Feral Horses, Feral Asses, And Professional Politicians: Broodings From A Beleaguered Biologist, Vernon C. Bleich
Feral Horses, Feral Asses, And Professional Politicians: Broodings From A Beleaguered Biologist, Vernon C. Bleich
Human–Wildlife Interactions
As a member of National Wild Horse and Burro Advisory Board, I gained insight into several aspects of feral equid management that previously had been somewhat cryptic. Foremost in my experience, though, was the dedication and professionalism of the board members with whom I served. During my tenure, the professional approach to management and the frustration faced by employees within the Horse and Burro Program became increasingly apparent. Further came the realization that the effectiveness of the board and program can be improved substantially, if (1) the board is provided the opportunity to rebut or counter incorrect or misleading information …
Is Mitigation Translocation An Effective Strategy For Conserving Common Chuckwallas?, Chad A. Rubke, Daniel J. Leavitt, Woodrow L. Crumbo, Brock Williams, Ashley A. Grimsley-Padron, Kristin J. Gade, Russell Benford, Michael F. Ingraldi, Brian K. Sullivan, Ryan P. O’Donnell

Mitigation translocation remains a popular conservation tool despite ongoing debate regarding its utility for population conservation. To add to the understanding of the effectiveness of mitigation translocation, in 2017 and 2018 we monitored a population of protected common chuckwallas (Sauromalus ater) following translocation away from the area of construction of a new highway near the South Mountains, Phoenix, Arizona, USA. We removed chuckwallas from the construction right-of-way, paint-marked and pit-tagged them, and then released them in a nearby municipal preserve. We deployed very high frequency radio-telemetry transmitters on a sub-sample of 15 translocated adult chuckwallas. We monitored the …
Bear-Caused Human Fatalities In Yellowstone National Park: Characteristics And Trends, Kerry A. Gunther
Bear-Caused Human Fatalities In Yellowstone National Park: Characteristics And Trends, Kerry A. Gunther
Human–Wildlife Interactions
Three fatal bear (Ursus spp.) attacks in Yellowstone National Park (YNP), USA, from 2011 to 2015 were a catalyst for YNP managers to evaluate the circumstances of bear-caused fatalities as well as the bear safety messages it distributes to park visitors. I reviewed records of all fatal bear attacks that occurred in YNP from 1872 to 2018. Seven of the 8 fatalities were caused by grizzly bears (U. arctos horribilis). The per capita risk of being killed by a grizzly bear was 1 fatality for every 26.2 million park visits. Most fatal bear attacks in YNP involved …
Impact Of Covid-19 On Aviation-Wildlife Strikes Across Europe, Isabel C. Metz, Marta Giordano, Dionysios Ntampakis, Marianna Moira, Anneke Hamann, Rosanne Blijleven, Jürgen J. Ebert, Alessandro Montemaggiori
Impact Of Covid-19 On Aviation-Wildlife Strikes Across Europe, Isabel C. Metz, Marta Giordano, Dionysios Ntampakis, Marianna Moira, Anneke Hamann, Rosanne Blijleven, Jürgen J. Ebert, Alessandro Montemaggiori
Human–Wildlife Interactions
Collisions between aircraft and wildlife (i.e., wildlife strikes) pose a serious threat toward the safety of aircraft, its crew, and passengers. The effects of COVID-19 related travel restrictions on wildlife strikes are unknown. With this study, we aim to address this information gap by assessing the changes of wildlife hazard management performance across European airports during the lockdown period (e.g., period of reduced operations and borders closure in spring 2020). We also sought to raise awareness of the importance of wildlife strike prevention in times of reduced operations. The objective of our study was to compare wildlife strike data before …

Trico: A Novel Repellent For Preventing Deer Damage To Ornamental Shrubs, Paul D. Curtis, Brian C. Eshenaur
Human–Wildlife Interactions
Homeowners whose landscape plants are repeatedly browsed by white-tailed deer (Odocoileus virginianus; deer) desire repellent products that are effective and long-lasting. We conducted a 12-week trial from January 6 through April 5, 2021 to test the duration and efficacy of a novel deer repellent (Trico®) relative to Plantskydd®, a commonly used deer repellent, and untreated plants. We placed treated and control Japanese yew shrubs (Taxus media ‘Hicksii’) at 4 homeowner sites (Birch Hills Drive, Fairview Crescent, Pinegrove Ave., and St. Paul Blvd.) near Rochester, New York, USA, where we detected deer presence. Yews are frequently eaten …
Stakeholder Acceptance Of Wild Equid Fertility Control Mirrors Global Shifts In Attitudes To Wildlife Management, Giovanna Massei, Stephanie L. Boyles Griffin
Stakeholder Acceptance Of Wild Equid Fertility Control Mirrors Global Shifts In Attitudes To Wildlife Management, Giovanna Massei, Stephanie L. Boyles Griffin
Human–Wildlife Interactions
Wild equid (horses [Equus ferus] and burros [E. asinus]) populations have increased on public lands in the United States since the passage of the Wild Free-Roaming Horses and Burros Act of 1971. As of March 1, 2022, the Bureau of Land Management (BLM) estimated that wild equid populations on designated herd management areas (HMAs) may exceed 82,000 animals. In 2020, the total population of wild equids in the United States was estimated to exceed 300,000 animals. The BLM sets an appropriate management level (AML) for wild horse and burro herds on each HMA and removes animals …

Human–Wildlife Interactions
As transportation infrastructure expands to accommodate increasing human population growth, wildlife–vehicle conflicts (WVCs) are a growing concern for motorist safety and wildlife populations. In the case of large ungulates, minimal information exists on successful mitigation of WVCs involving bighorn sheep (Ovis canadensis) and habitat fragmentation. Too address this void, we evaluated the effectiveness of 3 new wildlife overpasses, 3 culverts, 2 bridges, and ungulate exclusionary fencing as potential desert bighorn sheep (O. c. nelsoni; sheep) crossing opportunities along US Highway 93 in Arizona, USA. We evaluated sheep movements using global positioning system (GPS) radio-transmitter collars and …
