The project systematically surveys the extent and condition of remnant native vegetation on railway corridors / roadsides . A standard drive-by survey methodology is used to record dominant species (overstorey, understorey, emergent, threatened and alien species), structural type, density/distribution and understorey vegetation type in roadside vegetation. Mapping outputs are used to inform roadside vegetation management by Local and State Governments.

The Ground Cover Reference Sites Database of South Australia has been collected by Department of Environment, Water and Natural Resources, South Australia as part of the Ground Cover Monitoring for Australia project. The data is being used to calibrate, validate and improve vegetation fractional cover products derived from remote sensing, in particular the satellite sensors MODIS and Landsat. The data is being used to improve the national fractional vegetation cover product of Guerschman et al. (2009) derived from the Moderate Resolution Imaging Spectroradiometer (MODIS). This algorithm enables national, monthly identification of ground cover separating the photosynthetic and non-photosynthetic components by applying a linear unmixing methodology for spectral reflectance every 8 days as 16-day composites. For confidence in its ground cover estimates, the results were verified in the field at selected sites across Australia to allow more extensive calibration, validation and verification of accuracy of the remote sensing method. The Ground Cover Reference Sites Database represents the results of the field validation of remotely determined cover measurements by observing cover along point intersects with a total of 300 points (or 200 points with crops). It also has additional observations and measures such as landscape features, fire evidence, erosion evidence, biotic disturbance evidence, biomass estimates, basal area measurements, soil features and dominant vegetation species, as well as site photographs. The Ground Cover Reference Sites Database focuses on sites in extensive grazing systems of the rangelands and, to a lesser extent, in the mixed farming or intensive land use zone. Field validation aims at obtaining a wide spatial coverage of sites, with limited site revisits for temporal coverage.

The desert ecology plot network, located in the Simpson Desert in central Australia, aims to track long-term shifts in biodiversity and ecological processes in relation to key drivers, both intrinsic to the resource pulse dynamics and due to human disturbance. These drivers include unpredictable rainfall and droughts, fire, feral predators and grazing.

TREND will provide the ecological infrastructure that will: quantify the richness and cover of plant species (including weeds); quantify the diversity and abundance of soil biodiversity; assess the state, spatial heterogeneity and structural complexity of vegetation, including life-stage; record vegetation and soil parameters that assist with the validation of remotely sensed ecological products; analyse vegetation structure and change based on a series of photo reference images; better estimate soil carbon and nutrient stocks; conduct taxonomic validation studies based on collected plant voucher specimens; conduct DNA barcoding and population genetic profiling based on collected tissue samples. The collation of these data will: increase understanding of the dynamics of plant species and soils; substantially increase knowledge of the carbon and other important nutrient budgets across an environmental gradient; improve quality of remote sensing products; input into DNA barcoding of Australian vegetation; help understand the biogeography underpinning and threatening processes impacting South Australian ecosystems; assist state and federal agencies to meet their monitoring and reporting obligations; create a photographic reference of South Australia&#39s bioregions to enhance existing state photo reference libraries; enable researchers and land managers to assess current land state for a variety of purposes depending on how the data is used; identify the climate zones, bioregions, land types and ecosystems where changes are occurring and the management regimes and/or pressures contributing to these changes. Overall this information will progress understanding of ecosystem processes, structure and function, and more generally progress understanding of the response to disturbance and longer term environmental change of rangeland ecosystems, which underpins sustainable management practice. Under the Biome of Australia Soil Environments (BASE) project, soil samples are collected at 14 TREND sites for subsequent physical/chemical and metabarcoding analysis.
