Frequent low-altitude flights can disrupt the feeding and breeding habits of wildlife and livestock. Many of the health impacts to humans, including stress, will be felt by animals, too. Some of the most significant impacts from noise on wildlife are caused by chronic exposure. The timing of proposed flight training over the course of a year could affect game species and, therefore, hunting and fishing in the Gila, which has some of the state’s best elk herds and most sought-after hunting permits.
