Using constructed covers to protect infrared cameras while surveying wildlife along roadways
We examined the effectiveness of simulated underground utility cable markers in hiding infrared cameras along a roadway. Our study took place in the summer of 2014 and winter of 2015 as part of a survey to determine whether swift fox (Vulpes velox) were present along the route of a planned highway expansion project in western Nebraska. Camera covers were constructed of square vinyl posts modified to conceal and camouflage the camera, and used in conjunction with a scent attractant. Camera stations were placed approximately 1.6 km apart and ran for 5 nights along a 200 km stretch of the planned construction site. There were 2,135 trap nights in the study. No camouflaged cameras were taken or disturbed in any way. The only camera placed along the roadway during the survey that was not placed in one of our covers was cable-locked to a utility pole. It was stolen within 3 days. By allowing cameras to remain in the right-of-way (ROW), obtaining access to place the cameras was greatly facilitated in many areas. The cost per camera cover was approximately $20. We conclude this method of disguising cameras is an effective one for roadside use.
