaver Damage And Control In Arkansas, T.B. Wigley, M.E. Garner
Third Eastern Wildlife Damage Control Conference (1987)
Landowner perceptions of damage caused by beavers (Castor canadensis) and of beaver control programs in Arkansas were determined by mail survey. Beavers were present on lands owned by 36% of the 1,716 respondents. Girdled timber, blocked culverts and flooded timber were the first, second and third most common damages reported, respectively. Thirty-two percent of all respondents and 90% of those with beavers reported at least one form of damage. Four percent of land owned by respondents was flooded by beavers. Of landowners with beavers, 50% described damage as substantial or severe, and 46% perceived damage as unreasonable. At …
Control Of Ring-Billed Gull Colonies At Urban And Industrial Sites In Southern Ontario, Canada, H. Blokpoel, G.D. Tessier
Control Of Ring-Billed Gull Colonies At Urban And Industrial Sites In Southern Ontario, Canada, H. Blokpoel, G.D. Tessier
Third Eastern Wildlife Damage Control Conference (1987)
At eight urban or industrial sites in southern Ontario colonies of Ring-billed Gulls (Larus delawarensis) were controlled to ameliorate problems caused by the adults and their young. At the Nanticoke Generating Station on Lake Erie a growing colony was eliminated by collecting eggs and subsequent harassment of adults. One colony at the Stelco Yards in Hamilton Harbor was eliminated by installing a gull exclosure and collecting eggs from nests outside the exclosure and another was controlled by frequently destroying nests and eggs. At Toronto Island Airport an incipient colony was controlled by collecting eggs and harassing adults. At …
Use Of Drc 1339 To Control Crows In Three Roosts In Kentucky And Arkansas, Frank L. Boyd, Douglas I. Hall
Use Of Drc 1339 To Control Crows In Three Roosts In Kentucky And Arkansas, Frank L. Boyd, Douglas I. Hall
Third Eastern Wildlife Damage Control Conference (1987)
Field tests utilizing DRC 1339 (3- chloro-4-methylbenzamine hydrochloride) 98% concentrate on whole kernel corn for crow (Corvus brachyrhynchos) control were conducted in January and February 1981 in Lexington and Louisville, Kentucky, and in 1982 in Ashdown, Arkansas. Treated bait was placed in staging areas near the roosts after pre-baiting indicated good acceptance at the sites. The rate of acceptance varied with bait placement. Best results were obtained when bait was placed on bare ground at habitually used staging areas close to the roost site. Population reductions of up to 25% were obtained with limited baiting. DRC 1339 appears …
The Critter Control Concept Approaches Of A Firm Specializing In Nuisance Wildlife Control, Lynn Braband, Kevin Clark
The Critter Control Concept Approaches Of A Firm Specializing In Nuisance Wildlife Control, Lynn Braband, Kevin Clark
Third Eastern Wildlife Damage Control Conference (1987)
The private sector has been involved in certain aspects of nuisance wildlife control for some time. Examples include commensal rodent control by pest control companies, capture of nuisance furbearers by trappers, and repair of structural damage by carpenters. Social trends, such as increased urbanization, increased population of certain wildlife species, and decreased government funding have combined to provide increased opportunity and need for the private sector in nuisance wildlife control. Critter Control, Inc. has sought to bring an integrated and specialized approach to nuisance wildlife control. Our general approach includes consultation on the nature of the nuisance situation, removal of …
The Problem Of Planting Louisiana Swamplands When Nutria(Myocastqr Coypu) Are Present, W.H. Conner, J.R. Toliver
The Problem Of Planting Louisiana Swamplands When Nutria(Myocastqr Coypu) Are Present, W.H. Conner, J.R. Toliver
Third Eastern Wildlife Damage Control Conference (1987)
Logging of baldcypress (Taxodium distichum) in the swamps of the southeastern United States is once again becoming common and an area of particular concern in Louisiana is the regeneration of cypress in its natural environment. One way to ensure the proper stocking of cypress is to plant seedlings, but nutria usually damage or destroy newly planted seedlings and are a deterrent to cypress regeneration in flooded areas. In 1985 cypress seedlings were planted in a flooded logged area and in an area where flooding was preventing the establishment of natural seedlings. Nutria destroyed 86% of the seedlings in …
Effectiveness Of Human Hair, Bgr, And A Mixture Of Blood Meal And Peppercorns In Reducing Deer Damage To Young Apple Trees, Michael R. Conover, Gary S. Kania
Effectiveness Of Human Hair, Bgr, And A Mixture Of Blood Meal And Peppercorns In Reducing Deer Damage To Young Apple Trees, Michael R. Conover, Gary S. Kania
Third Eastern Wildlife Damage Control Conference (1987)
We evaluated the ability of three repellents [human hair, Big Game Repellent (BGR), and a mixture of blood meal and peppercorns] to reduce deer damage on young apple trees in two Connecticut orchards. Most of the deer damage consisted of winter browsing on dormant apple buds. Little browsing occurred on leaves or buds during the growing season and only a few cases of pre-rut rubbing of trees were observed. In one orchard, buds were browsed during the winter on 52% of the untreated control trees, 45% of the trees sprayed with BGR, and 40% of the trees containing a hair …
Catch Effectiveness And Selectivity Of Several Traps, Edward P. Hill
Catch Effectiveness And Selectivity Of Several Traps, Edward P. Hill
Third Eastern Wildlife Damage Control Conference (1987)
The effectiveness and selectivity of several traps and trap Modifications were field-evaluated and compared in Alabama from 1977 to 19B0. No. 220 Conibear traps placed in baited open-end boxes (TB) on the ground posed a hazard to dogs and were not recommended for general use in terrestrial sets. They may be effective to control feral dogs in special situations or areas. TB devices attached to tree trunks 1 m above the ground eliminated the hazard to dogs, but rendered the trap ineffective for taking small mammals. No. 220 Conibear traps with selective position treadle triggers placed in trail water-sets were …
Status Of The Coyote In The Southeastern United States, Edward P. Hill
Status Of The Coyote In The Southeastern United States, Edward P. Hill
Third Eastern Wildlife Damage Control Conference (1987)
The range of the coyote (Canis latrans) in the southeastern United States, particularly east of the Mississippi River, has recently expanded. Although populations were present in Arkansas and Louisiana in the 1960s, only isolated individuals were known to exist east of the river before 1975. In addition to Arkansas and Louisiana, the present range includes Mississippi and Alabama, the western three fourths of Kentucky and Tennessee, Northwestern Florida, south-central and northwest Georgia and scattered portions of Maryland, West Virginia, Virginia, North and South Carolina, and Peninsular Florida. Recent literature indicates that several releases have influenced the rate of …
Methiocarb-Treated Rice Seed Applied After Field Draining Fails To Repel Blackbirds From Sprouting Rice, N.R. Holler, P.W. Lefebvre, R.E. Matteson, G.R. Gunknecht, R.A. Dolbeer
Methiocarb-Treated Rice Seed Applied After Field Draining Fails To Repel Blackbirds From Sprouting Rice, N.R. Holler, P.W. Lefebvre, R.E. Matteson, G.R. Gunknecht, R.A. Dolbeer
Third Eastern Wildlife Damage Control Conference (1987)
Blackbirds, primarily Agelaius phoeniceus, cause extensive losses to sprouting rice in southwestern Louisiana. Methiocarb applied to seed prior to planting at rates above 1.0 g a.i./kg rice (0.1%) has provided excellent protection to sprouting rice in Louisiana under conditions of high bird pressure. To reduce treatment costs, some farmers have used over-flights of methiocarbtreated seed applied at low rates to part of the field after draining. This study showed this technique was not efficacious under conditions of high bird pressure. Four fields treated in this manner suffered 98% loss of sprouts compared to 100% loss in four untreated fields. Large …
Use Of Soybean Fields In Eastern Virginia By White-Tailed Deer, Linda A. Lyon, Patrick F. Scanlon
Use Of Soybean Fields In Eastern Virginia By White-Tailed Deer, Linda A. Lyon, Patrick F. Scanlon
Third Eastern Wildlife Damage Control Conference (1987)
White-tailed deer (Odocoileus virginianus) use of soybean fields in Virginia was observed during the 1983 and 1984 growing seasons. Total deer observed and deer seen per observer-hour were both greater in 1983 (199 and 2.1, respectively) than in 1984 (122 and 1.8, respectively). The number of deer seen per observer-hour was related to crop phenology; it was highest during the early vegetative stages and decreased when the soybean plants entered reproductive growth stages. Most (90%) deer were sighted within 50 m of edge cover. In both years, the number of adult does seen was about 3 times the …

A State-Administered User-Pay Program For Nuisance Wildlife Control, Dale W. May
Third Eastern Wildlife Damage Control Conference (1987)
In recent years Connecticut, like many other northeastern states, has experienced dramatic suburban encroachment into woodland and farmland areas. The expansion of human population and the accompanying habitat alteration have resulted in a substantial increase in the frequency of wildlife/human conflicts. The Department of Environmental Protection's Wildlife Bureau, mandated to respond to the needs of the people as well as the wildlife of Connecticut, is the state agency given the responsibility of controlling nuisance wildlife problems. Although the Wildlife Bureau provides free technical assistance and educational material, in many cases landowners are either unwilling or unable to resolve nuisance wildlife …
Research Needs In Education And Research Institutions, Jay B. Mcaninch
Research Needs In Education And Research Institutions, Jay B. Mcaninch
Third Eastern Wildlife Damage Control Conference (1987)
Research to support wildlife management programs has traditionally been conducted by scientists in education and research institutions. Much of this work has resulted from state and federal agency program needs or has been funded by state or federal agencies upon solicitation from scientists at these institutions. Regardless of the origin of the research, these institutions have primarily provided the investigators and staff for conducting research on animal damage problems. The priorities, duration and depth of the efforts have been dependent upon the commitment to damage control research by the investigator and the quality of funding support.
Wolf, Golden Eagle, And Coyote Problems In Montana, B.W. O'Gara, W. Rightmire
Wolf, Golden Eagle, And Coyote Problems In Montana, B.W. O'Gara, W. Rightmire
Third Eastern Wildlife Damage Control Conference (1987)
The average annual reported loss of sheep and lambs to predators in Montana from 1982 through 1986 was 46,000 animals worth $1,980,000. During recent years, coyote predation has been the single most important cause of death for lambs. Coyotes accounted for 80% of the predator kills during 1985 and 72% during 1986, and 8,321 coyotes were killed by ADC during those 2 years. Aerial gunning accounted for more than half of the kills. During the first year of a study on a ranch in western Montana without predator control, coyotes killed 8% of the ewes and 27% of lambs. Predation …
Lethal Roost Toxicants For Control Of Starlings And Blackbirds, Denver L. Otis
Lethal Roost Toxicants For Control Of Starlings And Blackbirds, Denver L. Otis
Third Eastern Wildlife Damage Control Conference (1987)
Roosting congregations of starlings (Sturnus vulgaris) and several blackbird species (Icteridae) cause several millions of dollars in losses to agricultural crops throughout the United States. In addition, they are responsible for a variety of nuisance problems, human and livestock diseases, and human safety hazards. Dozens of tools have been developed for alleviating these problems, some of which are nonlethal techniques aimed at either roost dispersal or site specific protection of the problem site. Lethal baiting techniques for use at staging areas or at the problem site have also been developed. However, the most controversial solution involves the use …
Coyote Control Techniques And Their Applications In The Eastern United States, Rick D. Owens
Coyote Control Techniques And Their Applications In The Eastern United States, Rick D. Owens
Third Eastern Wildlife Damage Control Conference (1987)
Conflicts between coyotes and man's activities are varied and include such problems as predation on livestock, agricultural crops, and other wildlife, as well as threats to human health or safety. Formerly restricted to the Great Plains, the coyote's adaptability has enabled expansion of its population throughout most of the United States, Canada and Mexico. This expansion has occurred in spite of large-scale control and/or eradication efforts. In the West, coyote management includes non-lethal as well as lethal techniques. Non-lethal approaches, which have resulted in varying degrees of success, include the use of guarding dogs, fencing, and shedding. In many instances, …

Effects Of Differential Pine Vole Populations On Growth And Yield Of 'Mcintosh’ Apple Trees, M.E. Richmond, C.G. Forshey, L.A. Mahaffy, P.N. Miller
Third Eastern Wildlife Damage Control Conference (1987)
Pine voles (Microtus pinetorum LeConte) were maintained as known populations (0, 269, 538 and 1075/ha) in wire mesh-enclosed blocks of 'Mclntosh'/M26 apple trees (Malus domestica Borkh) for 2 years. There was little measurable effect of the voles on growth and production the 1st year, but during the 2nd year the highest population was associated with the death of one tree; severe reductions in growth, yield, and fruit size; a 78% reduction in crown bark weight, 56% loss of fibrous roots, and a dramatic reduction in the value of the crop. Although the low and the medium …
The Use Of The T-Culvert Guard To Protect Road Culverts From Plugging Damage By Beavers, K.J. Roblee
The Use Of The T-Culvert Guard To Protect Road Culverts From Plugging Damage By Beavers, K.J. Roblee
Third Eastern Wildlife Damage Control Conference (1987)
Since 1978 there has been a continual effort by Region 9 of the New York State Department of Environmental Conservation to develop devices capable of protecting road culverts from plugging damage by beavers (Castor canadensis). Various protective devices were developed. The most successful was the T-culvert guard. Trial installations of T-culvert guards were made at 4 sites experiencing beaver damage. T-culverts consisted of a 4 ft. or larger diameter culvert and a smaller diameter culvert which connected it to the road culvert . Directions for construction, installation and maintenance of T-culverts are given. Costs for a typical 4 …
Cooperative Beaver Control: Usfws-Adc And Private/Industrial Landowners, K. F. Rohr
Cooperative Beaver Control: Usfws-Adc And Private/Industrial Landowners, K. F. Rohr
Third Eastern Wildlife Damage Control Conference (1987)
Beaver populations in North Miss, and West Tenn. have increased rapidly, Pelt trapping has been the major control method in the past. With low demand and poor prices for southern pelts, this activity is almost nonexistent today. Landowners, both private and industrial, have tried several control methods with limited success. Few landowners have the expertise or the time to perform their own control work. What is needed is an agency with the expertise and the supervisory capacity to administer the program for the landowner. The Animal Damage Control Unit of USDA entered into a cooperative agreement with an industrial landowner …
Extension's Perspective Of Federal, State And Private Animal Damage Control Programs, Gary J. San Julian
Extension's Perspective Of Federal, State And Private Animal Damage Control Programs, Gary J. San Julian
Third Eastern Wildlife Damage Control Conference (1987)
Extension personnel are in a unique position to observe and to be involved in animal damage control (ADC) programs at the federal, state and private levels. In order to offer educational programs, we must interpret regulations and policies to provide a workable interface between ourselves, other agencies and the public. This is not an easy task in such a sensitive and emotional area. The lack of uniformity in policies among federal agencies as well as the hazy lines of authority and responsibility for some species makes it hard to provide guidance for our clientele. The growing involvement of the public …
