The expansion of urban areas and associated clearing of habitat can have severe consequences for native wildlife. One option for managing wildlife in these situations is to relocate them. While there is a general perception that relocation is humane, transparency of outcomes is lacking. Here, we document the outcome of 122 western grey kangaroos (Macropus fuliginosus) relocated from an urban development site on the edge of Perth, Western Australia. Global Positioning System (GPS) or Very High Frequency (VHF) collars were fitted to 67 kangaroos, and their survival and movement were monitored over 12 months using telemetry, camera traps and spotlighting. Only six collared animals survived for the duration of the study with most dying within a week of the relocation, indicating stress associated with capture as the likely cause. By the completion of the study, 111 kangaroos were predicted to have died based on the proportion of individuals known to have died. Movement patterns of surviving GPS collared kangaroos changed over time from largely exploratory forays, to more repeated movements between focus areas within home ranges. The poor outcome here raises concerns around the viability of relocating a relatively large number of kangaroos as a management option. It also highlights the need for careful planning to limit the stress associated with capture and transport if relocations are to be used for managing kangaroos in urban areas.

从城市开发地点搬迁的西部灰袋鼠（Macropus fuliginosus）的发布后监测

城市面积的扩大以及相关的栖息地清理可能会对本地野生动植物造成严重后果。在这种情况下，管理野生动植物的一种选择是重新安置它们。尽管人们普遍认为搬迁是人道的，但结果缺乏透明度。在这里，我们记录了122种西方灰色袋鼠（Macropus fuliginosus）从西澳大利亚州珀斯边缘的城市发展基地搬迁。将全球定位系统（GPS）或甚高频（VHF）项圈安装到67只袋鼠中，并使用遥测，相机陷阱和聚光灯监测了它们在12个月内的生存和运动。在研究期间，只有六只领颈动物幸存下来，大部分动物在搬迁后一周内死亡，这表明与捕获有关的压力是可能的原因。这项研究完成后，根据已知死亡个体的比例，预计有111只袋鼠死亡。幸存的GPS项圈袋鼠的运动方式随着时间的流逝而发生变化，从很大程度上是探索性的尝试，变为家庭范围内焦点区域之间更多重复的运动。这里糟糕的结果引起了人们对重新安置袋鼠作为管理选择的可行性的担忧。它还强调，如果将搬迁用于管理城市地区的袋鼠，则需要进行周密的计划以限制与捕获和运输相关的压力。
