Traditionally, ecologists wanting to take stock of the diversity, health and population levels of animal species within a given environment have needed to tie on their boots, get out in the field and painstakingly record what they are able to observe manually. But the emerging field of ecoacoustics – the use of sound recording to survey the biodiversity within ecosystems – is promising to be a game-changer in the way researchers are able to approach this work.

As part of our Science of Sound miniseries, we’re joined by Dr Sarab Sethi, the head of the ecosystem sensing research group at Imperial College London. To talk about his work in this exciting new field.

He tells us how advances in technology are providing new methods of monitoring wildlife in greater detail than ever before and why cross-collaboration between engineers and conservationists is vital in the fight against biodiversity loss.
