First, Venter et al. ([4]) visually overlay the 2009 human footprint (HFP) "no pressure" areas (Venter et al., [5]) with HM zero values and notes high incongruence. Areas are in blue where HFP = 0 and HM /= 0; yellow where HM = 0 and HFP /= 0; and red where HFP = 0 and (i) HM = 0; (ii) HM <= 0.0018 (the median value in HFP = 0), (iii) HM <= 0.10 (the median HM value globally and threshold used for "low modified" lands in Kennedy et al., [2]). Despite differences in the spatial distributions between HM and HFP maps at finer scales (Figure map insets), the correlation of land modification patterns remain fairly similar at coarse scales (Kennedy et al., [2]).
