In early 2017, multiple deadly forest fires swept the country Chile. As a result of these fires, 11 people lost their lives, wholes towns disappeared from the map, and over a million acres of wildlands burned. The aftermath of forest fires not only destroys lives but also devastates local flora and fauna.

Animals leave due to lack of food, invasive species take over, and the ground lies barren. Usually, nature heals itself over the course of many years. For some regions in Chile, though, a special team of working dogs is out to lend nature a helping hand.

Border Collies Save the Day After Forest Fire

Dog trainer Fransisca Torres and owner of the environmental NGO Pewas decided to put her 3 Border Collies to work doing an important job — reseeding the Chilean forests. All 3 dogs are female and they’re named Das, Olivia, and Summer. Each of the dogs wears a backpack designed to allow seeds to scatter as the dogs run. Torres drives to the day’s work location and releases the dogs from the truck.

They run through the forest leaving seed trails in their wake. Being Border Collies, they can rack up some impressive mileage each day — close to 20 miles each, in fact! Furthermore, they can scatter close to 20 pounds of seeds. Most humans who reseed the forests after fires average 5 miles per day and oftentimes far less. After the packs are empty, the dogs return to their handler for love, treats, and a refill. Once their packs are restocked, they’re off again.

The efforts have already started to pay off — regrowth is occurring much quicker in the regions the dogs have ran. Greenery and vines are already starting to show. The efforts by Torres, Das, Olivia, and Summer have been praised by the president of Chile and multiple organizations dedicated to environmental preservation and awareness.
