Episode Details

In Galicia, Spain, a wild comeback is underway: native Cachena cows—tiny, agile “goat-cows” that eat anything—are helping fight wildfires by grazing down flammable undergrowth. After a devastating 2025 wildfire season, communities revived these hardy animals, along with sheep and goats, to naturally manage overgrown land that’s become a fire hazard. Once nearly extinct, the Cachena population has surged from 400 to 8,000, and total native livestock in the region has jumped from 1,800 to over 30,000. GPS collars let them roam free, and the strategy is spreading across Spain—proving that nature, not machines, can be the best wildfire defense.
