Scientists utilise new eco-acoustic technologies to better understand forests

ABC NEWS (Australia)

Scientists are listening to hours of forest soundscapes to help them better understand their unique ecosystems. Eco-acoustics is harnessing the power of AI to capture the fingerprint of WA southwest forests.

00:00 Lauren Hawkins is listening to this area of Jarrah Forest near Mundaring in the Perth

00:08 Hills.

00:09 I want to find out what is making the sounds and then learning how this information, how

00:18 we can use that to make sure that we're conserving and managing these forests into the future.

00:25 Out in the bush, Ms Hawkins sets up small recording devices.

00:29 These wonderful nifty little devices here, very, very small.

00:34 They get set up, can be put up in a tree or on a picket, on a dropper, and they record

00:40 the sound waves of whatever is making sound in the environment.

00:47 Over time, the recordings will allow scientists to monitor the health of an ecosystem by monitoring

00:53 what native species are present and also what invasive species are active in an area.

00:58 This way of using eco-acoustics is a relatively new field of science.

01:03 It has great potential for application because it's cost effective, it's non-invasive, it

01:10 can be, you can put it into remote places, they can be out for a long period of time

01:17 and can collect very high resolution data.

01:21 Back in the office, scientists have hundreds of hours of data to analyse.

01:25 But with the introduction of AI, that job is becoming easier.

01:29 We're still in the journey of this tool being developed to be applied to mainstream monitoring

01:34 practices but we're on our way and it's really exciting to be a part of.

01:39 The project is expanding to capture soundscapes from bushland throughout the south-west of

01:43 the state.

01:45 It's an absolute privilege to be able to walk in nature and have that connection of closing

01:52 your eyes and listening.
