  1. Frequency: no. of plots in which a species occurs/total no. of plots × 100.
  2. Relative density (RD): no. of individual of a species/total no. of individual of all species × 100.
  3. Relative frequency (RF): frequency of a species/total frequency of all species × 100.
  4. Relative dominance (RDom): total basal area of a species/basal area of all species × 100.
  5. Importance value index: IVI = RD + RF + RDom.
