ABSTRACT Non-lethal management methods for urban coyotes are limited despite an increase in human-coyote conflicts in North American cities. Deterrent devices are recommended to reduce human-coyote conflict; however, no scientific studies have assessed the efficacy of deterrents with urban coyotes. This article investigated the short-term efficacy of motion-activated sprinklers for deterring urban coyotes from residential areas in the Metro Vancouver Regional District of British Columbia. Camera traps were used to monitor coyote activity over three consecutive phases: pre-deterrent, deterrent, and post-deterrent. Sprinklers significantly reduced the daily mean number of coyote visits during the deterrent phase compared to the pre-deterrent phase. There were no significant differences in the daily mean number of coyote visits between the pre-deterrent and post-deterrent phases, however mean duration of visits significantly decreased. This article offers evidence that sprinklers may reduce the presence of coyotes in residential areas, thereby encouraging future research into the development and implementation of humane deterrents for urban coyotes.

运动激活喷水器作为城市土狼人道威慑的功效

摘要 尽管北美城市的人与土狼冲突增加，但城市土狼的非致命管理方法是有限的。建议使用威慑装置来减少人与郊狼的冲突；然而，没有科学研究评估过城市土狼的威慑效果。本文调查了不列颠哥伦比亚省大温哥华地区住宅区的运动激活喷水器在阻止城市土狼进入的短期效果。相机陷阱用于监测三个连续阶段的土狼活动：威慑前、威慑和威慑后。与威慑前阶段相比，洒水装置在威慑阶段显着减少了土狼的每日平均访问次数。威慑前和威慑后阶段的土狼每日平均访问次数没有显着差异，但平均访问持续时间显着减少。本文提供的证据表明，洒水装置可以减少住宅区土狼的存在，从而鼓励未来对城市土狼人道威慑的开发和实施进行研究。
