Effects of site and tree size on wood density and bark properties of Lebombo ironwood (Androstachys johnsonii Prain)

Background: Wood and bark are important renewable natural resources. Density is an property that used to describe wood quality for a number of end uses. However, density, proportion dimensions vary with age site, as well among within trees. The aim this study was investigate the effect diameter class, vertical position stem on density bark, volume, dry-mass thickness Lebombo ironwood (Androstachys johnsonii Prain). Methods: conducted 93 Lemombo trees growing in Mozambique. Eight discs were sampled from each selected tree over under measured. Bark thickness, mass determined along basic disc. Results: overall average whole-stem properties estimated at: 786 kg m–3 586 19% dry-mass, 9 mm thickness. Height level uniquely explained most variation (97%), volume (95%) (86%). Diameter class (51%) (51%). Site only small all dependent variables. Conclusions: Overall, patterns highly stem. differences not significant source studied. Improved knowledge species will aid its sustainable management utilisation.
