TERN Ecosystem Surveillance
TERN’s Ecosystem Surveillance platform conducts field surveys and sampling across a national network of plots and transects to provide the data, samples and advice needed for improved monitoring and assessment of Australia’s major ecosystems. The platform helps scientists and land managers better detect and quantify change in vegetation structure and composition, land cover and soil characteristics.

- Soil metagenomics samples
- Vegetation species richness, diversity, abundance and cover
- Vegetation state, spatial heterogeneity and structural complexity
- Soil carbon and nutrient stocks
- Vegetation structure and change based on analysis of series of photo references
- Standardised methods and digital analysis
- Image library collection of three complete panoramas from each plot
- Field survey app for standardised collection of data
- Practical hands-on training

- Create a photographic reference of key Australian bioregions, enhance existing State photo reference libraries.
About Our Plots
Ecosystem Surveillance is a plot-based environmental monitoring program, undertaking baseline assessments of ecosystems across the country. The aim is to establish and maintain a national network of plots and transects that enable consistent ecological assessment and ongoing monitoring.
Analysis of gaps in long-term monitoring in Australia showed arid and semi-arid regions of Australia as under-sampled, particularly Acacia woodlands, Hummock grasslands and Chenopod shrublands. The Ecosystem Surveillance rangelands program was developed to provide information about some of these widespread and yet under-studied environments in Australia.
Whilst lack of information in the rangelands remains a problem, TERN has been remedying the situation by installing plot-based infrastructure that is free for all to use and making data openly accessible. Hundreds of sites have been established across the Australian rangelands, with quality-controlled vegetation and soils data and samples collected according to standardised methods, which have been developed with advice from the research community.
The Ecosystem Surveillance forests program was developed to address information gaps about tall eucalypt forests found in the moister areas of Australia. Whilst these areas had more existing information available compared to rangelands areas, this information had been collected in different ways across the continent. In many locations, data were collected by forestry agencies for production purposes and so missed some important ecological information. Ecosystem Surveillance now collects information using a standardised method from all areas where Tall Eucalypt forests occur in Australia.
About Our Transects
Large-scale transects are powerful tools for addressing key ecological knowledge needs. TERN’s network of monitoring transects facilitates the study of ecological structure and processes over major biophysical gradients to document ecological change and adaptation in relation to climate variation across Australia’s major terrestrial biomes.
Our transects program’s primary focus is observations and monitoring of natural and semi-natural terrestrial ecosystem gradients, generating data and products to enable researchers to predict how species and ecosystems will change in the future. Through the network, research outcomes are linked with and inform management, policy settings, planning and monitoring programs.
TERN transect data help answer the following ecological questions of national significance:
- How do species, communities and ecosystem processes change in space and time, and what are the key processes driving change?
- What is the relative importance of climate as a driver of ecological change?
- Is there predictable variation in ecosystem resilience across bioclimatic gradients, and can environmental thresholds be identified where there are abrupt changes in ecological composition, structure and function?
- What is the potential of species and communities to adapt to a changing climate?
TERN maintains a national network of subcontential transects which traverse major biomes, land tenures (including agricultural landscapes and bioclimatic gradients:
- Biodiversity Adaptation Transect Sydney (BATS)
- North Australian Tropical Transect (NATT)
- South-Western Australian Transitional Transect (SWATT)
- Transect for Environmental Monitoring and Decision Making (TREND)
- Australian east coast Drosphilia Transect (EADrosT)
- Box gum east-west transect (BoxEW)
- Wet tropics altitudinal transect (WTAT)
