The Eucalyptus woodland free-air CO2 enrichment (EucFACE) facility is the only one of its kind in the southern hemisphere, and provides unparalleled access for intensive study of canopy and soil processes and native biodiversity in a mature Eucalyptus woodland. EucFACE’s infrastructure is located in native Eucalyptus woodland of the Cumberland Plain in the western part of the Sydney basin. EucFACE was established in 2010 following recommendation to the Commonwealth to understand how rising atmospheric CO2 concentration and CO2 fertilisation affects tree canopy processes and soil and ecosystem function in an Australian native woodland. The experiment is located in the drier and warmer part of the Sydney basin, receiving 800mm rainfall per annum with periodic droughts.
Previous FACE experiments in Australia include OzFACE in Yabulu, Qld and TasFACE in Hobart, Tasmania. However, these previous experiments were conducted with short-stature, herbaceous vegetation whereas the current effort focuses on mature native Australian woodland vegetation. Native woodlands of the Cumberland Plain once covered more than 30% of the Sydney basin but remnants of the Cumberland Plain woodland are now threatened by weed invasion, Sydney's urban sprawl and climate change. The experiment aims to understand C sequestration above and belowground under rising atmospheric CO2 concentrations and under Australian conditions with dynamic changes in water availability within and amongst years.
The EucFACE experiment is overseen by a committee within the Hawkesbury Institute for the Environment and by the FACE Scientific Advisory Committee. The latter includes participation by national and international leaders in the fields of plant ecophysiology, soil microbial function, ecohydrology and ecosystem modelling.
