Flashing lights ward off livestock-hunting pumas in northern Chile

A new paper reports that Foxlights, a brand of portable, intermittently flashing lights, kept pumas away from herds of alpacas and llamas during a recent calving season in northern Chile.

Herds without the lights nearby lost seven animals during the four-month study period.

The research used a “crossover” design, in which the herds without the lights at the beginning of the experiment had them installed halfway through, removing the possibility that the herds were protected by their locations and not the lights themselves.

Pulsating lights placed around llama and alpaca herds warded off puma attacks during a recent experiment in Chile, suggesting the method might help avert conflict between herders and dwindling populations of the predator.

“The implications are huge,” Omar Ohrens, a postdoctoral scholar in environmental studies at the University of Wisconsin, Madison, and lead author of a study on the findings, said in an interview.
