Modelled carbon stock yield tables
The carbon stock yield tables for the radiata regimes and for the other tree species are shown in comparison in Figure 1. The modelled yield tables are found in Appendix A.

Differences between species, regimes and site quality are evident. Planted kauri shows the lowest carbon accumulation over the 80 years period. Totara sequesters carbon at a similar level. Redwood shows higher sequester rates and approximates the pruned Radiata pine regime on poor sites.
Eucalyptus fastigata shows the strongest early carbon accumulation closely followed by the unpruned radiata regime on good sites.
Modelled pools
C_Change allows the output of various carbon pools (aboveground live biomass, belowground live biomass, dead woody litter and fine litter) that contribute to the overall total of sequestered carbon. Under various regimes the total as well as the allocation in different pools varies. Figure 2 shows the different pools and their differences between an unpruned and a pruned Radiata pine regime on a medium site.
