1. Calculate the aboveground biomass (AGB) in tons of carbon per hectare (t C/ha)

2. Estimate the belowground biomass (BGB) in tons of carbon per hectare (t C/ha)

3. Derive the total live tree t C/ha for each plot, by combining BGB and AGB estimates

4. Calculate the mean value of the t C/ha for the four plots and find the standard deviation and confidence interval at 95%

If sampling is conducted at an appropriate scale, the average total live tree t C/ha could contribute to the development of an emission factor (EF) for the stratum

4 Steps to derive the emission factor:

2. Estimating Emissions from Degradation by Logging

Estimating the total C emissions and CO2 emissions from selective logging, with use of the following formula:

𝐶𝑒𝑚𝑖𝑠𝑠𝑖𝑜𝑛𝑠 (𝑡𝐶 / 𝑦𝑟 )= [𝑣𝑜𝑙∗ 𝐸𝐿𝐸∗ (1−𝐿𝑇𝑃 ) ]+ [𝑣𝑜𝑙∗𝐿𝐷𝐹 ]+ [𝑣𝑜𝑙∗ 𝐿𝐼𝐹 ]

Vol = Total volume of timber extracted through selective logging activities

per year

ELE = Extracted Log Emissions (t C/m3)

LTP = Proportion of log carbon going into Long Term Wood Products (%)

LDF = Logging Damage Factor (t C/m3)

LIF = Logging Infrastructure Factor (t C/m3)

multiply by 44/12
