\textbf{Abstract}
\begin{abstract}
\normalsize{
This research investigated land use and ecological benefits of tree species diversity in two selected communities of Kogi State. Application of Geographical Information System (GIS) and Remote Sensing (RS) techniques was use for the extraction of land use data and parameter of these communities in Kogi State. All trees with diameter at breast height (dbh) greater than or equal to \mbox{10\,cm} were identified, dbh measured and their frequencies taken in all the area enumerated within the selected communities. There were 811 stems in these communities which belong to 94 tree species and 33 families. The Shannon-Wiener diversity index (3.08 and 3.24), species evenness (0.50 and 0.61) and other biodiversity indices were employed to determine the tree species diversity of the communities. Tree species with high relative density include: Magnifera indica, Greenwayodendron suavolens, \textit{Gmelina arborea}, and \textit{Parkia biglobosa}, Species with high relative dominance include: Delonix regia, \textit{Parkia biglobosa}, and Magnifera indica while species with high Importance Value Index include: Delonix regia, Magnifera indica and \textit{Gmelina arborea}. In addition, the total basal area and volume of 10.97m$^{2}$ and 99.57m$^{3}$ for kabba and Okebukun 8.13m$^{2}$ and 63.66m$^{3}$. The biodiversity indices indicated the tree species diversity of these community and Geographical Information System (GIS) and Remote Sensing (RS) showed adequately the level of land use changes and vegetation cover in Kabba and Okebukun communities in Kogi State. This study provides the baseline information in relation to tree species diversity and land use of these community and adequate management of the tree species of these communities.}
