This study, we assessed the natural durability of seven tropical species using the European standard EN 807 (2001). We embedded samples of <em>Dalbergia granadillo</em>, <em>Cordia elaeagnoides</em>, <em>Swietenia humillis, Tabebuia donell-smithii</em>, <em>Hura polyandra</em>, <em>Enterolobium cyclocarpum</em> and <em>Tabebuia rosea </em>and temperate species <em>Fagus sylvatica</em> (as a control) in sandy, clay-sandy-loam and clay-loam for 8, 16, 24 and 32 weeks. We evaluated durability of the samples by determining the mass loss and modulus of elasticity (MOE) loss. The results varied significantly (p &lt; 0.001) depending on timber species and soil type considered. The <em>D. granadillo </em>and<em> C. elaeagnoides</em> were the most durable, with mass losses of 4.5%, 6.5% and MOE losses of 4.5%, 20.5%, respectively<em>.</em> <em>F. sylvatica, T. rosea </em>and <em>E. cyclocarpum </em>samples were the least durable, with mass losses of 22.3-25% and MOE losses of 35.8-59.8%, respectively. Decay was most aggressive in sandy-clay-loam soil followed by the clay-loam soil and finally the sandy soil.</p> ER -
