\begin{abstract}
\normalsize{
The abundance and species diversity of mesofauna and litter arthropods were surveyed in the natural forest and three plantations (Nauclea diderichii, \textit{Gmelina arborea} and \textit{Tectona grandis} plantations) in Akure Forest Reserve Aponmu, Nigeria to examine the effect of plantation development on both the abundance and species diversity of litter arthropods and mesofauna. Sample Plot (PSP) of 100 × \mbox{100\,m} blocks which were then divided into smaller plots of 20 × \mbox{20\,m} were laid in each habitat. Soil samples where taken from the selected sample plots at four different location randomly selected, to identify mesofauna and microorganisms while litter arthropods caught were preserved and identified. 1165 individuals of mesofauna were encountered (distributed in 23 species) in all the studied habitats. The highest abundance of mesofauna was encountered in \textit{Gmelina arborea} plantation (334 individuals) while Nauclea diderichii plantation has the least abundance of 201 individuals. Natural forest recorded the highest species diversity of mesofauna (23 species) while the least species diversity was found in the \textit{Tectona grandis} plantation. 64 individual of litter arthropods were however encountered in the study area (distributed in 27 species). Natural forest accounts for the highest in both the species diversity and abundance (i.e. 21 individuals and 11 species respectively.) \textit{Tectona grandis} accounts for the least species diversity in the studied habitats (5 species) and \textit{Gmelina arborea} plantation has the least abundance of litter arthropods (12 individuals). There was a significant regression equation in the relationship between the species diversity of mesofauna and litter arthropods ($p < 0.05$). }
