Criterion 5 – Maintenance <strong>of</strong> forest contribution to global carbon cycles<br />
Biomass <strong>and</strong> carbon<br />

MIG indicator 5.1.a: Total forest ecosystem biomass <strong>and</strong> carbon pool, <strong>and</strong> if appropriate, by forest type, age class, <strong>and</strong> successional<br />
stages (UNE, LNE, Eden Southern regions)<br />
Approximately 3 440 000 tonnes <strong>of</strong> CO2e sequestered is estimated to be sequestered in Forests<br />
NSW hardwood <strong>and</strong> s<strong>of</strong>twood plantation (refer to figure 2-5A).<br />
Forests NSW estimates the amount <strong>of</strong> CO2e sequestered in its planted forest estate. This includes<br />
both s<strong>of</strong>twood <strong>and</strong> hardwood plantation. The assumptions for the CO2e sequestration calculations are<br />
shown in table 2-5A.<br />
The total amount <strong>of</strong> CO2 sequestered in Forests NSW total native forest was estimated to be<br />
3.6 megatonnes <strong>of</strong> CO2 during <strong>2007</strong>–<strong>2008</strong>. For more details on the basis for this estimate see the<br />
Forests NSW Annual report <strong>2008</strong>–2009 (Forests NSW, Pennant Hills NSW).<br />
Table 2-5A: Assumptions for carbon sequestration in Forests NSW planted forest estate<br />
Assumptions<br />
CO2 sequestered (tonnes CO2e) = net plantation area x mean tree biomass<br />
increment (MTBI) X carbon proportion (CP) x carbon to carbon dioxide factor (CCF), where:<br />
S<strong>of</strong>twood Hardwood<br />
MTBI = SBI + CBI + RBI 9.487 296 11.647 35<br />
SBI (stem biomass Increment) = TSVI x BD 6.72 8.25<br />
TSVI (total stem volume increment) 16 m3 /ha/year 15 m3 /ha/year<br />
BD (basic density) 0.42 t/m3 0.55 t/m3 CBI (canopy biomass increment) = SBI x 0.1765 1.186 08 1.456 125<br />
RBI (root biomass increment) = (SBI + CBI) x 0.2 1.581 216 1.941 225<br />
CP = 0.5 0.5 0.5<br />

In <strong>2007</strong>–<strong>2008</strong>, Forests NSW estimated that there were approximately 3 400 000 t <strong>of</strong> CO2e<br />
sequestered in its planted forests within the Forest Agreement regions (refer to figure 2-5A).<br />
Forests NSW estimates that the sum <strong>of</strong> CO2e sequestered in plantation estate in the UNE, LNE,<br />
Southern <strong>and</strong> Eden regions was approximately 650 000 t, 290 000 tonnes, 2 000 000 tonnes <strong>and</strong><br />
500 000 t, respectively.<br />
