Gracie on the Job: How This Border Collie Is Protecting Glacier National Park’s Wildlife

The National Park Service is going to try a low-tech way to keep bighorn sheep and mountain goats away from tourists at Glacier National Park in Montana. Instead of drones, GPS locators or electric fences, Gracie the border collie is on the job as she herds wild animals away from parking lots, trails, and buildings.

Sheep and goats see dogs as a natural predator. The park service tried yelling, shouting and waving arms at sheep as they get close to humans and their cars at Logan Pass within the park.

She also represents a way to control wildlife without killing any animals or harming any humans.
