Sounds of the forest.

A recent survey in Costa Rica is using audio recordings to monitor the biodiversity of the country's forests. The survey, which is the largest of its kind, involves placing microphones at over 600 sites in different forest ecosystems. By comparing the soundscapes of regenerating forests with those of intact forests, researchers hope to determine if large-scale forest restoration brings back the full diversity of ecosystems. The survey could have implications for changing the way biodiversity is monitored worldwide, and the data collected will be uploaded to an open-source web platform for tracking ecosystem restoration projects globally.
