  1. Words in italic indicate the plantation type
  2. Value within the parenthesis indicate the standard error and percentage error
  3. The age of plantations and agroforestry system varied from 5 to 45 years which explained the large standard and percentage errors obtained from their plots data. The minimum (min.) and maximum (max.), the mean biomass density and its stand error (SE), the percent error and the total biomass at each LULC type/LUCa were illustrated
