Field‐based Carbon Assessment of the Arboretum at the Logan campus, Griffith University
No full textForests on the campuses of Griffith University contribute a range of ecosystem services and functions including sequestering carbon, and hence are an important component of Griffith University’s Sustainability Goals including United Nations Sustainable Development Goal (UNSDG) 13: Climate Action and UNSDG 15: Life on Land. This includes the 5.2 ha Arboretum at the Logan campus of Griffith University. To estimate the carbon sequestered in the Arboretum over the initial nine years of growth, field work was undertaken in 2023. Specifically, Above Ground Biomass was estimated by converting measurements of the height and width of all woody plants and standing dead trees with a Diameter at Breast Height (DBH) of at least 5 cm in 10m by 15m randomly located quadrats in each of 28 blocks of forest in the Arboretum using standard allometric calculations. These field values were then converted to tons of Above Ground Carbon per ha (38.9 t C ha‐1 ) which was then combined with area of the Arboretum (5.2 ha trees) to give a final estimate of the amount of Above Ground Carbon (192.5 t carbon) as well as both Above and Below (in roots) Ground Carbon in woody plants (240 t carbon). These results demonstrate the importance of the Arboretum where an open area of grass has been turned into a high biodiverse urban forest consisting of over 3,500 trees in 2023 representing 56 species that is cooling the Logan campus, conserving soil, providing habitat for wildlife and wellbeing benefitsfor staff,students and visitors. It has also already sequestered about 29% (Gold Coast) or 27% (Nathan) of the carbon in the native forests on the other campuses. Ongoing management of Arboretum and other wood vegetation on the Logan campus including trees in the Slakes Creek restoration forests, formal gardens and the small area remnant forest at the Logan Campus of Griffith University will ensure they continue to provide benefits including carbon sequestration.Full Tex
Field‐based Forest Carbon Assessment Griffith University, Gold Coast Campus
No full textThe native forests of Griffith University contribute a range of ecosystem services and functions including sequestering carbon, and hence are an important component of Griffith University’s Sustainability Goals including United Nations Sustainable Development Goal (UNSDG) 13: Climate Action and UNSDG 15: Life on Land. To estimate the carbon currently stored within the native forests, and potential for future carbon sequestration, field estimation of the carbon sequestered in the forests on the Gold Coast campus of Griffith University was undertaken in 2023. Specifically, Above Ground Biomass was estimated by converting measurements of the height and width of all woody plants and standing dead trees with a Diameter at Breast Height of at least 5 cm along two randomly located 20 x 50 m transects in the dominant Blackbutt forest Regional Ecosystem (RE) using standard allometric calculations. These field values were then converted to tons of Above Ground Carbon per ha (126 t C ha‐1 ) which was then combined with the current area of intake for the forest on‐campus (29.2 ha) to give a final estimate of the amount of Above Ground Carbon (3,679 t carbon) as well as both Above and Below (in roots) Ground Carbon in woody plants (4,672 t carbon). Furthermore, these forests could be contributing to further carbon sequestration at an estimated rate of 85 t ha‐1 y‐1 . These results demonstrate the importance of the forests on the Gold Coast campus in their role as relatively high carbon stocks when compared to other sub‐tropical forest types in Queensland. It also emphasises their role as carbon sinks when they recover from past logging, and other types of disturbance, with an estimated sequestration of carbon at a rate of 85 t ha‐1 y‐1 . However, they could become a source of carbon (losing more than they sequester) if not appropriately managed, including damage to the few remaining large old trees, which are significant carbon stores, with less than 3% of the trees accounting for more than 52% of the carbon stock on the campus. Inappropriate bushfire management is another important risk that could reduce the sequestration potential of these forests.Full Tex
Field Based Forest Carbon Assessment Griffith University, Nathan Campus
No full textThe 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.Full Tex

The Griffith Tax Clinic
No full textGriffith University (Queensland) was one of 10 Australian universities chosen to be part of the 2019 National Tax Clinic Project. This project sought to expand the foundational work done by Curtin University (Western Australia) to establish student tax clinics across Australia. The objectives of these clinics were to provide greater access to justice for unrepresented taxpayers, a rich learning environment for students, and greater tax literacy for the community. The Griffith Tax Clinic opened its doors to the public in July 2019. This article reports on the experience of the Griffith Tax Clinic, in its first year of operation, and sets out key learning outcomes and recommendations gleaned from that experience.Full Tex
The Sputtering and Characterization of C-Axis Oriented Aluminium Nitride Thin Films On Top Of Cubic Silicon Carbide-On-Silicon Substrates for Piezoelectric Applications
No full textThe growth of micro-scale wireless electronics is increasing significantly because of their miniaturisation and low power consumption. These devices currently draw power from batteries or chemical fuel cells. Their limited life-spans prompt active research to find an alternative solution by harvesting ambient energy from the environment. Numerous sources are available such as solar, thermoelectric, acoustic, and mechanical vibrations. Among them, mechanical vibration is perhaps the most practical to power these wireless electronic devices via piezoelectric transduction. Three most common piezoelectric materials are Lead zirconate titanate (PZT), zinc oxide (ZnO) and aluminum nitride (AlN). AlN is preferred over ZnO and PZT for several reasons. Chiefly among them is because it has the highest electromechanical coupling along the c-axis of wurzite AlN for longitudinal deformation. This thesis investigates the sputtering of c-axis oriented AlN on top of cubic-silicon carbide-on-silicon (3C-SiC-on-Si) substrates for piezoelectric applications. The 3C-SiC buffer layer was used to reduce the lattice mismatch and thermal expansion coefficient between AlN and Si. In the first part of the research, RF sputtering was utilised for depositing AlN. The low growth rate of RF sputtering prompted the switch to DC sputtering. The DC sputtering suffered from electrical arching problems, which were addressed by gradually decreasing the sputtering pressure. However, the system had the limitation of 1200 W of maximum power.Thesis (PhD Doctorate)Doctor of Philosophy (PhD)Griffith School of EngineeringScience, Environment, Engineering and TechnologyFull Tex
Recruitment Ecology of Freshwater Fish in Rivers of Australia's Wet Tropics Region
No full textHydrologic variation has a profound influence on the life cycles of fishes in tropical rivers. Several studies highlighting the critical links between fish recruitment, river hydrology and other environmental factors exist globally. However, understanding of the influence of abiotic drivers on fish recruitment in Australia’s Wet Tropics rivers is limited. There is potential for humans to further alter the hydrologic regimes and the landscapes of these rivers and therefore, gathering knowledge about fish recruitment dynamics is needed to support the implementation of appropriate management strategies aimed at preserving the diversity within the Wet Tropics freshwater fish community. This thesis investigates relationships between key environmental factors – river hydrology, instream habitat structure and food availability – and fish recruitment among five coastal rivers in the Wet Tropics bioregion of north-eastern Australia, and describes how differences in key flow-regime attributes among the rivers may influence these relationshipsThesis (PhD Doctorate)Doctor of Philosophy (PhD)Griffith School of EnvironmentScience, Environment, Engineering and TechnologyFull Tex
