Flashing Tags, Fewer Predator Losses

I always like a little bit of research to feature in our agricultural news and, if it's easy for me to grasp, all the better. This story is just that!

Large predators are a reality of the West, and while biologists study their place on the land, ranchers deal with real costs when livestock are targeted. Wolves, coyotes, bears and cougars sometimes prey on cattle and sheep, creating financial strain and emotional stress that can lead to lethal control.

In this latest round of research, Utah State University wildlife biologist Julie Young and her team examined a simple, nonlethal option called FlashTags. These motion-activated LED ear tags flash random light patterns at night, startling predators. The solar-powered units attach like standard ear tags and are designed to be low-cost and low-maintenance.

Researchers tested whether the lights bothered livestock and found no changes in sheep behavior or weight gain. When field-tested in areas with a history of wolf and coyote predation, losses were sharply reduced or stopped altogether. Nearly every producer involved reported fewer kills.
