ABSTRACT
The over-dependence on the primary timber species has resulted in increased focus on research in the Lesser Used Species (LUS). Cleistopholis patens is an LUS commonly found in Sierra Leone and Ghana, yet it is commercially underutilized. This study assessed some physical, mechanical, and natural durability of C. patens against termites in comparison with other known commercial species. Three C. patens trees, collected from Assin Akropong Forest Reserve near Assin Fosu in the Central Region of Ghana were used for the study. Moisture content along the stem ranged from 12.38 - 13.81 % from butt to top. The basic density Values showed that C. patens is a low-density
species with a range of 198.7 – 273.2 Kg/m3 from top to butt along the stem. The mean Modulus of Rupture, Modulus of Elasticity, Compression parallel to grain and shear parallel to the grain along the stem (from top to butt) were, 44.58 - 53.92 Nmm-2, 7268 - 8200 Nmm-2, 22.76 - 28.87 Nmm-2 and 5.508 - 7.678 Nmm-2, respectively. The mechanical strength properties values suggest that C. patens generally has a low strength for the butt portion and very low strength for the top and middle portions. The mean natural durability (i.e. mass loss) for the various sections along the stem ranged from 87.75 to 100 % (from butt to top) suggesting that C. patens is a non durable timber. Generally, the mean values for the butt portion was significantly different (P
