<p>This dataset lists the parameters associated with disturbance from Rangeland sites across Australia described by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. </p> <p> For each site, the disturbance parameters such as erosion type, state of erosion, extent of erosion is studied following the AusPlots Plot Description protocol and becomes an important part of understanding the site disturbance in the AusPlots Rangelands.</p>

<p>This dataset comprises a comprehensive archive of soil subsite samples collected from TERN Ecosystem Surveillance monitoring plots across Australia. In addition to the 1-meter soil pit, soil subsite samples are taken from nine locations across the 1-hectare monitoring plot from three depths (0-10cm, 10-20cm and 20-30cm). Each of the nine subsites are selected to represent the variation in micro habitats across the monitoring plot. Collected following the standardised Ecosystem Surveillance methodology, the dataset includes over 33,600 soil subsite samples archived in the TERN Australia Soil and Herbarium Collection, located at the University of Adelaide's Waite Campus.</p> <p>Each record includes detailed metadata such as voucher barcode for soil collected from the three depths at each of the nine subsites, site and visit information and sampling details. Soil subsite samples are accessible and available for loan upon request through the EcoPlots Samples portal via an Expression of Interest.</p>

<p>This dataset comprises a comprehensive archive of soil metagenomic samples collected from TERN Ecosystem Surveillance monitoring plots across Australia. In addition to the nine subsite locations across the 1-hectare monitoring plot, soil metagenomic samples are collected from the top layer of soil. These samples can support microbial DNA analysis, including assessments of soil biodiversity, microbial function and ecological responses to environmental change. Each of the nine subsites are selected to represent the variation in micro habitats across the monitoring plot. Collected following the standardised Ecosystem Surveillance methodology, the dataset includes over 10,400 soil metagenomic samples archived in the TERN Australia Soil and Herbarium Collection, located at the University of Adelaide's Waite Campus. </p> <p>Soil metagenomic samples are preserved under climate-controlled conditions to maintain DNA integrity for future molecular analysis. These samples are openly available to researchers and support a broad range of ecological, agricultural, and microbiological studies. Each record includes detailed metadata such as voucher barcode, site and visit information and sampling details. Soil subsite samples are accessible and available for loan upon request through the EcoPlots Samples portal via an Expression of Interest.</p>

<p>This dataset lists land surface characteristics observed in Rangeland sites across Australia by the TERN Ecosystem Surveillance team, using standardised AusPlots methodologies.</p> <p>Land surface observations are collected at each site as part of the AusPlots method. At each site, observations on ground cover, lithology, erosion (state, extent, and human accelerated), surface drainage, microrelief, aspect and angle are recorded as part of the Ausplots Ground cover and Plot description methods.</p>

<p> TERN Ecosystem Surveillance is a plot-based field monitoring platform that tracks the direction and magnitude of change in Australia’s environments. Information on soils and vegetation is collected according to standardized, widely endorsed and consistent protocols across all plots, and includes the collection of soil and vegetation samples for subsequent analysis.</p> <p>Data collected by TERN is stratified across the entire continent to ensure adequate coverage of major Australian ecosystems, and measures are repeated at least once a decade, with the aim to establish replicate plots throughout the ecosystem types existing within Australia’s Major Vegetation Groups (MVG’s). Additional plots located in key environmental transition zones will be re-measured every five to ten years.</p> <p>TERN users include researchers, land managers and policy-makers who require access to terrestrial ecosystem attributes collected over time from continental scale to field sites at hundreds of representative locations. TERN provides model-ready data that enables users to detect and interpret changes in ecosystems. In addition, TERN curates The TERN Australia Soil and Herbarium Collection, with over 180,000 vegetation and soil samples (and associated contextual environmental data), available to loan through the EcoPlots Samples portal via an Expression of Interest.</p> <p>TERN’s world-class surveillance monitoring infrastructure will support long-term ecological inventory, environmental monitoring, environmental prediction, reporting and assessment, and underpin decisions about our greatest environmental challenges.</p>
