The impact of noise on trees

Scientists have long known that noise pollution affects birds and animals. A new study suggests that the detrimental effects have trickled down to plants as well and the risks can be long-term.

Noise from construction, industry, and the building of infrastructure such as roads and pipelines has increased dramatically in the recent years, and with urban growth, human establishments such as industries are being set up closer to forests. Scientists have been documenting how animals and birds respond to a noisy world – some birds sing at higher frequencies; bats have trouble finding prey; frogs struggle to find mates; and whales vocalise louder to communicate with each other. has shown how these effects trickle down to trees and plants, even after the sources of excess noise are removed. Scientists suggest that noise pollution can pose long-term risks that could change the habitat for a whole plethora of species.
