    This data contains a once-off general structural description according to the National Vegetation Information System (NVIS) level 5 for the core 1 hectare plot in the Alice Mulga site in 2012. Dominant growth form, cover, height and species (up to 5 species in order of dominance) for up to 3 sub-stratum per traditional strata (Ground, Mid and Upper).

    <p>This dataset contains audio files from Warra Tall Eucalypt SuperSite. Warra Tall Eucalypt SuperSite was established in 2012 and is located in a stand of tall, mixed-aged <em>Eucalyptus obliqua</em> forest (1.5, 125 and &gt;250 years-old) with a rainforest / wet sclerophyll understorey and a dense man-fern (<em>Dicksonia antarctica</em>) ground-layer. The site experienced a fire in January 2019, which consumed the ground layer and killed a high proportion of the understorey trees, but stimulated dense seedling regeneration. For additional site information, see <a href="https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/warra-tall-eucalypt-supersite">Warra Tall Eucalypt SuperSite</a></p> <p>In 2012 an acoustic recorder was set up to collect 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 sensor also recorded temperature, minimum- maximum- and mean-sound pressure levels. The sensor stopped working in 2019 when it was destroyed by a fire.</p> <p>Acoustic indices and false colour spectrograms were created for the recordings. Acoustic indices are summaries of the distribution of the acoustic energy in a recording. They are particularly useful for the analysis of long-term recordings of the environment and can be used to identify sound sources of interest, characterise the soundscape, aid in the assessment of fauna biodiversity, monitor temporal trends and track environmental changes. False colour spectrograms are visual representation of individual acoustic indices or combination of multiple indices. They can highlight the presence of specific sound sources, e.g. birds, insects or weather events, providing a tool for navigating long-term recordings.</p> <p>Data are made available through the data link.

    Gentry transects were established to monitor the vegetation abundance, cover and structure of the mid-stratum and subordinate stratum of the core 1 ha plot in the Samford Peri-Urban site in 2012 and 2017.

    This dataset consists of images of fauna, flora, fungi or general scenery or events captured at the site on an ad-hoc basis and may provide the researcher with information regarding the species that occupy, frequent or traverse this site.<br /> <br /> Tumbarumba Flux site was established in 2000 and started measuring in 2001. The 1 hectare SuperSite plot was established in 2015. Preliminary images have been captured since 2000 using various sampling strategies and protocols. The overstorey is dominated by <em>Eucalyptus delegatensis</em> and <em>Eucalyptus dalrympleana</em>. For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/tumbarumba-wet-eucalypt-supersite/ .<br /><br /> Other images collected at the site include digital cover photography, phenocam time-lapse images taken from fixed under and overstorey cameras, and photopoints. <br /><br /> <iframe src="https://maps.google.com/maps?layer=c&amp;panoid=M8Y1wzLaKZkAAAQfCUGTcg&amp;ie=UTF8&amp;source=embed&amp;output=svembed&amp;cbp=13%2C256.70292604843684%2C%2C0%2C-24.374810904891447" title="Tumbarumba Wet Eucalypt SuperSite - Winter 2014" style="height:248px;width:462px;"></iframe> <br />Tumbarumba Wet Eucalypt SuperSite - Winter 2014<br />

    <p>Fixed cameras installed at the Gingin Banksia Woodland 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 hourly during daylight hours. Images and data products, including timeseries of the Green Chromatic Coordinate (Gcc) for a region-of-interest (ROI) that delineates an area of specific vegetation type, are made available on an almost real-time basis.</p> <p>The Gingin Banksia Woodland SuperSite was established in 2011 and is located in a natural woodland of high species diversity with an overstorey dominated by Banksia species. For additional site information, see https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/gingin-banksia-woodland-supersite/.</p> <p>Other images collected at the site include photopoints, hemispherical upward photographs, and ancillary images of fauna and flora. </p>
