30. The promoter must estimate the initial quantity of living below-ground biomass using data from the initial inventory of living aerial biomass and the equations in Table 7 below. The promoter must enter this information and data into the CBM-CFS software.
Table 7 – Information used to estimate living below-ground biomass during the initial inventory
| Variable | Method used to estimate the initial quantity of biomass |
| Tree roots | Calculation |
| Softwoods: Root biomass = 0.222 × tree biomass obtained following compilation of the initial inventory | |
| Hardwoods: Root carbon biomass = 1.576 + 0.615 × tree biomass obtained following compilation of the initial inventory | |
| Shrub roots | Calculation |
| Shrubs: root biomass =1.5750 + 0.615 × shrub biomass obtained following compilation of the initial inventory | |
| Grass roots | Default value for 100% cover |
| 15.0 tonnes biomass/ha | |
| To be multiplied by the actual herbaceous cover (ha) obtained during the initial inventory |
