Effects of site productivity on individual tree maximum basal area growth rates of Eucalyptus pilularis in subtropical Australia

Abstract Inventory data were available from 96 plots of even-aged, monoculture, tall-open forests Eucalyptus pilularis Smith, aged 2–63 years, growing in sub-tropical regions along the east coast Australia. A model was developed relating maximum possible stem basal area growth rate individual trees to their area. For any tree size, this increased as site productivity increased. However, size at which occurred decreased Much research has shown that, stand age, a particular are taller on more productive sites than less ones. Taller incur greater respiratory costs ensure maintenance photosynthetic capacity canopies; reduces rates. It concluded that with larger areas will have site, whilst smaller site. The may constitute first stage complete system predict wood yields these forests.
