  1. Units of measurement: total aboveground biomass, kilogram; diameter at breast height, centimeter; total height (ht), meter; basic density, gram per cubic centimeter
  2. AGB total aboveground biomass, dbh diameter at breast height, ht total height, ρ basic density, n sample sizes
  3. a The figure refer to the fixed age of planted mangrove trees which is surrogate to dbh
