Shed antler hunting (i.e., collecting cast cervid antlers) has increased in popularity during the past decade, but little is known about how this recreational activity affects ungulate movements and space use. We placed geographic positioning system (GPS)‐collars on 133 female and male bighorn sheep (Ovis canadensis), bison (Bison bison), and mule deer (Odocoileus hemionus) to quantify their movements and space use during shed antler hunts compared with those behaviors during helicopter surveys in Utah, USA, from 2012 to 2015. For each species, we calculated means and 95% confidence intervals for distance moved during 90‐minute segments (16 points/day) pre‐event (control, 7 consecutive days prior to event), event (1–2 days), and post‐event (7 consecutive days after event) for shed antler hunts and helicopter surveys. We also compared use of space for each species during these events. Female bighorn sheep did not increase distance moved or substantially change space use during shed antler hunts and helicopter surveys. Male bighorn sheep increased distance moved 41% on average during shed antler hunts and by 2.02 times during helicopter surveys but did not change space use during those events. Female bison increased distance moved 15% on average during shed antler hunts and 30% during helicopter surveys. Mule deer increased distance moved and altered space use the most during shed antler hunts; females increased distance moved 97%, and 54% of females moved a mean distance of 742 ± 642 (SD) m (range = 9–3,778 m) outside of their home ranges during those hunts for a mean of 9.2 ± 9.4 hours (range = 1.5 to 41 hr). Male mule deer increased distance moved by 2.10 times on average during shed antler hunts, and 82% of males moved a mean distance of 1,264 ± 732 m (range = 131–3,637 m) outside of their home ranges during those hunts for a mean of 12.6 ± 7.6 hours (range = 4.5–33 hr). Our results provide timely information about how legal shed antler hunting affects movements and space use of female and male ungulates, especially mule deer, and can guide the conservation of ungulate populations and their habitat. © 2021 The Wildlife Society.

棚鹿角狩猎和直升机测量对不规则运动和空间使用的影响比较

在过去的十年中，流浪的鹿角狩猎（即收集鹿角的鹿角）越来越流行，但是人们对这种娱乐活动如何影响有蹄类动物的运动和空间利用知之甚少。我们在133只雌性和雄性大角羊（Ovis canadensis），野牛（Bison bison）和m子（Odocoileus hemionus）上放置了地理定位系统（GPS）项圈）以量化它们在棚角狩猎期间的运动和空间使用情况，并与2012年至2015年在美国犹他州进行的直升机调查中的行为进行比较。对于每种物种，我们计算了90分钟内移动距离的平均值和95％置信区间（事件前（对照，事件前连续7天），事件（事件1-2天）和事件后（事件后连续7天）每天16点，用于棚角狩猎和直升机调查。我们还比较了这些事件期间每个物种的空间使用情况。在大棚鹿角狩猎和直升机调查期间，雌性大角野绵羊没有增加移动距离或实质上没有改变空间利用。雄性大角羊在猎鹿角时平均距离增加了41％，在直升飞机调查中增加了2.02倍，但在这些事件中并没有改变空间的使用。野牛狩猎时，雌性野牛的移动距离平均增加15％，直升飞机调查期间平均移动30％。鹿在狩猎鹿角时增加了移动距离，并改变了空间使用；女性狩猎距离增加了97％，而54％的女性在狩猎期间平均移动了742±642（SD）m（范围为9–3,778 m），平均距离为9.2±9.4小时（范围） = 1.5至41小时）。猎鹿角时，m鹿的平均移动距离增加了2.10倍，而在搜寻过程中，平均有82％的公鹿平均距离移动了1,264±732 m（范围= 131–3,637 m）。 12.6±7.6小时（范围= 4.5–33小时）。我们的研究结果提供了有关合法鹿角狩猎如何影响雌性和雄性有蹄类动物，尤其是m鹿的运动和空间利用的及时信息。并可以指导有蹄类种群及其栖息地的保护。©2021野生动物协会。
