    <p>Fixed cameras installed at the Whroo Dry Eucalypt Affiliate SuperSite provide a time series of fine scale data as a long-term record of vegetation structure and condition. This dense time series of phenocam images provides data for analysis of ecological responses to climate variability, and when consolidated across the entire terrestrial ecosystem research network, supports calibration and validation of satellite-derived remote sensing data, ensuring delivery of higher quality results for broader scale environmental monitoring products. </p> <p>Images are captured half hourly during daylight hours. Images from 2013 to 2017 are made available. </p><p> The site was established in 2010 in box woodland dominated by <em>Eucalyptus microcarpa</em> (grey box) and <em>Eucalyptus leucoxylon</em> (yellow gum). For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/whroo-dry-eucalypt-supersite/. </p><p>Other images collected at the site include photopoints, digital cover photography (DCP), panoramic landscape, and ancillary images of fauna and flora. </p>

    <br>The aim of this project is to compile land use and management practices and their observed and measured impacts and effects on vegetation condition. The results provide land managers and researchers with a tool for reporting and monitoring spatial and temporal transformations of Australia’s native vegetated landscapes due to changes in land use and management practices. Following are the details about the Taroom Shire Potters Flat. </br><br> Pre-European benchmark-analogue vegetation: The site was originally brigalow <em>Acacia harpophylla</em>, mixed community associated with overstorey several species, including <em>Eucalyptus coolabah</em>, <em>E. cambageana</em>, <em>Casuarina cristata</em>, and a range of understorey species, grassy woodlands and open forests. </br><br> Brief chronology of changes in land use and management:<ul style="list-style-type: disc;"> <li>1860: Area used for sheep grazing by shepherds</li> <li>1870: Permanent fences established</li> <li>1875: Start of continuous or set stocking with sheep</li> <li>1880: Incursion of prickly pear started</li> <li>1904-1929: Continuous grazing with sheep</li> <li>1929-1932: Gradual increase in cattle numbers, decline in sheep</li> <li>1930-1935: Land clearance via ringbarking</li> <li>1932-1970: Almost continuous grazing with cattle - relatively low stock numbers</li> <li>1935: Prickly pear had been destroyed</li> <li>1940-1955: Re-clearing brigalow regrowth with axes and fallen timber burnt</li> <li>1956-1960: Brigalow regrowth left unchecked</li> <li>1960-1962: Brigalow regrowth pulled mechanically and burnt</li> <li>1962-1970: Regrowth commenced restabilising without treatment or control</li> <li>1970: Area/s designated as blocks to be left as shelter belts for cattle</li> <li>1970: Commenced managing areas surrounding the site regrowth (i.e. shelter belt) mechanically</li> <li>1971-2010: Areas surrounding the site regularly and intensively managed with ploughing, fertilising the pasture and cropping</li> <li>1971-2010: Site almost continually used as shelter belt for cattle - high use.</li></ul></br>

    The datafile contains the composition and abundance of airborne pollen in the campus of the Australian National University, Canberra, ACT, Australia. The data was collected for the period between September 2007 to December 2009 as part of a large research program looking at atmospheric particles and human health and phenology of urban planted environments (unpublished).

    <p>This dataset contains audio files from Robson Creek Rainforest SuperSite. The 25 hectare site lies on the Atherton Tablelands in the wet tropical rainforests of Australia at 680-740&nbsp;m elevation. It is situated in Danbulla National Park within the Wet Tropics World Heritage Area. The forest is classified as Regional Ecosystem (RE) 7.3.36a, complex mesophyll vine forest. The climate is seasonal with approximately 60% of rain falling between January and March and the landform is moderately inclined with a low relief. There are 208 species in the site, and maximum canopy height is 44&nbsp;m. All stems ≥ 10&nbsp;cm diameter are measured, tagged and mapped. For additional site information, see <a href="https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/robson-creek-rainforest-supersite">Robson Creek Rainforest SuperSite</a></p> <p>In 2020 four acoustic recorders were set up to collect audio data continuously as part of the Australian Acoustic Observatory (A2O) project. Two recorders were placed in relatively wet habitats and two in relatively dry habitats.</p>

    Statewide composite of fire scars (burnt area) derived from all available Sentinel-2 images acquired over Queensland. It is available in both monthly and annual composites. Fire scars have been mapped using an automated change detection method, with supplementary manual interpretation. This data contains both automated and manually edited data.

    The data set contains information on the soil water content at various depths in the Samford Ecological Research Facility (SERF), Samford Peri-Urban Site. Information on soil water content is provided from two sensors, i.e., 1) Sentek Solo, for high frequency sampling and 2) Sentek Diviner, for coarser resolution sampling.

The recorder collected audio data for a total of 12 hours per day, split between six hours around dawn and six hours around dusk. The recording schedule aimed at capturing morning and evening bird choruses while minimizing memory and battery requirements. A long-term spectrogram has been generated for each audio file to aid in data exploration. The sensors also recorded temperature, minimum- maximum- and mean-sound pressure levels.</p> <p>Data are made available through the data link.
