The native forests of Griffith University contribute a range of important ecosystem services and functions including sequestering carbon, and hence are an important component of Griffith University’s Sustainability Goals including in relation to the United Nations Sustainable Development Goals SDG13: Climate Action as well as SDG15: Life on Land. To estimate the carbon currently stored within the native forests on the Nathan campus of Griffith University, and potential for future carbon sequestration, field estimation of the carbon in the forests was undertaken along 14 transects across 7 of the 12 Regional Ecosystems (RE) on the campus in 2023. Specifically, Above Ground Biomass was estimated by converting measurements of the height and width of all wood plants and standing dead trees with a Diameter at Breast Height of 5cm along 14 10m * 50m transects (two per RE, randomly located) using standard allometric calculations. These field values were then converted to tons of Above Ground Carbon per ha (12.5.3a = 98.1, 12.9‐10.17c = 155.2, 12.9‐10.26 = 168.2, 12.9‐10.4 = 141.3 12.11.24 = 177.2, 12.11.25 = 106.8, 12.11.26 = 94.4, weighted average across RE = 150 t C ha‐1 ) which when combined with the area of each sampled RE and other RE on campus (144.6 ha) to give a final estimate of the amount of Above Ground Carbon (21,749 t carbon) (living and standing dead) as well as both Above and Below (in roots) Carbon in woody plants (living and standing dead) (27,186 t carbon). There were lots of dead standing trees in the forest (20.9% of wood plants). When they were removed from the calculations the carbon values were slightly lower per RE (12.5.3a = 85.1, 12.9‐10.17c = 144.2, 12.9‐10.26 = 161.3, 12.9‐10.4 = 132.3 12.11.24 = 158.5, 12.11.25 = 102.4, 12.11.26 = 64.0, weighted average across RE = 139.4 t C ha‐1 ) while the total Above Ground Carbon in living wood plants was estimated as 20,193 t carbon and both Above and Below (in roots) Carbon in living woody plants was estimated as 25,241 t carbon. These values are broadly similar to those for a range of wet open forests in subtropical Queensland and reflect the generally high BioCondition of the forests at Nathan. It is also possible to estimate carbon flux for the forests on campus based on a rate of 2.92 t ha‐1 y‐1 given for similar forests in the region. Using this value, the Nathan forests may be sequestering carbon from the atmosphere at the rate of 423 t ha‐1 y‐1 . However, too frequent/hot bushfires, further clearing, drought conditions and the spread of weeds will reduce biodiversity in the forests and their capacity as carbon stores and carbon sinks.
