Abstract

This thesis used fluorescence spectroscopy, 1H-NMR and nutrient analyses to investigate fire-related changes in dissolved organic matter (DOM) in forest soils of southwest Australia. Changes in DOM composition of eucalypt forest and pine plantations immediately after fire are more strongly affected by feedbacks between forest type and fire severity than forest type alone. Legacy effects of fire intensity on the composition of DOM is more evident in karri forest burnt at high severity compared to jarrah forest. These findings are crucial to predict how carbon and nutrient cycling in forests may respond to future fire disturbances.
