Assessments of rock art degradation in Maros-Pangkep. (a) Summary of damage assessments in 2003–2005 for 727 hand stencils in 36 cave sites⁷. (b) Damage ratings assigned to 44 sites in 2013 using broader criteria¹¹ (see Methods). Coloured numbers indicate the percentage of sites in each damage category. (c) Comparison of the two sets of assessments for 21 rock art sites in common (numbers identify sites noted in Supplementary Table 1). The damage ratings in (b) have been assigned broad percentage ratings: “good” (< 30% damaged), “moderate” (30–70% damaged), “poor” (> 70% damaged). Both datasets show that the degree of rock art degradation is highly variable among sites.
