Application Strategy For An Anthraquinonebased Repellent And The Protection Of Soybeans From Canada Goose Depredation, Scott J. Werner, Matthew Gottlob, Charles D. Dieter, Joshua D. Stafford Oct 2019

Application Strategy For An Anthraquinonebased Repellent And The Protection Of Soybeans From Canada Goose Depredation, Scott J. Werner, Matthew Gottlob, Charles D. Dieter, Joshua D. Stafford

USDA Wildlife Services: Staff Publications

Agricultural crops can sustain extensive damage caused by Canada geese (Branta canadensis) when these crops are planted near wetlands or brood-rearing sites. From 2000 to 2015, South Dakota Game, Fish and Parks spent >$5.6 million to manage damages caused by Canada geese to agricultural crops (primarily soybeans) in South Dakota, USA. For the purpose of developing a repellent application strategy for nonlethal goose damage management, we comparatively evaluated the width of anthraquinone applications (i.e., 9.4 L Flight Control® Plus goose repellent/ha [active ingredient: 50% 9,10-anthraquinone] at 0–36 m versus 0–73 m perpendicular to the edge of wetlands in 2014), the …


Did Predator Control Go To The Dogs? A 40-Year Retrospective, John M. Tomeček Jan 2019

Did Predator Control Go To The Dogs? A 40-Year Retrospective, John M. Tomeček

Human–Wildlife Interactions

In 1980, Green and Woodruff published an article entitled, “Is Predator Control Going to the Dogs?” At that time, the use of Livestock Guardian Dogs (hereafter LGDs) was a relatively new wildlife damage management tool in North America. Although this tool passed the test of time in its point of origin, early North American adopters stepped into a brave new world with little to guide them. In the modern world, knowledge of methods and means of wildlife damage management exists in written texts, films, and other guides. For LGDs, however, such materials did not exist 40 years ago. Over the …


Movement Responses Inform Effectiveness And Consequences Of Baiting Wild Pigs For Population Control, Nathan P. Snow, Kurt C. Vercauteren Jan 2019

Movement Responses Inform Effectiveness And Consequences Of Baiting Wild Pigs For Population Control, Nathan P. Snow, Kurt C. Vercauteren

USDA Wildlife Services: Staff Publications

Wild pigs (Sus scrofa) damage agricultural and natural resources throughout their nearly global distribution. Subsequently, population control activities (e.g., trapping, shooting, or toxic baiting) frequently involve the deployment of bait to attract wild pigs. A better understanding of how wild pigs respond to bait sites can help maximize efficiency of baiting programs and identify any potential pitfalls. We examined the movement behaviors of 68 wild pigs during three stages of intensive baiting programs (i.e., 15 days each: prior, during, and post baiting) spread across two distinct study areas in southern and northern Texas, USA. We found that bait sites needed …


Factors Influencing The Movement Of Livestock Guardian Dogs In The Edwards Plateau Of Texas: Implications For Efficacy, Behavior, And Territoriality, John M. Tomeček, Justin T. French, John W. Walker, Nova J. Silvy, Nicholas A. Bromen Jan 2019

Factors Influencing The Movement Of Livestock Guardian Dogs In The Edwards Plateau Of Texas: Implications For Efficacy, Behavior, And Territoriality, John M. Tomeček, Justin T. French, John W. Walker, Nova J. Silvy, Nicholas A. Bromen

Human–Wildlife Interactions

Livestock guardian dog (Canis lupus familiaris; LGD) breeds of domestic dog worldwide provide a degree of control over predation losses. The application of LGDs as a wildlife damage management tool evolved as a cultural practice in the Old World. In the 1970s, this tool emerged in North America. Despite several decades of science and application, gaps still exist in our knowledge regarding applications for LGDs. From February 2016 to November 2017, we deployed global positioning system transmitters on 4 LGDs on a 20-km2 ranch in Menard County, Texas, USA operated by Texas A&M AgriLife Research to investigate …
