Giant Drones Airlift Straw to Save Fire-Ravaged Spanish Mountains

León, Spain – Heavy-lift drones are flying bundles of straw onto steep, fire-scarred mountainsides in northwestern Spain to keep the blackened soil from washing away in the rain.

Footage released on October 21 by Naturaleza Castilla y León, the regional government's environment account, shows crews on the ground loading netted bundles of straw that drones then carry up over charred, rocky slopes in the Burbia river basin in the province of León.
