The galloping 'firefighters'

Galicia's regional government acknowledged the role wild horses play in preventing forest fires and preserving ecosystems, but said the current legislation was adequate for their conservation because the horses can generate an income (for their owners) by being sold or through tourism during the rapa das bestas, meaning "shaving of the beasts", a Spanish festival.

"Although these animals are bred in the wild, in reality they have an owner and there is an economic benefit," the government said in an emailed statement.
