Table 1. The principal techniques presently used for active
restoration and remediation after disturbance. Unlike most of these
approaches that are best suited to scheduled site-scale initiatives,
acoustic restoration is scalable, readily tailored to both aquatic and
terrestrial applications and can be rapidly deployed in remote or
dangerous landscapes.
Figure 1. Comparison of soundscapes before and after rain at
Clump Lagoon, French Island, Australia using long-duration false-colour
spectrograms. The X-axis is 24 hours (midnight to midnight), y-axis
0–11,000 Hz generated by three acoustic indices (ACI acoustic
complexity index, ENT spectral entropy and EVN event count index). In
addition to quantifying community-wide recovery in wetland-dependent
species following drought-breaking rainfall, chorusing insects,
songbirds, and individual species can be readily distinguished. This
before / after comparison exemplifies the whole-of-system variation
encompassed by soundscapes, images that are both high resolution
benchmarks informing restoration practitioners and powerful
communication tools for the community groups, funding agencies and
policy makers investing in on-ground improvements.
