The effects of sylvatic plague and habitat fragmentation present species conservation challenges for prairie dogs (Cynomys spp.) and other wildlife species they support. Active reestablishment of extirpated prairie dog colonies may become increasingly necessary to achieve some conservation goals. We compared a passive‐integrated‐transponder (PIT) tag monitoring system and trail camera photographs to monitor short‐term survival of captive dye‐marked black‐tailed prairie dogs (Cynomys ludovicianus) translocated into artificial burrows. We deployed cameras and a PIT‐tag monitoring system in 2016 and 2017 (Nov–Sep) and collected 1.2 million PIT‐tag scans and >255,000 photographs at a Colorado Parks and Wildlife facility near Fort Collins, Colorado, USA. There was no difference in the daily mean number of prairie dogs detected between the 2 monitoring methods (photographs  = 3.40, PIT tags  = 4.06). However, PIT‐tag scans achieved a population census in 10 days (100% detected, 95% CI = 89–100%); whereas, photographs were able to detect only 67% of the prairie dogs during this same time (95% CI = 50–80%). Trail camera photographs of uniquely dye‐marked individuals may be ideal for short‐term monitoring (≤6 months), while PIT tags are likely to outperform cameras in studies requiring efficient longer term monitoring of permanently marked prairie dogs. Although both monitoring techniques performed well in a semicaptive setting, how these techniques would perform when scaled to larger or more complex settings requires further research. © 2020 The Authors.

两种监测易位草原土拨鼠的方法的比较

森林鼠疫和栖息地破碎化的影响给草原犬（Cynomys spp。）和它们所支持的其他野生生物带来了物种保护方面的挑战。积极重建已灭绝的草原犬鼠群体对于实现某些保护目标可能变得越来越必要。我们比较了被动集成应答器（PIT）标签监控系统和跟踪相机的照片，以监控圈养染料标记的黑尾土拨鼠（Cynomys ludovicianus）换成人工洞穴。我们在2016年和2017年（11月至9月）部署了相机和PIT标签监控系统，并在美国科罗拉多州柯林斯堡附近的Colorado Parks and Wildlife设施中收集了120万个PIT标签扫描和超过255,000张照片。两种监测方法之间检测到的草原土拨鼠日均数没有差异（照片 = 3.40，PIT标签） = 4.06）。但是，PIT标签扫描在10天内完成了人口普查（检测到100％，95％CI = 89-100％）；而在同一时期，照片只能检测到67％的草原土拨鼠（95％CI = 50–80％）。带有独特染料标记的个人的尾部摄像头照片可能是短期监视（≤6个月）的理想选择，而在需要对永久标记的草原犬进行长期有效监视的研究中，PIT标签的性能可能优于照相机。尽管这两种监视技术在半捕获环境中均表现良好，但是当将这些技术扩展到更大或更复杂的环境时，这些技术的性能如何仍需进一步研究。©2020作者。Wiley Periodicals LLC代表野生动物协会发布的《野生动物协会公告》。
