Between species and wood type variations in some physical,termite resistivity and microstructural properties of some logging residues of Pterygota macrocarpa and Terminalia superba

Abstract

The possible utilization of logging residues (stem off-cuts and branchwood) of Terminalia superba and Pterygota macrocarpa were assessed by comparing their density, termite resistivity (durability) and microstructural tissue proportions. ISO 3131, EN 252-1989, and IAWA protocols were used. Termite resistivity of the residues at same mc were not significantly different (95% confidence level), and were equivalent to their extracted stemwood reported in literature. Thus, for termite resistivity requirements, the logging residues could supplement their extracted stemwood. Density influenced termite resistivity of wood (P < 0.05). Almost all microstructural tissues influenced density and termite resistivity status of the residues. Hence, differentials in microstructural tissue composition rather than mc influence termite resistivity of wood. I recommend establishment of cottage industries in forest catchment areas to extract and process branchwood and off-cuts for use to create employment, curb deforestation towards mitigating climate change.
