Acoustic Complexity Index (ACI)
Benchmark Value
Scoring Curve
This curve shows how a field measurement for this indicator would score across all available benchmark forms in this context. The scoring engine uses 2 benchmarks together — the OptimalRange form drives the primary score, while 1 guard(s) constrain the result.
Contributing Benchmarks
Evidence & Context
Private Land: Mean ACI of 133.8
Mean spectrogram complexity based on frequency bins (1–11 kHz), calculated from 10-minute daily 95th percentile values across private land managed under restoration schemes.
Reference target point for acoustic complexity in private land under active restoration in Southeastern Australia.
Serves as a clear point reference target for ecologically managed production forests, demonstrating successful biodiversity retention under active human stewardship.
