This episode is based on an interview with Kurt Fristrup PhD, the senior acoustic Specialist with the National Park Service’s Natural Sounds Program in Fort Collins, Colorado. He talks about the effect of noise on predator-prey relationships, animal communications, and on human physiology. Fristrup reveals some of the findings on the acoustic health of Yosemite as well as some interesting discoveries made possible through recordings made in the wilderness.

Low intensity fire in Yosemite  

Did You Know?
Natural fires in Yosemite are often no more than a single burning snag (standing dead tree) or a slow moving, low intensity fire that cleans underbrush from the forest floor. These fires prevent unwanted fires by removing accumulating forest debris that can fuel a larger fire in hot, dry conditions.
