Table I
Mean abundance and species richness per log for various arthropod taxa for 5-year-old rehabilitation, 15-year-old rehabilitation and unmined forest (UF). Data are pooled across the three sampling periods. Numbers in brackets are standard errors. For taxa displaying significant differences (in bold), numbers with the same letter are not significantly different at p = 0.05.
