Table 3

The list of equations used for calculating biodiversity indices of the vegetation in the study area.

Biodiversity indices	Formula	References
Shannon–Wiener’s index (H′)		[33, 34]
Margalef’s index (R)		[35]
Simpson’s index (D)		[36]
Pielou’s evenness index (E)		[37]
Menhinik’s index	Db = S/√N	[38]
Similarity index	Jaccard index = j/(a + b + c − j); Sorensen index = 2S/(A + B + C)	[39, 40]

Here; Pi = Pi is the proportion (n/N) of individuals of one particular species found (n) divided by the total number of individuals found (N); S = numbers of species encountered, n = the total number of individuals of a particular species, N = the total number of individuals of all species, j/S = the number of species common among the three sites, a/A = the number of species in site-1, b/B = The number of species in site-2, c/C = the number of species in site-3.
