Attributing an economical value to forest carbon sequestration might represent is an important strategy to achieve such goals. Such a policy is likely to impact optimal rotation periods in forestry management. However accounting for carbon sequestration alone is not sufficient; the lower surface albedo of forests compared to converted land causes a higher grade of heat absorption, which negatively affects the policy value of forests. Yet due to photosynthesis not all of absorbed energy is converted to heat but partially used as chemical energy.
This thesis discusses the optimum rotation periods and land expectation values of cunninghania lanceolata, under the impact of carbon sequestration and the mentioned radiation budget. This is achieved by comparing three scenario: “just a timber (T),” “timber + carbon benefits (Tcs),” and “timber + carbon + carbon equivalent of radiation budget (Ttecs)”. The findings suggest that in the presence carbon sequestration pricing, the optimal rotation periods and land expectation values ought to increase proportionally to carbon prices and that the relation among optimal rotation periods will be Tcs≥Ttecs≥T (in case the ratio of carbon release is 1).
