Termites are estimated to contribute between <5 and 19% of the global methane (CH4) emissions. We measured CH4 fluxes from four common mound-building termite species (Microcerotermes nervosus, M. serratus, Tumulitermes pastinator and Amitermes darwini) diurnally and seasonally in tropical savannas in the Northern Territory, Australia. Our results showed that there were significant diel and seasonal variations of CH4 emissions from termite mounds and we observed large species specific differences.

This project asses the utility and performance of the National Carbon Accounting Toolbox (NCAT), particulary its Full Carbon Accounting Model (FullCAM), for estimating carbon stocks and fluxes throughout the Northern Territory. The NCAT has been developed by the Australian Greenhouse Office as an integral component of the National Carbon Accounting System (NCAS). The report is presaged by caveats because the NCAT has not been fully parameterised for troical savannas in Australia.
