Cooperative Wolf Depredation Management In Wisconsin, Robert C. Willging, Adrian P. Wydeven
Cooperative Wolf Depredation Management In Wisconsin, Robert C. Willging, Adrian P. Wydeven
Great Plains Wildlife Damage Control Workshop Proceedings
A depredation management plan was an important component of Federal and State recovery plans for the endangered gray wolf (Canis lupus) in Wisconsin. The Wisconsin Department of Natural Resources (WDNR) entered into a cooperative agreement with USDA-APHIS-ADC to cooperatively manage wolf depredations. Response to complaints involving wolf-dog hybrids was also part of the cooperative agreement. From 1990-1996 ADC investigated 60 wolf complaints and confirmed 10 depredations. In the same time period, WDNR paid a total of $21,376 in compensation payments for 21 incidents of wolf depredations. Wolves may be downlisted from endangered to threatened within the next five …
Livestock Protection Collar Use In California, Robert M. Timm, Gary D. Simmons, John R. Hays
Livestock Protection Collar Use In California, Robert M. Timm, Gary D. Simmons, John R. Hays
Great Plains Wildlife Damage Control Workshop Proceedings
Use of the Livestock Protection Collar (LP Collar) containing sodium fluoroacetate began on a research basis in October 1995 at the UC Hopland Research and Extension Center. Registration for use in California only by certified ADC specialists was granted in early 1996, and operational use in three north coast counties began in early 1997. Preparation for beginning operational use dealt with concerns regarding user certification, hazardous waste disposal, and public relations. We report on the success to date of using LP Collars to remove sheep-killing coyotes. Incidents in which non-target predators including mountain lions have attacked LP-Collared sheep are also …
Environmental Assessment Of Wildlife Damage Control For Wildlife Protection, Michael J. Bodenchuk
Environmental Assessment Of Wildlife Damage Control For Wildlife Protection, Michael J. Bodenchuk
Great Plains Wildlife Damage Control Workshop Proceedings
Wildlife damage management for the protection of wildlife resources was common in the early days of wildlife management. It may once again become an important endeavor. The Utah Animal Damage Control program has conducted several projects for the protection of specific wildlife species. Case histories of these projects are discussed, and a wildlife damage management program which integrates resources as well as control technologies is presented.
Depredation Of Catfish By Double-Crested Cormorants At Aquaculture Facilities In Oklahoma, Robert L. Simmonds Jr., Alexander V. Zale, David M. Leslie Jr.
Depredation Of Catfish By Double-Crested Cormorants At Aquaculture Facilities In Oklahoma, Robert L. Simmonds Jr., Alexander V. Zale, David M. Leslie Jr.
Great Plains Wildlife Damage Control Workshop Proceedings
Oklahoma has about 324 ha of surface water in catfish (Ictalurus spp.) production. The state also supports a large number of migrating and wintering piscivorous birds, particularly double-crested cormorants (Phalacrocorax auritus). To address concerns of aquaculture facility operators regarding loss of fish to cormorants, we asked 11 operators to conduct regular counts of piscivorous birds at each facility. These data were used to determine factors affecting cormorant density at facilities and to estimate amount of catfish lost to cormorant depredation. Cormorant density (birds/ha/day) was positively correlated with surface area of water in production at facilities <10 ha (r = …10>
Wyoming's M-44 Program: An Overview And Assessment Of Private And Commercial Applicators, Henry R. Uhden
Wyoming's M-44 Program: An Overview And Assessment Of Private And Commercial Applicators, Henry R. Uhden
Great Plains Wildlife Damage Control Workshop Proceedings
Wyoming's legislation funding predator control has progressed from a bounty system, to a mill levy system, to the current fee assessment per head. The Wyoming Department of Agriculture administers an M-44 predator control program for private and commercial applicators' use with livestock depredators. As predatory impacts on livestock have increased, use of M- 44 has also broadened. The M-44 is a mechanical device utilizing a spring-activated ejector, that propels the dry toxicant sodium cyanide into the mouth of the target species when pulled. Death of the animal is accomplished by inhalation of hydrogen cyanide which forms when sodium cyanide comes …
