The relationship between construction materials used and longevity of traditional houses in three parishes adjacent to Kibale National Park in western Uganda was explored. Based on (i) resistance to termite attack, (ii) resistance to insect borers, (iii) rot resistance, (iv) wood that splits well, (v) the wood fibre not entangled, (vi) easy workability, (vii) weight, (viii) straight poles, (ix) availability within 2 km radius and (x) durability, 67 species were recorded, of which 43 are trees, nine climbers, ten shrubs and five herbs. Durable wood resistant to fungal attack, termites and woodborers is preferred in addition to being hard, straight and easy to work with a machete. Ranked high among the wild species are Harrisonia abyssinica Oliver, Millettia dura Dunn., Blighia unijugata Baker and Aegelopsis eggelingii M. R. F. Taylor. The commonly extracted pole sizes are between 5 and 12 cm dbh. Preferred wild ropes to fasten wattle, that are resistant to termites, include Cryptolepis sanguinoleta R. Br., Motandra sp., Urera trinervis (Hochst.) Friis & Imm., Paullinia pinnata L. and Cissus rotundifolia (Forssk.) Vahl. Longevity of houses greatly depended on the wall finishing by plastering with sand/wood ash and cow dung as well as the thatch material used: with the average life span of 14.7 years for grass‐thatched, 20 years for papyrus and 29.9 years for iron‐roofed houses.
