Tropical Rangeland Acoustic Recordings from Australian Savanna

Aggregating long-term environmental audio recordings from the Fletcherview Tropical Rangeland SuperSite in Queensland, Australia. Four acoustic recorders were deployed in 2020, with two placed in wet habitats and two in dry habitats, to continuously capture the soundscape. The data can be used to identify sound sources, characterize the acoustic environment, and monitor biodiversity and environmental changes.

Use Cases

• Identify and classify sound sources of interest, such as specific fauna calls, within the continuous audio recordings.
• Characterize the soundscape by analyzing acoustic patterns across wet and dry habitat recorder locations.
• Assess fauna biodiversity by monitoring temporal trends in acoustic activity captured by the long-term recorders.
• Track environmental changes by comparing audio signatures from the established dry and wet seasons.

Strengths

• Data collection began in 2020, providing a multi-year time series for temporal analysis.
• Four recorders provide spatial coverage across both wet and dry habitat types within the site.
• Recordings are continuous, enabling detailed soundscape characterization and event detection.

Limitations

• Specific technical details like audio format, sample rate, and recording duration per file are not provided.
• The dataset description lacks concrete metrics such as total recording hours, file count, or data volume.
• Accessibility and structure of the audio files are unclear as file formats listed are HTML, PNG, and PDF.
