Great Western Woodlands Acoustic Data Collection - TERN 

This dataset contains audio files for Great Western Woodland SuperSite. The site was established in 2012 in Credo Conservation Park. The site is in semi-arid woodland and was operated as a pastoral lease from 1907 to 2007. The core 1 ha plot is characterised by Eucalyptus salmonophloia (salmon gum), with Eucalyptus salubris, Eucalyptus transcontinentalis and Eucalyptus clelandiorum dominating other research plots. For additional site information, see Great Western Woodlands SuperSite
In 2012 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 sensors also recorded temperature, minimum- maximum- and mean-sound pressure levels.
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.

We at TERN acknowledge the Traditional Owners and Custodians throughout Australia, New Zealand and all nations. We honour their profound connections to land, water, biodiversity and culture and pay our respects to their Elders past, present and emerging.
Great Western Woodlands SuperSite was established in 2012 and is managed by CSIRO Environment. The Western Australian Department of Biodiversity, Conservation and Attractions (DBCA) manages Credo Conservation Park, including the Field Studies Centre and accommodation on site. DBCA are collaborators on a range of projects.
This work was funded by the Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project.
 

Long-term acoustic recordings are collected to characterise the acoustic sources in the ecosystem. Recordings can be used to estimate biodiversity, monitor temporal changes in the soundscape, compare the acoustic characteristics of different locations, and assess the effect of particular events such as bushfires and floods.
