Socio-Economic Benefits of Iroko Trees (Milicia excelsa Welw C.C. Berg) in Ibadan Metropolis, Oyo State, Nigeria

摘要

A complete survey of Iroko trees in Ibadan metropolis was carried out with the view to determining their distribution and status. The entire of Ibadan City was considered for the study. The city was divided into sections and a reconnaissance survey was conducted to confirm existence of the tree species within each of the section. Direct observation of the already identified Iroko trees was then carried out during the actual data collection stage of the study. Permissions were sought before data collection was carried out on the identified trees. A total of 62 Iroko trees were surveyed; out of these, 33 (53.2%) stands were accessible while the remaining 29 stands (46.8%) were inaccessible. Many of the trees that could not be accessed were a result of restriction into the location where they exist. The most frequently observed benefit obtained trees are shade from direct sunlight and cool breeze it creates. Other uses of trees include peeling of the tree bark and used in preparation of local medicine, fetish activities on and around the tree, and use of the fallen branches as firewood. There is urgent need for appropriate protection strategies of these remaining indigenous tree species where they exist.
