Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.

甲烷是一种极其有效的温室气体。最近的证据表明，树木介导的通量可能是大气中甲烷的一个重要但被忽视的来源。该项目旨在量化澳大利亚主要森林类型中树木介导的甲烷通量的大小和驱动因素。创新地，我们将采用基于经验的现场测量、气体示踪实验、微生物分析和建模方法的新颖组合。预期成果是对树木介导的甲烷通量的机械理解，有助于限制区域、国家和全球甲烷预算。这项研究的结果将有助于为公共资助的温室气体减排战略提供信息，确保投资回报最大化。
