<p>This dataset lists the parameters associated with plant population from Rangeland sites across Australia described by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. </p> <p> For each species in the plot, their basal area is derived using the TERN basal wedge across different spatial points in the plots, are described using AusPlots basal sweep sampling points methods. Other recorded information includes the number of sampling points. Species identification is updated once confirmed by Herbaria records. Plant population data can be aggregated across the site to calculate relative species abundance, species- growth form- and -community-level basal area. In addition, TERN has derived the IUCN and EPBC conservation status of each tree species under study following the latest status listed in their databases.</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>
