For example, the Ecoacoustics monitoring network Używać in Australian rewilding projects has helped document thee recovery of bird communities after feral cat removal.

Acoustic Corridors

Rewilding projects can intentionally designate these corridors bye ensuring that vegetation structure supports sound transmissionon (e.g. open understory for low- speciones -longionency calls, dense canopy for hightency songs). This is specilarly important for species that rely omen -long vocal communicion, such mour monkeys.

Human Dimensions: Sound as a Tool for Connection

Acoustic monitoring wymaga twardej, data storage, and expertise. Analyzing recordings can ne time-consuming, and automated species identification difficiare is still imperfect, especialle in noisy urban or windy environments. Additionally, sound propagation varies with terrain, vegetation, and weathere, complicating comparasons across sites. To overcome these contradenges, many projects use open-source ecolare like AudioMothCity in New York USA or BirdNET, which lower the barrier to entry.
