20. Plant related science questions
Environmental sensitivity
• How do plants’ drought-coping strategies differ between temperate/winter-
wet and tropical/summer-wet climates?
Predicting variations in traits
• Are reported ‘global’ patterns in plant traits able to predict variations in
traits across the Australian continent?
Plant ecophysiology
• How does stomatal behaviour relate to water availability?
• Which is more important in determining the rate of net carbon gain by an
ecosystem – photosynthesis or respiration?

Developing, testing and deploying new and emerging technologies
TERN was created to provide a nationally coordinated data collection; storage; publishing and sharing infrastructure for Australia.It builds on existing ecosystem data collection networks and aims to becomepart of standard practice in ecosystem science and management in Australia.
There are 15 facilities within TERN.Some will provide snapshot data or mapping products for Australia, while others provide long term recurrent monitoring of biodiversity and/or biogeochemistry data products.
TERN covers the spectrum from data collection to data storage, integration, analysis and synthesis.The Supersite Network provides plot based, recurrent ecosystem monitoring and has close ties to a number of other facilities within TERN.AusCover produces nationally consistent, satellite-based biophysical map products, remote sensing research data, and product validation for Australian conditions.OzFlux is a network Eddy covariance Flux towers that measure energy, water and carbon dioxide fluxes. Each Supersite hosts at least one flux tower.eMAST (ecosystem modelling and scaling infrastructure) is involved in the integration and scaling of biogeochemical and ecological data to develop and apply ecosystem models There are a number of plot based monitoring programs in TERN that work on different scales
LTERN or long term ecological monitoring network, integrates key established plot networks across Australia to tackle critical questions associated with the impacts of disturbance on Australian ecosystemsAusPlots Rangelands uses a standardised 1 ha plot survey method to undertake baseline vegetation and soil surveys across the Australian Rangelands which make up 81% of the continent and is represented in 52 bioregions. AusPlots Forests is amonitoring network that improves our understanding of tree growth, forest productivity and carbon dynamics in tall eucalypt forests in relation to continental-scale environmental gradients. The Australian Transects Network includes sub-continental transects that span biomes and traverse major rainfall, temperature and land-use gradients from the coast to inland areas.Supersites - currently have 10 Supersites spread around the country in different climates and vegetation types.
Each Supersite aims to answer local scientific questions that address ecological processes specific to the different biomes and assist local stakeholders and natural resource decision makers. The use of consistent monitoring protocols across all sites allows new comparisons and key scientific questions to be addressed by the network. For example:Do contrasting ecosystems differ in their vulnerability to extreme weather events such as droughts and heat waves?Can ‘tipping points’ be identified, and do those tipping points differ among contrasting environments?
The Supersite network works collaboratively with other facilities within TERN including AusCover, which collects remote sensing data from satellites and airborne platforms carrying out LiDAR and hyper-spectral scanning, terrestrial laser scans, producing digital elevation models and they also run phenocams at the sites.We are currently working with AusCover to refine and validate remote sensing of biomass across different terrestrial ecosystems in Australia.
OzFluxtowers provide data on radiation, heat, water and CO2 fluxes as well as collecting data from soil sensors.The towers also act as platforms for equipment such as phenocameras and acoustic recorders.
There is currently limited faunal monitoring across all sites. Each Supersite has bird surveys and 1 or 2 automated acoustic recorders.Acoustic data from each supersite can be accessed from a dedicated database atBush.fm web page. The data is presented visually and 1 min sections can be selected and played on-line. Analysis tools will soon be added to this web site and working groups developed to progress data handling and analysis strategies.
The ASN data portal can be used to locate data using the clickable map or by using search terms. There are separate databases in TERN for large datasets such as for OzFlux and AusCover data.We have a link to the acoustic recordings database located at Bush.FM. Each acoustic sensor will record terabytes of data per year with some Supersites hosting multiple acoustic sensors.
