Studies on tree population dynamics, growth, mortality and regeneration in a fire treated derived savanna in southwestern Nigeria. This paper assesses the impactof fire on tree species diversity, mortality, growth dn regeneration at Olokemeji Forest Reserve, southwestern Nigeria. There was a decrease in number of species and density of tree populations with burning. Burning exercises a selective influence whereby fire-sensitive species were eliminated. Complete fire protection encourages densification of woodland while burning promotes grassland production. Tree mortality increases with burning. However, mortality was independent of girth class. There were more seedlings, saplings and poles in the protected plot than in the burnt plots.
