AN ASSESSMENT OF THE DEMAND AND SUPPLY OF Mansonia altissima IN IBADAN, NIGERIA

Abstract

This study examines the demand and supply of Mansonia altissima sawn wood in Bodija Timber Market, Ibadan, to assess their implications for species conservation. Mansonia altissima, a valuable tropical hardwood, faces overexploitation due to rising demand and limited regeneration. Data were collected from 200 timber marketers using questionnaires and field surveys. Descriptive and inferential statistics, including Pearson correlation and paired sample t-tests, were used to analyze the relationship between supply and demand. Results showed a strong positive correlation (r = 0.980, p < 0.01), indicating that limited supply directly affects sales. Major marketing challenges identified include lack of capital, limited stock availability, transportation difficulties, and weak institutional support. Although market associations assist traders through price regulation, information sharing, and legal aid, problems like inadequate storage, competition, and regulatory pressure persist. The study concludes that unsustainable exploitation threatens Mansonia altissima populations. It recommends improved credit facilities, better market infrastructure, and strict enforcement of sustainable forest management policies to balance commercial needs with long-term species conservation.
