Well managed teak stands can contribute towards mitigation of climate change by storing carbon in their solid wood products. However spatial estimates of teaks potential carbon stocks is lacking in the support of precision forest management. The aim of this study was to estimate the carbon in above- and belowground biomass of teak stands and predict their spatial variabilities. Tree data were measured biennially in 46 permanent plots of 213 ha between 2� and 12 year in which thinning was performed at 5 8 and 11 year. Carbon stocks were estimated using equations and geostatistical modelling was carried out by semivariance analyses and ordinary kriging method. Above-ground carbon mean values ranged between 2.95 and 59.10 t ha� with reduction to 57.61 t ha� after third thinning. Minimum and maximum belowground carbon mean values were 0.67 and 8.06 t ha� respectively decreasing to 7.51 t ha� after last thinning. Carbon stocks increased over the years and showed spatial dependence however they were influenced by the thinning. Teak stands presented potential carbon stores since the carbon remained in their solid wood products compared to other species used for energy pulp and paper. This evidence showed the importance of teak in mitigating climate change.

Abstract

Well managed teak stands can contribute towards mitigation of climate change by storing carbon in their solid wood products. However spatial estimates of teaks potential carbon stocks is lacking in the support of precision forest management. The aim of this study was to estimate the carbon in above- and belowground biomass of teak stands and predict their spatial variabilities. Tree data were measured biennially in 46 permanent plots of 213 ha between 2� and 12 year in which thinning was performed at 5 8 and 11 year. Carbon stocks were estimated using equations and geostatistical modelling was carried out by semivariance analyses and ordinary kriging method. Above-ground carbon mean values ranged between 2.95 and 59.10 t ha� with reduction to 57.61 t ha� after third thinning. Minimum and maximum belowground carbon mean values were 0.67 and 8.06 t ha� respectively decreasing to 7.51 t ha� after last thinning. Carbon stocks increased over the years and showed spatial dependence however they were influenced by the thinning. Teak stands presented potential carbon stores since the carbon remained in their solid wood products compared to other species used for energy pulp and paper. This evidence showed the importance of teak in mitigating climate change.
