About this sound
"Vital signs," like blood pressure and pulse rate, are used in medicine to track human health. Paying attention to the little things can often help us better understand what's going on in the big picture. Scientists can monitor ecological "vital signs," too. In this episode, biologist Andrew Ray shows us that a little creature can tell us a lot about the Yellowstone ecosystem. Music by Chad Crouch, Victrola Dog/Podington Bear Music
Why parks record sound
The NPS Natural Sounds and Night Skies Division monitors soundscapes in parks across the United States. Natural quiet is treated as a resource to protect, like clean air or dark skies: noise from aircraft, vehicles and machinery can mask animal communication and change the experience of a place.
