Item Evaluation of the Contributions of Vitellaria Paradoxa C. F. Gaertn and Parkia Biglobosa (Jacq.) Benth to Rural Livelihood in Oyo State, Nigeria(2012) Jimoh, S .O; Asinwa, I. O.Upsurge in population has resulted in pressure on many tree species including Vitellaria paradoxa C.F.Gaertn.and Parkia biglobosa (Jacq.) Benth. These species are highly valued for their socio economic potentials. The study therefore assessed the contribution of V. paradoxa and P. biglobosa to rural livelihood in Oyo State, Nigeria with a view to generating information on the socio-economic values of the species to the rural communities. Stratified sampling technique was used to divide the study area into three based on ecological zones where twenty percent of each ecological zone was selected. A multistage sampling procedure was employed in collecting data on socio-economic importance of the two species using structured questionnaire. Data collected were analyzed using descriptive statistics, cross tabulation and chi-square. The result of chi-square analysis revealed that degree of contributions of the species to daily income of processors, marketers and harvesters were significant (P < 0.05) in dry woodland and moist woodland but not significant in the rainforest zone. The degree of contribution of V. paradoxa to household food consumption was not significant in moist woodland and rainforest but significant in dry woodland (P < 0.05). It is recommended that domestication and plantation establishment of the two species should be encouraged by the forestry stakeholders in order to sustain the contribution of the species to the livelihoods of rural householdItem Densities and Distribution of Vitellariaparadoxa C.F.Gaertn. and Parkia biglobosa (Jacq.) R.Br.ex G.Don. in Agro-ecosystems in Oyo State, Nigeria(Ecological Society of Nigeria, 2012) Jimoh, S .O.; Asinwa, I. O.Population increase has led to increased pressures on many socioeconomically and ecologically important tree species including Vitellaria paradoxa C.F.Gaertn.and Parkia biglobosa (Jacq.) R.Br.ex G.Don. This portends great threats to the continued existence of such species including the myriads of goods and services they provide. There is need to put on record, scientific evidence of the current status of these species in order to draw attention to the pressures on their populations and the need for deliberate actions for their conservation and sustainable management. We assessed densities and distribution of Vitellaria paradoxa and Parkia biglobosa in some agro ecosystems in Oyo State, Nigeria with a view to generating information on the current stocking of the species in the various ecosystems and provide base line data for subsequent resource monitoring and sustainable management planning. Oyo State was stratified into three agro-ecological zones viz: dry-woodland/Southem Guinea savanna, moist-woodland/derived savanna and rainforest. A multistage sampling procedure was used in collecting data on densities and distribution of Vitellaria paradoxa and Parkia biglobosa in the agro ecosystems through field survey. Descriptive statistics, cross tabulation, simple t-test and analysis of variance (ANOVA) were used to analyze the data. Student’s t-test and analysis of variance indicate that there was no significant difference at 5% level of probability in the densities of V paradoxa and P. biglobosa in the cultivated and fallow land. Potential mother trees for regeneration were found mainly on crop farms while younger trees dominate the fallow plots. This is an indication of extraction of older trees on fallow plots apparently for domestic energy supplies. It is recommended that the management of V. paradoxa and P. biglobosa should be intensified through enrichment planting and deliberate cultivation in plantations in order to meet the high demand pressures on their populations
