Relocation Of City Raccoons, Richard C. Rosatte, Charles D. Macinnes
Relocation Of City Raccoons, Richard C. Rosatte, Charles D. Macinnes
Great Plains Wildlife Damage Control Workshop Proceedings
Twenty-four city raccoons were radio-collared and relocated 25-45 km north of the original capture site in Toronto, Ontario. Following release, extensive exploratory movements were noted with distances of 2-7 km being traversed per night. Home ranges for adult males (avg = 39 km2) and females ( avg = 72 km2) far exceeded juvenile ranges and areas utilized by raccoons in an urban setting. None of the raccoons returned to the original point of capture and mortality of the relocated raccoons approached 50% during the first 3 months following release
The Use Of Dma To Reduce Robin Depredation On Cherries, Leonard R. Askham, John K. Fellman
The Use Of Dma To Reduce Robin Depredation On Cherries, Leonard R. Askham, John K. Fellman
Great Plains Wildlife Damage Control Workshop Proceedings
The use of a biorational pesticide, Dimethyl Anthrantlate (DMA), was investigated for possible use as a robin repellant in an Eastern Washington Research orchard. Applied in low concentrations (2, 4, and 8% with surfactant), robin depredation was reduced an average of 75%. A double-blind taste test showed no consumer aversion for fresh fruit sprayed with DMA two weeks before harvest.

Seasonal Variation In Habitat Use By Great-Tailed Grackles In The Lower Rio Grande Valley, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Alan R. Tipton, Nancy Koerth
Great Plains Wildlife Damage Control Workshop Proceedings
Habitat use by great-tailed grackles was measured by performing weekly censuses of birds in 6 different habitat types: chaparral, citrus groves, feed lots, pastures, residential areas, and agricultural fields. We found that use of chaparral, citrus, and residential sites was low during the winter months, increased sharply with commencement of the nesting season in April, and declined again by October. Use of agricultural fields and pasture was irregular. Feed lot use was low during the summer, but high from October - April with October and March migration peaks. An overall sex ratio of 1.3 females/male was observed with skews from …

Great Plains Wildlife Damage Control Workshop Proceedings
I evaluated the effectiveness, suitability, and expense of 2 styles of predator guards for black-bellied whistling duck (Dendrocyqna autumnalis) nest-boxes. Guards evaluated were galvanized bottom attached shrouds and razor-ribbon wire. Both guards were effective against ground dwelling predators. The group not fitted with guards suffered a 55% overall depredation rate.
Experimental Applications Of High-Tensile Wire And Other Fencing To Control Big Game Damage In Northwest Colorado, A. Eugene Byrne
Experimental Applications Of High-Tensile Wire And Other Fencing To Control Big Game Damage In Northwest Colorado, A. Eugene Byrne
Great Plains Wildlife Damage Control Workshop Proceedings
Conventional fencing methods V-mesh wire, square mesh wire and wood panels are compared to experimental methods - 15 wire hightensile wire fences; electric high-tensile wire fences of three designs; baited electric fences; hog panel fences; plastic mesh fences and visqueen wrapped haystacks. Total cost of materials, cost per ft./yr. and comments concerning estimates of efficacy are discussed. The V-mesh wire, hog panel and plastic mesh fences all have a very high cost per ft. and cost per ft./yr. rating and should probably not be used. High-tensile and square mesh wire fences are effective and cheaper alternatives. Modern high-tensile wire electric …

Trophy Game Animal Damage In Wyoming, Ron Iversons
Trophy Game Animal Damage In Wyoming, Ron Iversons
Great Plains Wildlife Damage Control Workshop Proceedings
Wyoming is perhaps one of the most liberal and unique states of the fifty states on compensation for game and trophy game animal damage. Trophy game animals as defined by statute in Wyoming includes the Cougar (Mt. Lion), Black Bear, and the Grizzly Bear. According to statute Wyoming is responsible for damages incurred by these species to livestock, land, crops, improvements, and extraordinary grasses. Since the statutes were enacted Wyoming has been faced with a variety of complaints and damage claims caused by these species. Damage complaints received by the Department have covered a broad spectrum, ranging from the stockman …

Characteristics Of Deer Damage To Experimental Orchards In Ohio, Kerry J. Mower, Thomas W. Townsend, William J. Tyznik
Great Plains Wildlife Damage Control Workshop Proceedings
We measured several variables of newly established apple trees (1) to compare growth differences between trees damaged by browsing deer and trees protected from deer, (2) to determine if seasonal browsing patterns existed, and (3) to determine if deer browsed selectively among Ohio's 3 most commonly planted apple cultivars. All testing was die at the 0.05 alpha level. Experimental trees were measured repeatedly from June 1986 the May 1988.
Management Problems Encountered With Livestock Guarding Dogs On The University Of California, Hopland Field Station, Robert M. Timm, Robert H. Schmidtz
Management Problems Encountered With Livestock Guarding Dogs On The University Of California, Hopland Field Station, Robert M. Timm, Robert H. Schmidtz
Great Plains Wildlife Damage Control Workshop Proceedings
Guard dogs are being promoted and utilized as effective predator damage control tools under a variety of livestock management conditions. We report our experience over 1 1/2 years with 5 dogs, primarily Anatolian shepherd and Akbash dog breeds. We discuss a number of behavioral and management problems we have encountered, some of which have not previously been reported in the literature. These include chasing vehicles and wildlife, predation on deer (Odocoileus hemionus columbianus), and incompatibility of dogs with other predator damage control methods.

Kansas Attitudes On Prairie Dog Control, Charles D. Lees, F. Robert Henderson
Kansas Attitudes On Prairie Dog Control, Charles D. Lees, F. Robert Henderson
Great Plains Wildlife Damage Control Workshop Proceedings
In Kansas prairie dog management is primarily determined by private individuals and local government agencies. We conducted a mail survey of 350 affected landowners as a means to evaluate the effectiveness of current prairie dog control. The same survey was also sent to 350 randomly selected state residents within the general prairie dog range. We evaluated people's perceptions of prairie dogs, the effectiveness of control methods, costs of control, and reasons for poor response to control techniques. Results indicate people that have previously been involved in prairie dog control on lands they manage have different opinions about prairie dogs than …
Black-Footed Ferret Recovery, Dean E. Biggins, Ronald A. Crew
Black-Footed Ferret Recovery, Dean E. Biggins, Ronald A. Crew
Great Plains Wildlife Damage Control Workshop Proceedings
The captive population of black-footed ferrets increased from 24 to 58 animals in 1988, and was split to provide the species added protection against extinction. Experimental reintroductions may begin in 1991. In some areas, "experimental population" designations as authorized under Section 10 (j) of the Endangered Species Act may be used to provide wider management latitude. The Black-footed Ferret Interstate Coordinating Committee oversees much of the work related to reintroduction. Expanded effort to locate wild ferrets now includes a $10,000 reward offer. Research focuses on captive breeding, reintroduction techniques, disease, and habitat. A new Recovery Plan was approved in 1988.

An Assessment Of The Urban Wildlife Problem, William D. Fitzwater
An Assessment Of The Urban Wildlife Problem, William D. Fitzwater
Great Plains Wildlife Damage Control Workshop Proceedings
Basic urban wildlife problems include: proper identification of species, shift from agrarian to urban society, different interpretations of humaneness, compassion for individual rather than a population as a whole, and public ignorance of urban pest management. Positive values are esthetics and environmental education opportunities. Negative values are disease transmission, life/injury-threatening situations, damage to buildings/other property, water structures/quality, petty annoyances, and indirect economics.
Aphis Animal Damage Control Livestock Guarding Dog Program, Jeffrey S. Green
Aphis Animal Damage Control Livestock Guarding Dog Program, Jeffrey S. Green
Great Plains Wildlife Damage Control Workshop Proceedings
One hundred traditional breed livestock guarding dog pups were placed with sheep producers in Wyoming, Idaho, Oregon, and Washington during 1987-88 as part of the APHIS Animal Damage Control program. Producers reared the dogs and integrated them into their operations. Ninety-three dogs were rated as follows: 68% good, 17% fair, and 15$ poor. Success was breed-related. Sixty-one percent of the dogs were used on pasture operations and 39% on range operations. Nineteen percent of the dogs died prior to reaching 18 months-of-age.

Estimating Domestic Sheep Losses To Mountain Lions, Frederick G. Lindzey, Connie Wilbur
Great Plains Wildlife Damage Control Workshop Proceedings
Large, native-range pastures were searched for dead domestic sheep in the Southern Bighorn Mountains of Wyoming. The proportion of dead sheep that had been killed by mountain lions was 23%. Search methods, however, resulted in unequal probabilities of finding sheep that were killed by mountain lions and sheep that died of other causes.
Habitat Manipulations To Prevent Elk Damage To Private Rangelands, William M. Long
Habitat Manipulations To Prevent Elk Damage To Private Rangelands, William M. Long
Great Plains Wildlife Damage Control Workshop Proceedings
Habitat manipulations were initiated on the Wick Brothers big Game Winter range in southern Wyoming to alter traditional movement patterns of Rocky Mountain Elk (Cervus elaphus nelsonii) . Manipulations included spraying with 2-4-D and follow-up fertilization of the same plot in successive years with ammonium nitrate at the rate of 40 lbs. (18 kg.) free nitrogen per acre. Burning hay meadows and upland sagebrush sites and salting were used in combination with the other treatments. Elk distribution shifted to the treated plots in response to the increased quality and quantity of the grass production on these areas. Spring …

Seasonal Effects On Control Methods For The Great-Tailed Grackle, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores, John Hobbs, Joe Palacios
Great Plains Wildlife Damage Control Workshop Proceedings
Efficiency of methods used to control damage to citrus fruit by great-tailed grackles was found to vary considerably from season to season. From April - July, the birds congregated in small breeding colonies where they were susceptible to baiting and poisoning. From August - October, the birds could be baited in to and poisoned at watering sites. Intensive shooting and use of pyrotechnics were also used successfully at this time of year to control damage at groves with high grackle concentrations. From late October - March, birds moved over wide areas each day, and were easily frightened from groves by …
Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores
Effects Of Grackle Damage Control Techniques In Citrus On Nesting Success Of Non-Target Species, John H. Rappole, Wan R. Tipton, Arlo H. Kane, Rafael H. Flores
Great Plains Wildlife Damage Control Workshop Proceedings
Several techniques were tested to reduce the damage caused by great-tailed grackles to citrus in the lower Rio Grande Valley of southern Texas: monofilament line, eyespot balloons, pyrotechnics, and grackle nest removal. Ten species were found nesting in the treated groves, but only the mourning dove, white-winged dove, and great-tailed grackle in significant numbers. Nesting success was not reduced significantly by any treatment but observations indicate that cannon treatments are likely to have a negative impact on overall nesting success for several species.

Use Of Drc-1339 And Pa-14 To Control Grackle Populations In The Lower Rio Grande Valley, Alan R. Tipton, John H. Rappole, Arlo H. Kane, Rafael H. Flores, John Hobbs, Dave Johnson, Sam Beasom
Great Plains Wildlife Damage Control Workshop Proceedings
In an attempt to reduce valley wide populations of grackles in the Rio Grande Valley of South Texas, PA-14 was sprayed over a staging area where as many as 10,000 birds were located. This attempt was unsuccessful and this method of population reduction was deemed not suitable for south Texas. Dog food bait was treated with DRC-1339 and presented to great-tailed grackles in several different situations in an attempt to control depredations to citrus by this bird. Bait presented in feedlots during winter (Nov-Feb) was readily taken by the birds, resulting in a significant reduction of numbers of birds visiting …
Use Of Monofilament Line, Reflective Tape, Beach-Balls, And Pyrotechnics For Controlling Grackle Damage To Citrus, Alan R. Tipton, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Dave Johnson, John Hobbs, Paul Schulz, Sam Beasom, Joe Palacios
Use Of Monofilament Line, Reflective Tape, Beach-Balls, And Pyrotechnics For Controlling Grackle Damage To Citrus, Alan R. Tipton, John H. Rappole, Arlo H. Kane, Rafael H. Flores, Dave Johnson, John Hobbs, Paul Schulz, Sam Beasom, Joe Palacios
Great Plains Wildlife Damage Control Workshop Proceedings
The effectiveness of monofilament line, reflective tape, beach-balls and pyrotechnics (propane cannons and shotgun scare shells) in reducing damage to citrus by great-tailed grackles was tested in the lower Rio Grande Valley of southern Texas. Results indicate that these treatments can produce reduction in damage. Whether the treatments are economically advisable for a grower depends on the history of grackle damage to the grove and grove size. Only large amounts of damage in large groves justify costs associated with implementation of these methods.
Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans
Field Trials Of Alpha-Chloralose And Drc-1339 For Reducing Numbers Of Herring Gulls, Paul P. Woronecki, Richard A. Dolbeer, Thomas W. Seamans
Great Plains Wildlife Damage Control Workshop Proceedings
We compared the potential of Alpha-chloralose (A-C) and DRC-1339 to reduce a nesting population of herring gulls at an industrial site in Ohio in 1988. Almost all treated baits were consumed by gulls but only about one affected gull was noted for every 10 baits consumed of either chemical. A test indicated our DRC-1339 baits. containing 3.7 - 7.4 times the published LD value, were not lethal to most captive herring gulls living in fresh water. LD values of A-C and DRC-1339 need to be more precisely estimated for gull species in fresh and salt water environments.

Fall Food Habits Of Double-Crested Cormorants In Arkansas, Albert E. Bivings, Michael D. Hoy, Jeffrey W. Jones
Great Plains Wildlife Damage Control Workshop Proceedings
One hundred forty-eight double-crested cormorants (Phalacrocorax auritus) were collected in October-December 1988. Some were collected while actively feeding, but most were collected at loafing or roosting areas. Of the 135 with fish in them, 79% contained gizzard shad (Dorosoma cepedianum) and 16% contained centrarchids (mostly Lepomus sp.). The rest contained a variety of aquaculture (commercially raised) fish. Fish prey weights were estimated from total length of prey items and use of published length-weight tables. Total weights of prey ranged from 39 to 4558 with a mean of 185g. This was felt to be a conservative estimate …
