Abstract
Mitigation and adaptation to climate change in developing countries require sustainable
forest management through either retaining the forest unharvested, i.e., conservation or an
increased need for proper tree harvesting. However, significant number of trees harvested
in miombo woodland of mainland Tanzania are not cut at the specified stump height, i.e.,
15 cm from the ground. Leaving extra stump height (ESH) would escalate wood vol-
ume removals and hence carbon emissions. Better insights on the extent of wood volume
and carbon emissions of ESH in miombo woodlands are apparently needed. This study
intended to estimate volume and carbon of ESH in miombo woodland of mainland Tan-
zania. Based on a sample of 5 264 stumps collected in miombo woodlands of Mainland
Tanzania, total annual volume and annual carbon per hectare of ESH were estimated by
using equation applicable to cylinder in R software. Result revealed that total annual vol-
ume, annual volume and carbon per hectare lost through ESH were 3 800 000 m −3 year −1 ,
0.098 ± 0.034m 3 ha −1 year −1 and 0.028 ± 0.009 tCha −1 year −1 , respectively. The volume and
carbon loss from ESH per hectare per year escalate 6% and 5% of more volume and car-
bon removals, respectively, in the entire miombo woodlands and its categories in mainland
Tanzania. Since annual volume loss of ESH is almost 1⁄4 of annual volume deficit of 19.5
million m 3 year −1 , the deficit and further removals could be lowered through adhering to
appropriate harvesting regulations.
