Gambari Forest Reserve (GFR) is located in Oyo State, in the south-western region of Nigeria, in the Mamu locality (Gambari Forest), co-ordinate 3.7 and 3.9E” and latitude 7°26 1 N and longitude 3°5 1 E. i.e. 17 km South-East of Ibadan, along the Ibadan/Ijebu-Ode road. The major taxa studies for this research include the forest tree species forest ecosystem in Gambari Forest Reserve, such as: Leucaena leucocephala, Leucaena glauca, Gliricidia sepium,Tectona grandis, Gmelina arborea, Swietenia macrophylla, Acacia spp., Albizia spp., Cassia siamea, and Pithecellobium saman. 200 key respondents participated in this study, which were drawn from the seven main communities namely Ibusogboro, Oloowa, Daley North and south, Onipe, Mamu, Olubi and Onipanu respectively. The results revealed that there are significant anthropogenic interventions taking place in the study area. It is therefore imperative to conserve and safeguard GFR ecosystem resources, as ensuring that ecosystem services and biodiversity function at optimum levels. This study therefore recommends continued research to be undertaken, in addition to consistent monitoring and conserving our fragile forest resources, with the aim of achieving optimum functioning and service delivery.
