    Abstract

    The impacts of fire on the surface radiation and energy balance of Australian savannas was investigated. The heat fluxes, moisture and carbon dioxide were measured over typical tropical savanna using the eddy covariance technique. The net ecosystem production (NEP) of the site including the losses from burning were +0.8 and +0.3 tC.ha-1 for the years 2001, 2002, 2003 respectively, indicating that in years with fire that ecosystem is a net source to the atmosphere. Enhanced biomass productivity of 30 to 60% after burning has been observed in some humid Savanna studies. Savanna management would be potential for increasing carbon storage in ecosystems by reducing fire frequency.
