METHODS FOR ESTIMATING BIOMASS


BIOMASS DENSITY BASED ON EXISTING VOLUME DATA

This method is utilized when there is a defined volume per data and is used primarily for closed biomes.
 The Equation is:
Aboveground biomass density (t/ha) = VOB * WD * BEF
where:
WD = volume-weighted average wood density (1 of oven-dry biomass per m3 green volume)
BEF = biomass expansion factor (ratio of aboveground oven-dry biomass of trees to oven-dry biomass of inventoried volume)

 BIOMASS DENSITY BASED ON STAND TABLES
In this method different tables with regression equations to estimate the biomass density.
