Biodiversity, a multidimensional property of natural ecosystems, is difficult to quantify partly because of the multitude of indices proposed for this purpose. Diversity Indices aim to describe general properties of communities that allow us to compare different regions, taxa, and trophic levels. Therefore, diversity indices play a fundamental role in environmental monitoring and conservation, although there is no consensus about which indices are more appropriate and informative. We normally use common diversity indices of species richness (S), Shannon’s diversity (H’), Simpson’s diversity (D1), Simpson’s dominance (D2), Simpson’s evenness (E) for community analysis. So far, there is no comprehensive phytosociological study on grassland ecosystems of Allahabad area have been undertaken. Using the diversity indices, the objective of the present study was to quantify the grassland community in Allahabad area to generate baseline information on the distribution patterns and composition of the species of grasslands in the District. This will also support long term conservation strategies and species level monitoring of biodiversity in Allahabad. The present effort is to study the grassland diversity in Allahabad area to channelize the conservation strategy for biodiversity of Allahabad.
