<p>This dataset lists the occurrence of fungi and their abundance identified at rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. </p> <p>Fungi occurrences (i.e. a sample of a fungi at a particular point and time) are methodically identified at each site as part of the AusPlots Point intercept method. Fungi occurrences data can be aggregated across the site to calculate relative abundance, fungi ground cover.</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>This dataset comprises a comprehensive archive of soil pit samples collected from TERN Ecosystem Surveillance monitoring plots across Australia. Soil is characterised from a 1-meter soil pit located near the southwest corner of each 1-hectare monitoring plot. A soil sample is collected down the soil profile from each recognised horizon, and are collected as part of the soil characterisation process including detailed morphological and profile descriptions. Collected following the standardised Ecosystem Surveillance methodology, the dataset includes over 5,800 soil pit 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 each horizon at the soil pit, site and visit information and sampling details. Soil pit 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 plant species and their abundance identified at rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies. </p> <p>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.</p> <p>In addition, at least one specimen is taken from each species at the site, assigned a barcode and provided for vouchering and further analyses.</p>

<p>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. </p> <p>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.</p>

<p>This dataset lists soil profile observations described in the rangeland sites across Australia by the TERN Surveillance Monitoring team, using standardised AusPlots methodologies.</p> <p>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&amp;nbsp;m+ method. Soil specimens for the soil horizons are also collected for preservation.</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>

This dataset comprises a comprehensive collection of plant voucher specimens representing vascular plants sampled from TERN Ecosystem Surveillance monitoring plots across Australia. These specimens are essential for accurate species identification and verification, providing a complete inventory of vascular plant species present at each plot. Collected following the standardised Ecosystem Surveillance methodology, the dataset includes over 57,000 accessioned vascular plant specimens housed at the TERN Australia Soil and Herbarium Collection, located at the University of Adelaide's Waite Campus.<br></br> Each record includes detailed metadata such as voucher barcode, site and visit information, sampling details, and digitised images where available. Plant voucher specimens are accessible and available for loan upon request through the EcoPlots Samples portal via an Expression of Interest.
