The Boyagin Wandoo Woodland SuperSite was established in September 2017 by the University of Western Australia. Located in the Boyagin Nature Reserve, approximately 12 km west of Pingelly, Western Australia the SuperSite monitoring activities complement the Avon River Catchment Critical Zone Observatory at the UWA Future Farm in Pingelly that focusses on managed landscapes (rotational dryland wheat cropping and grazing pastures for sheep). The climate is Semi-arid (Dry) Warm Mediterranean. The Boyagin SuperSite is collocated with the Land Ecosystem Atmosphere Program (LEAP) - Boyagin.
The site provides nationally consistent observations of vegetation dynamics, faunal biodiversity, micrometeorology (climate, radiation, fluxes of carbon and water), hydrology and biogeochemistry to examine the impacts of disturbance, climate on carbon stocks and Green House Gas emissions, and impacts on habitat quality via ongoing monitoring of vegetation structure and fauna. A wide range of ground based observations of vegetation structure and floristics is planned and all will link to remote sensing of fire and vegetation change over time. Measurements of carbon sequestration through time will be achieved via the TERN OzFlux instrumentation capable of directly measuring CO2, water use and surface energy properties (energy balance, reflectance).
Boyagin SuperSite is located in the Avon Wheatbelt (AW2-Re-juvenated Drainage subregion) and has a high density of rare and geographically restricted flora and supports populations of several marsupials subject to fox predation (Numbat, Quenda, Woylie, Tammar, Red-tailed Phascogale, Brushtail Possum) that have disappeared from most of the Australian or Western Australian mainland.
Key research objectives
- Current processes - How do climate drivers influence current processes of production, water use and GHG exchange across contrasting land use types?
- Past changes - How would past climate variability have influenced past production, water use and GHG emissions across contrasting land use types?
- Future response – How might agricultural and native vegetation systems respond to projected climate change and management?
These questions are embedded within a much larger overarching question about "How do intensively managed landscapes in WA alter hydrology, geomorphology, biology, and biogeochemistry?". Such a question is inherently multidisciplinary and can be understood through the lens of ‘critical zone science’. Our second major aim is to undertake this project under the scientific framework of critical zone science and through this project establish the first element of a much larger critical zone observatory (CZO).

TERN OzFlux at the Boyagin Wandoo Woodland SuperSite
OzFlux maintains the flux tower instrumentation that continuously measures exchanges of carbon dioxide, water vapour and energy between the terrestrial ecosystem and atmosphere.
The Ridgefield flux station is located at the Boyagin Wandoo Woodland SuperSite.
Flux data is available from the OzFlux data portal.
