Wildlife-Caused Losses Of Agricultural Commodities In 1994 With Emphasis On The Great Plains, A.P. Wywialowski
Wildlife-Caused Losses Of Agricultural Commodities In 1994 With Emphasis On The Great Plains, A.P. Wywialowski
Great Plains Wildlife Damage Control Workshop Proceedings
The USDA, National Agricultural Statistics Service (NASS) surveyed 16,000 agricultural producers in January 1995. Of 10,144 respondents nationwide, 58% reported wildlife-caused losses of their commodities, an increase from 55% in 1989. Based on the median value of all producers' estimates of their losses, wildlife-caused losses cost producers approximately $591 million in 1994, $130 million more than in 1989. Losses presented are based on median producer estimates which have been shown to be consistent with field-measured estimates of damage. Because the dollar value of losses are based on median estimates, extremes of reported losses do not affect these results. If all …
Impact Of Preventive Aerial Coyote Hunting On Sheep Losses To Coyote Predation, Kimberly K. Wagner, Michael R. Conover
Impact Of Preventive Aerial Coyote Hunting On Sheep Losses To Coyote Predation, Kimberly K. Wagner, Michael R. Conover
Great Plains Wildlife Damage Control Workshop Proceedings
Coyote (Canis latrans) predation is a serious problem for livestock producers in the Western U.S. In Utah, Idaho, and Wyoming, 34% of all producer-reported sheep and lamb losses were to coyote predation, amounting to $4.8 million in losses during 1995. Although preventive aerial hunting is commonly used by agriculture agencies in the Intermountain West to reduce coyote (Canis latrans) predation on sheep (Ovis aries), only limited data are available on the efficacy of the technique. We assessed the impact of winter (January - March) aerial coyote hunting on sheep losses to coyotes and the …
Development And Registration Of A Practical Tranquilizer Trap Device (Ttd) For Foot-Hold Traps, Doris E. Zemlicka, D. Pete Sahr, Peter J. Savarie, Frederick F. Knowlton, F. Sherman Blom, Jerrold L. Belant
Development And Registration Of A Practical Tranquilizer Trap Device (Ttd) For Foot-Hold Traps, Doris E. Zemlicka, D. Pete Sahr, Peter J. Savarie, Frederick F. Knowlton, F. Sherman Blom, Jerrold L. Belant
Great Plains Wildlife Damage Control Workshop Proceedings
Foot-hold traps can be used to selectively capture coyotes (Canis latrans) and wolves (C. lupus). However, injuries to captured animals sometimes occur when they struggle to escape. Tranquilizer trap devices (TTDs) reduce struggling and injuries but prototype TTDs were too expensive for widespread use by Animal Damage Control (ADC) operational personnel. For this reason, the Pocatello Supply Depot (PSD) and the National Wildlife Research Center (NWRC) are investigating alternative TTD designs. A molded-rubber TTD will be available from the PSD for coyotes, and the NWRC continues to explore other cheaper TTD designs. A practical TTD design …
The Coyote As An Ecological Model, Thomas A. Eddy, Cindy M. Moore
The Coyote As An Ecological Model, Thomas A. Eddy, Cindy M. Moore
Great Plains Wildlife Damage Control Workshop Proceedings
Teachers (K-12) in a prairie ecology workshop in Kansas used the coyote as the focus for the design of an educational strategy to integrate many concepts and principles of ecology into the various subject areas of the curriculum. A topical outline was developed as a guide for implementing the study.
