On the potential for carbon sequestration in Australia's urban forest for the next decade
MetadataShow full item record
Carbon sequestered in trees is recognized as a valuable resource towards reducing carbon emissions. A methodology is developed to estimate above-ground biomass (AGB) and carbon of the urban forest in 7 towns utilizing existing tree inventory data. Growth rates derived from 69 slab and core samples showed a linear relationship between age and diameter. Species was found to be a key determinant of growth. Carbon density maps revealed that the largest amounts of stored carbon were associated with areas where large, mature trees are located. Infill planting of 8,300 trees over the next 10-20 years will not necessarily increase carbon stock, depending on the quantity and types of trees removed from Council's replacement programs. The outcomes of this research will provide urban forest managers with a simple, yet effective, methodology to estimate, visualize and communicate current and future carbon stocks from inventory data.

Pre-logging carbon accounts in old-growth forests, via allometry: An example of mixed-forest in Tasmania, AustraliaDean, C.; Fitzgerald, N.; Wardell-Johnson, Grant (2011)Uncertainty in past and future anthropogenic carbon emissions obscures climate change modelling. Available allometrics are insufficient for regional-level accounting of old-growth, pre-logging carbon stocks. The project ...
Impact of tree isolation on aboreal and ground ant communities in cleared pasture in the Atlantic rain forest region of Bahia, BrazilMajer, Jonathan; Delabie, J. (1999)The Atlantic rain forest of south-eastern Brazil has been substantially cleared, resulting in the creation of a fragmented landscape. In addition to the small fragments of forest that remain, the pasture is often scattered ...
Has canopy height and biomass recovered 78 years after an intense fire in south-Western Australia's red tingle (Eucalyptus jacksonii) forests?Wardell-Johnson, Grant; Crellin, L.; Napier, C.; Meigs, G.; Stevenson, A.; Wong, S. (2017)Â© IAWF 2017. Tall eucalypt old-growth forests are notable for their large, old (i.e. venerable) trees and have both significant conservation value and high carbon stores. We investigated whether canopy height and biomass ...
