  1. Different letters show significant differences (ab ≠ a, b) by the Mann–Whitney U test (p < 0.05). H(p): Kruskall–Wallis statistic and associated probability. PF  primary unharvested forests, AR  aggregated retention, DRI  dispersed retention under the influence of AR, DR  dispersed retention without influence of AR
