Gives the dominance and diversity of species.|
|ni= Number of individual in each species|
N= Total number of individuals in that community
C= Dominance index
Reciprocal of dominance index is diversity index
This method is used to compare diversity between different community and habitats. The value of Shannon-Wiener index usually falls between 1.5 and 3.5 and rarely surpass 4.5.
H = Shannon wiener diversity index
|This index shows the equality of abundance.|
|e = Peiben evenness index|
S= number of species
It is a vegetation index that separates green vegetation from the background soil brightness by using satellite data.
The value lies between -1 to 1 [0 and negative values indicate no vegetation].
