Peatlands are unique wetland ecosystems that are highly responsive to short-term perturbations caused by humans, and drained peatlands contribute to around 10% of all GHG emissions. Southwestern Australian peatlands are facing challenges exacerbated by climate change, leading to drying, increasing their susceptibility to fire and other disturbances. Since the knowledge of the peatland flora is limited in the Walpole Wilderness Area of southwestern Australia, it is crucial to improve our understanding of the vegetation-fire-hydrology interactions for effective management. My PhD study will investigate the floristic communities and plant fire responses under global warming in the peatlands of Walpole Wilderness Area.
