Estimating carbon stocks in Korean forests between 2010 and 2110: a prediction based on forest volume.age relationships

This study was focused on attempting to estimate the potential change in forest carbon stocks between 2010 and 2110 in
South Korea, using forest cover maps and National Forest Inventory (NFI) data. Allometric functions (logistic regression
models) of volume–age relationships were developed to estimate carbon stock change during the next 100 years for Pinus
densiflora, P. koraiensis, P. rigida, Larix kaempferi and Quercus spp. As a result, we found that the average forest
volume would increase from 126.89m3/ha to 246.61m3/ha and the average carbon stocks would increase from 50.51Mg
C/ha to 99.76Mg C/ha during the next 100 years. The carbon stocks would increase by approximately 0.5Mg C/(ha.yr), a
high value if other northern countries’ (Canada, Russia, China, etc.) rates of increase are considered, as these are .0.10 to
0.28Mg C/(ha.yr) as determined in a previous study. This can probably be attributed to the fact that the change in carbon
stocks was estimated without the consideration of mortality, thinning, and tree species’ change in this study, which is may
lead to somewhat overestimation of carbon sequestration. However, this study is meaningful, as the estimated carbon
stocks were based on the data from NFI and forest cover maps.
