Urge the Air Force to conduct low-level overflights outside of Wilderness

The U.S. Air Force (USAF) is proposing to expand its military training airspace over Wilderness in the Owyhee Canyonlands of southwestern Idaho and the Jarbidge Wilderness in northern Nevada, with low-level flights by supersonic fighter jets known as F-15E Strike Eagles. This proposal is just one of many to expand military activities across the country. Such activity would shatter the area’s natural sounds, ruin the wilderness experience for visitors, and stress native wildlife

The USAF is currently accepting public comments on its Airspace Optimization for Readiness at Mountain Home Air Force Base draft Environmental Impact Statement (EIS). More than 13,000 of our members and supporters spoke up during the last public comment period, and we need you to speak up again now! Comments are due September 22.

The Owyhee Canyonlands region has 516,000 acres of Wilderness in the Pole Creek, North Fork Owyhee, Little Jacks Creek, Big Jacks Creek, Bruneau-Jarbidge Rivers, and Owyhee River Wildernesses, and is important wildlife habitat for a broad variety of species. For one, this is some of the best habitat in the country for greater sage-grouse, whose population is in steep decline mainly due to livestock grazing and mining. The region is also home to bighorn sheep, pronghorn, elk, cougars, badgers, river otters, raptors, rare snails, and threatened bull trout. The Jarbidge Wilderness is one of the most remote spots in the lower 48 states and one of the least visited Wildernesses. An unusually wet area for Nevada, its vegetation varies from northern desert plants to alpine plants. Elk and mountain lions call the Jarbidge Wilderness home. 

Currently, an out-of-court settlement restricts low-level supersonic military overflights in most, but not all, of the Wilderness in the Owyhee Canyonlands. The proposed action, which is the one most likely to be accepted, would keep that agreement in place, but it would negatively affect places outside of the agreement area, like the Jarbidge Wilderness, by allowing low-level supersonic flights. Low-level flights occur in the North Fork of the Owyhee Wilderness and should be ended. 

Research documents the serious health effects of aircraft noise, including low-level supersonic jet flights, on humans and wildlife—such as auditory damage and startling response. For example, studies show that greater sage-grouse are sensitive to the stress caused by extreme sound disturbances, which can impact their ability to successfully feed, mate, nest, and raise their young. And for people who seek quiet and solitude in the Jarbidge and Owyhee Canyonlands Wildernesses, military training exercises are always at odds with experiencing such values of Wilderness and should be prohibited. 

The Air Force should avoid Wilderness for overflights, especially low-level flights as there are more appropriate locations for low-level flights by supersonic jets. At the very least, Wilderness and its wildlife should be protected by keeping current restrictions on low-level overflights in the area, and by expanding these restrictions to include the Jarbidge Wilderness and all Wildernesses in the Owyhee Canyonlands.

Please write in your own words, but consider including the following points:

Please accept my comments on the Airspace Optimization for Readiness at Mountain Home Air Force Base draft Environmental Impact Statement (EIS).

  • I’m opposed to your proposal to expand military training airspace over designated Wilderness in the Owyhee Canyonlands of southwestern Idaho and the Jarbidge Wilderness of northern Nevada. Overflights, especially low-level flights by supersonic fighter jets, would shatter the area’s natural sounds, ruin the wilderness experience for visitors, and stress native wildlife.
  • The Owyhee Canyonlands region has 516,000 acres of Wilderness in the Pole Creek, North Fork Owyhee, Little Jacks Creek, Big Jacks Creek, Bruneau-Jarbidge Rivers, and Owyhee River Wildernesses, and is important wildlife habitat for a broad variety of species. For one, this is some of the best habitat in the country for greater sage-grouse, whose population is in steep decline mainly due to livestock grazing and mining. The region is also home to bighorn sheep, pronghorn, elk, cougars, badgers, river otters, raptors, rare snails, and threatened bull trout. The Jarbidge Wilderness is one of the most remote spots in the lower 48 states and one of the least visited Wildernesses. An unusually wet area for Nevada, its vegetation varies from northern desert plants to alpine plants. Elk and mountain lions call the Jarbidge Wilderness home.
  • As you know, an out-of-court settlement restricts low-level military overflights in most, but not all, of the Wildernesses in the Owyhee Canyonlands. While the Proposed Action would keep the settlement agreement in place, current operating restrictions outside of the Owyhee Canyonlands, like those affecting the Jarbidge Wilderness, would be greatly weakened.
  • Research documents the serious health effects of aircraft noise, including low-level flights by supersonic fighter jets, on humans and wildlife, such as auditory damage and startling response.  For example, studies show that greater sage-grouse are sensitive to the stress caused by extreme sound disturbances, which can impact their ability to successfully feed, mate, nest, and raise their young. And the low-level flights could harm bighorn sheep (already seriously threatened by disease) by forcing them to abandon important habitat. And for people who seek quiet and solitude in the Jarbidge and Owyhee Canyonlands Wildernesses, military training exercises are always at odds with experiencing such values of Wilderness and should be prohibited.
  • I’m urging the U.S. Air Force to ‪keep existing above ground-level restrictions in place, and better yet, to use other, more appropriate non-Wilderness locations for overflights, especially low-level supersonic flights. Wilderness and its wildlife should be protected by keeping current restrictions on overflights, and by expanding these restrictions to include the Jarbidge Wilderness and all Wildernesses in the Owyhee Canyonlands.

Thank you for considering my comments.
