A study was conducted to quickly analyze diversity richness and correlation between different diversity richness at species level (trees, shrubs and herbs). The research exercise was done in the pure chirpine forest of College of Natural Resources campus. The numbers of chirpine trees, shrubs and herbs were recorded in the circular sample plot of size 0.05 ha (radius of 12.62 m). SPSS was used to analyze the data. The species richness was calculated through single factor Analysis of Variance (ANOVA). Correlation of coefficients also analyzed to see if there is association and relationship between the different data variables collected. A total of 2,028 species were recorded from the study area, out of which 56 were chirpine trees, 462 shrubs and 1,510 herbs. The diversity richness on total count of chirpine, shrubs and herbs was significant, F (2, 39) = 36.095, p = .000. It was deduced that chirpine richness was comparatively poor than the shrubs and herbs richness. This means the species richness have significant effect on the biodiversity richness.
