Claim · model-written summary
Harvesting Quercus ellipsoidalis aboveground biomass would yield net belowground carbon sequestration but less aboveground biomass.
- Taxon
- Q. ellipsoidalis
Quercus ellipsoidalise0e1
Verbatim
e0“Conversely the harvest of Q. ellipsoidalis aboveground biomass would result in net sequestration of carbon belowground due to its high allocation belowground, but would yield lower amounts of aboveground biomass.”
e1“Plant carbon gains with P. strobus were paralleled by a decrease of 16% in soil carbon”

Other claims from this paper (16)
- Observation After five years Pinus strobus had 6.5 times the harvestable aboveground biomass of Quercus ellipsoidalis.
- Observation After five years Pinus strobus had ten times the harvestable aboveground biomass of grassland species.
- Observation Pinus strobus accrued the largest total plant carbon pool, 1375 g C per square metre.
- Observation Schizachyrium scoparium had the largest grassland total plant carbon pool.
- Observation Quercus ellipsoidalis accrued 850 g C per square metre.
- Observation Quercus macrocarpa accrued 370 g C per square metre.
- Observation Poa pratensis accrued 390 g C per square metre.
- Observation Solidago canadensis accrued 132 g C per square metre.
- Observation Lespedeza capitata accrued 283 g C per square metre.
- Observation Pinus strobus and Quercus ellipsoidalis were the only species with significant carbon sequestration.
- Observation Total ecosystem carbon accumulation varied across species from −21.3 to +169.8 g C per square metre per year.
- Association Pinus strobus plant carbon gains coincided with a 16% decrease in soil carbon.
- Association Quercus ellipsoidalis plant carbon gains coincided with a nonsignificant 9% soil carbon decline.
- Observation Pinus strobus allocated most carbon aboveground.
- Observation Quercus ellipsoidalis allocated most carbon to belowground biomass.
- Mechanism Harvesting Pinus strobus aboveground biomass for biofuel would leave no net carbon sequestration because soil carbon declines offset plant carbon gains.
