Can Carbon Sequestration in Tasmanian “Wet” Eucalypt Forests Be Used to Mitigate Climate Change? Forest Succession, the Buffering Effects of Soils, and Landscape Processes Must Be Taken into Account

Table 4

Estimated mean C pools in mixed forests and rainforests of Tasmania and C in each pool expressed as a percentage of total C in the ecosystem. Standard deviations in parentheses.

¹This study. ²From Moroni et al. [11], Table 2. ³There are no studies of root mass in Australian temperate rainforests so the default value based on 25% of aboveground biomass [51] has been used. ⁴The default figure, based on 25% of aboveground biomass [51, 52]. The actual mean (n = 6) for tall eucalypt forest >30 m high is 90 Mg·ha⁻¹ (SE = 19 Mg·ha⁻¹) ([51], p. 62), but as the eucalypts in the mixed forests in this study were mature and close to their maximum height, the larger figure is more likely to be correct.
