Abstract
The significance of medicinal plants to rural livelihood in the provision of affordable health care as well as management and conservation of these resources cannot be overemphasized. In spite of the income being generated from medicinal plant collection many plant parts such as roots or bark used as medicinal materials are destructively extracted. A study was carried out in Olokemeji Forest Reserve, Ogun state to identify the existing medicinal plant species, their uses and contribution to the socio-economic development of the collectors as well as to explore conservation efforts of the respondents. One hundred copies of questionnaire were purposively administered to elicit information on the conservation efforts of medicinal plant collectors. Data were subjected to inferential statistics. Fifteen medicinal plant species which were frequently harvested from the study area according to the respondents include; Alstonia boonei, Rauvolfia vomitoria, Newbouldia laevis, Kigelia Africana, Senna siamea, Anogeissus leiocarpus, Celtis zenkeri, Albizia lebbeck, Abrus precatorius, Azadirachta indica, Khaya ivorensis, Trichilia emetica, Olax subscorpioidea, Gmelina arborea and Hildegradia barteri. These plants were used to cure various diseases (migraine, malaria, convulsion, jaundice, hemorrhoids among others). Alstonia boonei was the most valued species in terms of the amount the respondents were willing to pay for conservation with 10.4% of the total valuation. The Chi-square (p<0.01) result showed relationship between socio-economic variables and willingness to pay for conservation. The significant variables were age, gender, marital status, religion, occupation, major income and minor income.
