\( \mathrm{UVDs}=\sum \limits_{i=1}^S UVi\ln UVi=5.155 \)
  1. UVDs use value diversity, UVs a simple sum of all known use for each species, UVi the relative use value of species i, lnUVi the natural logarithm of the relative use value of species i, Abs(lnUVi) the absolute value of lnUVi, S the total number of medicinal plant species in the entire dataset
  2. aOnly species with total use value of all known use categories > 26 are indicated (S = 266, use categories = 14)
