Long-Term Acoustic Recordings From Wombat State Forest

Encompassing long-term environmental audio recordings from the TERN Wombat Stringybark Eucalypt SuperSite, established in 2010. Recordings were collected for 12 hours per day, split between dawn and dusk periods, starting in 2013. The sensor also captured temperature and sound pressure level data.

Use Cases

• Analyze long-term spectrograms (PNG files) to identify and monitor trends in bird chorus activity during dawn and dusk recording periods.
• Use temperature and sound pressure level data recorded by the sensor to correlate environmental conditions with acoustic activity.
• Characterize the soundscape of dry eucalypt forest to aid in the assessment of fauna biodiversity over time.
• Track environmental changes by comparing acoustic signatures and sensor data across the recording period from 2013 onward.

Strengths

• Long-term recordings initiated in 2013, providing a multi-year time series.
• Data collection targets 12 hours per day, specifically capturing biologically active dawn and dusk periods.
• Includes supplementary sensor data for temperature and sound pressure levels alongside audio.
• Recordings are from a well-established ecological monitoring site operational since 2010.

Limitations

• The dataset consists of large audio files (HTML, PNG, PDF), requiring specialized tools and storage for analysis.
• No columnar or tabular data sample is provided, limiting immediate analytical exploration.
• The geographic scope is limited to a single 1-hectare plot within the Wombat State Forest.
