The study, released March 15, concludes that there is no significant increase in stress levels among wildlife due to recreational aviation activity.
Overseen by RAF’s Environmental Science Advisory Committee chair Dr. Ric Hauer – Ph.D. of the University of Montana’s Institute on Ecosystems – U of M post-graduate wildlife biologist Devin Landry selected a suite of six Montana and Idaho backcountry airstrips; and six control sites devoid of aircraft noise. Volunteer RAF pilots flew the scientists and their equipment in to the airstrips to collect feces samples, which indicate stress levels through hormone excretions. After laboratory analysis, Landry and Hauer published an 18-page document subjected to peer-review. Titled “Effects of Backcountry Aviation on Deer Stress Physiology.” It summarizes:
