The galloping 'firefighters'

The wildfires that used to burn each summer in the woods above the Spanish village of Barro have diminished to almost none since Lucia Perez started grazing wild horses there.

"There used to be fires every year, but since 2019, when we started coming here, we've had one small fire in the first year and nothing since," said Perez, 37, explaining how by clearing the undergrowth between the trees the horses help stop fires igniting and spreading.
