Human Voices Near Salmon Streams Scare Off Bears and Eagles, Disrupting Forest Nutrients Recent studies on the impact of human noise on wildlife behavior in temperate rainforests have shed new light on an issue that affects not just these ecosystems but also the people who depend on them.
Research from Alaska and British Columbia demonstrates that the sound of human activity can disrupt the delicate balance between predators like bears and eagles, and their prey.
Experiments conducted by Philip Manlick's team in the Hén Latinee Experimental Forest near Juneau, Alaska, used motion activated cameras and speakers to play recorded human voices, off highway vehicle sounds, and natural seabird noises.
