Dynamics Of Tree Diversity In Undisturbed And Logged Subtropical Rainforest In Australia, R Geoff B. Smith, J Doland Nichols, Jerome K. Vanclay

Professor Jerome K Vanclay

In subtropical rainforest in eastern Australia, changes in the diversity of trees were compared under natural conditions and eight silvicultural regimes over 35 years. In the treated plots basal area remaining after logging ranged from 12 to 58 m2 per ha. In three control plots richness differed little over this period. In the eight treated plots richness per plot generally declined after intervention and then gradually increased to greater than original diversity. After logging there was a reduction in richness per plot and an increase in species richness per stem in all but the lightest selective treatments. The change in …
