Table 1 (a) Statistically significant (p < 0.05) linear correlation between terrain attributes, ALT, mALT, TPI, SD, Sl, North, East and background factors, meanSOC, meanSWC for A dataset. (b) Statistically significant (p < 0.05) linear correlation between terrain attributes, background factors and stability proxies, rankRs, rangeRs in A dataset and in the subgroups (see codes in the text). Regular letters mean scale-independent correlations (valid for DEM1-5), italic underlined letters mean correlations valid for less smooth DEMs (DEM1-2 or 1–3), “pos” and “neg” indicate the sign of the correlation.
