Obeche (Triplochiton scleroxylon K. Schum.): poor products development wood but good environmental tree in Nigeria
Languages of publication
Obeche (Triplochiton scleroxylon K. Schum.) is a tropical large tree whose wood products either in solid or reconstituted forms are extremely vulnerable to concomitant insects attack. Although established as a successful plantation species for veneering and plywood production but noted as a good environmental tree in Nigeria. However, there is very little specific information that substantiates this potential. We report the organisms inducing biodeterioration of Obeche wood products under service and describe the characteristics of Obeche trees under environmental service between 2012 and 2016. All the 47 Obeche wood-based products (OWBPs) studied, comprising 12 beehives, 10 food canteen stalls, 10 office tables, 10 laboratory cabinets and 5 office walls were economically and dominantly co-infested by beetles and termites. Interestingly, during the four-year observation period, all the 8 life Obeche trees encountered were found to exhibit high stability with excellent resistance to hollowness and other degradative pests, even at around 2 m Diameter at Breast Height (DBH), reflecting its robust biophysical protective barrier mechanisms. Additionally, there were observations of enhanced coexistence with other tree species, including shrubs and grasses indicating a tolerance potential role at improving the relative contributions of several species (plants community) to ameliorate tropical environments.
