The study investigated the distribution of tree species, usefulness and perception of farmers on retention of open grown trees (OGTs) on their farmlands in Oyo State. OGTs are tree species located outside the designated forest reserves. Three stage sampling design was adopted in the selection of 80 farmers from Ibadan and Saki zones of Agricultural Development Programme of Oyo State (OYSADEP). Through field observation and questionnaire sampling, information collected were level of awareness of trees on farmlands, retention of trees during land preparation, farm size, type of farming system and tree species growing of farmlands. The result of the descriptive and inferential test statistics indicated that there are variations in farmers’ perceptions towards the usefulness of trees on their farmlands. In Ibadan Zone, 77.5% of farmers do use and collect products from the trees on their farmlands, while 22.5% do not. In Saki zone, 50% of the farmers were aware of the usefulness of trees growing on their farmlands. Chi-square test of statistics revealed that some socio-economic characteristics of the farmers were significant when tested at α0.05, indicating that they do have influence over retention of trees on farmland. Gmelina arborea Roxb and Terminalia superba Engl. and Diels were the most species identified in Ibadan and Shaki agricultural Zones respectively. The existing forest management regimes will be more significant if trees on farm landscape are also put on board by being given a strong support both politically and financially to reduce over burden of illegal removal of trees from the reserves.
