Index  Formula  Description 
ShannonWiener Diversity (H’)  ${{\displaystyle \sum}}^{\text{}}Pi\mathrm{ln}\left(pi\right)$  Pi is the proportion of S made up of the i^{th} species, and ln is natural logarithm. 
Density (Di)  $\frac{{N}_{A}}{T{A}_{sampled}}$  N_{A} is the number of species “A”; TA_{sampled} is total area sampled. 
Relative Density (RD)  $\frac{RD}{TD}\times 100$  RD is the relative density of species; AD: is the absolute density of species (per 100 m^{2}) and TD is the total density of flora species (per 100 m^{2}). 
Frequency (F)  $\frac{N{P}_{a}}{T{P}_{sampled}}$  NP_{a} is the number of plots in which species “A” occurs; and TP_{sampled} is total plots sampled. 
Relative Frequency (RF)  $\frac{AF}{TF}\times 100$  RF is relative frequency of species; AF: is the absolute frequency of the species, and TF is the sum of absolute frequencies of all species. 
Cover (Ci)  $\frac{\pi \ast {\left(DBH\right)}^{2}}{4000}$  DBH is diameter at breast height (1.3 m); π 3.14. 
Relative Cover (RCi)  $\frac{ACi}{TCi}\times 100$  RC is the relative cover of species; AC is an absolute cover (or basal area) of species i, and TDi_{ }is a total cover (or basal area) of all species. 
Family Importance Value Index (FIVI)  $\frac{RD+RF+RCi}{3}$ 

AboveGround Biomass (AGB)  $WD\ast \left(EXP\left(1.4229+2.148\left(\mathrm{ln}\left[DBH\right]\right)+0.207{\left(\mathrm{ln}\left[DBH\right]\right)}^{2}0.0281{\left(\mathrm{ln}\left[DBH\right]\right)}^{3}\right)\right)$ where: WD is the wood density (0.6)  
BelowGround Biomass (BGB)  $EXP\left(1.0587+0.8836\ast \left(\mathrm{ln}\left[AGB\right]\right)\right)$  
Total Biomass (TB)  $AGB+BGB+DWB$  DWB is deadwood biomass 
Total Carbon (TC)  $0.5\times TB$  (IPCC, 2003) 
CO_{2}e  $TC\times {M}_{W}\left({\text{CO}}_{\text{2}}\right)$  TC is the total carbon; M_{W} is the molecular weight of Carbon (IV) oxide (44/12).
