Conservationists and palm oil companies tackling deforestation and forest fires must rely less on satellite imagery and instead start listening to the sounds of the forests, according to a report published on Friday.
The use of “bioacoustics” to record, monitor and log background sounds – like animals, insects and human activity – provides data needed for more effective conservation, researchers said in a paper published by the journal Science.
“You can look at a primary forest, map the soundscapes to see what is normal and then do the same at a logging concession, plantation or hunting area,” said co-author Rhett Butler.
“With a camera trap, you’re at risk of a hunter or poacher coming in and destroying it. But audio equipment you can mount up to 30 metres up a tree and nobody will see them.” Continue reading “To halt deforestation, researchers say we must listen to the forests”
