  3. a,bValues within columns with the same letter are not significantly different at the 5 % level
  4. cIn woodlots, only dominant Eucalyptus species were counted (the most commonly found were E. camalduleis Dehnh, E. globulus Labill, and E. saligna Sm), hybrid species were excluded since they could not be recognised and differentiated
