Survey of Wood Species Utilized for Roofing in South- Western Nigeria
Arowosoge O.G.E

A survey of the wood species utilized for house roofing in South Western Nigeria was carried out and a priority class developed for the wood species. Data were generated through the administration of structured questionnaire on 222 respondents randomly selected from Akure, Ado-Ekiti and Ibadan. Data were analysed using descriptive statistics and Friedman chi-square to compare the relationship of ranking pattern in the three cities at 5% probability level. 14, 11 and 16 wood species were listed in Akure, Ado-Ekiti and Ibadan as wood species utilized for roofing, while 21 were compiled from the lists of three cities. The preference for wood species varied among the three cities (χ 2 =75.03, df = 2, P<0.05). Piptadeniastrum africana, Pterygota macrocarpa and Celtis zenkeri were most preferred in Akure, Ado-Ekiti and Ibadan respectively with a rate of 82.12%, 89.11% and 89.91%. With the use of lesser used wood species (LUWS) for house roofing, it becomes imperative that the technical properties of these LUWS be studied and made available to users.
