WebbShannon–Weiner’s diversity index was used to quantify species diversity status in all the habitats . The index assumes that individuals are randomly sampled from an ‘infinitely large’ population and all the species from a community are included in the sample. Webbdiversity index is the Shannon-Weiner index [5] H =−PilnPi Where H = Shannon-Weiner index, Pi = N ni, ni = Number of individuals of a species, N =Total individuals of all species The diversity index criteria are as follows: H’ ≤ 1 = Low diversity 1 < H’≤ 3 = Moderate diversity H ’≥ 3 = high diversity 2.2.

WebbThough the results of the Shannon-Wiener index needs to be used with caution, it still provides a good learning tool for comparing two distinct habitats. It combines two quantifiable measures: the species richness (# species within the community) and species equitability (how even are the numbers of individual species).
