Field Evaluation Of Chemical Attractants For Summer Use On M-44s1, Robert L. Phillips, F. Sherman Blom
Field Evaluation Of Chemical Attractants For Summer Use On M-44s1, Robert L. Phillips, F. Sherman Blom
Vertebrate Pest Conference Proceedings: 16th (1994)
Responses of free-roaming coyotes (Canis latrans) to four chemical attractants (W-U lure, artificial beef liver flavor, artificial smoked fish flavor, and Fatty Acid Scent) used on M-44 tops were measured during the summer months in Colorado, Idaho, Montana, Washington, and Wyoming. Visitation and pull rates varied throughout the study period from area to area and appeared to be associated with weather, food abundance, and coyote densities. Fatty Acid Scent and W-U lure produced the highest visitation and pull rates.

The Animal Damage Control program has been heavily involved in strategic planning since its transfer from USDI to USDA. The first effort was undertaken in 1989 by the program's management team. It was an introspective, critical look at what changes were needed to improve the program's strategic position in the natural resources community. That plan failed to achieve the desired objective due principally to the lack of involvement by ADC employees and others outside the program. In 1991, a more comprehensive effort was begun known as "Futuring." In this process, a representative from each organizational level of the program and …
Bear Relocations To Avoid Bear/Sheep Conflicts, Alan R. Armistead, Ken Mitchell, Guy E. Connolly
Bear Relocations To Avoid Bear/Sheep Conflicts, Alan R. Armistead, Ken Mitchell, Guy E. Connolly
Vertebrate Pest Conference Proceedings: 16th (1994)
Preventive relocation of black bears (Ursus americanus) was tried as an alternative to lethal removal of bears that attacked sheep in northeastern Oregon. Bears in likely problem areas or in close proximity to sheep bands were captured with culvert traps and moved to other ranges without sheep. Sixteen bears were relocated in 1990 and five in 1991 from areas where five damaging bears had been destroyed in 1989. The five bears relocated in 1991 were radio collared and monitored by the Oregon Department of Fish and Wildlife. None of them were involved in livestock depredations subsequent to relocation. Sheep losses …
Stowaway Transport Rates Of House Mice (Mus Domesticus) And Deermice (Peromyscus Maniculatus)*, Ann Eileen Miller Baker
Stowaway Transport Rates Of House Mice (Mus Domesticus) And Deermice (Peromyscus Maniculatus)*, Ann Eileen Miller Baker
Vertebrate Pest Conference Proceedings: 16th (1994)
Stowaway transport rates were obtained from behavioral observations of 14 house mice (Mus domesticus) and 14 deermice (Peromyscus maniculatus) during commercial transport. One house mouse escaped during unloading and flaking of 2,500 kg 2-year old oat hay. Three house mice and two deermice were hand-caught on trucks during unloading of 51,110 kg transported barley straw and grass hay. One house mouse was hand-caught after being buried alive in grain. Two house mice escaped during unloading of a semitruck holding dog food. House mice (one live, six recently-dead) and deermice (two recently-dead) were taken from a feedmill screen over which had …
Field Tests Of A Copper-Based Fungicide As A Bird Repellent Rice Seed Treatment, Michael L. Avery, M.O. Way
Field Tests Of A Copper-Based Fungicide As A Bird Repellent Rice Seed Treatment, Michael L. Avery, M.O. Way
Vertebrate Pest Conference Proceedings: 16th (1994)
In east Texas, bird damage to sprouting rice was reduced in two of seven study plots when rice seed was treated with the fungicide Kocide® SD at the maximum label rate (8 fluid oz/100 1b seed). Foraging rates of male red-winged blackbirds (Agelaius phoeniceus) in treated plots were lower (P = 0.02) than were those in control plots. We suspect that the copper in Kocide SD produces physiological effects that suppress feeding activity that results in reduced losses in some cases. Because it is registered for use on rice and is relatively inexpensive, Kocide SD may be a useful component …
Blurred Images: And The Future Of Wildlife Damage Management , Jack H. Berryman
Blurred Images: And The Future Of Wildlife Damage Management , Jack H. Berryman
Vertebrate Pest Conference Proceedings: 16th (1994)
The paper points out a number of perceptions that blur and damage the image of wildlife damage management and their importance to the future. Some of the reasons for the perceptions are suggested and a number of steps suggested to improve the public image. It concludes on a note of optimism for the future.
Resistance To The First And Second Generation Anticoagulant Rodenticides-A New Perspective, A.P. Buckle, C.V. Prescott, K.J. Ward
Resistance To The First And Second Generation Anticoagulant Rodenticides-A New Perspective, A.P. Buckle, C.V. Prescott, K.J. Ward
Vertebrate Pest Conference Proceedings: 16th (1994)
Warfarin resistance was first discovered among Norway rat (Rattus norvegicus) populations in Scotland in 1958 and further reports of resistance, both in this species and in others, soon followed from other parts of Europe and the United States. Researchers quickly defined the practical impact of these resistance phenomena and developed robust methods by which to monitor their spread. These tasks were relatively simple because of the high degree of immunity to warfarin conferred by the resistance genes. Later, the second generation anticoagulants were introduced to control rodents resistant to the warfarin-like compounds, but resistance to difenacoum, bromadiolone and brodifacoum is …
An Evaluation Of Anti-Coyote Electric Fences, Robert C. Acorn, Michael J. Dorrance
An Evaluation Of Anti-Coyote Electric Fences, Robert C. Acorn, Michael J. Dorrance
Vertebrate Pest Conference Proceedings: 16th (1994)
We interviewed 21 sheep farmers and evaluated their electric fences to identify problems and determine efficacy of electric fences to prevent coyote (Canis latrans) predation. Modified woven wire fences and fences of 9 high-tensile smooth wires alternating charged and grounded were most effective in preventing coyote predation. The most serious problems in fence design and maintenance were a) bottom charged wire too high above ground level, b) wires spaced too far apart, and c) inadequate vegetation control.
