Summary:Impact of Macrotermes termitaria as a source of heterogeneity on tree diversity and structure in a under controlled grazing and annual prescribed fire was examined. The estimate of species richness was analyzed graphically using the rarefaction curve. The nonparametric estimator was used to estimate total tree species richness. It was observed that Macrotermes termitaria showed a relative frequency 9% on mounds and 23 and 21% on mound surroundings. Tree density and basal area were increased on mounds as compared to the surrounding soils while the difference in tree species richness generated three different areas. The mean tree density and the mean tree basal area were significantly increased for the burnt subplots in fire versus no fire treatments.
