    This dataset lists land surface substrate characteristics observed in Rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. <br /> Land surface substrate observations are collected at each site as part of the AusPlots Point intercept method. At each site, observations on the substrate type (e.g. rock, coarse woody debris, litter) are recorded on transect laid out on the plots. These records form the basis for ground cover derivation, see the AusPlots Ground cover and Point intercept methods below.<br />

    This dataset list landform characteristics (i.e. visible features of a land area) observed in Rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. <br /> Landform observations are recorded at each site as part of the AusPlots Plots and Physical Descriptions method. Observations on the landform elements and their patterns are recorded as part of this protocol.<br />

    <br>This dataset lists the parameters associated with disturbance from Rangeland sites across Australia described by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. <br /> <br> 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.<br />

    This dataset lists plant species vouchered for identification from Rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. <br /> Plant specimens are methodologically collected at each site as part of the AusPlots Vegetation vouchering method. Recorded information includes the site, date of collection and a voucher barcode. The specimen data is updated with the identification date and authority details when species identification is confirmed by the Herbaria. <br /> Plant population and community, soil, basal area and structural information are also assessed at each site. See AusPlots Vegetation vouchering and Rangelands Vocabularies for a list of parameters collected. </br>

    <br>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. <br /> <br> 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.<br />

    This dataset lists the Vegetation Strata and the three most dominant species in each stratum identified at rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. <br /> Vegetation strata are methodically identified at each site as part of the AusPlots Structural summary and homogeneity method. The information provided includes the type of strata found and the three most dominant species on each stratum.<br />

    <br>This dataset lists plant species and their abundance identified at rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. <br /> <br>Plant occurrences (i.e. a sample of a plant at a particular point and time) are methodically identified at each site as part of the AusPlots Point intercept method. Plant species are identified at each site as part of the AusPlots Vegetation vouchering and Point intercept methods. In addition to site visit date and location, the information provided includes growth form, plant height and whether the plant is dead. In-canopy-sky is also recorded if there is no intercept to foliage or branches when viewing the canopy through the densitometer and can be used to calculate species cover or aerial cover. Species identification is updated once confirmed by Herbaria records. Plant occurrences data can be aggregated across the site to calculate relative species abundance, green ground cover, species- growth form- and -community-level basal area.<br /> <br>In addition, at least one specimen is taken from each species at the site, assigned a barcode and provided for vouchering and further analyses.</br>

    The dataset comprises data from the first survey of ~24,000 large trees (>10 cm diameter at breast height; DBH) within 48 1 ha forest monitoring plots established across Australia between 2011 and 2015. Data includes: [1] Site identifiers (ID and Site Name); [2] Plot Establishment Dates; [3] Tree identifiers and descriptors (ID, Species, Status, Growth Stage, Crown Class); [4] Tree measurements (Diameter, Point of Measurement, Height, Location, above-ground biomass); [5] Comments and ancillary information; and [6] List of Metagenomic Sample Identifiers.

    This dataset lists soil profile observations described in the rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies.<br> Soil profile characteristics are observed and collected at each site as part of the AusPlots Soil and Landscapes methods. For each soil profile sampled, soil horizon's colour, electrical conductivity, effervescence, soil ped characteristics, soil pH, texture and coarse fragments characteristics are described as part of the AusPlots Soil characterisation to 1&nbsp;m+ method. Soil specimens for the soil horizons are also collected for preservation.<br>

    <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 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 150,000 vegetation and soil samples (and associated contextual environmental data) freely available to loan on request.</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> <p>Occurrence records can be accessed through the <a href="https://www.ala.org.au/">Atlas of Living Australia</a>.</p>
