  1. Statistical test based on Friedman’s non-parametric two-way analysis of variance (K = 3) with a posteriori tests between the buffer zones. Values of change (%) in each buffer zone in each forest vegetation zone and number of RFPAs in each vegetation zone presented in Table 1. Bonferroni adjusted significance level (P = 0.017) in the pairwise comparisons
