Calperum Mallee Acoustic Data Collection - TERN

<p>This dataset contains audio files for TERN Calperum Mallee SuperSite. Long-term recordings of the environment 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.</p> <p>The site was established in 2010 and is located on Calperum Station, near Renmark, in South Australia. The property was a pastoral grazing lease for nearly 150 years, and suffered grazing-induced modifications to its ecosystems that are now being actively restored following removal of sheep in 1994. The area includes mallee woodlands and riverine vegetation. A significant amount of the mallee woodlands was burnt in January 2014. The mallee species are multi-stemmed eucalyptus trees (<em>Eucalyptus dumosa</em>, <em>E. incrassata</em>, <em>E. oleosa</em> and <em>E. socialis</em>) while the sparsely distributed mid-storey species come from <em>Eremophila</em>, <em>Hakea</em>, <em>Olearia</em>, <em>Senna</em> and <em>Melaleuca</em> genera. The spaced understory is predominately clumps of spiny grass (<em>Triodia spp.</em>). For additional site information, see <a href="https://www.tern.org.au/tern-observatory/tern-ecosystem-processes/calperum-mallee-supersite">Daintree Rainforest SuperSite</a></p> <p>In 2013 two acoustic recorders were 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.</p> <p>Data are made available through the data link.
