The growing rate of wildlife underpass use for the mitigation of road-induced wildlife mortality necessitates the development of low-cost monitoring tools for determination of mitigation success. Trail cameras are one such tool that can provide valuable insight into the usage patterns and effectiveness of wildlife underpasses. We deployed trail cameras in wildlife underpasses in Guelph, ON, to develop recommendations for camera monitoring protocols. The trail cameras used high interval time lapse and motion sensors from April to October of 2016 to capture crossing by a variety of species through two slotted, small animal underpasses. Daily and seasonal underpass usage patterns of 21 species and species groups suggest that to comprehensively monitor underpass usage, cameras must be active continuously and utilize high frequency time lapse and motion sensors simultaneously to capture crossing events by both endothermic and ectothermic species. Although these recommendations are dependent on the specific objectives and target conservation species, these results can be used to guide a range of underpass monitoring programs.
随着缓解道路诱导野生动物死亡的需要，野生动物地下通道的使用增长率不断提高，这就需要开发低成本的监测工具来确定缓解的效果。巡线摄像机就是这样一种工具，它可以为野生动物地下通道的使用模式和效果提供有价值的见解。我们在安大略省圭尔夫的野生动物地下通道中部署了巡线摄像机，以制定摄像机监测协议的建议。巡线摄像机使用高间隔时间延迟和运动传感器，从 2016 年 4 月到 10 月，拍摄了通过两个有槽的小动物地下通道的各种物种的穿越情况。21 个物种和物种组的日和季节地下通道使用模式表明，为了全面监测地下通道的使用情况，摄像机必须持续运行，并同时利用高频时间延迟和运动传感器，以捕捉温血和冷血物种的穿越事件。虽然这些建议取决于特定的目标和目标保护物种，但这些结果可以用来指导一系列地下通道监测计划。
