The economic prospects of ecosystem services accessed by communities around Girei forest reserve were investigated. This was as a result of over dependence on the forest reserve as a source of livelihood. A stratified random sampling was used to interview 180 household heads on their socio-economic characteristics and the benefits they derived from the forest reserve. Relevant descriptive statistical tools were used to analyze the data. The results showed that most households were headed by males 91.3% while 8.7% of the households were headed by females. The mean annual income of the respondents was ₦267,401. A lot of benefits were obtained from the forest reserve such as honey, firewood, poles, medicines, grass etc. The estimated annual monetary value of ecosystem provisioning services obtained from the forest reserve is ₦25,907,400 per annum. However, due to the enormous benefits derived from the forest reserve and the unsustainable harvest of the forest resources as a source of livelihood, quantitative assessment of the indigenous tree species in Girei forest reserve was also carried out. To achieve these;;the relative frequency, density, relative dominance, and importance value index of tree species in the forest reserve were determined. The tree with the highest dominance Tamarindus indica (39.1) while the least is Prosopis africana (0.54). The importance value index shows that Tamarindus indica (28.67) has the highest value index while the least is Parkia biglobosa (1.90). The result of diversity of the tree species was 1.941 using Shanno’s diversity index which indicates uncertainty of the species in the study area. Therefore, there is need for urgent concerted management and policy actions which are geared towards monitoring the health and integrity of Girei forest reserve such it can continue to generate ecosystem services which are beneficial to the present and future generations.
