Tree yield and regeneration potential were investigated in natural forest ecosystem in the southwestern region of Nigeria. Three forest reserves were selected for data collection. The three forest reserves are Akure Forest Reserve in Akure South Local Government Area, Eda Forest Reserve in Ekiti State and Idanre Forest Reserve in Idanre Local Government Area of Ondo State. Four equal size (25 × 25m) sample plots were centrally located in each of the selected forest reserves by adopting systematic line transect method. All trees with Dbh greater than or equal to 10cm encountered in each of the plots were identified. Quadrants of 5 × 5m size were laid inside the 25 × 25m plots that were laid. Akure forest reserve had the highest volume per hectare (172.96m3), this was followed by Eda forest reserve (136.52m3) and Idanre forest reserve (111.88m3). Idanre forest had the highest regeneration potential (2.49%), followed by Akure forest reserve (2.38%) then Eda forest reserve (1.56%). A Regeneration potential of 2.14 was obtained when the forest were pooled together. It was concluded that the forest should continued to be managed and preserved from biotic and abiotic factors that could hinder regeneration in the natural forest ecosystem. This will help conserve biodiversity and provide all the other services required in perpetuity.
