Table 2

The list of equations used for calculating phytosociological characters of the vegetation.

Phytosociological attributes	Formula	References
Basal area (m^2/ha) (BA)		[28, 29]
Frequency, (F%)		[29]
Relative frequency (RF%)		[30, 31]
Density (D)		[29]
Relative density (RD%)		[30, 31]
Abundance, A		[29]
Relative dominance (RD0%)		[28]
Diameter at breast height (cm)		[32]
Important value index (IVI)	IVI = RD + RF + RD0	[26, 29]

Here, a = Total number of individual species in all quadrates, b = Total number of quadrates of studied, c = Total number of quadrates in which the species occurs, n = Total number of individuals of the species; Fi = Frequency of one species; GBH = Girth at breast height.
