DNR law enforcement outlines evidence needed to investigate thermal and drone use in hunts

Major Chad Vetridge of DNR law enforcement updated the Utah Wildlife Board on enforcement challenges tied to drones, thermal-imaging and other night-vision devices.

Vetridge summarized the regulation: "A person may not use any night vision device or device capable of night vision while taking, locating or attempting to locate any big game between July 31, December 31," and said the devices encompass thermal imaging, infrared imaging and other electronics that enhance visible or nonvisible light. He told the board the division receives frequent reports but often lacks sufficiently specific evidence to locate pilots or prove unlawful use.

Officers have opened investigations across regions; Vetridge said some incidents stem from ignorance of the rule, while others appear intentional. He asked the public to provide actionable information — photos and video, GPS locations and license-plate details — and cautioned people not to place themselves in danger trying to intervene.

Board members asked what constitutes an unlawful "take"; Vetridge clarified that possession of a thermal device in the field during the closed period, combined with an action to shoot or attempt to take an animal, can constitute an unlawful take even if the animal is not retrieved.

Vetridge also acknowledged the practical difficulty of finding drone pilots in remote terrain and said law enforcement is developing new techniques to investigate the incidents and enforce existing rules.

No regulatory change was proposed at this meeting; the board accepted the informational update and encouraged ongoing public reporting.
