Inspection of the mean entrance count under each vegetation and imager class (Table 4) revealed that, on average, both imager types and visual inspection detected almost the same number of entrances in open and vegetated areas. In mixed areas the Vayu detected, on average, one more entrance per warren than visual inspection and twice as many entrances per warren than the Zenmuse.
