Tumbarumba OzFlux tower site
The Tumbarumba flux station is located in the Bago State forest in south eastern New South Wales.
35° 39' 23.8" S 148° 09' 06" E
It was established in 2000 and was managed by CSIRO, then the University of Queensland.
The tower was rebuild during 2024 and has been upgraded and re-started in February 2025. It is now operated by the University of Melbourne.
The Tumbarumba flux station is supported by TERN and the DCCEE through the ACCSP.
The forest is classified as wet sclerophyll, the dominant species is Eucalyptus delegatensis, and average tree height is 40m. Elevation of the site is 1200m and mean annual precipitation is 1000mm. The Bago and Maragle State Forests are adjacent to the south west slopes of southern New South Wales and the 48,400 ha of native forest have been managed for wood production for over 100 years.
The instrument mast is 70m tall. Fluxes of heat, water vapour and carbon dioxide are measured using the open-path eddy flux technique. Supplementary measurements above the canopy include temperature, humidity, windspeed, wind direction, rainfall, incoming and reflected shortwave radiation and net radiation. Profiles of temperature, humidity and CO2 are measured at seven levels within the canopy. Soil moisture content is measured using Time Domain reflectometry, while soil heat fluxes and temperature are also measured. Hyperspectral radiometric measurements are being used to determine canopy leaf-level properties.
On New Year's Eve 2019 (31/12/2019) a bushfire swept through the Bago State Forest with a moderate severity burn (full understorey consumption but no canopy consumption). Prior to the fire, the forest had been growing without major disturbance over a period of almost 40 years, enabling study of its response to ongoing smaller disturbances such as insect outbreaks, droughts, normal weather fluctuations and internal stand dynamics.
Bushfire disturbance:
The regrowth forest is structurally and functionally different to pre-fire conditions. The fast ground-fire caused nearly 100% mortality of the ash tree species, where the mountain gum (Eucalyptus dalrympleana) species resprouted with epicormic growth. There are high levels of ash regenerating from seedlings and other eucalypt trees (mountain gum and peppermint) are rapidly re-sprouting. There were around 10 months of data gap after the fire.
Extensive tree safety works took place in summer 2024/2025: Forestry Corporation NSW cut down all dead trees along the roads in Bago State Forest, including in the vicinity of the tower and in the supersite.
Tumbarumba OzFlux tower site is part of the TERN OzFlux and TERN Supersite networks.
