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.
